Your water comes from many sources

Water is found from different places before being collected, treated, and then pumped through many kilometres of pipes to your home.
428 Lakes, reservoirs and rivers

  • Collecting and storing water is the first stage of delivering water to customers. 

    Water is obtained from lakes, reservoirs, rivers or underground sources.  Although there are more underground sources, most of the water that companies collect comes from lakes, reservoirs and rivers.

    This untreated water is then pumped to water treatment plants. In some cases, the untreated water is stored in reservoirs – this helps with the treatment process as large particles sink to the bottom. 

    The amount of water that companies can take out of rivers or underground sources is controlled by the Environment Agency and Natural Resources Wales.
