Southern Water’s water recycling pilot plant was developed to provide evidence in support of, and to inform, Southern Water’s final permit application.

The Environment Agency (EA) will determine what permitting standards are required for environmental protection in line with existing legislation.

The EA will expect Southern Water to comply with any permit that is agreed to allow them to discharge recycled water into Havant Thicket reservoir.
