Commercial Potable Water Tanks

Storing drinking water on a commercial site means meeting strict standards without cutting corners on capacity or hygiene. Our commercial potable water tanks give you safe, compliant storage built around your site, using WRAS-approved liner materials and a build quality that lasts for decades. Whether you run a factory, a hospital, or a food production facility, you get water storage you can rely on.

Why Commercial Potable Water Tanks Need the Right Materials 

Potable water storage is only as safe as the materials holding it. We line our tanks with a special grade of butyl rubber tested to BS6920 and approved under the UK Water Regulations Advisory Scheme, so stored water stays safe to drink. The liner resists chlorine and other treatment chemicals, which keeps sterilisation simple and your supply clean. It uses no additives or plasticisers, so it will not taint the water or break down over time. 

How Our Potable Water Storage Tanks Keep Water Safe 

Our site-assembled cylindrical water tanks are engineered to hold potable water cleanly and reliably. The butyl rubber liner forms a completely impermeable seal that blocks any transfer of liquid or vapour, and it stays flexible across a wide temperature range. That means dependable performance whether the tank sits in a plant room or outdoors in changing weather. The liner also handles minor ground movement without losing its seal, which protects the stored water for the long term. 

Sizing a Commercial Potable Water Tank for Your Site 

Every site has different demand, so we build to capacity rather than to a fixed catalogue size. From compact units for smaller premises to large water tanks for high-demand operations, we design each one around your daily usage and the space you have. Hospitals, manufacturing plants, and food and drink sites all draw water differently, and the right tank reflects that. If you need extra head room for peak periods, we factor it in from the start. 

Choosing Between Galvanised Steel and Aluminium 

Both hot-dip galvanised steel and marine-grade aluminium make strong, long-lasting potable water tanks, and the right choice depends on your environment. Galvanised steel water tanks offer proven durability and value, while aluminium suits sites where weight or corrosion resistance matters more. We help you weigh the options, so the tank fits the job rather than forcing the job to fit the tank. 

Keeping Your Potable Water Storage Tank Compliant 

Compliance does not stop at installation. Regular inspection and upkeep keep your potable water storage tank performing and your site meeting its obligations. If a liner is ever damaged, our tank refurbishment services restore it quickly with minimal disruption, and we supply cold repair kits for remote or overseas installations. Staying on top of maintenance also protects the warranty and extends the working life of the tank.
