Freerain domestic and commercial rainwater harvesting (RWH) systems have been in production since the year 2000, with thousands of systems now in-service.

In 2014, Freerain became a brand owned by manufacturing company Rototek Ltd, with technical support to customers outsourced to Ecoserve; a pre-sales and post-sales advice service is provided by Rototek.

The purpose of this site is to provide prospective purchasers of Freerain domestic systems with the product knowledge needed to order the system best-suited to their needs, and to help existing users to get the best from their systems.

Commercial RWH systems operate on similar principles to domestic systems, but are usually bespoke to a project; commercial system users needing support are advised to Contact Us.
