Large Water Tanks


At Tricel, we specialise in GRP water storage tanks designed for new water tank projects or water tank replacements. Large water tanks are essential in ensuring a steady water supply for various purposes.

Our range of large water tanks vary in size, with sectional tanks used to hold up to 2 million litres of water. Sectional tanks are the best solution for storing large volumes of water for commercial or large-scale industrial applications. We offer bespoke tanks for customers looking for a unique water tank to meet their specific requirements.

Types of Large Water Tanks

There are three types of sectional tanks: externally flanged base tanks, internally flanged base tanks and totally internally flanged (TIF) tanks.

Externally Flanged Base – These are manufactured for areas without space restrictions and assembled on raised supports to give easy access to the connections below. The benefits of this large water tank include the option to fully drain the tank of water without the need for pumps, and it is also easier to maintain as all connections are accessible from the outside of the tank.

Internally Flanged Base – Large water tanks with an internally flanged base are designed for plant rooms with restricted headroom space and ideally built on a flat plinth or base levelling steels according to foundation requirements. Internally flanged base tanks cannot be fully drained without a pump. The tank is constructed and fastened from the inside, and the base needs to be level and able to support the cold water storage tank without movement. The fixtures are only available from the inside, allowing for extra headroom as access to base panels is not required.

Totally Internally Flanged (TIF) – A perfect solution for applications requiring maximum water capacity within a plantroom with limited space or access. They are designed specifically for the customer’s site and capacity requirements. TIF tanks have the same benefits as the IFB and EFB tanks, but they are installed from within the tank to make the most of the limited space inside the plantroom.

Large water tanks are versatile and cost-effective, and our GRP material is an environmentally friendly alternative. Whether you need them for residential, commercial or industrial purposes, these tanks offer reliability and peace of mind.
