What sizes of polyethylene water storage tanks do you offer in this collection?

This collection covers tanks from 75 litres up to 1000 litres, with several intermediate sizes available. This range is designed to suit everything from small top-up header tanks to medium-capacity storage for commercial and industrial applications.

What are polyethylene water storage tanks used for?

These tanks are commonly used for potable and non-potable water storage, header tanks in heating systems, rainwater harvesting, and general process water holding. They're widely specified across construction sites, manufacturing facilities, utilities infrastructure, and mechanical services installations.

Are these tanks suitable for storing drinking water?

Many of the tanks in this collection are manufactured to WRAS (Water Regulations Advisory Scheme) approved standards, making them suitable for potable water storage. Always check the individual product listing to confirm WRAS approval for the specific tank you need.

What material are these tanks made from and why?

All tanks in this range are rotationally moulded from medium-density polyethylene (MDPE). This material is lightweight, corrosion-resistant, UV-stabilised, and extremely durable, making it ideal for long-term water storage in both indoor and outdoor environments.

Can these tanks be installed outdoors?

Yes. Polyethylene tanks in this collection are UV-stabilised to resist degradation from sunlight. For best performance and longevity, we recommend placing the tank on a flat, solid base and, where possible, shielding it from prolonged direct sun exposure.

Do you offer stage payment options on larger orders?

Yes, stage payment options are available. This is particularly useful for contractors and procurement teams managing project budgets. Get in touch with our sales team to discuss a payment arrangement that works for your order.

What fittings and connections are included with these tanks?

Included fittings vary by model, so check the individual product description for full details. Many tanks come with pre-fitted inlet and outlet connections, and we stock a comprehensive range of compatible fittings, valves, and pipework if you need additional connections.

How do I choose the right tank size for my application?

Start by calculating your required storage volume based on daily usage, flow rates, and any buffer capacity you need. Consider the physical space available as well, including height restrictions and access for installation. Our technical team can help you match a tank to your specific requirements if you're unsure.

Are these tanks compliant with UK building and water regulations?

Tanks in this collection are manufactured to meet relevant UK standards, and many carry WRAS approval for potable water use. We work with trusted manufacturers who maintain strict quality controls.
