A private water supply is any water not provided by a water company and not considered "mains". The water can come from wells, boreholes, springs, rivers, streams, lakes and ponds. We monitor private water supply quality to make sure it's safe.
To protect your water supply you should carry out a risk assessment, monitoring, maintenance and treatment. You should also know your supply, including the source, pipe work and plumbing, and protect your supply at the source.
For details about changing to a mains supply, contact Yorkshire Water for advice.
More information can be found on the Drinking Water Inspectorate website.
