Most private water supplies in Scotland comply with drinking water standards but a significant minority need to make further improvements, according to the latest report from Scotland’s Drinking Water Quality Regulator (DWQR).
In 2015, a total of 42,361 tests were taken from Type A private water supplies – those serving more than 50 people or a commercial activity. Of these, 95 per cent met the required standard. However, 12.3 per cent of samples taken from Type A supplies for E. coli last year did not comply with the standard, which indicates they are not receiving the appropriate treatment necessary to make the water safe. There has been a small improvement on last year’s figure of 13.4 per cent.
Around 3.4 per cent of the Scottish population receive their water from a private water supply rather than from Scottish Water. The care and maintenance of these supplies is the responsibility of the owners and users. Some of these supplies serve hotels, tourist accommodation and other businesses.
