Disadvantages of Conventional System

Benefits of an Integrated Constructed Wetland

  • High Infrastructure Costs

    Both the initial capital outlay and the ongoing maintenance requirements

  • Constant Use of Chemicals

    In a world increasingly more aware of environmental risks and challenges, highlighting green credentials is a critical part of a companies marketing persona

  • High Operational & Maintenance Costs

    High energy costs of running a WWTP with associated maintenance costs

  • Low Running Costs

    Whilst there is still an initial capital outlay for a wetland, the long term maintenance and running costs are greatly reduced

  • Environmentally Friendly

    Not only does an ICW use no chemicals to process waste, the surrounding area of the wetland is aesthetically pleasing and blends with its surrounding

  • Reduced Carbon Footprint

    In a time of taxed carbon emissions why not reduce your carbon footprint with an ICW!
