Code of Practice



As part of the ABC Waters Programme, integration of adjacent watercourses with proposed developments is encouraged, whilst satisfying the engineering requirements for drainage functions without posing any public safety, maintenance or environmental problems. These include, but are not limited to:

(a) Enhancing the accessibility or connectivity to waterbodies/waterways, eg. creating community spaces for adjacent to watercourses and providing boardwalks to bring people closer to water, etc.;
(b) Providing aesthetic treatment to waterways, eg. use of a more natural finish such as block pitching or imprints on canal walls, planting along the canal walls  etc.;
(c) Installing ABC Waters Design features to detain and treat storm water runoff closer to the source (seeInstalling ABC Waters Design features to detain and treat storm water runoff closer to the source (see Section 8.2 for further details).


Qualified Persons together with the owners/developers can significantly enhance the development by incorporating into their designs appropriate ABC Waters Design features as described in the ABC Waters Design Guidelines (2nd Edition) published by the Board on 6 July 2011 (available at http://www.pub.gov.sg/abcwaters/abcwatersdesignguidelines/Documents/ABCWatersDesignGuidelines_2011.pdf). These guidelines were developed based on the following principles:-

(a) Protection and enhancement of natural water systems within the development site; 
(b) Integration of stormwater treatment into the landscape by incorporating multiple-use corridors that maximise the aesthetics and recreational amenities of developments; 
(c) Improvement of quality of water draining from the development into receiving environment. For example, through effective filtration and retention measures, runoff from the site can be treated to remove pollutants and silt, thereby protecting the water quality in waterways downstream;
(d) Reduction of runoff and peak flow from the development site by implementing local detention measures and minimizing impervious areas;

The designs of the aesthetic waterbodies, waterways and safety barriers need not be constrained by the standard features as shown in this Code of Practice as long as these facilities fulfill the drainage requirements and do not give rise to any public safety, maintenance or environmental problems.


The approval of the competent planning authorities shall also be sought for all such proposals. Where appropriate, the aesthetic waterbodies and watercourses shall be integrated into the development proposals and be maintained by the developers/owners of these developments.
