For relatively large projects within utility and industrial construction, different requirements and conditions apply to housing construction. GEP has developed special systems for such large projects; the so-called IRM ™ hybrid systems. With the hybrid rainwater system, rainwater is first pumped from the large tank to the system tank. From this system tank a pressure boost provides the tap points of water. There are also self-priming systems available, mostly equipped with double rainwater pumps, these should be relatively close to the rainwater well. You can also create a design of a rainwater system online via the online GEP rainwater calculation module.
