A third of your drinking water comes from groundwater, which is the same as most bottled water. To access this natural source we have a host of sandstone aquifers across the Midlands. Put simply, an aquifer is underground layer of rock, gravel or sand, that water filters through. These large aquifers are boosted by smaller ones in the Cotswolds and Derbyshire area. We then drill boreholes hundreds of metres into the ground to reach this naturally filtered water. After years of being slowly filtered through the rock layers, the pumped groundwater needs very little treatment. Once it’s pumped to the surface, it's extremely close to your wonderfully clear water from your taps that we all know and love.
