Heavy Duty Water Storage Tank - 10000 Litre
The largest water storage tank in the Heavy Duty range, built for sites that need serious industrial capacity or a genuine emergency water reserve. At 10000 litres, it holds double the capacity of the 5000 litre model in a 2490mm diameter footprint, moulded in one piece from UV stabilised HDPE for long term outdoor durability. The material carries WRAS approval, so the tank is rated for both potable and recycled water storage.
How this tank covers genuine industrial and emergency demand
Industrial sites and emergency water planning both need a reserve that won't run dry after a single day of heavy use. Smaller tanks force more frequent refilling, which isn't practical when water demand spikes or a refill delivery is delayed. At 10000 litres, this tank holds enough in reserve to cover sustained industrial use or an extended emergency period without relying on a same day top up.
Key Features
-
WRAS approved material: Independently verified as safe for potable water storage, not just general use
-
Largest capacity in the range: Holds double the water of the 5000 litre model in the same tank family
-
UV stabilised HDPE: Built for long term durability under permanent outdoor exposure
-
One piece moulded body: No seams or joints that could weaken under the weight of a full tank
-
Insert ready base: Can be fitted with a tap outlet or connecting pipework
-
Industrial and emergency ready: Suited to sustained industrial use and standby water reserves

Who is this for
This tank suits industrial operators needing a large standby reserve for process water, and facilities or commercial sites building genuine emergency water contingency into their site planning. Agricultural operations with heavy irrigation or livestock demand also use this size when smaller tanks mean refilling too often to be practical. It's the tank for sites where running dry isn't an acceptable risk.
Typical applications
-
Holding a large scale emergency water reserve for commercial or industrial sites.
-
Supplying sustained industrial process water where demand is too high for smaller tanks.
-
Storing bulk rainwater collected from large roof areas across a commercial or industrial site.
-
Holding WRAS approved potable water as a substantial backup supply.
-
Storing recycled water for wash down, dust suppression or non drinking industrial use.
-
Providing an irrigation or livestock water reserve for large agricultural operations.
How to use
Step 1: Position the tank on firm, level ground capable of bearing the weight of a full tank, roughly 10 tonnes at 10000 litres.
Step 2: Fit a tap outlet or connecting pipework insert at the base for industrial, irrigation or general use.
Step 3: Connect the inlet to a rainwater diverter or mains fill point, depending on the water source.
Step 4: Check the lid is fully seated before use to keep out debris and prevent algae growth.
Step 5: Inspect the tank periodically for cracking, discolouration or leaks after long UV exposure.
Common mistakes
-
Installing on ground that isn't level or genuinely load bearing, which becomes a serious risk once the tank is full.
-
Leaving the lid loose or missing, which lets in debris, insects and sunlight that encourages algae.
-
Fitting a tap or pipework insert without following the correct method, which can compromise the seal.
-
Assuming the tank is rated for burial and installing it below ground, which it is not built for.
-
Underestimating actual industrial or emergency demand and undersizing the tank for real usage.
Safety
This tank is designed for above ground installation only and is not rated for burial or below ground use. A full 10000 litre tank weighs approximately 10 tonnes, so the ground must be firm, level and genuinely capable of bearing that load without settling. It is not suitable for storing chemicals, fuel or any liquid outside its intended water storage use, and the lid should stay fitted at all times to prevent contamination.
Maintenance
Rinse the interior periodically to remove sediment and prevent algae build up, especially where the tank collects rainwater. Check the lid seal, tap outlet and any fitted pipework for wear every few months. Keep the surrounding area clear of overhanging vegetation and confirm the ground hasn't shifted or settled under the tank's substantial weight.
Frequently Asked Questions
Q: Is this tank approved for storing drinking water?
A: Yes. The material used in this tank carries WRAS approval, confirming it meets UK water quality standards for water it comes into contact with. That makes it suitable for potable water storage as well as recycled water, industrial and general site use.
Q: What does WRAS approval actually mean?
A: WRAS stands for the Water Regulations Advisory Scheme, the body responsible for assessing materials and fittings against UK water supply regulations. A WRAS approved material has been independently tested to confirm it won't contaminate water it holds, covering factors like taste, odour and chemical safety. For a tank of this scale doubling as a drinking water reserve, that verification carries real weight.
Q: What is this tank not suitable for?
A: It's designed for above ground installation only and is not rated for burial or underground use. It should not be used to store chemicals, fuel or any liquid other than water. It is also not designed for direct connection to a pressurised mains water system.
Q: Why choose this over the 8000 litre model?
A: The 10000 litre tank adds a further 2000 litres of capacity in the same 2490mm diameter footprint as the 8000 litre model, with the extra volume built into height rather than floor space. For industrial sites or emergency reserve planning where downtime from running dry isn't an option, that extra margin matters more than the small difference in footprint. It's the largest capacity available in the Heavy Duty range.
Q: Does the ground need any preparation before installing a tank this size?
A: Yes, more so than with the smaller Heavy Duty tanks. A full 10000 litre tank weighs around 10 tonnes, so the ground must be firm, level and genuinely capable of bearing that load without settling. Given the scale involved, it's worth having ground conditions checked before delivery, particularly on sites with soft, made up or previously disturbed ground.
Q: How long will the tank last outdoors?
A: The UV stabilised HDPE construction is built for permanent outdoor exposure, and the one piece moulded body adds resistance to cracking under the sustained weight of a full tank. Keeping the lid fitted, avoiding overfilling and checking periodically for damage all help extend its working life. Given the scale of this tank, ground conditions play an even bigger role in its long term performance than with smaller models.
