Potable vs Non-Potable Water Storage Solutions
Tricel one piece tanks also known as cistern tanks are fully certified for the use of potable water. Our WRAS Approved GRP water tanks ensure you meet your health and safety obligations.
In order to fulfil health and safety directives, which states water, that is to be or may be consumed by humans, must be held in Insulated tanks, and that all potable water tanks must meet the following criteria.
Potable water tank specifications:
- Factory insulated with CFC Free Foam on all sides (25mm standard insulation)
- Manufactured from Fibreglass
- Lids must be sealed and insulated
- Potable water tanks must have screened inlet and overflows
- Tanks must be insulated to reduce the risk of freezing in winter and for temperature control during the summer.
