OASIS Rainwater Harvesting systems are unique with a 30 year tank warranty. Dissatisfied with the sectional German domestic rainwater harvesting systems that we used to supply, we have designed one SIMPLE, RELIABLE and AFFORDABLE rainwater harvesting system for both domestic and commercial properties. Our tanks are a leak-proof ONE PIECE construction, made in Yorkshire, with no complex on-site assembly of a 2 piece tank.

Unlike most other rainwater harvester manufacturers, we make only ONE rainwater harvesting system that can be used for ALL purposes, both garden and in the home. There is no need to wade through pages of complicated pump, filter and syphon options and prices - all you need to choose is the size of the rainwater storage tank.

Why make rain harvesters complicated?
