Private Water Supplies in Argyll and Bute

Argyll and Bute’s towns and villages are supplied by reservoirs operated by Scottish Water (like the Craignafeoch Reservoirs). If you live in Argyll and Bute your water and sewerage services might come from Scottish Water, the cost of which is included in your council tax bill, or you could be serviced by a private supply.

However, some rural parts of Argyll and Bute operate on a private water supply. This means that their water comes from a spring, borehole, well, river or loch rather than Scottish Water.

Many properties in Argyll and Bute are on a private water supply, many of which are known as Regulated Supplies, providing water to residential properties of over 50 occupants, Airbnbs, factories and rented cottages.

New Scottish legislation states that landlords who rent out entire properties or single rooms within a house that uses a private water supply, have a legal duty to ensure the health and safety of their tenants by testing their water supply.

While it’s your responsibility to maintain and manage your private water supply, the quality and quantity of the water provided is monitored by your local council.

In Argyll and Bute there are approximately 3,500 private water supplies serving over 8000 inhabitants and many more visitors.

All private water supplies must be registered with the Council who are continually updating their existing register.

You can request your supply is sampled by Argyll and Bute Council via their website.

It’s the law for landlords in Argyll and Bute, or premises managers, to conduct Legionella Risk Assessments on your holiday lets, Airbnbs or any other residential lettings. Tenants have a right to know they’re drinking from a private water supply and failure to comply with new Scottish Government legislation means you could face hefty fines or imprisonment.

A Legionella Risk Assessment will find impurities in your water and suggest how to prevent contamination in the first place.

What a Legionella Risk Assessment isn’t:

A Legionella Risk Assessment won’t fix the risks identified in your water supply. You will need to book further water treatment to ensure your supply is hygienic and safe for human consumption. The Argyll and Bute Council website and HSE provide more information and advice.

If you’re a landlord or own commercial properties in Argyll and Bute that feed on private water supplies, you have a legal responsibility to test the water. A risk assessment isn’t necessary if your private water supply is for a domestic property, although you do have a duty of care towards those in your household who use the water supply.

Any property in Argyll and Bute not served by Scottish Water will be on a private water supply. This means water comes to your property from a borehole, spring, well, burn or loch.

Many remote parts of Scotland, such as the Highlands and Islands, rely on private water supplies for their drinking water. Roughly 3% of Scots’ water comes from a spring or borehole instead of being provided by Scottish Water. It’s the responsibility of property owners to regularly test their water supply to ensure it’s safe to drink.

In Scotland, private water supplies are defined as those that are not provided by Scottish Water. Private water supplies are either commercial or domestic and there’s different rules for each.

If carefully managed, a high standard of drinking water can be maintained from a private supply. However, there are serious health risks if water treatment is neglected. E-coli, Legionella and other harmful bacteria can easily breed in dirty water tanks if you’re not careful.

The ‘Water Intended for Human Consumption (Private Supplies) (Scotland) Regulations 2017’ came into effect in 2017. These new regulations require private water supplies to be risk assessed once every 5 years and sampled annually. Your local council can carry out a risk assessment and will charge you for this service.

Small domestic water supplies, where all the properties are owner occupied, are exempt from these new regulations.

On a private water supply you might run low or run out of water completely. Scottish Water can provide you with water in such emergencies and you’ll have to arrange this with your local council. If you think something is wrong with your current supply don’t drink the water. Use bottled water and wait until a professional has identified the source of the problem.
