A private water supply is any water supply not provided by a licensed water company i.e. Severn Trent Water.

This can include water from wells, springs and boreholes.

The Private Water Supplies (England) Regulations 2016 ensures that water from private water supplies are safe for people to drink. Private water supplies have now been categorized into four types:

  • Large supplies – Supplies with commercial/public uses (e.g. hotels, restaurants, nursing homes, bed and breakfast or village halls) or large domestic supplies - i.e. those using more than 10m³/day or supplying more than 50 people a day on average.
  • Small Supplies – Supplies with two or more domestic premises but with no commercial premises. Usage less than10m³/day and fewer than 50 people a day supplied on average.
  • Supplies to single domestic property (where water is supplied only for domestic purposes)
  • Private Distribution Networks - The scope of the Regulations has now been broadened to include distribution networks, where water is further distributed beyond the responsibility of the licensed water company. Distribution networks may include water that is further distributed on caravan parks, large industrial estates or country estates or where water is further distributed by tanker.
