Catchment management

The catchment approach

In a catchment, rainfall not used by plants either infiltrates into the groundwater or as surface run off; eventually flows into surface water systems such as streams rivers, lakes and the ocean.

Agriculture, forestry, industry, waste management and water abstraction all have an impact on the catchment and on the quality of the water within it.

We are active participants in local catchment partnerships, working collaboratively with multiple stakeholders, and working with landowners and farmers in our priority areas on best practice and catchment improvements.

The quality of raw water in our region is generally very good; however, there are some substances used in agriculture that are persistent in the environment and that pose a risk of exceeding the prescribed levels in raw water. We are working with farmers to manage these risks, with a focus on two substances which have an impact on our water supplies.
