Ebbtide Street - South Shore flood protection structure works

What

We are constructing new storm water backflow prevention structures.

Why

The existing backflow valves are prone to blockages and difficult to maintain so are being replaced with a new design.

Where

New backflow prevention structures are to be constructed over existing outfall pipes at Ebbtide St / Estuary Rd, Ebbtide St / Caspian St.

When

February 2022 to early June 2022. Work will be intermittent to align with tidal groundwater levels.(weather/site condition dependent).
