Private water supplies
A private water supply is any water supply which is not provided by a water company. The source of the supply may be a spring, well, borehole or a surface derived supply. A supply may serve several properties or commercial or public premises.
All private water supplies in Wales are regulated under the Private Water Supplies (Wales) Regulations 2010.These regulations require the Council to monitor:
- Large commercial supplies (all commercial supply and large domestic supplies – over 50 people): We will monitor these supplies regularly and carry out a risk assessment every 5 years.
- Small domestic supplies (less than 50 people but supplying more than one property.) We will carry out a risk assessment and sampling every 5 years.
- Single property supply (only one property): these are exempted from the regulations, but we can carry out a risk assessment and sampling on the owner/ occupant’s request.
Remember! If you’re supplying other people with water, with or without a fee (e.g. other domestic properties, holiday let, caravan park, camping site etc), it is your responsibility to ensure that the water is healthy and that is doesn’t pose a risk to people’s health.
If you need us to take a sample your water supply, contact us:
The results will be sent to you within 28 days. We will provide an explanation of the results and advise you on how to rectify any problems identified.
The regulations allow local authorities to charge owners of private supplies for undertaking various activities or duties required by the regulations.

Private distribution system
When a private water company supplies water to a property/site boundary, and the person responsible for that property distributes water through a third party line to other properties on the site – for example business parks, caravan parks, collage campus. In these instances a risk assessment must be carried out to establish a sampling schedule for the site.
