New Sewer Trunk Main and New Inlet Pump Station

Project Progress

Council Report 2 November 2020 - Sewer Trunk Main and Inlet Pumping Station Procurement

Project Scope

To cater for existing and future effluent and sewer flows to Council’s Mount Barker Wastewater Treatment Plant (WWTP), a new sewer trunk main and inlet pump station is required from Hampden Road to the WWTP on Springs Road.

Sewer Trunk Main and Inlet Pump Station Location Map

The new trunk main (1 metre in diameter) will be the largest sewer pipe installed to date by Council, as will be the new inlet pump station at 14 metres deep and 6 metres in diameter.

Construction of the new trunk main will make redundant the existing siphons and pump station located in the reserve at the rear of Bernhardt Court. These particular assets have required servicing every six months in the early hours of the morning, causing unavoidable disruption to surrounding properties. Construction of the new trunk main will eliminate the need for this servicing.

Construction is planned to commence around April 2021 with an anticipated completion around February 2022.

It is not yet known what the construction methodology will be.  As part of the assessment of tender submissions in early 2021, consideration will be given to construction impacts and the minimisation of these relative to cost.

It is anticipated that during construction there are likely to be some restrictions to access for the linear trail from the rear of St Francis de Sales College to the WWTP. Every effort will be made to minimise such restrictions and to maintain access to the linear trail where possible, however site safety for trail users and the contractor’s staff will be Council’s and the contractor’s main priority.

The successful contractor will need to develop and submit to Council for approval an Environmental Management Plan, to ensure the local environment such as the Mt Barker Creek, flora and fauna are protected during construction activities.

Your understanding and patience during this essential upgrade to Council’s Wastewater Network will be greatly appreciated.

If you have any questions or would like to discuss any aspect of these works, please feel free to contact Council’s Project Manager Wastewater, Damian Lethbridge, on telephone 8391 7241 or email council@mountbarker.sa.gov.au
