Our WRAS Potable Water Tanks, otherwise known as drinking water tanks or vertical water storage tanks, come in a choice of 51 sizes ranging from 150 litres to 90,000 litres. These plastic tanks are constructed from food-grade polyethene ensuring durability and are finished with a smooth interior to protect against bacteria growth and allow easy cleaning.

All our potable tanks are WRAS (Water Regulations Advisory Scheme) approved and are available in black, boat blue or natural only.  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.

In some instances, these water tanks will have to be Fluid Category 5  to comply with the requirements of installation and use of cold water storage cisterns and sectional tanks connected to the public water supply (Water Fittings) Regulations 1999.
