Problem 

Due to an insufficient drop in the stormwater outlet running into the harbour, high tides and periods of heavy rain was causing backflow up the outlet pipe, which resulted in surface flooding of the low-lying areas around the city centre. 

Solution 

A 1300mm flanged WaStop valve was installed in the stormwater outlet pipe to prevent tidal floodwaters from entering the stormwater system and enable the pipe system to be used for stormwater retention during high tides.
