Catchment management

Human activity can cause small amounts of pollutants in water bodies which may appear minor whilst on their own, but in combination can play a key role in influencing raw water quality. 

A catchment is a defined area of natural landscape that collects precipitation and contributes to a body of water, such as an aquifer or river. A variety of activities can impact water quality. Whether it’s the operation of wastewater treatment plants or the maintenance of household septic tanks, from the chemicals used by factories to the use of fertilisers by homeowners. Some of the possible pollution sources are highlighted in the image below.

undefinedThus, both industry and the community can be involved in minimising the concentration of pollutants in our raw water. This is why we aim to collaborate with local businesses and communities within catchments to encourage best environmental practice and ensure a supply of high-quality water.
