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.


If you want more detailed information about the quality of drinking water in your local area please contact the Company. Their telephone number is 01244 320501.

     


The Drinking Water Inspectorate checks that your drinking water is properly tested and that action is taken to put right breaches of standards. The results of the tests given overleaf have been carefully audited and give an accurate picture of the quality of water supplied by the company.

Drinking water standards in England and Wales include all those in the European Community Directive on drinking water and are mainly based on levels recommended by the World Health Organisation. Those of significance to health have generally been set with a wide safety margin. The occasional breaches of the standards which have happened do not mean the water was not suitable for drinking.

The Inspectorate assesses each breach of the standards and if necessary requires water companies to give legally binding undertakings to carry out improvements.

The summary of the 1995 Report gives the results of tests for England and Wales as a whole and sets out in more detail how the quality of your drinking water is checked and the significance of each of the listed substances.
