Unitywater is set to construct a new gravity main in Caloundra, Queensland, as part of a larger project to upgrade the city’s sewerage system.

Unitywater will build a new main from First Avenue, under Bowman Road, along Park Place, with a branch reaching under the Caloundra Waterfront Holiday Park.

Simon Taylor, Executive Manager, Infrastructure Planning and Capital Delivery at Unitywater said the works are part of a wider project to improve Caloundra’s sewerage network.

“Sewage overflows in very wet weather have been a problem in this area in the past. These works will increase the sewerage network’s capacity to manage this problem and will improve operational performance to cater for a growing population.

“Unitywater has chosen tunnelling technology rather than open trenching to lay the new mains because we wanted to minimise the disruption to the community, traffic and the holiday park,” Mr Taylor said.

While drilling will minimise disturbance to the road network, Unitywater’s contractor will set up work sites at various stages at the locations.

“Some lane closures will be unavoidable, however we’ll work hard to keep it to a minimum,” Mr Taylor said.

Works are expected be completed by early December 2016.

Following the expected completion of these works, Unitywater will decommission an existing sewer pump station located within the Caloundra Waterfront Holiday Park.
