Rain Water Harvesting Systems
The tri-cel rain harvesting system is a simple solution for taking "free" rainwater off the roof on commercial or domestic buildings and reusing this water to flush toilets or as process water in factories etc. As water metering becomes more prevalent in Europe, using free Rainwater is an easy cost saving solution available to all. Our simple system uses a tank (underground or overground) and a control centre. Almost any capacity in a single tank is available. A pressure controlled pump feeds the rainwater through a special pipework system to the building. If there is insufficient rainwater, only the required amount of water is drawn from the mains water supply, however the system always favours the rain-harvesting tank. Once more rainwater becomes available, the system comes back online and the mains water is automatically shut off.
"Clean Water"
The rainwater is filtered from the roof using a Tri-Cel VF volume filter (roof sizes up to 350m2 (larger filters available up to 3,000m2). Multiple filters may be required for different down pipes. Upto 90% is the water is available for reusing as harvested rainwater.
Overground systems are suitable for ground level or in a basement, reducing the costs of underground excavations & installation and are suitable for existing buildings. Our experienced site crews will assemble the tank and commission the system on site, all you have to do is plumb to the building.
Underground systems, only a manhole and small control cabinet are visible after installation. Again we commission the system on site.
Rainwater is collected from the gutters and passed through a filtering device to remove debris and stored in either an underground or over-ground tank. The filtering basket manufactured from stainless steel, filters leaves, moss and other debris, and dirt is directly flushed away from the holding tank into the drainage system. It can be easily removed and cleaned and requires no repalcement parts.
The rainwater enters the tank via a calmed inlet to avoid sediments being stirred up from the base of the tank.
The water is removed from the tank when required by a floating suction filter and pumped to the point of use. This ensures that the water is taking from the cleanest part of the tank at all times. In the event of water depletion in the unit, a three-way valve will automatically switch to the mains-water supply.
A Siphon overflow is supplied with the Rainwater harvesting system to remove excess rainwater when the unit is full. This also removes any particles floating on the water surface. This mechanism ensures that the water remains fresh within the tank.
The rain harvesting systems is available for domestic and commercial applications.
