Cheema is a UK authority on the design, installation and operation of reedbed systems, either as a stand-alone system or as a tertiary polishing prior to discharge into a watercourse.

Applications include the treatment of sewage, industrial effluent, landfill leachate and sludge, surface water, stormwater and mine drainage.

Reedbeds are also used for watercourses, lakes and reservoirs, and the company has particular expertise in surface run-off for airports.

Systems include:
• Vertical and horizontal subsurface-flow reedbeds.
• Overland-flow constructed wetlands, grass plots and inclined planes.
• Facultative lagoons and maturation ponds.
• SUDS systems and macrophyte reed rafts.
• Ecologically engineered aerated lagoons.
• ReedFurb^™ for in-situ cleaning and refurbishment of reedbeds without the need to dig out the media (patent pending).

Cheema is a turnkey provider of Restorer^® aerated lagoons for sewage and industrial effluent treatment, which can extend desludging intervals to 10 years.
