Leafield making the most of the rainy days

Posted: Monday 17th September 2012

Rainwater harvesting saves money and water. Leafield can now advise from experience as their own Rainwater harvesting scheme is fully functional and saving 3 tonnes of water a day.

During the accreditation process for BSI ISO 14001:2004, the decision was made to install a rainwater harvesting system for toilet flushing and machine cooling in their manufacturing plant. The roof area of the Leafield premises and expected annual rainfall for the South West made the Rainwater Harvesting project a feasible scheme.

The system comprises 3 x 10,000 litre CT2200 JA water tanks, a large filter to remove the debris and a pressure sensitive pump that starts as soon as a demand is felt.

Jon Finch, Engineering Manager at Leafield who is managing the scheme said “the collected rainwater supplies all the toilets within the building and also the machine cooling systems. Using harvested water for machine cooling has an added benefit to us in Corsham as it will reduce the amount of limescale build-up. Each working day we expect to save up to 3 cubic metres of mains water – equivalent to a mass of 3 tonnes”.
