Strong Galvanised Steel Construction
Designed to support a considerable volume of stored water, this tank features corrugated steel panels that provide a strong and durable external structure.
The steel is approved to BS2989:1982 and galvanised using lead-free zinc to 275g/m² in accordance with EN10142.
The galvanised finish helps protect the steel against corrosion, making the tank well suited to long-term outdoor water storage across agricultural and commercial sites.
40% Structural Safety Margin
The tank incorporates a minimum 40% structural safety margin within its design, providing additional structural strength for demanding water storage applications.
This safety margin relates to the strength of the tank structure and does not increase the usable water capacity. The tank should not be filled beyond its specified maximum volume.
Durable Greenseal EPDM Liner
Inside the galvanised steel structure, water is contained using a flexible Greenseal EPDM liner.
The 0.75mm liner material offers excellent resistance to UV exposure, abrasion and cutting, making it suitable for outdoor water storage installations.
By separating the water containment liner from the external steel structure, the tank combines a flexible watertight layer with the strength of corrugated steel panels.
Agricultural and Horticultural Water Storage
Reliable access to stored water can be particularly important for agricultural and horticultural businesses during periods of increased demand.
This 100,000 litre tank provides substantial capacity for irrigation and general water management, helping farms, nurseries, garden centres and similar businesses maintain a large reserve of water on site.
It can be incorporated into a new water storage project or used to increase the capacity of an existing system.
Supplied in Kit Form
One of the advantages of a sectional steel tank is that it does not need to be transported to site as one enormous pre-assembled unit.
Instead, the tank is supplied in kit form for assembly at the installation location. This can make delivery and site access more practical, particularly where moving a large one-piece tank would be difficult.
A photographic instruction manual is provided to help with assembly. Correct site preparation and installation requirements should always be followed before constructing and filling the tank.
Suitable for a Wide Range of Applications
With a substantial 100,000 litre capacity, this tank can be incorporated into a variety of water storage and water management systems.
Typical applications include:
- Agricultural water storage
- Rainwater harvesting
- Water recycling
- Crop irrigation
- Horticultural irrigation
- Nurseries and garden centres
- Sports pitch irrigation
- Aquaculture
- Dust suppression
- Grey water storage
- Water attenuation
- Emergency water storage
