Above Ground Water Tanks

Our above ground water tanks are designed for safe, durable water storage across domestic, agricultural and commercial applications. Ideal for properties where underground installation isn’t required, these tanks provide a practical and cost-effective solution for bulk water storage.

We supply both potable (drinking water safe) and non-potable water tanks in a wide range of capacities, from smaller domestic systems through to large agricultural and industrial storage tanks. Manufactured from high-quality, UV stabilised polyethylene, our plastic above ground tanks are corrosion-resistant, low maintenance and built for long service life. Read More

Common uses include rainwater harvesting, farm and livestock supply, irrigation systems, construction sites and general water reserve storage.

Need help choosing the right size or outlet configuration? Our team can advise on capacity, fittings and delivery options across the UK.

Yes, provided you choose a potable (drinking water safe) tank. Potable tanks are manufactured from WRAS-approved or food-grade materials and are designed specifically for storing clean drinking water.

The correct size depends on your application. Domestic properties typically require 900–2000 litres, while agricultural and commercial users often require 3000 litres or more. Larger capacity tanks are available for bulk storage.

Yes. Tanks must be installed on a level, solid and load-bearing base such as concrete or compacted hardcore. A stable base ensures safe operation and prevents distortion or stress damage.

High-quality polyethylene tanks are UV stabilised and corrosion-resistant. With proper installation and maintenance, they can last 15–25 years or more.
