We design and manufacture a wide range of rainwater harvesting equipment and supply products at competitive prices with fast delivery. Our large 60,000 sq ft warehouse in Peterborough allows us to hold extensive stock, ensuring quick dispatch across the UK and internationally.

We stock everything required for a rainwater harvesting project, including rainwater tanks, filters, pumps, rainwater management systems, underground pipework and the labels required by most water authorities.

Complete Rainwater Harvesting Systems
We specialise in providing complete rainwater harvesting solutions for a wide range of projects. These range from single residential properties to large multi-house developments.
Over the years, we have worked with many national housebuilders and housing associations. Our experienced team can provide expert advice on the correct tank size and system design. We can also assist with installation guidance and Sustainability Code credit assessments.
Innovation in Rainwater Harvesting
At Rainwater Harvesting Limited, we are committed to developing innovative products for the industry.
We manufacture the Rain Director®, the only NSF Reg4 approved header tank solution designed to control the flow of both rainwater and mains water within a property. This system is widely regarded as one of the most energy-efficient rainwater harvesting solutions available.
We also manufacture the Rain Backup® in a Box, an NSF Reg4 approved mains water backup system. This simple but effective solution ensures your tank always maintains a water supply for appliances and amenities connected to the rainwater system.
Our Pump Technology
Our sister company, HydroForce™ Pumps Ltd, manufactures the HydroForce™ Series 4 Clean Water Pump. This gives us a significant advantage in the market, as we have full control over the key moving components within a rainwater harvesting system.
Technical Support and Customer Care
We pride ourselves on providing excellent customer service. Our dedicated after-sales support team and experienced technical department are available to assist customers throughout the installation process and beyond.
