Singapore establishes itself as a “hydrohub” in Asia

22.06.2015

Water resource management is a major challenge for Singapore, a city-state with a population of more than five million. Despite high rainfall, there are few water resources, and the State does not have any natural storage spaces or aquifers. To deal with these constraints, the city has developed an innovative water management policy.

Singapore is an especially innovative city in terms of water management. As it hosts Singapore International Water Week every year, an important event for professionals in the sector, the city recently announced different initiatives to better meet the challenges facing it.
On 15 June, the PUB (Public Authority Board), the authority in charge of water management on the island, signed a memorandum of understanding with SUEZ environnement to facilitate the sharing of know-how and to develop new technologies. The agreement calls for three research projects centred on water and energy consumption.

Faced with periods of intense rainfall, the city will experiment with the INFLUX software developed by SUEZ environnement to implement a system of dynamic rain water management to avoid the risks of saturation and thus of flooding, or the risk of polluting the natural environment.
A second focus will concern the optimisation of energy consumption by wastewater treatment by reducing the consumption of the energy necessary for the treatment process, and also by increasing the recovery of energy from the sludge.
Finally, users will be directly involved in efforts to reduce water consumption, thanks to automated meter reading, which will enable them to follow their consumption in real time.

Along with these projects, the city is considering new methods to store rain water underground. Given the risks related to climate disruptions (increase in rainy periods and droughts, etc.), storing rain water would indeed increase the amount of available water resources. .

All these initiatives demonstrate the city’s ambitious goal of reaching water self-sufficiency by 2060 and reducing its energy dependence.
