To minimise the impact of flooding, PUB has introduced new measures into its revised Surface Water Drainage Code of Practice which takes effect from 1 June.
Going forward, all new and redevelopment projects with a land area of 0.2ha and above will be required to control flow of rainwater into public drains coming from development sites during intense storms.
Among the measures that could be used by developers to manage excess stormwater include design features such as rain gardens and structural features like green roofs and detention tanks. This could mean a substantial reduction of rainwater flowing into drains from about 90 to 35 percent after such green features are implemented.
“Based on the historical data that we have recorded so far in the last 30 years, there has been an increasing trend in rainfall, and projections for the future are also likely to show an increase in rainfall patterns. We are not only tackling the source, but also the pathway and the receptor, and so these features will actually help to improve the flood resilience and increase the flexibility and the adaptability of our drainage system to meet our future challenges," said Tan Nguan Sen, PUB’s director for catchment and waterways.
Developers will be given a grace period of six months within which to implement their on-site stormwater management strategies.
