THE ISSUE

WE ONLY HAVE RAINWATER

Singapore does not have any significant, accessible natural aquifers, which are layers of underground rock that are able to hold water. Instead, we rely on reservoirs for collecting and storing rainwater.

To make the best use of the rainfall we receive, the water catchment area in Singapore has been progressively expanded over the years. An extensive network of drains, canals, rivers and storm water ponds collects and channels rainwater to our reservoirs for storage.

THE CHALLENGE

Reservoirs Chanllenge

DIFFICULT TO CREATE NEW RESERVOIRS

All major estuaries in Singapore have already been dammed up to create reservoirs. While we still have some untapped streams and rivulets near the coastline, they are too small to dam up as reservoirs.

RAINFALL PATTERNS ARE UNPREDICTABLE

Climate change may affect rainfall patterns. This makes it difficult to make plans to meet the water needs of our population and economy.

POSSIBLE POLLUTION FROM URBAN DEVELOPMENT

Singapore’s small size means that much of our urban development is near or within water catchment areas. Many human activities produce pollutants that can be carried via the drainage system into our reservoirs when it rains.

OUR EFFORTS

MAKING OUR RESERVOIRS VERSATILE

Apart from serving as water collection and storage spaces, our reservoirs also provide valuable recreational space.

Some reservoirs are now open to a variety of water sports such as canoeing, dragon-boating, kayaking and sailing.

KEEPING OUR WATER CLEAN

We have put in place measures to keep our reservoirs clean. For example, an underground wall was built along the former Lorong Halus landfill, which forms part of the bank of Serangoon Reservoir. The wall prevents water from the landfill from entering the reservoir.

SEEKING COOPERATION FROM PRIVATE AND PUBLIC SECTORS

We rely on everyone to help keep our water clean. Construction companies have to ensure that soil does not get washed into our drains from worksites and factories have to ensure that waste chemicals are not discharged into our drains. Individuals also have to help keep our drains, rivers and reservoirs clean by not littering.
