The solution
Nereda wastewater technology was selected by United Utilities for improved wastewater treatment at Morecambe. C2V+ was the project’s delivery partner for the overall catchment solution, including a £17 million upgrade at the WWTP. Nereda process designers at Royal HaskoningDHV worked in collaboration with the project’s construction partners, to refine the design to meet its specific challenges. Three new 4,000m³ Nereda reactors have been installed within the footprint of the existing plant, with the capacity for treating a peak flow of 2,360 m³/hour of wastewater. The Nereda installation is upstream of the existing sand filter tertiary treatment stage, while a new UV disinfection plant has also being installed, together with treated water storage to avoid discharge at low tide. The fact that Nereda technology does not require final settlement tanks was one of the reasons the process was chosen for this project, as space constraints meant that site area at Morecambe WWTP was limited. As part of the wider £70 million Lancashire project, a new 7km sewer pipe now runs from Schola Green Pumping Station, under a railway line, around the perimeter of Morecambe FC football ground, across the A683 Heysham Bypass into Morecombe Treatment Works. A tidal pumping system also serves the works as part of the new design.
