British supermarket Sainsbury’s has slashed its water use in half, saving the equivalent of 393 Olympic sized swimming pools each year.
Waterless urinals and rain water harvesting helped the orange-branded shopping giant achieve its target of a 50% relative reduction in its operational water use at the end of March. The retailer has been working with water management firm Waterscan on its water efforts.
In one example, the retailer says a leak repaired at a store in Wigan saved 21 Olympic sized swimming pools worth of water each year (53,710m3).
By installing automated meter readers (AMR) it has been able to identify leaks quicker and cut down mistakes in estimated billing from its water company.
