Rehabilitation of Wastewater Treatment Plant Ponds

⁠⁠⁠Maranoa Regional Council (MRC) invites suitably qualified and experienced Contractors to submit a lump sum tender, based on a schedule of rates pricing and supporting documentation for the rehabilitation of Council's Sewerage Treatment Plant (STP) Ponds at Roma Qld 4455.

The pond banks are eroding away and the access tracks in between the ponds are becoming narrower. The project will comprise of the rehabilitation of the northern train of three ponds followed by the southern treatment train of three ponds to address the following issues:

• Inadequate aeration affecting treated effluent quality; and
• Wave damage and erosion of the embankments of the sewage treatment ponds.

In order to address item (a), MRC have acquired and installed aerators into two ponds. These aerators will need to be temporarily relocated and then reinstalled as part of the proposed works.

This project addresses item (b) the bank erosion issues at Roma STP by remediating the pond embankment walls and installing a 2mm thick HDPE liner on the sidewalls.
