Wrexham Water plc supplies drinking water to about 150,000 people living in and around the town of Wrexham. Most of the Company's water comes from the River Dee with nine reservoirs, one spring and one borehole providing the rest. The Company has seven treatment works and distributes water through a network of 1,350 km of pipes and 27 service reservoirs.
Each year water companies are inspected. The 1995 inspection found that the Company's arrangements for analysis and reporting were generally very good and that treatment processes were satisfactory. Five recommendations for improvements in practices were made.
The quality of the water supplied by the Company in 1995 has been generally very good. 99.8% of the 12,191 tests performed by the Company met the standards - the tests were largely made on samples taken from consumers' taps. Of the small number of tests that did not meet the standards some were for coliform and other indicator bacteria. Each time these bacteria were detected the cause was investigated and any problems identified were corrected. The Inspectorate has identified that further work will be required at two service reservoirs and the Company has given a commitment carry out this work. The only other significant failure to meet the standards was for aluminium which is covered by the Company's improvement programmes.
The graph above shows the continued good water quality over the past five years. The Company, as it must, plans to improve the quality even further. It has given legally binding commitments to take steps to improve two service reservoirs and its water mains. The work at the service reservoirs will be complete by August 1996. The Company is going to replace or repair its old mains in some areas, this work is a long term project.
