RainHarvesting Ireland offers many systems for both domestic use and for larger schemes such as schools, offices, industrial and agricultural buildings.
All our systems are fully automatic so the pump only runs when water is called for and the system switches back to the mains water when there is insufficient rainwater.All systems may have a mains water connection and most systems require an AC mains supply. Alternatively our 12 volt Rainharvesting system is designed to run off wind or solar energy. The choice of a particular system will depend on your application and budget. How does it work?
There are a number of different rainwater harvesting systems available, but a typical example would be rain collected from the roof travelling via a drainpipe into a storage tank (usually underground) once the leaves and debris have been filtered out. The water can be used to supply toilets, outside taps etc. through a separate pipe network. A control unit monitors the water level in the storage tank and can display this information to the user. If levels drop too low, the system switches to the mains water supply and if it gets too high, an overflow trap allows floating material to be skimmed off to a storm drain. Reduced water usage has environmental benefits and while rainwater harvesting has the potential of significant financial savings, this depends heavily on a number of factors: - The water supply being metered.
- The size of the surface area that the water is being collected from.
- Whether or not the reduction in metered water will translate to a reduction in the wastewater charge (as Water Company policy varies across the country).
Larger projects such as housing developments, industry and agriculture will have a much shorter payback time than single domestic dwellings and savings could run into many thousands of Euros.
