A private water supply is defined as any water supply which is not provided by a water company. The source of supply may be a spring, borehole, well, stream, river, lake or from land drains.
There are approximately 1200 commercial premises and domestic properties in Denbighshire served by a private water supply. Good quality water is very important to everyday life. Every commercial premise or house must have a sufficient supply of wholesome water for it to be fit for people to use water in, etc or to live in.
Water is at risk of being contaminated from everything that it comes into contact with.
There are new revised regulations - Private Water Supplies (Wales) Regulations 2010. Links to information are attached.
To protect public health, the government has set legal quality standards which all water used for commercial food and drink production and for domestic purposes, must meet. Local authorities have the responsibility to ensure that private water supplies are wholesome and sufficient and this is achieved by programmed monitoring and risk assessment and by inspection, sampling and analyses. The frequency is dependent upon supply classification.
Supplies are classified into three categories, depending on the use of the supply, whether for public use or domestic household use (domestic use includes farm use, apart from a dairy farm) and on the volume use, at greater than or less than 10 cubic metres per day.
There are fees and these are at various levels depending on the use of the supply.
Large and Small private water supplies:
Private water supplies at commercial premises eg hotels, restaurants, cafés, residential homes, dairies, bed & breakfast, self catering, caravan and camping sites, bottled water, etc.
These are tested at least once per annum, depending on the number of people using water from the supply and the amount of water used.
Large, Small and Single private water supplies:
Private water supplies at domestic properties.
These are classified depending on the number of properties supplied and the volume used.
Large - greater than 10 cubic metres per day serving more than one property - at least once per annum.
Small - less than 10 cubic metres per day serving more than one property - at least once every 5 years.
Single - serving one property - in the programme - at least once every 5 years.
