What is FEWS – OMS Singapore?


23/38

What is the purpose?

• Integrated Water Quality and Quantity (flooding) system to

aid the operation of the Marina Reservoir and its Catchment

• Water quality decisions may influence flood risk• Operators need to be aware of influence of operation on

both water quality and risk of flooding.
