Willoughby City Council – Warners Park creek restoration, rock infiltration dam, GPT and stormwater harvesting pumpwell

Optimal Stormwater were engaged by Willoughby Council to undertake the design and construction of creek restoration, rock infiltration dam, a GPT and stormwater harvesting pumpwell at Warners Park, Northbridge. Optimal Stormwater designed and documented the works, including design of a new CDS GPT suitable to the catchment size of 60 ha. Natural rocks were used from the GPT excavation to restore the creek and create the rock infiltration dam which would naturally and eventually create a wetland upstream.
