Royal HaskoningDHV has developed a range of small package plants based on its award-wining Nereda® wastewater treatment technology with biological phosphorus removal to help water companies meet new AMP 7 phosphorus consent requirements.
The tightening of water consent for phosphorus removal on smaller wastewater treatment works, with hundreds of wastewater treatment sites and ecosystems affected, is a key challenge for water companies in AMP 7.

In response, the company has teamed up with three specialist contractors, Suprafilt, Eliquo Hydrok and EPS, to ensure a UK-wide turnkey delivery of the Nereda Package Plants.
The new Plants provide high-quality sustainable wastewater treatment with biological phosphorus removal at small works serving between 300 and 10,000 people. For added efficiency, the Package Plants have been designed to be manufactured, assembled and pre-tested off-site, which allows for a highly cost-effective implementation, ensuring improved health and safety and an efficient site assembly, even under the current COVID-19 restrictions.
Chemical-free phosphorus removal
René Noppeney, Global Director Nereda at Royal HaskoningDHV explained:
“With the new AMP 7 phosphorus consent challenges, the timing was right to introduce the Nereda Package Plants. The alternative of continued dependency on high levels of chemical dosing for years to come is simply not sustainable. Our Nereda technology provides chemical-free phosphorus removal. We are offering a new delivery model too and have partnered with three leading specialist contractors to ensure fast, efficient and safe delivery to all water companies across of the UK.”
The Nereda Package Plants have been developed to provide a competitive and sustainable solution, offering the lowest whole-life cost solution for small works.
David Armstrong, Managing Director at Eliquo Hydrok commented:
“We are delighted to be part of this initiative to deliver standardised and sustainable wastewater treatment plants for small works, and we’re looking forward to discussing the solution with our customers.”
In addition to meeting the tightening phosphorous removal requirements, the plants can achieve high levels of ammonia and total nitrogen removal too. A key benefit of the plants is the potential for speedy implementation. It is possible for a Package Plant to progress from award to full operation within just 24 weeks, with onsite assembly, testing and process start-up taking just four weeks. Patrick Buckley, Managing Director at EPS Water added:
“It is important for us to offer the best whole-life solution. Being able to provide turnkey delivery of Nereda Package and Mini Plants – including factory build and pretesting, transport to site, assembly and process start up – will mean we can help water companies meet present and future consents.”
Royal HaskoningDHV’s award-winning Nereda® wastewater treatment solution is already being applied on six continents for municipal and industrial water. It is an established game-changer for sustainable wastewater technology, with over 80 projects completed or being delivered across the world and 14 wastewater treatment works in the UK.
