Insulated, suitable for storage of wholesome water (potable water).
Un-insulated for storing of water for non-wholesome applications such as process water for factories, rain water harvesting.
All panels are fabricated to withstand harsh climatic conditions.

2. Bolts
Tanks are assembled using 316 grade S/S bolts internally and galvanised bolts externally, complying with current British Standards
BSEN 13280:2001. If required, grade 316 S/S bolts may be placed throughout the tank.

3. Access hatch
An access hatch is supplied as standard for tank maintenance and access.

4. Screened vent
We provide a screened vent with all tanks for ventilation.
Additional components

5. Raised ball valve housing
Permits the ball valve to be mounted at a higher level on the tank, therefore increasing the usable volume of water.

6. Tank division
All buildings requiring un-interrupted water supply should install a divider in the tank. The divider allows one side of the tank to be drained down for maintenance, while water supply is maintained from the second segment of the tank.

7. Ladders
Where the tank height is greater than 1.5m, an internal and external ladder is recommended.

8. Condensation trays
Available for every size tank if required. Condensation trays are supplied in sections and bonded into a single unit on site. A condensation tray can only be supplied with tanks that have an internally flanged base.

9. Connections
Our sales team will discuss various options available.

10. Side access hatch
A side access hatch is beneficial where height restrictions apply. It also permits access, if in the event of personnel getting into difficulties inside the tank, while carrying out maintenance work.
