Local Catchment Water |

The 1st National Tap
As a small island that doesn't have natural aquifers and lakes and with little land to collect rainwater, Singapore needs to maximise whatever water it can harvest.
Currently, Singapore uses two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers and stormwater collection ponds before it is channelled to Singapore's 17 reservoirs for storage. This makes Singapore one of the few countries in the world to harvest urban stormwater on a large scale for its water supply.
The newest reservoirs are Punggol and Serangoon Reservoirs which are our 16th and 17th reservoirs. Combined with Marina Reservoir which has the most urbanized catchment of 10,000 hectares, Punggol and Serangoon Reservoirs will increase the water catchment areas from half to two-thirds of Singapore's land area.
