Wastewater from the town of Keswick (around 5,000 residents) is treated at Keswick Water Treatment Works. Phosphorous recovery is in operation here by dosing with iron sulphate. This removes around 50% of phosphate before the treated water enters Bassenthwaite Lake. United Utilities are currently undergoing an upgrade which should see the levels of phosphate removed rise to 80%. Nevertheless, it is not possible for all the phosphate to be removed so it’s better if we don’t put it down the plughole in the first place!
