Why are wetlands needed to treat stormwater and effluent.
Constructed wetland water basins can be used to treat waste from sludge dewatering when constructed alongside Sewage Treatment facilities, landfill leachate, mine drainage, stormwater catchment, and agricultural activities.
Constructed wetlands provide a sustainable way to treat polluted water with minimum operation and reduced cost.
The impermeable layer which forms the water basins is usually made of clay that prevents the filtration of waste down into the lower aquifers. Unfortunately, the correct type of clay is seldom available in sufficient quantity where the wetland and/or storm basins are needed.
With our innovative RoadCem methodology the placement can be almost anywhere and with little material being moved on and off site, transport planning and local disruption is kept to the minimum.
With a recent project we carried out at South Elmsall lorry movements were reduced by over 3,000 trucks and a new 650m access road and two bridges were no longer needed.
No sand, stone or other natural resources were needed and more importantly no plastic liners were required.
With this strong, impermeable durable technology the maintenance of the basins will be safe and simple and at end of life all the RoadCem bound soils will be100% recycleable.
Construction with RoadCem involves excavation, and grading, of the land to achieve the desired hydraulic flow patterns. Followed by excavation and forming of the water basins.
This should make constructing of a wetland a cost-effective and technically feasible approach for treating wastewater and controlling/containing storm water that is not only saves cost and time to construct but also has low operational and maintenance costs.
When compared to other wastewater treatment methods, it is aesthetically pleasing alternative that eliminates the odours associated with traditional wastewater treatment.
