Rainwater Harvesting Specification Tool

You asked for a standard rainwater harvesting specification to add to your documents.... Stormsaver have given you better than that!

We have created a unique, online specification tool for consultants, public health engineers and architects. Or if you are a contractor working on a Design and Build Project, our clever programme can build you a bespoke specification in just 3 minutes. 

Once you have completed the information we need to be able to size the system, our unique sizing system will provide you with the correct specification for your needs, complete with tank capacities, the correct controls and pumping requirements, data sheets and written documents for you to include in your specification.

Not only will you save HOURS of time, you will have the peace of mind that, provided the information inputted is correct, then your specification should be correct.

Once completed, our team will recieve a copy of the specification you have created and we would always advise you to call to run through this with us as each building has it's own needs.

Our Rainwater Harvesting Specification Tool can be accessed HERE.

Give it a try today and let us know how you get on. If you have any feedback it is always welcome.


“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”
