A Scottish Environment Protection Agency (Sepa) report warned that current water levels in parts of Moray are at “significant scarcity” due to the spell of high temperatures and the local council said some people have seen their private springs run dry.
Although the vast majority of Scotland has access to public water supplies, nearly 4 per cent of the population rely on private water supplies and the Scottish Government last week released funding to councils to help those affected by the shortage.
There are more than 800 private water supplies in Moray serving about 4,825 properties. Moray Council said free bottled drinking water can be collected in Elgin and Aberlour. The council is also looking at ways to connect remote communities to the mains water supply if the issue remains and said grants could be made to create new supplies.
Highland Council has also issued advice to private supply users.
