This greenfield subdivision on the outskirts of Goolwa required extensive consultation with the local council.
The existing CWMS scheme was already at capacity and there was no existing stormwater discharge location. Civil design made provision for a large stormwater channel behind the proposed subdivision to divert stormwater to a detention basin and on to a wetland. Stormwater flow from roads was resolved by balancing the use of swales and collection points. As Council was creating new infrastructure to serve the greater Goolwa area, Council requested a vacuum sewer system which is unusual in this State.
The system resolves issues associated with groundwater levels affecting sewer construction.
Greenhill staff trained with FloVac to understand and apply the operating and design principles.
Three stages have been constructed and another three have been designed.
