Wastewater treatment technology and solutions specialist Jacopa has been awarded the contract to design, manufacture, deliver, install and commission 10 of the company’s Copa Standard 200mm and 250mm waterwheel distributors for Thames Water’s Cholsey wastewater treatment works.
The contract was awarded by the eight2O alliance [see below], which is delivering £1.7 billion of essential improvements to Thames Water’s ageing network over the AMP 6 period.
Cholsey village is situated just south of Wallingford in Oxfordshire nd its gravity-fed treatment works has 12 trickling filters.
Converting the site to double filtration requires six of the distributors to be fitted into the primary systems and the remaining four into the secondary beds.
The distributors will be mounted onto the existing support flanges, and horizontal galvanised steel flow arms will distribute the raw wastewater onto the water wheel turbines.
Waterwheel distributors can improve the performance of humus tanks and the quality of the treated effluent by providing a smooth, continuous flow through the filter media, says the company. The installation will take place in stages to ensure the works remain fully operational during the upgrade.
Alex Lloyd, Jacopa managing director said: “We are delighted to have won this contract, and look forward to working with eight2O on one of Thames Water’s vital upgrades.”
- eight2O is the largest alliance in the water sector. The partners involved are Thames Water and two design and build joint ventures made up of Costain, Atkins, Black & Veatch (CABV); and Skanska, MWH and Balfour Beatty (SMB). MWH also leads programme control and IBM is the technology innovation partner. The alliance brings together global expertise from multiple sectors – including Thames Water – aligned around a common set of outcomes and a shared vision.
