We’re the driest region in the UK, and with a fast-growing population, it's important that we monitor water resources closely to keep taps flowing and toilets flushing now and long into the future. That's why we're always exploring different ways to save and protect every drop.
The graphic below shows the current water resource levels across the region:

Water Sources
Around half the water we supply comes from groundwater sources (e.g. boreholes) and the other half comes from surface water sources (e.g. reservoirs and rivers).
Groundwater
Groundwater moves below our feet in rocks, with levels typically rising when temperatures and evaporation is low and soils are wet. The time taken for groundwater levels to respond to rainfall can range from hours to a few months, depending on the type of soil, rock and depth to groundwater. This water can be used by drilling holes (boreholes).
Reservoirs
We abstract water from rivers to fill our 8 large reservoirs around the region.
Rivers
As well as abstracting water from rivers for storage in our reservoirs we can also abstract water from rivers to get directly pumped to our treating and cleaning works (we call these direct river intakes). We help manage our water supply by taking care and protecting over 3,000 km of rivers.
Your local sources
We’re the largest water company by geographic area, and because the environments we cover are so different, some areas in our region may experience more challenges than others and react differently to weather conditions.
