Private water supplies and distribution systems

Private distribution systems

A private distribution system is where a water company supplies water to the boundary of a premises and the person responsible for the premises supplies it to the occupiers of other buildings on the same site. This becomes a private water supply under the Private Water Supplies Regulations 2009.

Types of premises where this might occur would include:

  • Campsites where water is distributed to individual units or stand pipes
  • Business parks
  • Industrial estates
  • A college campus

Types of premises that are not included are as follows:

  • Blocks of residential flats/ apartments whether owner occupied or tenanted
  • Houses that have multiple occupancy
  • A row of two or more houses (usually a terrace) supplied by a water undertaker from a single common supply pipe

This further distribution of water is known as a 'private distribution system' and the regulations introduce responsibilities for the person in charge of the distribution.

The Drinking Water Inspectorate produces guidance on private distribution systems.
