Our CAT 5 Potable Water Tanks are designed to provide maximum protection against backflow contamination while ensuring safe, reliable drinking water storage. Featuring a Type AB Airgap Break System, these tanks create a secure separation between your mains water supply and stored water, offering backflow prevention that meets Category 5 compliance.

Ideal for agricultural, commercial, and industrial applications, our CAT 5 tanks ensure water safety in environments where there’s a risk of contamination. With their screened weir overflow system, they prevent water from siphoning back into the mains, fully complying with Water Supply (Water Fittings) Regulations 1999 and Scottish Water Byelaws 2004.
