“We installed the Stormsaver domestic rainwater harvesting system 8 years ago. The savings on our mains water consumption have been amazing. We are a 4 person household, with 2 kids so lots of baths and clothes washing! We use around 56m3 of mains water a year the same as an average single person household without rainwater harvesting.  Our systems provides rainwater for toilets, laundry and irrigation and has reduced our water bill over £200 a year. I specialise in designing and building low energy housing and it is important that I not only research the best available products, but actual experience using them. The Stormsaver system has been simple to install and maintain with very good after market care, I will be using their product again.”
