Liverpool's water comes from a managed network of reservoirs, rivers, and aquifers, operated by United Utilities:
Rain and snowmelt collected, treated, then piped to Liverpool.
Dee Water Treatment Works (near Chester) treats 275 million litres/day, pumped to Liverpool.
Underground aquifers (porous rock/sand) provide naturally filtered water.
United Utilities ensures safety, reliability, and wastewater treatment across the North West.
