Commercial rainwater harvesting systems
We can supply you with a commercial rainwater harvesting system that is right for you and your business.
We use industry-leading components, that, with our service and maintenance package will ensure a long trouble-free service life.
Bespoke commercial systems
All of our commercial systems are made to your specific requirements.
To show how confident we are in our product, we offer a 3-year warranty against defective parts, on all of our commercial systems.
That’s three times the industry standard!
The only qualifying requirement for this is that we commission and service the system.
Commissioning and Service
We are proud to offer or services with experienced rainwater harvesting engineers.
How do they work.
Our commercial rainwater harvesting systems work by using the rainwater that has fallen on a rooftop. The rainwater is then piped, filtered, and stored in an above or below ground water storage tank(s).
When needed, the rainwater is then pumped directly to the point(s) of use (direct pressure system/suction system) or to the point of use via a header tank (gravity fed system).
Our systems are for non-potable use. In most cases, they are used to supply toilets, washing machines, and outdoor taps (for garden use).
The rainwater collection
During rainfall, rainwater that has fallen on the roof of your building is supplied by gravity to the storage tank via a pipe network and filter system. Rainwater passes through the integrated filter removing large particles, such as leaves, twigs, etc. before entering the tank.
From the storage tank and beyond
Once the rainwater is in the tank it is then pumped to the point of use with a submersible pump(s) situated in the tank which is controlled by one of three systems: direct pressure, in-direct pressure or boosted pressure system.
If there has been more rain than needed and the tank is at capacity, an overflow system is engaged and the excess water is piped by gravity to the storm drain via a one-way valve to prevent contamination in the tank.
Vice versa, if there hasn’t been much rainfall and your tank is running low then the control switch system is engaged and mains water is introduced into the tank, but only the minimum required. Thus leaving maximum capacity to receive the next rainfall.
These techniques keep your system running smoothly.
As well as the integrated filter, the overflow system also helps keep the rainwater and system clean by removing the scum layer (tiny particles, etc.) from the water surface in the tank.
These processes, along with a regular system service will keep the tank(s) and the entire system as healthy as possible and have your system running at optimal performance, always!
Controls for commercial rainwater harvesting systems are generally bespoke; designed and sized to reflect the demands of the building in which they are installed. There are however three specific types of rainwater harvesting system.
Combi Boosted Pressure Systems
Similar to the indirect system, but with the storage tank mounted at a lower level and then pumped to the point of use.
In-Direct Pressure systems
Rainwater is collected as with the direct pressure system, but the rainwater is pumped to a storage tank mounted at height (usually a roof space), from where it feeds by gravity to the point of use.
Direct Pressure Systems
On-demand water is supplied directly to the point of use by a submersible pump(s) under pressure.
