Sainsbury Curbs Store Water Use by Half Harvesting Rain

April 26 (Bloomberg) -- J Sainsbury Plc, the U.K.’s third-largest supermarket chain, said harvesting rainwater and fixing leaks helped curb water use at its stores by half, the equivalent of 393 Olympic-sized swimming pools a year.

Installing rain-harvesting containers and low-flush toilets at stores and smart meters to identify water leaks to repair helped Sainsbury save “hundreds of thousands” of pounds, Paul Crewe, the London-based retailer’s head of sustainability, energy and environment, said today in a website statement.

A leak found and repaired at a Sainsbury store in Wigan saved enough water a year to fill 21 Olympic pools. The company said such measures cut operational water use by 50 percent since 2005. Tesco Plc is the U.K.’s largest retailer.
