Featured Projects
Water

Project

Southwest Area Tank & Pump Station
City of Woodland, California

West Yost provided the predesign, design, and construction management and inspection for a partially buried, 3 MG potable water concrete storage tank and a 6,000 gpm booster pump station located in the City’s David Douglass Park.

Project

Aquifer Storage and Recovery Wells
City of Roseville, California

The objective of Roseville’s Aquifer Storage and Recovery (ASR) Program is to store surplus drinking water (10,000 acre-feet per year) in the underlying aquifer during periods of normal and above normal precipitation. This stored drinking water is then extracted and served to meet peak demands. West Yost provided design and construction management services for two ASR wells for the City.

Project

Aquifer Storage & Recovery (ASR) Well 28
City of Woodland, California

The Woodland Davis Clean Water Agency (Agency) and the City, in conjunction with West Yost, conducted an evaluation of ASR as a component of the overall water supply for the Davis Woodland Water Supply Project (DWWSP), designed the first ASR facility for the City, completed construction of the project, and have recently begun injection testing for the ASR well.

Overview

Rights / Transfers Projects
Water

Project

Water Supply Planning and Water Rights
Woodland-Davis Clean Water Agency, California

In the early phases on the Davis Woodland Water Supply Project, the timeliness for pursuing the existing area-of-origin water right was critical. West Yost assisted in driving the application through the process, including testifying at the hearing to the State Water Resources Control Board. After this water right was secured, additional water was still needed in key summer months to address shortages due to Term 91 conditions.

Project

Water Transfer
Conaway Conservancy Group / Conaway Ranch, California

West Yost began working with Conaway Ranch to get an early start on developing a water transfer program, identifying key technical and policy issues, opening discussions with DWR and USBR staff, and holding preliminary discussions with potential buyers.This successful transfer of 12,000+ acre-feet of water was accomplished through savings of crop water consumptive use, through a combination of land fallowing and shifting to crops with lower water use.  West Yost developed a comprehensive Conaway Ranch land and water use plan based on farm economics and practices.  A key part of this project was maintaining wildlife-friendly agriculture – a hallmark of Conaway Ranch.  

Project

Supplemental Water Supply Acquisition
City of Tracy, California

Due to increased demands, the City needed to obtain additional water supplies to supplement two existing sources. West Yost assisted the City with initial meetings with potential supplies, initial water transfer assignment agreements, and follow-up, leading to a 5,000 acre-feet annually (afa) of contract water with an option for an additional 2,500 afa.

Project

Integrated Regional Water Management Planning
Northern Sacramento Valley Regional Water Management Group, California

West Yost is working with the six county Northern Sacramento Valley Regional Water Management Group (NSV RWMG) on their first collaborative Integrated Regional Water Management Plan (IRWMP).

Project

IRWM RAP and Grant Application Assistance
Westside Region, Water Resources Association of Yolo County, California

West Yost prepared a Region Acceptance Process (RAP) grant eligibility application and submitted it to the California Department of Water Resources (DWR) on behalf of the Westside Region member agencies, which include the Water Resources Association of Yolo County (WRA), Solano County Water Agency, Napa County Flood Control and Water Conservation District, Lake County Watershed Protection District, and Colusa County Resource Conservation District (RCD).

Project

Integrated Water Resources Plan
City of Fresno, California

West Yost provided an update and refinement to the Fresno Metropolitan Water Resources Management Plan (Metro Plan), which includes a key focus on conjunctive use for long-term supply reliability and sustainability.

Project

Water and Recycled Water Planning
Dublin San Ramon Services District, California

West Yost worked with the District to provide master planning for both its water and recycled water systems, and to provide the design for water and recycled water facilities. During this project, the West Yost team used a  collaborative approach to create a plan that maximizes the benefit of recycled water as a long-term resource.

Project

Hydrogeologic Characterization and Modeling Study for South East Bay Plain Basin Groundwater Management Plan Development Project
East Bay Municipal Utility District, California

The South East Bay Plain (SEBP) basin study was conducted to support development of EBMUD’s Groundwater Management Plan (GMP) as part of EBMUD’s efforts to implement conjunctive use to improve water supply reliability. The project study area includes the City of Hayward.

 

 

 

 

 

 

 

 

 

 

The project included the following activities:

Project

ASR Program Development and Modeling, Davis-Woodland Water Supply Project
Woodland-Davis Clean Water Agency, California

The Woodland-Davis Clean Water Agency is a Joint Powers Authority representing the water supply interests of the cities of Davis and Woodland. Under the Aquifer Storage and Recover (ASR) Program, the City of Woodland is implementing a comprehensive ASR Program to help address its water supply needs during periods of peak demand and/or drought. The City of Davis may also choose to undertake its own ASR Program.

Project

Grogan Park Production Well
City of Modesto, California

West Yost is providing hydrogeologic and engineering for the City’s Grogan Park (formerly known as the Tivoli Well) Production Well. The goal of this project is to construct a new municipal well with the capacity of approximately 1,000 gpm or more without the need for wellhead treatment.

Project

Sunset Well Rehabilitation
South Tahoe Public Utility District, California

West Yost evaluated, rehabilitated, and tested the Sunset Well to reestablish well efficiency and normal flow conditions. This project included conducting a condition assessment of the well and down-hole equipment, measuring the well performance before and after rehabilitation including an assessment of the maximum sustainable yield, and sampling for Title 22 drinking water constituents.
