Project Overview

Hilltops Shire Council is developing a Rural Fire Services complex and Showground Pavilion development in Harden. A Design and construct Water main extension and Sewage Pump Station is required to transfer wastewater generated at the two complexes to the council sewage system and potable water supply to the RFS building and new Showground Pavilion.
