Water quality is checked at every stage on its journey to your taps to ensure that the water is always safe to drink.
The water is checked at our water desalination plants, it is again checked when it reaches our storage reservoirs located within the rock at the Waterworks. It is checked again before it is supplied into our service reservoirs (from where supplies are continually provided to customers taps). Final checks are undertaken when it leaves the service reservoirs and at the point of delivery i.e at the tap.
Our results are checked by the Government's competent authority, the Environmental Agency. They do this to make sure we are operating our water treatment works and distribution system in a way that doesn't put your water supply at risk.
The tests we undertake substantially exceed the minimum quantity of tests that we are required to undertake under the European Directive. This allows our pass rate to be higher than the United Kingdom’s national average.
