Question

how water catchment contributes to the water supply in Singapore.

Answer 1

Sustainable water supply in Singapore owes local catchment methodology since the growing water catchment area helps to meet both domestic and non-domestic water demand. Two-thirds of land surface in Singapore strives to collect every drop of water in the Marina, Punggol and Serangoon Reservoir. Local catchment system collects both used water and rainwater. For instance, rainwater is managed through a comprehensive network of drains, canals, and rivers, and after that, it is directed to the reservoirs before it is treated for drinking water. Another method is collecting used water in a network of underground sewers leading to a water reclamation plant.
