Recycled Water Deliveries Set New Records in 2017
In 2017, customers in Dublin, San Ramon and Pleasanton used a total of 1.39 billion gallons of recycled water. On ten hot days in the summer of 2017, customers used every drop of available recycled water from the Jeffrey G. Hansen Water Recycling Plant in Pleasanton. Even as a wet winter helped California emerge from one of the worst droughts in history, the region's recycled water usage increased over 2016's prior record of 1.05 billion gallons. By using recycled water on landscaped areas, customers help save precious drinking water in dry and wet years alike.
New customer connections in DSRSD, EBMUD and Pleasanton service areas were the driving factor in 2017's 32 percent increase in recycled water use in the past year. To keep pace with the expanding system, the San Ramon Valley Recycled Water Program (SRVRWP) has optimized operations and began constructing a new treatment plant expansion. In 2018, SRVRWP will complete the expansion project and continue seeking new sources of water to meet growing demands.
"It takes a lot of coordination and skill to treat and distribute recycled water daily," said SRVRWP Authority Manager Michael Tognolini, "the plant operators did a great job not only on those ten days last summer, but all year long."

DERWA Board Appoints Michael Tognolini Authority Manager
James Bewley Retires
DUBLIN, CA - The Dublin San Ramon Services District (DSRSD) East Bay Municipal Utility District (EBMUD) Recycled Water Authority (DERWA) Board of Directors appointed Michael Tognolini as Authority Manager, effective April 1, 2016, upon the retirement of James Bewley, who served in that position for ten years. DERWA, the governing body of the San Ramon Valley Recycled Water Program (SRVRWP), is a joint powers authority formed in 1995 between DSRSD and EBMUD to provide a safe, reliable, and consistent supply of recycled water to irrigation customers in Dublin, San Ramon, Danville, and Blackhawk.
Michael Tognolini has worked on water resources planning and development projects for EBMUD since 1996. As Manager of Water Supply Improvements since 2007, he has been responsible for long-range water supply planning and the development of new sources such as groundwater storage, water transfers, desalination, and water recycling, including expansion of recycled water projects in San Ramon, Oakland, and Emeryville. Tognolini led EBMUD's efforts to construct the Freeport Regional Water Project in Sacramento County to provide much-needed water to EBMUD customers during drought periods. In addition, he led the development of EBMUD's Water Supply Management Program 2040, a comprehensive water supply plan for the next three decades.
Prior to EBMUD, Tognolini served as a consulting engineer at Kennedy/Jenks Consultants in San Francisco. He earned a Bachelor of Science in Civil Engineering and a Master of Science in Environmental Fluid Mechanics and Hydrology from Stanford University.

About the San Ramon Valley Recycled Water Program
In 2015, the SRVRWP saved more than a billion gallons of potable water by supplying recycled water for irrigation. Recycled water deliveries began in early 2006 when construction of the program's first phase was completed. The SRVRWP's main transmission pipeline connects to DSRSD and the EBMUD pipelines that serve golf courses, parks, greenbelts, roadway medians, schools, office complexes and common areas in homeowner associations. DSRSD supplies recycled water to Dublin and the Dougherty Valley area of San Ramon. EBMUD supplies portions of San Ramon and plans future expansions in San Ramon, Danville, and Blackhawk.
In 2014, the City of Pleasanton signed agreements with the SRVRWP partners, paving the way for a recycled water program in Pleasanton and expansion of the Jeffrey G. Hansen Water Recycling Plant. Pleasanton converted irrigation to recycled water at Val Vista Park in 2015. The city will finish constructing recycled water pipelines to serve several other municipal parks and the Hacienda Business Park in 2016.
