The Vertu Estate in Harrisdale features flush road curbing along Wright Road which allows stormwater to be treated in biofilters along the stream’s edge, before flowing into the Forrestdale Main Drain.
A number of the biofilters and detention basins have been integrated into the adjacent public open space to provide both stormwater treatment and amenity value to local residents.
