Sainsbury’s cleans up water footprint
Rainwater harvesting and car wash water reclaim systems have helped Sainsbury’s halve its water consumption across its stores over the last eight years. The company yesterday announced it has reduced its operational water use by 50 percent relative to its growth, resulting in water savings equivalent to nearly one million cubic meters of water annually, or 393 Olympic sized swimming pools.
Sainsbury’s said the achievement was made by finding and eradicating underground water leaks using automatic meter loggers, installing rainwater harvesting in all new stores as standard, and retrofitting rainwater harvesting units in existing stores. The retailer also installed water reclaim units at car washes in 66 of its stores, saving 22,674 square meters of water a year, while low flush toilets and pre-rinse spray taps have similarly helped to save water across its estate.
The efforts form part of Sainsbury’s long term strategy to source water sustainably across its supply chain by 2020. Sainsbury’s head of sustainability, engineering, energy and environment, Paul Crewe, said the strategy would help the company to reduce its impact on the environment and ensure the long-term sustainability of the business.
