The only Rainwater Harvesting System supplier you will ever need


All of Stormsaver’s rainwater harvesting systems fully comply with:

BS8515: Rainwater Harvesting Systems 2009

Water Regulations Advisory Service (WRAS) guidelines
Water Supply (Water Fittings) Regulations 1999
Building Regulations

Plus all other relevant health and safety guidelines, including the protection of mains water drinking supplies against potential cross contamination


Building Services Research Information Association
Stormsaver follows the best practice guidelines set out by the Building Services Research Information Association (BSRIA) and the Construction Industry Research Information Association (CIRIA).

British Standard
All Stormsaver systems not only meet the British Standard for rainwater harvesting, they exceed it in many areas.

As market leaders were committed to maintaining our position, so we ensure that we surpass building regulations wherever possible.

Weve even produced our own guide to the latest British Standard to effect rainwater harvesting - BS8515:2009. Its available to download here.


The installation of a Stormsaver system can help you gain points for the Building Research Establishment Environmental Assessment Method (BREEAM), win Eco Awards, Green Building Awards and many other local accreditation schemes.


Enhanced Capital Allowance
The Stormsaver product range is accredited by the Department of the Environment, Food and Rural Affairs (DEFRA) under HM Revenue & Customs Enhanced Capital Allowance scheme and follows the best practice guidelines set out in the scheme.

Building Regulations
Part G of the regulations sets out minimum water efficiency requirements in new buildings to meet sustainability targets through saving water. Suggestions for use of rainwater harvesting systems are included within Part G.

Sustainable Urban Drainage
To help mitigate localised flooding, water authorities are placing restrictions on any new water being directed to storm drains. Therefore, the Stormsaver system has a central part to play in Sustainable Urban Development Schemes (SUDS). The installation of a Stormsaver system can, where used appropriately, minimise surface water run-off to help reduce the danger of localised flooding. More importantly, a Stormsaver system can, where appropriately sized, help the user to recycle the water that would otherwise have been lost.

‘Stormsaver have always provided a quick response to any queries and their customer service is superb’
