Below you'll find answers to the most common questions we receive about our range of 1200 to 6000 litre polyethylene water storage tanks. If you need further guidance, our technical team is always happy to help you find the right solution.

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

This collection covers tanks from 1,200 litres up to 6,000 litres, giving you a broad range of capacities suited to commercial, industrial, and agricultural applications. If you need a size outside this range, get in touch and we can advise on alternatives from our wider product catalogue.

What are polyethylene water storage tanks made from, and why is that material used?

These tanks are manufactured from medium- or high-density polyethylene (MDPE/HDPE), a robust and lightweight thermoplastic. Polyethylene is highly resistant to corrosion, UV degradation, and a wide range of chemicals, making it an excellent long-term choice for storing potable and non-potable water.

Are these tanks suitable for storing drinking water?

Many of the tanks in this collection are approved for potable (drinking) water storage and comply with relevant WRAS (Water Regulations Advisory Scheme) requirements. Always check the individual product listing for confirmation of potable water suitability before ordering.

Can I install these tanks outdoors?

Yes, polyethylene tanks are well suited to outdoor installation. The material is UV-stabilised to withstand prolonged sun exposure, and the tanks are designed to cope with typical UK weather conditions. For best performance, we recommend placing the tank on a solid, level base such as a concrete plinth.

How much does delivery cost, and how quickly will my tank arrive?

We offer a flat-rate delivery charge of £12 across all orders, regardless of size, delivered nationwide across the UK. Delivery times vary depending on stock availability, but we prioritise fast, dependable dispatch. If your project is time-sensitive, contact us and we'll confirm an expected delivery date before you place your order.

Do you offer stage payment options for larger orders?

Yes, we understand that larger purchases can represent a significant outlay, so we offer stage payment options on qualifying orders. Please speak to our sales team to discuss a payment schedule that works for your project budget and timeline.

What fittings and connections are included with the tanks?

Standard fittings vary by manufacturer and model, so we recommend checking the individual product page for a full specification. If you need additional outlets, overflows, or inlet connections, our team can advise on compatible fittings and supply them alongside your tank order.

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

The right capacity depends on your daily water demand, available space, and any regulatory requirements for your site. As a general guide, consider peak usage periods and whether you need reserve capacity for emergencies or fire suppression. Our technical team can help you calculate the correct size if you provide details of your application.

Are these tanks compliant with UK building and water regulations?

The tanks we supply are manufactured to meet relevant UK standards, and many carry WRAS approval for potable water use. Compliance with local building regulations, including byelaw 30 kits where required, should be confirmed with your installer or local water authority. We can supply any additional compliance accessories you may need.

Can I use these tanks for rainwater harvesting?

Absolutely. Polyethylene tanks in this size range are a popular choice for rainwater harvesting systems in commercial and industrial settings. You'll need to ensure the tank is fitted with appropriate inlet filters, overflow connections, and a pump system. We can supply compatible ancillaries to complete your setup.

What maintenance do polyethylene water storage tanks require?

Polyethylene tanks are low-maintenance by nature. We recommend periodic inspections of fittings, seals, and the tank body for any signs of wear or damage. For potable water tanks, regular cleaning and disinfection in line with your site's water hygiene policy is advisable to maintain water quality.
