Rain Water Harvesting, Design & Install
Download our Information sheet
Rain water harvesting utilises the naturally occurring rainfall, by using existing roof surfaces as a catchment area. This captured rain water is transferred into a tank until required for use. When a demand occurs, the rain water is then pumped, either directly to the point of use or via a storage header tank thus displacing what would otherwise be a demand for mains water. In the process, a volume of water is kept out of the storm-water management system, thereby helping to reduce flooding risks. Recycling rain water not only saves money but also helps to reduce the demand on local water resources
Rain water harvesting systems – An introduction
Rain water is captured from the roof(s), and brought to a central point, via normal guttering and down-pipes, to enter a storage tank (frequently underground), where it is filtered on entry. A highly efficient and reliable submersible pump delivers the harvested rain water to a service on demand. Where wished, or a special reason applies, delivery can be to a header tank instead. The size of the storage tank is determined by considering the amount of water available for storage (a function of roof size and local average rainfall), and the amount of water likely to be used (a function of buildings occupancy and function). It is very important not to over-size the rain water tank too much. Further Information can be found at www.ukrha.org
Would rain water Harvesting work for you?
- The external drainage from the roof needs to be modified to bring the water to a central point.
- Space for the storage tank to be sunk into the ground is needed.
- Internal plumbing is usually required to be separated out from the potable or wholesome water supply. The stored water can supply non-drinking water (WC, washing machine & outside tap.)
