Water and wastewater solutions provider ACWA Services have started 2017 with three new design and build contracts for nitrate removal plants worth in excess of £3 million, including a new solution for Cambridge Water at Fowlmere WTW.

All plants will utilise ACWA’s highly successful ion exchange Nitreat technology, already deployed at 27 water treatment works (WTW) in the North and East of the country to ensure drinking water quality in line with DWI quality targets, within Nitrate Vulnerable Zones (NVZ).

For lead contractor Integrated Water Services (IWS) work is due to commence at Cambridge Water’s Fowlmere WTW to the south of Cambridge in September. The new plant, which follows the completion of projects for Cambridge Water at Babraham, Euston and Fleam Dyke, is designed with sufficient capacity to treat a raw water flow of 5,400m3 per day from onsite boreholes, reducing nitrate levels of 79.6mg/l to produce a final blended water flow with nitrate levels at 43mg/l.

ACWA is responsible for process, mechanical, electrical and instrumentation works, through to commissioning for all three projects. IWS will also be responsible for civil works including the treatment building and work is expected to be completed in June 2018.

Commenting on the new contracts Peter Brewer, ACWA Services’ UK General Manager said:

“Our 30th contract for Nitreat marks a great start for 2017. The system is already bringing significant operational benefits for our UK water industry customers and full compliance with water quality standards. Rising nitrate levels are a continuing issue and through a programme of continuous improvement we are working hard to ensure highly reliable, low cost solutions to meet demanding cost efficiency objectives and rigorous discharge limits.”
