Your water quality report
For water quality monitoring and reporting purposes our supply area is divided into 20 water supply zones. We produce an annual summary report for each zone, including test results for substances such as bacteria, nitrate, pH, taste and lead. Average water hardness figures are added to the report.
To access the report for your area, simply click on the map or use the boxes below to search by full postcode or supply zone.
We recommend you read our customer information sheet, "Your water quality report explained". It explains the layouts of the reports and what the different terms mean.
