The Demonstration Test Catchments (DTC) project is a joint Defra, Environment Agency (EA) and Welsh Assembly Government initiative working in three river catchments – the Wensum in Norfolk plus the Eden (Cumbria) and Avon (Hampshire).

The overall objective of the project is to provide evidence to test the hypothesis that it is possible to cost effectively reduce the impact of agricultural diffuse water pollution on ecological function while maintaining food security through the implementation of multiple on-farm measures across whole river catchments using local expertise to solve local problems.

The River Tamar, in addition, has been adopted as an official satellite to the Hampshire Avon DTC. This expansion is supported by DEFRA and provides an opportunity to assess the water quality and freshwater responses to mitigation strategies funded by South West Water via the Payment for Ecosystem Services scheme being implemented by the Westcountry Rivers Trust.
