San Ramon's Bishop Ranch reduced its water use by 8.5 million gallons in 2015, a 22.5% decrease from 2014, according to officials from the business park.
Bishop Ranch reached the reduction by implementing a variety of efforts focused on saving water and using drought-tolerant plants, representatives said in a recent statement.
"Water conservation is a top priority as part of our commitment to sustainable principles and practices," said Alexander Mehran, Jr., president and COO of Sunset Development Co., which owns and operates the business park. "That's why we've aggressively pursued and will continue to pursue water conservation efforts in every corner of Bishop Ranch."
The business park's water-saving strategies included monitoring and adjustment of irrigation in the field to avoid broken-down sprinklers, using irrigation-control clocks, removing turf in certain areas, reducing annual flower-planting by 35%, installing drip-irrigation in non-turf landscapes and cutting back water usage by 154,760 gallons in the 2600 building.
Bishop Ranch is also working to install water main lines to bring recycled water to the properties by mid-2016, officials said.
Located on 585 acres in the heart of San Ramon, Bishop Ranch houses 30,000 employees at 600 companies in different industries.
