Sustainable sips: Firestone Walker's water journey

Water is one of the most precious resources in California. Firestone Walker views water conservation as a vital responsibility for the health of our environment and communities. Fresh water is sourced from a local reservoir, saving the use of about 28,000 m3 of fresh city drinking water.

In 2015, the brewery installed a water treatment facility on campus to process its waste water, for our local utilities and community to use for municipal and agricultural purposes. The remainder is processed, separating out the fine organic material and leaving the water acceptable for delivery back into the city’s wastewater infrastructure. This facility also provides up to 65 kW of energy through anaerobic digestion, where the biogas is used to power a cogen unit.
