The installation and use of cold water storage cisterns and sectional tanks connected to the public water supply must comply with Water Supply (Water Fittings) Regulations 1999 in England and Wales and the technically identical Scottish Water Byelaws. In order to meet these requirements Fluid Category 5 Break Tanks must be used in this instance. These plastic tanks are currently available in 14 sizes from 300 litres up to 40,000 litres in Vertical and Horizontal options, with an additional option of an insulated jacket fitted at time of manufacture; other sizes are available on request.
Our water tanks are all fully DWI approved and meet the specific requirements of Regulation 31.
The Drinking Water Inspectorate (DWI) under the umbrella of the UK Government’s DEFRA (Department for Environmental, Food and Rural Affairs) states that; “Protection of public health of consumers through safeguarding the quality of drinking water is a key aspect of the drinking water quality regulatory framework” Regulation 31 ensures that water suppliers, when producing and distributing drinking water, only use products and substances that do not cause any detrimental effects on the safety or quality of the drinking water.
