Infrastructure Services
Innovative solutions for storage, conveyance and collection from client-focused designers and engineers
West Yost’s Infrastructure team works in unison with our planning, treatment, OTCR and construction management staff to deliver designs that not only meet client objectives, but also consider safety, risk, and long-term, system-wide viability. We listen and collaborate with system owners and their staff, so that our designs are informed by a comprehensive project understanding, conform to client standards, and are readily constructible. Our methodology employs innovative practices, such as consequence-driven cyber-informed engineering, and constructability reviews early in the design process to deliver the highest value project for our clients.
Over the past 30 years, our infrastructure experts have designed 100 storage facilities, pump and lift stations of every type and size, and more than 150 miles of large and small pipelines. We also excel at facility assessments and rehabilitation design; allowing clients to extend the life of their system components and best prioritize infrastructure spending. Whether you are planning or operating a water, recycled water, sewer, or combined collection system, the West Yost Infrastructure team is ready to provide solutions to meet your community’s needs and growth.
Project Highlights
Sweeney Ridge
City of San Bruno
West Yost is designing upgrades and repairs to a water tank and pipelines for the City of San Bruno, California. The steel pipeline is 70 years old and in a hard to access area with steep slopes that can exceed 30% and covered in poison oak. Fixing leaks on this pipeline has proved to be very difficult for City staff, and a major failure of this pipeline would be problematic for the City. The 70 year old steel water tank has experienced severe corrosion from proximity to the Pacific Ocean.
Riverfront Interceptor Sewer Lift Station and Forcemain Project
City of Albany
In 2019, West Yost provided predesign, design, and construction services for a new wet weather lift station and force main and for rehabilitating the Riverfront Interceptor for the City of Albany, Oregon. The Riverfront Interceptor is the primary pipeline that conveys wastewater from the City to the Water Reclamation Facility. It ranges from 30 to 54 inches, is a deep pipeline, and is very close to both the Willamette River and to an active railroad line. The forcemain and lift station are used to bypass the interceptor during peak wet weather flows. This bypass and rehabilitation resolved problems with sanitary sewer overflows into the Willamette River and was less costly than replacing the interceptor.
Driscoll Main Renewal
Alameda County Water District
Pipelines in the Alameda County Water District are nearing the end of their useful lives and need replacement. There are also portions of the conveyance system that will be upsized to better provide water service to customers and reduce transmission inefficiencies. West Yost is designing more than seven thousand feet of new water mains, which includes a crossing of Mission Creek, and will provide bid support and construction services. Construction is scheduled to begin in April 2021.
Sycamore and Agua Mansa Lift Stations
City of Rialto
West Yost is designing upgrades to increase the sewer capacity in two regions of the City of Rialto to support new development. The Sycamore Lift Station will have upgrades to increase capacity from 450 gallons per minute to 560 gallons per minute and the Agua Mansa Lift Station will increase capacity almost six-fold from 250 gpm to 1,470 gpm. The project included a condition assessment in order to determine the existing condition of the wet wells at each lift station and the condition and capacity of existing electrical equipment to support the expansions.
Highlands ARD (4/5) Sewer Relief
Sacramento Area Sewer District
West Yost is designing over 14,000 feet of force main and gravity sewers to provide relief to the existing sewer system that is currently experiencing flows above what was originally designed. West Yost is also designing a replacement lift station. West Yost has been working on this project since the project development/predesign phase and will provide bid support and construction support services.
Glenview Water Storage Tank 3
City of San Bruno
West Yost provided design and support during construction for a 2.0 MG prestressed concrete tank with a dome roof to replace a 60-year old concrete tank. The project site is located within 300 feet of the San Andreas Fault and sits between two faults just north and east of the tank. This tank is a critical component in the City’s day-to-day operation of its water supply system and provides emergency fire storage.

“What I love about my job is helping people solve problems, whether they are clients or staff. It is extremely rewarding when a client calls with a difficult challenge keeping them up at night and I am able to pair them up with the ideal staff to provide a solution. As a business sector leader, I focus on my excellent team feeling satisfied and passionate about their work. Sometimes I facilitate changing around assignments to capitalize on their strengths, I want to make sure they feel fulfilled by their work.
The Washington Park Project has been an amazing experience. I am able to help a client with an extremely complicated project and assist them in managing a large number of stakeholders. Together we’ve achieved many successes through completed coordination efforts. For example, a piece of the design was not fully formulated and I was able to bring the geotechnical, civil, mechanical, and structural engineers in with the client and contractor and say “we are not leaving the room until we have a solution”. This resulted in very out-of-the-box thinking that really solved their problem with a unique solution and the client was very satisfied.”

“I like the collaboration part of our projects where we get different perspectives from staff and clients to have the best outcome possible. If we design a pump station for a year and someone is going to be operating it for their entire career – we want it to be most efficient for them so they are happy in their jobs. So I enjoy collaborating with them to get it right.
Irvine Ranch Water District Replacement Planning Model Phase 2, it was part of their asset management plan and our update was to put cost to all of the rehabilitations that they plan to do for the next 100 years (for instance replacing pumps and pipelines, rehabilitating pumps and motors). I’ve been designing facilities for them since 1991, and put a lot of effort into those projects. With this assessment, I was able to have influence over extending the lifecycle of those projects. And the clients extolled it as stellar work!
