Earth Control Measures

Singapore has two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers, storm-water collection ponds and reservoirs before it is treated for drinking water supply. Thus, it is of paramount importance to keep waterways and reservoirs clean.

After a heavy downpour, the waterways often turn brown. This is because silt gets washed down from exposed earth surfaces and construction sites. To tackle the problem of silty discharge, PUB has been working with the construction industry on concerted efforts in public education and engagement, technology upgrading, and enforcing good earth control measures.

To promote awareness, PUB jointly held seminars with the Construction Industry Joint Committee (CIJC), a grouping of eight associations in the construction industry, on erosion and sediment control.

To provide guidelines on earth control, PUB revised its Code of Practice on Surface Water Drainage in 2007 to provide best practices on earth control measures (ECM) at worksites. Along with the revision, building contractors have been required to register an ECM plan with PUB, designed and endorsed by a Qualified Erosion Control Professionals, and implement the ECM plan before the start of any construction work.

The 4th edition of the Singapore Contractors Association Limited(SCAL)-PUB ECM guidebook, published in Oct 2014, is available for download.
