What is the WCI Free Upgrade Scheme?

WCI’s Free Upgrade Scheme offers eligible homeowners in Somerset a completely free replacement of their existing septic tank with a modern, fully compliant Graf sewage treatment plant. There is no cost to the homeowner for the installation. The scheme is funded by developers who need to purchase phosphate credits to satisfy nutrient neutrality planning conditions in the Somerset Levels and Moors catchment area. When WCI installs a new sewage treatment plant and decommissions the old septic tank, the improvement in wastewater treatment quality generates the phosphate credits that developers need.
