Chester Waterworks Company supplies drinking water to about 107,100 people living in and around the City of Chester. Almost all of the Company's water comes from the River Dee with one borehole providing the rest. The Company has two treatment works and distributes water through a network of 563 km of pipes and three service reservoirs.

Each year water companies are inspected. The 1995 inspection found that the Company's arrangements for analysis and reporting were generally good and that treatment processes were satisfactory. Two recommendations for improvements in practices were made.

The quality of the water supplied by the Company in 1995 has been generally very good. All of the 5,160 tests performed by the Company met the standards - the tests were largely made on samples taken from consumers' taps.


The graph above shows the continued very good water quality over the past five years. The Inspectorate considers that it is not possible to improve water quality based on current standards. As a result the Company has not given any legally binding commitments to improve quality further.
