Mayflower Water Treatment Works (South West Water)
Commissioned by South West Water and officially opened in 2020, the Mayflower Water Treatment Works replaces the aging Crownhill plant in Plymouth. Serving about 250,000 residents , it meets increased urban demand and tightens regulation.
The project introduced a groundbreaking combination of technologies (SIX®, ILCA®, CeraMac®) following a pilot at Crownhill (2013–2015), addressing key challenges such as:
-
Delivering a compact, low-footprint footprint design in a constrained site
-
Removing dissolved organic carbon (DOC), pesticides, and microorganisms to meet stringent water quality standards
-
Reducing chemical usage, energy costs, and operating expenses
-
Ensuring reliable long-term operation and automatable performance

Sharp’s Brewery Wastewater Treatment Plant
Context
To support its growing production and reduce environmental impact, Sharp’s Brewery in Rock, Cornwall, invested in a sustainable wastewater treatment solution. As the first brewery in South West England to adopt UASB technology, Sharp’s aimed to turn wastewater into a resource—recovering energy and reducing its liquid waste footprint. The brewery needed a compact, efficient, and future-ready system that aligned with its environmental ambitions.
Solution
Nijhuis Saur Industries (NSI), part of Saur Group, designed, built, and commissioned a turnkey wastewater treatment plant for Sharp’s Brewery. The system includes a curved screen for spent grain recovery, a flocculation-flotation (DAF) unit for solids removal, and an AECOMIX™ UASB reactor for anaerobic digestion. A flash aeration step removes hydrogen sulfide before discharge. The biogas produced is reused on-site, supporting Sharp’s sustainability goals and reducing reliance on external energy sources
