As part of the City of Santa Rosa’s Emergency Groundwater Supply Program, West Yost worked with a well redevelopment contractor to rehabilitate the City’s 10-year old test well at the A Place to Play Park.
Rehabilitation included:
- Video inspection and initial pump test
- Swabbing and brushing
- Chlorination
- Airlift redevelopment
- Pumping redevelopment
- Final pump test and video inspection
The potential yield of the well increased substantially following the redevelopment work. West Yost also prepared well equipping plans and technical specifications to convert the test well into an emergency well. Well equipping included installing a submersible pump, split face block building, tablet chlorination system, plus site work and fencing. The project’s goal was to install the greatest pump capacity to fit into the 8-inch diameter test well.
One project challenge was the high visibility of the test well site, at the west entrance to A Place-to-Play park. West Yost worked with City Water, Public Works, and Recreation and Parks staff to develop architectural features suitable to the location.

“I get jazzed by taking data we collect and telling a story in maps and figures that illustrates to an every-day user what we learned. I get tremendous satisfaction from creating well-crafted images from dense spreadsheets of raw data. For example, for the Colusa project because we
gotstarted with a pile of data and we turned it into maps in a large report that told a story for stakeholders and the general public. It makes the information approachable and understandable.
One of my most rewarding efforts was for the City of Modesto’s Grogan Park Municipal Supply Well. It’s cool to put a big pipe in the ground and get water out of it! It worked exactly as intended, we got clean water at the volume they needed. After that, the City asked us to support them by doing two more projects, the Del Rio Well and Replacement Well 229. They were very happy with all three projects.”

“As a specialist in groundwater-related issues, I greatly enjoy being a part of the strong multidisciplinary teams needed to address wide-ranging client needs. Each client is unique, and each project has its own set of challenges. I enjoy learning about the client’s perspectives on these challenges and coming up with the right approach and team to address them. At West Yost we have the internal resources and team atmosphere that really makes the difference, not just within our groundwater and hydrogeology team, but across the board for water-related services. When it suits our client’s needs, we don’t hesitate to extend that collaborative team-based approach to our teaming partners. It’s great to be a part of these win-win situations!
I am especially proud to be a part of the multidisciplinary teams working to meet a variety of needs for our clients. My clients include agencies such as the Glenn and Colusa GSAs and the Santa Clarita Valley Water Authority as well as municipal clients, such as Sacramento Suburban Water District and the Cities of Davis, Dixon, Vacaville, Milpitas, Modesto, Pasadena, Petaluma, Santa Rosa, and Woodland. We have a long history of providing a variety of planning, modeling, design, and construction management services across multiple disciplines, including water and wastewater services, and it’s very gratifying to know that what I do related to groundwater is part of a bigger picture for our clients, our communities, and the sustainability of our environment.”
