Water Quality

The main duty of this Council with regard to water quality is the routine sampling of Private Water Supplies within our area.

Private Water Supplies

Information on what private water supplies are and ways they are tested

What is a private water supply?

This is water supplied to homes and businesses that is not provided by a water company, such as South West Water.  Most private water supplies are in rural locations and are from wells, boreholes, springs or streams.  Approximately 1% of the population in England and Wales has a private water supply to their homes.  We keep a register of over 500 properties served by private water supplies in Torridge.

Safe drinking water is essential to good health - private water supplies are monitored because they may not be properly protected or treated and can become contaminated with bacteria and chemicals.

What are the implications of the Private Water Supplies Regulations 2016?

The Private Water Supplies Regulations 2016 cover all private water supplies and private distributions systems.  These supersede the Private Water Supplies Regulations 2009 and applies to water used for domestic purposes;  for example drinking, cooking, food preparation and washing, and also for water used for commercial purposes, such as hotels and restaurants.

Supplies are categorised into four groups:

  1. Single private dwellings that are owner occupied
  2. Small domestic supplies (more than one dwelling) supplying fewer than 50 people
  3. Private distribution systems where mains water is supplied to a person or business and then distributed by that person or business to other buildings, domiciles, draw-off points etc using private pipes or tanks - this can include caravan parks
  4. Large domestic supplies supplying over 50 people or serving commercial premises, including B&B's, holiday lets and residential tenancies

Risk assessments

The regulations require the council to carry out a risk assessment of private water supplies every five years (other than a supply that only serves a single dwelling - see below).  We take into account the source of the water, how it reaches the consumer and the number of people using it.  We also take into account whether the water is for domestic or commercial use, and in particular if it is used for food preparation.  The risk assessment involves surveying the supply to identify potential contamination, identifying possible prevention measures and treatment options. This risk assessment helps us decide how to monitor the supply and how often it should be monitored.

Sampling requirements

Water should be tested on a regular basis for a range of chemicals and micro-organisms that might cause an unpleasant taste or smell, or could affect the health of the person drinking it.  We also test for some substances which may not be harmful in themselves but could indicate that a more serious problem exists.

  1. Single private dwellings (owner occupied): Single private dwellings do not require routine monitoring or a risk assessment.  However, we recommend supplies are regularly checked and we can sample or risk assess at the owners request
  2. Small domestic supplies: The amount of monitoring required by the council will depend on the outcome of the risk assessment.  However, it will be a minimum of once every five years. Supplies will be sampled for basic parameters and anything else that arises from the risk assessment
  3. Private distribution systems: Monitoring must be carried out according to the outcome of the risk assessment
  4. Large supplies or commercial premises: The council will undertake sampling for a range of chemical, microbiology and metal parameters

The Council will make a charge to cover the cost of carrying out risk assessments and sampling and any other duties under these Regulations - see fees and charges http://www.torridge.gov.uk/article/12721/Financial-Services-Publications

Dairies

The Drinking Water Inspectorate (DWI) issued interim guidance in March 2011 for milking parlours served by a small private water supply (http://dwi.defra.gov.uk/stakeholders/guidance-and-codes-of-practice/pws-milk.pdf).  This recommends that at the present time local authorities do not need to carry out sampling or a risk assessment where a private water supply serves only a milking parlour, or a milking parlour and a single dwelling, providing there is no other commercial use, no other relevant food activity and no public activity or building.  Water sampling may be necessary to assure milk quality and safety and will be sampled on request.  The DWI will be reviewing this guidance.

What happens if the supply fails the required standard?

If a private water supply is tested and does not meet the standard, we may advise boiling water, or use bottled water until changes have been made to improve the water supply.  Please note, you should refer to the advice of the Food Standards Agency before giving bottled water to babies.

Recommended actions to improve the supply may include:

  • fencing off the area around a spring to prevent animals from causing contamination
  • creating an exclusion zone around a spring or a well so that fertilisers are not spread in the area
  • improving drainage around the source of the supply
  • replacing pipework

It may be necessary to install treatment to remove or lower the level of particular substances, for example:

  • ultra violet filters to destroy bacteria such as E.coli
  • acidity regulator
  • reverse Osmosis filters to remove aluminium or nitrates
  • iron and Manganese filters
  • filters to remove lead

Investigation

We may need to investigate the cause of sample failures that give rise to health concerns.  This can be substituted by a risk assessment being carried out.

Notices

If a supply is badly contaminated the Council might serve a formal Notice to prevent the water from being consumed until work has been carried out to improve the water quality to a required standard. Failure to comply with the notices may result in either works in default or prosecution in a Magistrates Court. Appeals can be made to the Magistrates Court or the Secretary of State depending on which notice is served.

Authorisations

We can serve an authorisation to allow failed supplies to continue whilst works are carried out to achieve compliance.  Authorisations may only be granted for failures that do not constitute a health risk (usually chemical parameters).  Before we issue one, we will consult all water users and the Health Authority and take their views into account. We will inform them of the authorisation and its conditions and provide advice to those that may be at greater risk, for example parents of babies.  We will review authorisations from time to time to ensure sufficient progress is being made towards improvement.

Who will be charged?

The council will apply a charge to any relevant person requesting a risk assessment, sampling or other activity - see fees and charges http://www.torridge.gov.uk/article/12721/Financial-Services-Publications

Otherwise fees are payable as specified in the invoice, by the relevant person as defined in section 80(7) of the Water Industry Act 1991.  This may be the owner or occupier of the property served by the supply, the owners and occupiers of the premises where the source is situated or any other person who exercises powers of management or control in relation to the source.

Where more than one person is liable the Council may divide the charge between them;  this may be the case for small domestic supplies where the owners share maintenance costs and do not pay anyone for supplying them with water.  This may depend on any agreement or other document shown to the local authority relating to the terms under which water is supplied.

Bathing & Recreational Water

The Environmental Protection Team of Torridge District Council issues results of sampling taken by the Environment Agency during the bathing season. These results are displayed at the access points to Westward Ho! beach and at Hartland Quay.

Environment Agency Sampling

Bathing water quality can be influenced by various sources that include discharges from sewage treatment works or outfalls around our coast and from agricultural run-off.  The EU Directive on Bathing Waters sets out water quality standards to protect the health of bathers.

Within Torridge District Council's area there are two EC Designated Bathing Beaches at Hartland Quay and Westward Ho!  Under Eu Directive 2066/7/EC, the Environment Agency takes 20 samples from Westward Ho! beach and 5 samples from Hartland Quay during the bathing season (between May and September each year).

Samples are tested for E.Coli and Intestinal Enterococci which are types of potentially harmful bacteria.

A classification for each 'bathing water' is calculated annually based on samples from the previous four years. These classifications are, from best to worst:

  • excellent - the cleanest bathing water
  • good - generally good water quality
  • sufficient - the water meets minimum standards
  • poor - the water has not met the new minimum standards. Work is planned to improve bathing waters not yet reaching sufficient

If water is classified as poor a sign will be displayed advising against bathing.

The thresholds for classifications of designated Coastal Bathing Waters are as follows:

Excellent      

95 percent of samples (or higher) contain no more than 250 E.coli (cfu/100ml) and no more than 100 Intestinal Enterococci (cfu/100ml)         

Good

95 percent of samples (or higher) contain no more than 500 E.coli (cfu/100ml) and no more than 200 Intestinal Enterococci (cfu/100ml)

Sufficient

90 percent of samples (or higher) contain no more than 500 E.coli (cfu/100ml) and no more than 185 Intestinal Enterococci (cfu/100ml)

Poor

means that the values are worse than the sufficient

Key

   cfu: Colony Forming Units

Seaside Awards are presented to resort/rural beaches that are well managed with excellent facilities, with mandatory water quality

Blue Flag resorts additionally have excellent water quality

For more information see https://www.keepbritaintidy.org/local-authorities/improve-public-spaces/blue-flag-and-seaside-award

Westward Ho! beach and Hartland Quay are consistently classified as excellent bathing waters.
