Reedbed Technology provides cutting edge, environmentally sustainable wastewater management.

Reedbed Technology

Reedbed Technology’s passive water treatment systems are an environmentally sound, cost effective alternative to mechanical treatment systems. The innovative design behind Reedbed Technology works to streamline routine maintenance, reducing overall power consumption.

Reedbed’s sustainable model reduces operating costs by 80% and carbon emissions by 90% compared with conventional wastewater systems. Reedbeds are an alternative form of wastewater treatment, using constructed wetlands, as opposed to mechanical treatment systems, to manage water in a more environmentally sustainable way.

Reedbeds allow for the sustainable treatment of domestic wastewater, wastewater sludge, industrial wastes, leachate and contaminated groundwater, mining and industrial process water, and winery and agricultural wastewater. Reedbed Technology focuses on creating water management solutions that complement the surrounding landscape, preserving the ecological balance and adding aesthetic appeal.
