Rainwater Harvesting

A rainwater harvesting system collects, filters and stores rainwater.

When rain falls onto the roof of a property, it’s channelled through the gutters and downpipes into a rainwater tank via a filter.

The filter allows rainwater to be cleaned before it passes through to the tank – preventing leaves, moss or debris from entering the tank. 

The water within the system is then stored reliably in the rainwater storage tank until it can be diverted to the required place. This could be an outdoor tap for garden irrigation or car washing, to a washing machine or a toilet for flushing.

Our rainwater harvesting systems are designed to accommodate the needs of domestic, commercial and industrial customers, including (but not limited to) farmers, homeowners, gardeners and landlords.

Our tanks

Our high-quality rainwater tanks are made from plastic HDPE or galvanised steel. You’ll also discover a choice of sizes, ranging from 150 Litres, all the way up to 768,000 Litres, or more if required.

We aim to satisfy the demands of all industries and buildings, hence why we provide the Gravistore 1 Building (agricultural and commercial rainwater harvesting solution for premises with one building), as well as the Premistore (2+ Buildings)! These boast a long-life design and are manufactured to meet British safety standards.

The most popular rainwater harvesting tanks include the 5,000 Litre, 10,000 Litre, 15,000 Litre and 30,000 Litre which are available in various options at Cotterill Civils. Some of the rainwater harvesting tanks are horizontal, whilst others are bunded, static or vertical. We also have cone tanks available that are designed specifically to collect and use water automatically.
