Overview

Developed by PUB, the ABC Waters Design Guidelines provide reference to developers and industry professionals on how to implement environmentally sustainable green features or ABC Waters design features in their developments. This is part of PUB’s effort to get partners from the 3P sectors to jointly work on a common vision of sustainable water management.

The Latest Edition

PUB has released updated edition of guidelines which was launched by Senior Minister of State for Ministry of Sustainability and the Environment, and Ministry of Transport, Dr Amy Khor on 21 June 2024, in conjunction with the Singapore International Water Week 2024. The updated edition highlights exemplary projects from both public agencies and private developers that successfully adopt the ABC Waters concept. This set of reference material aims to better serve the industry’s needs and continue to build up technical expertise in the industry.

The Engineering Procedures for ABC Waters Design Features, which forms an integral part of the ABC Waters Design Guidelines, provides detailed guidance on how to design, construct and maintain these features.

Design Templates

PUB has launched a template for ABC Waters Professional to submit the design calculations for vegetated swale, bioretention swale and bioretention basin (also commonly known as rain garden). This template specifies the exact parameters which PUB requires in the review of the DC submissions. This template does not replace the standard design reports and drawings associated with the ABC Waters design features.

Effective 1 June 2022, all DC submissions by Qualified Persons (QP) for vegetated swales, bioretention swales and bioretention basins (also known as rain garden) are to be accompanied with the templates below:

Bioretention Basin Bioretention Basin_v1.2.xlsx
Vegetated Swale Vegetated Swale_v1.1.xlsx
Bioretention Swale Bioretention Swale_v1.1.xlsx


Other ABC Waters design features, such as constructed wetlands, soak-away raingardens, cleansing biotopes, etc., not mentioned above are currently not covered by this requirement.
