The flat, fertile land north and east of the city is some of the most intensively cropped in the North West. Growers there store water for irrigation, and a steel tank fed from roof runoff or a borehole gives large, accessible storage next to the packhouse without digging a reservoir.
On mossland, where the peat is soft and the water table high, keeping the storage above ground also keeps it away from the wettest ground on the holding.
Along the Mersey, sites have their own reasons. Logistics sheds at Knowsley, Speke and the port have acres of roof that can be harvested for toilet flushing or washing vehicles. Manufacturing and chemical plants at Widnes and Runcorn use stored process or recycled water. Depots need wash-down supply.
On low-lying, filled land near the river, a tank on a slab also avoids an excavation that would hit groundwater or contaminated spoil.
- Irrigation for growers
- Harvested roof water
- Process and recycled water
- Wash-down for yards
A separate contractor provides the foundation, able to take the tank at its fullest. Our setting-out check on that foundation, for level and line, comes ahead of any steelwork.
The galvanised sheets bolt into rings, and rings stack until the shell is tall enough for the volume. The steel gives shape and strength; a tailored liner hung inside is what actually keeps the water in. We fit inlets, outlets, overflow and level indication and seal them through the liner. The first fill is done in stages, with a pause at each level to look over seals and shell before the tank is put to work.
Once the base is ready, a tank usually goes from first panel to commissioning in days rather than weeks. For a grower waiting on a dry season or a plant working to a shutdown, that is often what decides it.
Galvanising protects the steel, but salt-laden air near the Mersey and the Sefton coast is harder on any metal than inland air. If your tank will stand close to the shore, tell us at the start so the panel and fitting specification can take the exposure into account.
To quote properly we ask for the volume, the intended use, a plan of the space with the access route marked, and what will feed and draw from the tank. A grower will usually know the pump and the borehole or roof it connects to; an industrial user may have a process engineer setting flow rates. We fit the connections they specify and leave the controls and pumping to the people who designed them.
If the base hasn't been built yet, we'll send its requirements so your contractor builds it once and builds it right.
