Water Services

The Water Business Sector is a cohesive and collaborative team whose combined expertise brings value to our clients during the utility planning process. We provide planning, modeling, and regulatory services for recycled water, drinking water, wastewater, and stormwater utilities. Our team is adept at master planning. We are often completing multiple plans concurrently. Recent examples include the City of Stockton’s Water System and Collection System Master Plans; and the City of Garden Grove Water and SCADA Master Plans, where West Yost was able to incorporate the City’s AWIA compliance while preparing recommendations to implement their SCADA master plan. This team provides comprehensive services for drinking water, from Urban Water Management Plans to surge and transient evaluations.

As recycled water becomes an integral part of water conservation, West Yost is actively innovating how we maximize its use. Our teams bring new technology and tools to the evaluation of internal plumbing, cross connection control, system conversion, and testing. We assist our clients with Title 22 recycled water treatment, recycled water use planning studies and the development of funding streams, including grants.

Our collection systems team provides planning, flow monitoring, and hydraulic modeling for collection systems and combined sewer/stormwater systems. They work with utilities to meet their regulatory requirements for sewer system management plans updates and offer recommendations to help municipalities manage growth. Our stormwater group, who are leaders in stormwater system planning, regulatory compliance and design of needed storm system improvements, complete this robust group of planners, modelers and compliance specialists.

Stormwater Capital Improvement Program Master Plan

City of Rancho Cordova

Here, West Yost is finishing the stormwater master plan, which focuses on evaluating the City’s trunk storm drain system. We have also completed hydraulic and hydrologic modeling for existing conditions and for evaluating improvements. West Yost has completed the data collection and condition assessment field work activities to confirm the configuration of the trunk drain system and define its condition.

Recycled Water and Alternative Water Supply Planning

Stanford University

West Yost has advised Stanford on recycled water use opportunities on campus since 2010. As part of our work for the university, West Yost prepared a recycled water white paper that outlines potential campus-related recycled water uses, recycled water regulations, permitting issues, and water quality.

Recycled Water Support Services

City of Oceanside

Our team is assisting the City of Oceanside with recycled water projects, including retrofit plans, plan review, inspections, annual inspections, and shutdown testing services. As part of this effort, our team will prepare site conversion evaluation reports for 68 sites (300 meters). The City’s customers who recently converted to recycled water include the Goat Hill Golf Course and the El Corazon Sport Complex (18 soccer fields). As the City’s representative, our staff coordinates with the San Diego County Department of Environmental Health, the State Water Resources Control Board, and customers.

Water Master Plan and SCADA Master Plan

City of Garden Grove

West Yost recently completed the City of Garden Grove’s Water System Master Plan Update. The City, located in north central Orange County, has an 18-square-mile service area and is close to being built out. The principal challenges facing the City include aging infrastructure and capacity issues associated with older small-diameter mains. West Yost updated the distribution system hydraulic model, planned and completed a field program to collect hydrant flow test data, calibrated the model pipeline roughness values using the field data, and verified the model comparing model operations to SCADA data.

Water Master Plan Update and Collection System Master Plan Update

City of Stockton

West Yost is preparing an update to the City’s Water and Collection System Master Plans. These efforts will provide an evaluation of water system and collection system infrastructure needs. The master plans will support buildout identified in the recently updated Envision Stockton 2040 General Plan with an updated capital improvement plan. After collaborating with the City to confirm project goals, priorities, and strategies a number of tasks are planned.
