Private Water Supplies

If the source of your water supply is not provided by a water company (for example United Utilities), then it is not considered to be a ‘mains’ supply.  In this case you have a private water supply.

A private water supply can be obtained from a variety of sources including springs, wells, boreholes, rivers, streams, lakes, ponds or water harvesting for example, and this supply may serve a single property, several properties or commercial premises.

It is essential that private water supplies are maintained in order to minimise any risk to health and that they have the same quality standards as the mains water supply.  Cheshire East Council has a duty to check the quality of all water supplies within our area and The Private Water Supplies (England) (Amendment) Regulations 2018 require us to risk assess, sample and analyse the water from these supplies.

The Regulations affect all private supplies although those serving a single dwelling will only be risk assessed and sampled upon request, unless these are newly installed supplies.

There is a fee for this service.

What is needed?

Sampling frequency:

  • Commercial/large domestic/rental supply (Regulation 9) - at least once a year
  • Shared domestic supply (Regulation 10) - at least every 5 years
  • Farm assurance testing (microbiological only) - as requested
  • Single domestic property - as requested
  • New supply or brought back into use after over a year - As soon as practically possible 

Risk Assessment frequency:

  • Commercial/large domestic/rental supply (Regulation 9) - every 5 years
  • Shared domestic supply (Regulation 10) - every 5 years
  • Farm assurance testing (microbiological only) - N/A
  • Single domestic property - N/A unless a sample is requested, then this is required prior to the sample being taken
  • New supply or brought back into use after over a year - As soon as practically possible

Risk Assessment

A risk assessment involves looking at the source of the supply, the surrounding area and anticipating what might lead to contamination.

Sampling 

One of our officers will take the sample from a tap used to supply water for drinking or cooking.  In food premises it will be taken from the point immediately before the supply is used for food preparation.  We will have the water analysed for both chemical and microbiological parameters, depending on the risk assessment and upon the Legislation.

Usually, water samples will be analysed for a selection of metals, inorganic and organic parameters and microbiological contaminants.  Sometimes, if supplies have a potential risk of contamination from radioactive sources (from geology or from man made contamination), then samples will be analysed for radioactive substances.

The results of the sampling will be forwarded to you with a letter, usually within 28 days of receiving them from the laboratory.  The letter will explain the results and inform you if any remedial action is required to safeguard your supply.
