Water Quality Laboratory

In 2002 Jersey Water completed the development of its new laboratory at its depot in Millbrook, St Lawrence. Here the Lab team undertake the majority of the Company’s physical, bacteriological and chemical analysis using the latest equipment and testing processes.

The laboratory consists of a preparatory room with auto-claves for sterilisation of sample bottles and equipment, a bacteriological laboratory and chemical laboratory. The laboratory uses membrane type technology for bacteriological testing, which is more sensitive than the classic multiple tube analytical process.

Staff at the laboratory collect over 7,000 samples for testing each year, carry out quality assurance work on the Company’s new mains and also investigate customer queries regarding water quality.

The water quality results are verified against duplicate samples taken by the States of Jersey Analyst Department and Jersey Water’s independent consulting analyst’s laboratory, based in the South of England.
