At the 2014 Annual Dinner, we launched a two year fundraising project, with the aim of raising eur20,000 for the purchase and installation of a complete Water Harvesting system, for the roof of the Heytesbury St. School building. The flat roof provides the perfect foundation for this project to provide the majority of the schools’ utility water – water which is currently costing about eur4,000 per year.
With the school being closed during the summer dryer months, the school year links in quite well with the wetter months. After installing a system in my own home, I have seen that a home 200 litre water butt can be filled in a single afternoon so on this basis, given the expanse of the school roof, a store of about 5,000 litres will be filled in no time.
The costs of the system are for new downpipes, linking back to a single output location, pumps, filtration equipment, and new internal pipework.
