GUERNEVILLE, Calif. — California Water Service’s (Cal Water) Redwood Valley District Manager Gay Guidotti retired this week after leading the district since 1999.

The company has selected Darin McCosker to serve as the new local manager for the district.

Guidotti, a Guerneville native, has been part of the water industry since 1981.

She grew up in the water industry as her family owned and operated Armstrong Valley Water, which started operating in the area in 1948, and is now part of Cal Water’s Redwood Valley District.

Guidotti got her start at Cal Water as an office manager before managing all operations of the district’s Coast Springs, Lucerne and Unified systems.

In her retirement, Guidotti plans on staying in Guerneville and spending more time with her family.

McCosker started his Cal Water career in July 2012 as the superintendent of the Redwood Valley District.

He has worked in the water industry since 1991, eight years of which were in management. McCosker has Water Treatment Grade 5 and Water Distribution Grade 3 certifications from the State Water Resources Control Board, and a Grade 2 Collections Systems Technician certification from the California Water Environment Association.

“Given his years of experience and knowledge of our local communities, Darin is a great asset to our Redwood Valley District,” said Guidotti. “I am confident that he has the experience and vision to keep the district operating smoothly.”

Cal Water serves about 3,600 people through 1,900 service connections in Lucerne and parts of Duncans Mills, Guerneville, Dillon Beach, Noel Heights and Santa Rosa. Additional information may be obtained online at www.calwater.com .
