It is simply a method of collecting rainwater from a buildings’ roof (via the normal drainage system), filtering and storing it for re-use, in order to reduce the amount of water used from the mains supply, and to reduce the amount of stormwater run-off.
It is important to understand the difference between the options when choosing a system for harvesting rainwater for your project.
With water prices rising and the continually increasing demand for water consumption, more and more businesses are realising the benefits of harvesting rainwater. There is also a growing desire and consumer demand for companies to operate more sustainably and to reduce their impact upon our environment.
Rainwater harvesting offers not only a solution to reducing demands on water supplies, but can also give significant financial benefits, in some cases saving £1000’s year on year. With many new commercial buildings being constructed to meet the requirements of BREEAM, rainwater harvesting is becoming increasingly commonplace and is now a well tried and tested technology.
Rainwater harvesting systems for commercial and industrial buildings are generally bigger, more sophisticated versions of those used for domestic situations.
