United Utilities has hired LiMA to deliver an upgrade to its Kendal Wastewater Treatment Works. The upgrade, which leverages Nereda water purification technology, will see the plant treat people equivalent of 93,000 – and be the largest plant in the UK to use the technology. LiMA will work closely with consultancy firm Royal HaskoningDHV, and the technology provider for the project.
Formed in 1995, following the merger of North West Water and Norweb, United Utilities (UU) is one of the UK's largest water companies, providing the regulated water and waste water network in North West England – servicing around 7 million people.
One of the assets operated by the United Utilities is the Kendal Wastewater Treatment Works. As part of the plans to upgrade the treatment plant, a plant designed to treat a people equivalent of 93,000, the company signed a delivery contract with LiMA.
To boost the plant’s capacity, LiMA has turned to Royal HaskoningDHV as the provider of Nereda*, a water purifying technology. The deployment of the technology at the plant makes it the largest user of the technology in the UK. UU was the first UK company to trial the technology at its Davyhulme treatment works – where the now congenital activated sludge was developed 100 years earlier.
Rene Noppeney, Global Director for water products & innovation at Royal HaskoningDHV, says, “Kendal Wastewater Treatment Works is a great opportunity to demonstrate how Nereda technology can deliver high quality effluent standards, low power requirements and sustainable costs.”
Mark Studholme, Director at LiMA, adds, “We are delighted to provide the engineering expertise delivering Nereda as the next generation wastewater treatment technology to our client. Combined with our in-house capabilities for digital and DfMA engineering the delivery of this innovative solution will ensure that the project meets all its outcomes.”
Other Nereda-based sites
The technology has been introduced at a range of other sites, supported by expertise from Royal HaskoningDHV, including at the Ringsend wastewater treatment plant in Ireland, the Deodoro wastewater treatment plant in Rio the Janeiro and at projects in Switzerland and India.
* Nereda is a technique for water purification, based on a technological solution which uses aerobic granular mass. The technology uses less energy than current systems and has a small footprint. The technology, developed in the Netherlands, took twenty years to develop and perfect, and provides a leap forward for water treatment options.
