“We have been involved in the specification and installation of Stormsaver rainwater harvesting systems now for over 10 years. Our very first experience of rainwater recovery was with the company and I remember Michael himself setting up and commissioning this system on site. What impressed me most even all those years ago was the company’s attention to detail, enthusiasm and professionalism and this has continued as the company has grown to what it is today.  We have no hesitation in saying our first call when it comes to rainwater recovery will be to Stormsaver, their prompt reaction, competitiveness and quality of equipment is second to none and they will always try to have the system fully commissioned when they leave the site.  We hope they continue the great work they have already done and we look forward to many more successful years working together to save even more water”
