Two final settlement lagoons required a little refurbishment, including repairs to the outfall structure and the installation of an EPDM liner to each lagoon, and replacement pipework.
As framework contractors for Wessex Water as well as approved installers of Firestone lining products, we tendered for the work and were successful.
We liaised with the Environment Agency and prior to the drain down of the lagoons, our fisheries team attended site and completed an eel rescue.
The lining works comprised of re-grading the beds and sides of the lagoons and digging an anchor trench around the perimeter of each lagoon to secure the liner. The liners were then installed complete with pipe penetrations and geotextile protection. With the liners in place the new connecting pipe work, control equipment, and access chambers were installed.
Much of the digging had to be done by hand, due to the limited access around the lagoons. This work was carried out while the lagoons were out of commission.
