节约用水，人人有责 (Saving water is everyone’s responsibility)
We thank Shen Wenfeng (应考虑推行社区制水演习, 5 September) and Xu Yongshun (不要浪费水, 5 September) for their feedback.
Water is a precious resource, and we agree that we must all play our part to conserve it. Public education and community outreach helps to reinforce the reminder. One of PUB’s key initiatives is the annual Singapore World Water Day (SWWD), that is held in the month of March, and supported by schools, corporates and community groups organising various activities across the island to champion water conservation and water efficiency. Our “Make Every Drop Count” water conservation campaign held in conjunction with SWWD serves as a constant reminder for the public to rethink their water use and incorporate good water habits. This year’s campaign message – “Save water. Big ways, small ways. All OK! – centres on the simple actions one can take to collectively make a big difference. It included a community event at Jurong Lake Gardens and water-saving visuals and advertisements put up on multiple digital and out-of-home channels to raise awareness and educate public on water conservation.
Since 2016, we have also been working with schools to conduct water rationing exercises to teach students about conservation and the value of water.
In February, as part of Exercise SG Ready which took place over two weeks, hundreds of organisations and schools in Singapore simulated disruptions to various essential services including water to prepare for a civic emergency. On 26 February, PUB also partnered the grassroots to organise a water disruption exercise involving over 200 households in two HDB blocks. During the 2-hour disruption, PUB deployed our water wagons and distributed water bags, and residents were encouraged to bring their own containers to collect water. Participants also learned valuable lessons on how to respond during a water supply disruption through exhibit panels during the exercise.
Saving water is everyone’s responsibility, and we urge individuals and households to adopt water saving habits. Let’s all do our part to make every drop count.

Patrols against illegal fishing stepped up
We thank Mr Brandon Wong for his feedback ("Youths fished illegally and treated their catch badly", 2 May 2024).
At Lower Seletar Reservoir, prominent signages have been put up and CCTV cameras installed in the area to deter illegal fishing along the heritage bridge. PUB has stepped up monitoring and patrols by enforcement officers at Lower Seletar Reservoir and will not hesitate to take actions against offenders if spotted. Those caught fishing at no-fishing areas can be fined up to S$3,000.
We urge everyone to exercise consideration when fishing to ensure that our water bodies remain a safe and pleasant environment for all. It is important for the public to engage in fishing only at designated areas which have been selected based on factors such as pedestrian safety, as they must be located at a considerable distance from footpaths. Other actions include handling lures with care, practising catch and release, and properly disposing unwanted fishing lines, hooks and other litter in the provided bins.

Investment in research and technology crucial to create a sustainable future
We thank Mr Eric J. Brooks for his views on PUB’s plan to build a demonstration plant with Equatic and UCLA to explore carbon dioxide removal (CDR) from seawater (5 March 2024).
The United Nations’ Intergovernmental Panel on Climate Change has assessed that CDR will be a key contributor in limiting global warming to 1.5°C, and to offset emissions from difficult-to-decarbonise sectors.
The demonstration-scale plant is necessary to enable PUB and our partners to assess the potential of the ocean CDR technology for Singapore and beyond. Should the technology prove feasible for implementation at commercial scale, a single plant could potentially remove up to 110,000 metric tons of carbon dioxide per year — equivalent to the annual carbon emissions of more than 25,000 individuals and in the process produce hydrogen, a clean fuel source. This project is also part of the Government’s broader decarbonisation effort.
PUB is committed to investing in research and development and sourcing for best-in-class solutions to meet our target of achieving net-zero carbon emissions by 2045, thereby contributing to Singapore’s net zero targets. The investment will also be crucial in ensuring that Singapore’s water supply remains climate-resilient and sustainable.

Multi-functional, sustainable solutions key part of Singapore’s coastal protection efforts
We thank Mr Ryan Pang for his feedback on the need for more sustainable solutions for coastal protection (16 Nov 2023).
As Singapore’s national coastal protection agency, PUB is working with various stakeholders to develop effective measures that can protect our coastline from the impact of sea level rise and climate change.
Since May 2021, we have progressively commenced studies on different sections of Singapore’s coastline to understand their site characteristics and the types of potential coastal protection measures. These include the City-East Coast, North-west Coast and Jurong Island. Where feasible, we aim to develop solutions that can be integrated with existing developments and land use plans to achieve multiple benefits, such as co-location with recreational spaces for the community. One example is the Marina Barrage, a popular recreation venue which also serves its main purpose of keeping out seawater while enhancing flood protection in downtown Singapore.
Coastal cities such as Tokyo and Hong Kong have demonstrated that there is scope to balance environmental sustainability with the need for practical engineering measures to keep out the rising seas. This is achieved through hybrid solutions that combine nature elements, including planting of mangroves, seagrass or vegetation, with coastal infrastructure such as seawalls and revetments. While hybrid solutions can help enhance biodiversity, we must consider their suitability taking into account the site conditions along our coastline.
Earlier this year, PUB launched Singapore’s first research programme dedicated to coastal protection and flood management. It will foster greater collaboration across academia and the industry, spurring the growth of a vibrant research ecosystem. Under this programme, the Coastal Protection and Flood Resilience Institute Singapore was established as a multi-institutional and inter-disciplinary research centre, bringing together the strengths of our local universities and research institutes to develop innovative and sustainable solutions and build a pipeline of coastal protection talent.

PUB works with stakeholders to highlight importance of keeping waterways clean
We thank Mr Hong Tianming for his valuable feedback on the need for public stewardship of Singapore’s waterways and reservoirs (“国人不应污染水沟”, 19 Oct 2023).
Over the years, Singapore has developed an extensive network of about 8,000km of waterways and 17 reservoirs to expand our water catchment areas and meet our water supply needs.
Mr Hong has rightly pointed out that our drains and waterways serve important functions. They channel rainwater to the reservoirs before it is treated to become drinking water supplied to our homes. The effective conveyance of stormwater is also critical to prevent flooding during heavy rainstorms.
Collective efforts from everyone are necessary to keep our waterways free flowing and clean from pollution. As part of our public education efforts, PUB has involved the local community including schools, residents, and organisations to raise awareness on the importance of keeping our waterways clean. Our Active, Beautiful, Clean Waters (ABC Waters) Programme was also launched in 2006 to bring the public closer to water and foster stronger stewardship of our waterways. Since then, we have transformed many of our utilitarian drains and canals into beautiful spaces that integrate seamlessly with our living environment. Signages placed at these sites also remind people to take care of our precious water resources.
PUB will continue to work with relevant authorities and local community to educate the public on the importance of keeping our waterways clean and free flowing. Together, we can protect the quality of our water supply, and help prevent the occurrence of flash floods during intense rain.

Households that are more water efficient pay less
We thank Mr Christopher Leong Chi How for his feedback on the water tariff (Water tariff should be based on number of people in a household, Sept 30).
In Singapore, we price every drop of water to reflect its true cost. To encourage water conservation, we apply a higher-tier tariff only to water use that far exceeds the average household consumption. Currently, the higher tariff is set at a threshold of 40 cubic m of water per month.
Over 96 per cent of households in Singapore use less than 40 cubic m of water per month. In fact, a typical household of four uses an average of about 18 cubic m monthly.
A higher water tariff is applied only to the amount of water used above the 40-cubic m threshold. This is intended to send a strong signal against excessive use of water. All households pay the same tariff rate for the first 40 cubic m.
Households with the same number of people that are more careful with their water usage will pay less based on the amount of water used.
Given that the majority of households consume less than 40 cubic m a month and do not pay the higher-tier water tariff, we do not plan to adopt per capita charging that would incur higher administrative costs, which would ultimately be borne by all consumers, including more water-efficient households.
While we adopt right-pricing of water for all, targeted support is provided to lower- and middle-income households.
Besides the additional support measures announced recently by the Government to offset HDB households’ utilities bills, the Climate Friendly Households Programme will also be enhanced to include more efficient water fittings that can be bought with the vouchers. This will support households in achieving water savings.
Households can adopt simple habits, such as washing clothes on a full load and turning off the shower while soaping, to reduce daily water usage and their expenses on water.

Singapore’s water management system is innovative and land-efficient
We thank Mr Wu for his suggestion on adopting new used water recycling technology and optimising space by housing treatment facilities underground, citing a successful example in Shenzhen, China (交流站: 我国应善用水资源新技术, 25 Sep).
In Singapore, the same approach towards technological innovation and land efficiency applies in the planning and implementation of water infrastructure. Notably, we have transformed the way we manage our used water system with the Deep Tunnel Sewerage System (DTSS). Underground tunnels convey used water entirely via gravity to centralised water reclamation plants located near the coast, away from the city and residential areas.
The DTSS has been crucial in freeing up additional space previously occupied by used water infrastructure for other uses. When completed by 2026, it will result in total land savings of 150 hectares – nearly twice the size of the Singapore Botanic Gardens – by removing intermediate pumping stations and decentralised waste reclamation plants. For example, land that was housing the aged Seletar Water Reclamation Plant is now part of the Seletar Aerospace Park, a thriving aerospace cluster that has attracted over $1.5 billion worth of investments.
At our water reclamation plants, we have also leveraged new technologies to increase treatment capacity of used water while reducing our overall land footprint. With the use of new technologies, such as membrane bio-reactors, we have more than doubled treatment capacity while occupying a similar footprint of about 40 hectares at the Changi Water Reclamation Plant, compared to an older conventional plant in Ulu Pandan.
More importantly, the treated effluent is further purified into NEWater, Singapore's third National Tap. Recycling water in an endless loop has been a game-changer as it allows us to strengthen Singapore’s water resilience, especially amid the challenge of climate change.
In land-scarce Singapore, PUB has made it a point to incorporate multi-functional design into our water infrastructure where feasible. The Marina Barrage exemplifies this approach with its 3-in-1 benefits – besides serving its primary purpose of creating a freshwater reservoir in the city for water supply, it alleviates flooding in the low-lying areas of the city while also serving as a popular recreation venue for families.

Run-off at water park caused by high water pressure
We thank Mr Lee Ser Wei for his feedback on water run-off from the Play@Heights Park in Toa Payoh (Huge amount of water wasted at playground, Jan 9).
PUB and Bishan-Toa Payoh Town Council conducted on-site checks and determined that the water run-off into the drain was due to high water pressure at one of the park’s water features. The town council has adjusted the water pressure to rectify this issue.
In Singapore, water plays and water features use potable water. They are designed as closed systems to facilitate recycling and conserve water.

Different railing design due to safety concerns
We thank Mr Yao Qiliu for his feedback in his letter (“Coordinate materials and design to save public funds” 交流站：材料与设计应划一以节省公款, 4 November 2022). Public agencies do adopt the same design standards for common features, which may be updated over time.
The railings along the different sides of the open drain connecting Jalan Keli to Sin Ming Road were installed or upgraded at different points. While it originally had galvanised mild steel railings that run parallel on both sides, a short section of aluminium railing along the width of the drain was subsequently installed, in line with updated design standards, after the construction of a footpath across the drain.
In 2019, as part of planned upgrading works, PUB noted from public feedback and consultation with the Land Transport Authority that the adjacent footpath on one side of the drain is frequented by cyclists. To enhance safety, we installed higher 1.4m steel railings in line with the design update for public safety. As the existing galvanised mild steel railings on the other side of the drain were still in good condition, PUB took a prudent approach by retaining these railings to save public funds.

Railings will be replaced in February 2023
We thank Mr Xu for his feedback (“Rusted and damaged railings should be replaced”) 交流站：应更换生锈破损排水沟栏杆, 17 Nov 2022).
PUB carries out maintenance of drains and their appurtenances, including railings, as part of our routine inspections to ensure that they are able to function effectively and are safe for the public.
Mr Xu is referring to the stretch of railings along Bukit Batok East Avenue 2, Avenue 4 and Hillview Avenue, which covers 2.4 km along both sides of canal over four estates. Although some of the railings have peeled-off paint and rust, we would like to assure him that the railings have been inspected to be functional and safe.
We have been progressively replacing the railings in the four estates since 2021, as part of PUB’s ongoing railing replacement programme. The railings at Bukit Batok East Avenue 2 and Avenue 4 have already been replaced with the new railings. For the stretch of railings along Hillview Avenue, they will be replaced by February 2023. The new railings are also made of aluminium and will be more corrosion resistant and durable.

PUB replaces old drain gratings progressively as part of drainage maintenance and upgrading works
We refer to the letter by Yao Qiliu (“排水口格栅旁有缝隙”, 22 Sep 2022).
PUB has been progressively replacing existing on-road drain gratings as part of our drainage maintenance and upgrading works. Besides ensuring that these can effectively channel away stormwater from road surfaces, we also adopt the latest design to enhance safety for road users.
Replacement of the drain gratings is done in accordance with the latest design and standards, last revised by the Land Transport Authority (LTA) in 2011. The new design has grating bars that are perpendicular to traffic flow, and closer spacing between the drain grating and the road. This new grating design has been applied to all new road construction and drainage upgrading projects, and serves to reduce the risk of cycling accidents. Since 2011, PUB has replaced approximately 270,000 drain gratings with the improved design through our drainage upgrading works.
PUB will continue to work with the relevant authorities to review the current approach and prioritisation of upgrading works, and enhance public safety.

Canal enhancement design also depends on location and safety
We thank Ms Clara Ng for her feedback “Installed Features Prevent People Getting Closer to Water, 18 Aug 2022”. We are glad that Ms Ng enjoys spending time at PUB’s Active, Beautiful, Clean Waters (ABC Waters) sites.
The ABC Waters programme is PUB’s initiative to integrate drains, canals and reservoirs holistically into the urban environment with community spaces for all to enjoy. ABC Waters projects are rolled out progressively in conjunction with drainage improvement works.
PUB plans to improve the entire Bedok Canal progressively to increase the drainage capacity to cope with more intense rainfall and enhance the flood protection for the surrounding area.
We are currently upgrading the section of Bedok Canal between Upper Changi Road East and Bedok Junction and have incorporated ABC Waters enhancements along the canal to create new community spaces for the residents. As each ABC Waters site is different, the designs will also differ depending on several factors, such as site conditions and the safety of park users.
At Bedok Canal, the height of the railings installed along the canal are at the standard height of 1.1m. The railings along the footbridge across the canal on elevated ground are at 1.4m to protect both cyclists and pedestrians. The grey granolithic floor-screed was designed to provide slip resistance and safety for users.
PUB and NParks will endeavour to design and maintain each of our ABC Waters site with care so that members of the public can continue to enjoy these community spaces.

Gravel path at Pandan Reservoir a maintenance track for vehicular access
We thank Mr Leong Horn Kee for his letter “Reservoir area could be improved, 19 August 2022” .
The gravel track on the crest of Pandan Reservoir Dyke is a maintenance track used by PUB and our contractors for vehicular access to carry out maintenance works around the reservoir. Trees and shrubs are also not planted on the dyke to maintain the integrity of the dyke.
Jogging and cycling are allowed on the gravel track to provide community and recreational space to residents in the nearby estates. Residents can also utilise the nearby park connector networks (PCN) around Pandan Gardens and the West Coast area for recreation. We also welcome members of the public to visit the nearby Active, Beautiful, Clean Waters (ABC Waters) sites at Sungei Pandan, Sungei Ulu Pandan or Jurong Lake to enjoy the beautiful waterbodies and community spaces.

Rubbish bins at MacRitchie Reservoir Park cleared regularly
We thank Mr Chin Kee Thou for his feedback (Not enough rubbish bins at MacRitchie, 16 Feb 2022).
There are a total of 22 rubbish bins situated at popular locations around MacRitchie Reservoir Park – the majority of them are monkey-proof bins with heavy lids to prevent monkeys from opening them, which are cleared twice daily. We have also installed six "smart" bins equipped with sensors for remote monitoring of the bins' capacity, and cleaners are activated to empty a smart bin immediately once it reaches 80 per cent capacity.
Over the Chinese New Year period, PUB received increased feedback on littering within the park and has worked with our cleaning contractor to increase the clearing frequency of the bins and their surrounding area.
We encourage park-goers to dispose their trash into the bins as there were instances when trash was scattered around bins that were not full.
Let’s keep our parks clean and litter-free for all to enjoy.

Pedestrian safety a consideration when installing drain railings
We thank Mr Gopinath Menon for his feedback ("Have railings for open drains to protect pedestrians when flooding occurs", 7 Sept 2021).
Under PUB’s Code of Practice on Surface Water Drainage, railings must be installed at all open drains with a depth of more than 1 metre. In addition, we regularly review the necessity of installing railings at locations with high pedestrian traffic or within flood prone areas, even if the existing open drains there are less than 1 metre in depth.
Examples of such locations include Marigold Drive, Zion Road and Lorong Buangkok. PUB also considers public feedback and will install railings where feasible to ensure the safety of pedestrians.
When reconstructing open roadside drains as part of our ongoing work to upgrade Singapore's drainage infrastructure, PUB converts them into covered drains – which also double as footpaths – to optimise land use.
To facilitate maintenance access for covered drains, metal gratings or covers are installed along footpaths. These are fastened securely and are unlikely to be dislodged during flooding.
PUB will continue to review drain railing installations at different locations to enhance pedestrians’ safety.

Promoting water conservation a key facet of PUB's work
We thank the writers Mr Seah Yam Meng, Mr Philip Siow, Mr Ramamurthy Mahesh Kumar, Mr Tan Kim Hock and Mr Foo Kwang Sai for their feedback and suggestions on desalination and water conservation. It is heartening to know that water sustainability is a topic that is close to the heart for many and the strong awareness that we must never take water for granted.
PUB is committed to ensuring a diversified and sustainable water supply through our Four National Taps – catchment water, imported water, NEWater and desalinated water. NEWater and desalinated water have become increasingly important as they are weather-resilient sources that strengthen Singapore’s water security especially in the face of climate change. Our fifth desalination plant on Jurong Island is targeted to be ready later this year. Construction is ongoing for the second phase of PUB's Deep Tunnel Sewerage System – due to be completed by 2025 – which will further boost Singapore's used water recycling rate and enhance our ability to produce NEWater.
But even as we continue to build up our water production capabilities, demand for water will inexorably increase. Promoting water conservation remains a key issue that PUB has invested considerable effort, in the form of public education campaigns aimed at forging a strong water-saving culture in Singapore, and forums for industries to share their experiences in water recycling.
PUB has stepped up our efforts to reach out to households, businesses, industries and the youth. Since 2007, more than 350 industries and businesses have reduced their water demand by up to 50% through recycling efforts and water-efficient processes.
It is important that children cultivate good water habits from a young age. We worked closely with schools to hold water rationing exercises during our annual water conservation campaign, with students from over 100 schools taking part in March 2019. We recently launched a new mascot Water Sally alongside the iconic Water Wally, and a new storybook series to be distributed to close to 1,800 pre-schools for storytelling sessions in class. We also collaborated with renowned children’s education brand Pinkfong to produce a song to reinforce the value of water.
Over the last two decades, we have made significant strides in encouraging households to reduce their water consumption. In 2019, daily consumption stood at 141 litres per person. The goal is to reduce this to 130 litres by 2030.
This year, PUB’s water conservation campaign in March will focus on climate change and its impact on Singapore’s water sustainability. As pointed out by Mr Tan, every little bit helps – even small habits like turning off the shower while soaping can make a difference. Every individual can play our part to strengthen Singapore’s climate resilience by using water wisely and making every drop count.

We thank Mr Abu Mansor for his letter, “Wastage: Leaking pipe not fixed” (13 January 2021).
Upon receiving the feedback from Mr Mansor on 15 December 2020, PUB service crew went on site to Pandan Avenue and Pandan Road to investigate on the same day. However, the crew was unable to locate any pipe leak after checking all PUB’s pipes, valves and bulk meters in the vicinity. They tried contacting Mr Mansor several times to find out the precise location of the leak but were unable to reach him.
On 13 January 2021, PUB contacted Mr Mansor who provided additional information on the specific location of the leak. Our service crew went on site immediately and found the leaking service pipe belonging to a commercial building along Pandan Avenue. PUB informed the building management to repair the leak and the leak was rectified on the same day. PUB has updated Mr Mansor on the completed repair works and thank him for his feedback and assistance.
Under the Public Utilities (Water Supply) Regulations, premise owners are responsible for the proper maintenance of their service pipes and to ensure that there are no leaks. Any pipe leaks should be repaired promptly.
We encourage members of the public to contact PUB’s 24 hour call centre at 1800-CALL-PUB (1800-2255-782) to report any pipe leaks.

Coastal cities such as Tokyo and Hong Kong have demonstrated that there is scope to balance environmental sustainability with the need for practical engineering measures to keep out the rising seas. This is achieved through hybrid solutions that combine nature elements, including planting of mangroves, seagrass or vegetation, with coastal infrastructure such as seawalls and revetments. While hybrid solutions can help enhance biodiversity, we must consider their suitability taking into account the site conditions along our coastline.
Earlier this year, PUB launched Singapore’s first research programme dedicated to coastal protection and flood management. It will foster greater collaboration across academia and the industry, spurring the growth of a vibrant research ecosystem. Under this programme, the Coastal Protection and Flood Resilience Institute Singapore was established as a multi-institutional and inter-disciplinary research centre, bringing together the strengths of our local universities and research institutes to develop innovative and sustainable solutions and build a pipeline of coastal protection talent.

PUB works with stakeholders to highlight importance of keeping waterways clean
We thank Mr Hong Tianming for his valuable feedback on the need for public stewardship of Singapore’s waterways and reservoirs (“国人不应污染水沟”, 19 Oct 2023).
Over the years, Singapore has developed an extensive network of about 8,000km of waterways and 17 reservoirs to expand our water catchment areas and meet our water supply needs.
Mr Hong has rightly pointed out that our drains and waterways serve important functions. They channel rainwater to the reservoirs before it is treated to become drinking water supplied to our homes. The effective conveyance of stormwater is also critical to prevent flooding during heavy rainstorms.
Collective efforts from everyone are necessary to keep our waterways free flowing and clean from pollution. As part of our public education efforts, PUB has involved the local community including schools, residents, and organisations to raise awareness on the importance of keeping our waterways clean. Our Active, Beautiful, Clean Waters (ABC Waters) Programme was also launched in 2006 to bring the public closer to water and foster stronger stewardship of our waterways. Since then, we have transformed many of our utilitarian drains and canals into beautiful spaces that integrate seamlessly with our living environment. Signages placed at these sites also remind people to take care of our precious water resources.
PUB will continue to work with relevant authorities and local community to educate the public on the importance of keeping our waterways clean and free flowing. Together, we can protect the quality of our water supply, and help prevent the occurrence of flash floods during intense rain.

Households that are more water efficient pay less
We thank Mr Christopher Leong Chi How for his feedback on the water tariff (Water tariff should be based on number of people in a household, Sept 30).
In Singapore, we price every drop of water to reflect its true cost. To encourage water conservation, we apply a higher-tier tariff only to water use that far exceeds the average household consumption. Currently, the higher tariff is set at a threshold of 40 cubic m of water per month.
Over 96 per cent of households in Singapore use less than 40 cubic m of water per month. In fact, a typical household of four uses an average of about 18 cubic m monthly.
A higher water tariff is applied only to the amount of water used above the 40-cubic m threshold. This is intended to send a strong signal against excessive use of water. All households pay the same tariff rate for the first 40 cubic m.
Households with the same number of people that are more careful with their water usage will pay less based on the amount of water used.
Given that the majority of households consume less than 40 cubic m a month and do not pay the higher-tier water tariff, we do not plan to adopt per capita charging that would incur higher administrative costs, which would ultimately be borne by all consumers, including more water-efficient households.
While we adopt right-pricing of water for all, targeted support is provided to lower- and middle-income households.
Besides the additional support measures announced recently by the Government to offset HDB households’ utilities bills, the Climate Friendly Households Programme will also be enhanced to include more efficient water fittings that can be bought with the vouchers. This will support households in achieving water savings.
Households can adopt simple habits, such as washing clothes on a full load and turning off the shower while soaping, to reduce daily water usage and their expenses on water.

Singapore’s water management system is innovative and land-efficient
We thank Mr Wu for his suggestion on adopting new used water recycling technology and optimising space by housing treatment facilities underground, citing a successful example in Shenzhen, China (交流站: 我国应善用水资源新技术, 25 Sep).
In Singapore, the same approach towards technological innovation and land efficiency applies in the planning and implementation of water infrastructure. Notably, we have transformed the way we manage our used water system with the Deep Tunnel Sewerage System (DTSS). Underground tunnels convey used water entirely via gravity to centralised water reclamation plants located near the coast, away from the city and residential areas.
The DTSS has been crucial in freeing up additional space previously occupied by used water infrastructure for other uses. When completed by 2026, it will result in total land savings of 150 hectares – nearly twice the size of the Singapore Botanic Gardens – by removing intermediate pumping stations and decentralised waste reclamation plants. For example, land that was housing the aged Seletar Water Reclamation Plant is now part of the Seletar Aerospace Park, a thriving aerospace cluster that has attracted over $1.5 billion worth of investments.
At our water reclamation plants, we have also leveraged new technologies to increase treatment capacity of used water while reducing our overall land footprint. With the use of new technologies, such as membrane bio-reactors, we have more than doubled treatment capacity while occupying a similar footprint of about 40 hectares at the Changi Water Reclamation Plant, compared to an older conventional plant in Ulu Pandan.
More importantly, the treated effluent is further purified into NEWater, Singapore's third National Tap. Recycling water in an endless loop has been a game-changer as it allows us to strengthen Singapore’s water resilience, especially amid the challenge of climate change.
In land-scarce Singapore, PUB has made it a point to incorporate multi-functional design into our water infrastructure where feasible. The Marina Barrage exemplifies this approach with its 3-in-1 benefits – besides serving its primary purpose of creating a freshwater reservoir in the city for water supply, it alleviates flooding in the low-lying areas of the city while also serving as a popular recreation venue for families.

Run-off at water park caused by high water pressure
We thank Mr Lee Ser Wei for his feedback on water run-off from the Play@Heights Park in Toa Payoh (Huge amount of water wasted at playground, Jan 9).
PUB and Bishan-Toa Payoh Town Council conducted on-site checks and determined that the water run-off into the drain was due to high water pressure at one of the park’s water features. The town council has adjusted the water pressure to rectify this issue.
In Singapore, water plays and water features use potable water. They are designed as closed systems to facilitate recycling and conserve water.

Different railing design due to safety concerns
We thank Mr Yao Qiliu for his feedback in his letter (“Coordinate materials and design to save public funds” 交流站：材料与设计应划一以节省公款, 4 November 2022). Public agencies do adopt the same design standards for common features, which may be updated over time.
The railings along the different sides of the open drain connecting Jalan Keli to Sin Ming Road were installed or upgraded at different points. While it originally had galvanised mild steel railings that run parallel on both sides, a short section of aluminium railing along the width of the drain was subsequently installed, in line with updated design standards, after the construction of a footpath across the drain.
In 2019, as part of planned upgrading works, PUB noted from public feedback and consultation with the Land Transport Authority that the adjacent footpath on one side of the drain is frequented by cyclists. To enhance safety, we installed higher 1.4m steel railings in line with the design update for public safety. As the existing galvanised mild steel railings on the other side of the drain were still in good condition, PUB took a prudent approach by retaining these railings to save public funds.

Railings will be replaced in February 2023
We thank Mr Xu for his feedback (“Rusted and damaged railings should be replaced”) 交流站：应更换生锈破损排水沟栏杆, 17 Nov 2022).
PUB carries out maintenance of drains and their appurtenances, including railings, as part of our routine inspections to ensure that they are able to function effectively and are safe for the public.
Mr Xu is referring to the stretch of railings along Bukit Batok East Avenue 2, Avenue 4 and Hillview Avenue, which covers 2.4 km along both sides of canal over four estates. Although some of the railings have peeled-off paint and rust, we would like to assure him that the railings have been inspected to be functional and safe.
We have been progressively replacing the railings in the four estates since 2021, as part of PUB’s ongoing railing replacement programme. The railings at Bukit Batok East Avenue 2 and Avenue 4 have already been replaced with the new railings. For the stretch of railings along Hillview Avenue, they will be replaced by February 2023. The new railings are also made of aluminium and will be more corrosion resistant and durable.

PUB replaces old drain gratings progressively as part of drainage maintenance and upgrading works
We refer to the letter by Yao Qiliu (“排水口格栅旁有缝隙”, 22 Sep 2022).
PUB has been progressively replacing existing on-road drain gratings as part of our drainage maintenance and upgrading works. Besides ensuring that these can effectively channel away stormwater from road surfaces, we also adopt the latest design to enhance safety for road users.
Replacement of the drain gratings is done in accordance with the latest design and standards, last revised by the Land Transport Authority (LTA) in 2011. The new design has grating bars that are perpendicular to traffic flow, and closer spacing between the drain grating and the road. This new grating design has been applied to all new road construction and drainage upgrading projects, and serves to reduce the risk of cycling accidents. Since 2011, PUB has replaced approximately 270,000 drain gratings with the improved design through our drainage upgrading works.
PUB will continue to work with the relevant authorities to review the current approach and prioritisation of upgrading works, and enhance public safety.

Canal enhancement design also depends on location and safety
We thank Ms Clara Ng for her feedback “Installed Features Prevent People Getting Closer to Water, 18 Aug 2022”. We are glad that Ms Ng enjoys spending time at PUB’s Active, Beautiful, Clean Waters (ABC Waters) sites.
The ABC Waters programme is PUB’s initiative to integrate drains, canals and reservoirs holistically into the urban environment with community spaces for all to enjoy. ABC Waters projects are rolled out progressively in conjunction with drainage improvement works.
PUB plans to improve the entire Bedok Canal progressively to increase the drainage capacity to cope with more intense rainfall and enhance the flood protection for the surrounding area.
We are currently upgrading the section of Bedok Canal between Upper Changi Road East and Bedok Junction and have incorporated ABC Waters enhancements along the canal to create new community spaces for the residents. As each ABC Waters site is different, the designs will also differ depending on several factors, such as site conditions and the safety of park users.
At Bedok Canal, the height of the railings installed along the canal are at the standard height of 1.1m. The railings along the footbridge across the canal on elevated ground are at 1.4m to protect both cyclists and pedestrians. The grey granolithic floor-screed was designed to provide slip resistance and safety for users.
PUB and NParks will endeavour to design and maintain each of our ABC Waters site with care so that members of the public can continue to enjoy these community spaces.

Gravel path at Pandan Reservoir a maintenance track for vehicular access
We thank Mr Leong Horn Kee for his letter “Reservoir area could be improved, 19 August 2022” .
The gravel track on the crest of Pandan Reservoir Dyke is a maintenance track used by PUB and our contractors for vehicular access to carry out maintenance works around the reservoir. Trees and shrubs are also not planted on the dyke to maintain the integrity of the dyke.
Jogging and cycling are allowed on the gravel track to provide community and recreational space to residents in the nearby estates. Residents can also utilise the nearby park connector networks (PCN) around Pandan Gardens and the West Coast area for recreation. We also welcome members of the public to visit the nearby Active, Beautiful, Clean Waters (ABC Waters) sites at Sungei Pandan, Sungei Ulu Pandan or Jurong Lake to enjoy the beautiful waterbodies and community spaces.

Rubbish bins at MacRitchie Reservoir Park cleared regularly
We thank Mr Chin Kee Thou for his feedback (Not enough rubbish bins at MacRitchie, 16 Feb 2022).
There are a total of 22 rubbish bins situated at popular locations around MacRitchie Reservoir Park – the majority of them are monkey-proof bins with heavy lids to prevent monkeys from opening them, which are cleared twice daily. We have also installed six "smart" bins equipped with sensors for remote monitoring of the bins' capacity, and cleaners are activated to empty a smart bin immediately once it reaches 80 per cent capacity.
Over the Chinese New Year period, PUB received increased feedback on littering within the park and has worked with our cleaning contractor to increase the clearing frequency of the bins and their surrounding area.
We encourage park-goers to dispose their trash into the bins as there were instances when trash was scattered around bins that were not full.
Let’s keep our parks clean and litter-free for all to enjoy.

Pedestrian safety a consideration when installing drain railings
We thank Mr Gopinath Menon for his feedback ("Have railings for open drains to protect pedestrians when flooding occurs", 7 Sept 2021).
Under PUB’s Code of Practice on Surface Water Drainage, railings must be installed at all open drains with a depth of more than 1 metre. In addition, we regularly review the necessity of installing railings at locations with high pedestrian traffic or within flood prone areas, even if the existing open drains there are less than 1 metre in depth.
Examples of such locations include Marigold Drive, Zion Road and Lorong Buangkok. PUB also considers public feedback and will install railings where feasible to ensure the safety of pedestrians.
When reconstructing open roadside drains as part of our ongoing work to upgrade Singapore's drainage infrastructure, PUB converts them into covered drains – which also double as footpaths – to optimise land use.
To facilitate maintenance access for covered drains, metal gratings or covers are installed along footpaths. These are fastened securely and are unlikely to be dislodged during flooding.
PUB will continue to review drain railing installations at different locations to enhance pedestrians’ safety.

Promoting water conservation a key facet of PUB's work
We thank the writers Mr Seah Yam Meng, Mr Philip Siow, Mr Ramamurthy Mahesh Kumar, Mr Tan Kim Hock and Mr Foo Kwang Sai for their feedback and suggestions on desalination and water conservation. It is heartening to know that water sustainability is a topic that is close to the heart for many and the strong awareness that we must never take water for granted.
PUB is committed to ensuring a diversified and sustainable water supply through our Four National Taps – catchment water, imported water, NEWater and desalinated water. NEWater and desalinated water have become increasingly important as they are weather-resilient sources that strengthen Singapore’s water security especially in the face of climate change. Our fifth desalination plant on Jurong Island is targeted to be ready later this year. Construction is ongoing for the second phase of PUB's Deep Tunnel Sewerage System – due to be completed by 2025 – which will further boost Singapore's used water recycling rate and enhance our ability to produce NEWater.
But even as we continue to build up our water production capabilities, demand for water will inexorably increase. Promoting water conservation remains a key issue that PUB has invested considerable effort, in the form of public education campaigns aimed at forging a strong water-saving culture in Singapore, and forums for industries to share their experiences in water recycling.
PUB has stepped up our efforts to reach out to households, businesses, industries and the youth. Since 2007, more than 350 industries and businesses have reduced their water demand by up to 50% through recycling efforts and water-efficient processes.
It is important that children cultivate good water habits from a young age. We worked closely with schools to hold water rationing exercises during our annual water conservation campaign, with students from over 100 schools taking part in March 2019. We recently launched a new mascot Water Sally alongside the iconic Water Wally, and a new storybook series to be distributed to close to 1,800 pre-schools for storytelling sessions in class. We also collaborated with renowned children’s education brand Pinkfong to produce a song to reinforce the value of water.
Over the last two decades, we have made significant strides in encouraging households to reduce their water consumption. In 2019, daily consumption stood at 141 litres per person. The goal is to reduce this to 130 litres by 2030.
This year, PUB’s water conservation campaign in March will focus on climate change and its impact on Singapore’s water sustainability. As pointed out by Mr Tan, every little bit helps – even small habits like turning off the shower while soaping can make a difference. Every individual can play our part to strengthen Singapore’s climate resilience by using water wisely and making every drop count.

We thank Mr Abu Mansor for his letter, “Wastage: Leaking pipe not fixed” (13 January 2021).
Upon receiving the feedback from Mr Mansor on 15 December 2020, PUB service crew went on site to Pandan Avenue and Pandan Road to investigate on the same day. However, the crew was unable to locate any pipe leak after checking all PUB’s pipes, valves and bulk meters in the vicinity. They tried contacting Mr Mansor several times to find out the precise location of the leak but were unable to reach him.
On 13 January 2021, PUB contacted Mr Mansor who provided additional information on the specific location of the leak. Our service crew went on site immediately and found the leaking service pipe belonging to a commercial building along Pandan Avenue. PUB informed the building management to repair the leak and the leak was rectified on the same day. PUB has updated Mr Mansor on the completed repair works and thank him for his feedback and assistance.
Under the Public Utilities (Water Supply) Regulations, premise owners are responsible for the proper maintenance of their service pipes and to ensure that there are no leaks. Any pipe leaks should be repaired promptly.
We encourage members of the public to contact PUB’s 24 hour call centre at 1800-CALL-PUB (1800-2255-782) to report any pipe leaks.
