Our expertise includes passive and aerated reed bed design and construction.
Typically this involves combining treatment and optimum storage solutions in CSO (Combined Sewer Overflow) projects.
Land Treatment Areas, or Grass Plots are used widely in the U.K for tertiary polishing.
NWS have undertaken many reed bed refurbishments. Generally, we remove the gravel and wash it on site whilst recycling the wash water and dewatering the collected solids.
