One-piece GRP tanks
Available in a range of standard sizes, our one-piece tanks are supplied ready for installation. Suitable for plant rooms with adequate access and for most new-build applications.
Tank supply and integration
Specified for the application, not the other way round
Tank selection is not straightforward. Size, configuration, access constraints, whether the tank sits standalone or forms part of a packaged system, these all affect what is right for the project.
We supply tanks as part of our own packaged systems and as standalone products for integration into existing plant rooms. Because we also design and build the booster sets and packaged systems that sit alongside them, we can advise across the whole installation rather than just the tank in isolation.
Where access is restricted, our sectional GRP tanks can be assembled in situ. A practical solution for retrofit and refurbishment projects where single-piece tanks cannot be manoeuvred into position.


Cold water storage tanks are specified when a building needs reserve capacity beyond what the incoming mains can supply directly. They also provide protection for the mains water supply by incorporating backflow prevention devices, specified according to the fluid category risk within the application.
Commercial and residential developments with high peak demand. Buildings where mains pressure or flow rate is insufficient without storage. Plant rooms requiring a break tank to protect against backflow. Packaged booster systems requiring an integrated storage solution. Retrofit and refurbishment projects replacing ageing or non-compliant tanks.
GRP tanks in one-piece and sectional formats

Available in a range of standard sizes, our one-piece tanks are supplied ready for installation. Suitable for plant rooms with adequate access and for most new-build applications.

For plant rooms where access is restricted, our sectional tanks are assembled in situ. Available in horizontally split and internally flanged configurations, in sizes from small commercial to large industrial capacities.

Our break tank and booster set combinations mount on a shared stainless steel base frame. Designed as a complete cold water boosting solution, supplied tested and ready to connect.
