Services
Ewers Engineering, Inc. (EEI) is a Roseville, California-based civil engineering firm specializing in water, wastewater, and stormwater design and planning. Our range of services springs from problem-solving the central question, “What keeps you up at night?”. This question has resulted in some great outcomes for agencies. We have developed software for CIP development and management, a treatment plant handrail failure analysis and replacement policy, combined water and wastewater emergency response plans, and buried infrastructure condition assessments. How can we help you?
Planning
-
Underground facility condition assessments can help agencies maximize their return on investment (ROI). Ewers Engineering has worked exclusively with water, wastewater, and stormwater agencies since its inception, helping them determine what is known, what is needed, and how to take meaningful action, using system criticality as a guide. All assessments are conducted independently, without any obligation or affiliation with product or service vendors. We’re also happy to provide a complimentary audit of your condition assessment program. Let us know if this would be helpful in getting your program started.
-
Ewers Engineering partners with agencies to create CIPs that are consistent, transparent and accessible to diverse audiences. Our CIP management software, RD/CIP, ranks projects by failure risk, forecasts costs from inception, and estimates the staffing required, while also recommending project sizes and quantities.
-
Hydraulic modeling for water, wastewater, and stormwater doesn’t need to cover the entire system. We design focused models that target specific challenges, ensuring they stay up to date while reducing unnecessary costs for agencies.
-
By bringing together a range of perspectives, we enhance emergency response and planning for water, wastewater, and stormwater systems, consistently meeting and surpassing regulatory requirements.
Design and Construction
The benefits of experience
With experience spanning a wide range of projects, we bring proven standards and a dedicated team of insightful professionals to every job. We get it done.
-
Conduct route surveys and optimal route selection with multiple variables; design for metric or imperial systems; integrate pressurized or nonpressurized pipelines into crowded urban corridors; trenchless installation design; pipeline rehabilitation; and existing pipeline optimization to extend the service life
-
Update current or create new standard drawings and specifications to meet the agency’s objectives
-
Sizing pumps and determining optimal configuration for applications, developing hydraulics of upstream and downstream systems, and integrating tricky constraints like large protected trees on site
-
Inspection, prebid meetings, cost/bid assessments and recommendations, RFIs, quantity takeoffs, daily reporting, scheduling and tracking with CPM
20th Annual Sewer and Stormwater Summit:
Presentation Resources
As a civil engineer, I'm often asked to work on a pipeline or pump station that has failed. Of the many ways an agency can prepare for failure, I'm going to make the case for refining your lift/pump station allowable outage times before a force main or pump station fails.
If you're new to collection systems, this topic may be a little strange. To simplify: How long can your pump stations be shut down today? At noon? At 8 a.m.? How about after a big winter storm in February? Any repair, and replacement projects on pump stations, force mains, or treatment facilities is affected by these shutdown times. If pump station shutdown times aren't known, a downstream failure can become a frantic push to truck wastewater, even if it's not necessary. Overly conservative shutdown period estimates can dramatically increase costs of even minor repairs and the time to complete them with construction of bypass facilities. The unknown shutdown times also highlight a lack of planning and standard operating procedures that would increase the resilience of your collection system, something required by the California Water Boards through the Waste Discharge Requirements.
I will discuss the regulations requirements, the ways and costs of bypassing failed pipelines or pump stations (yes, including trucking), rough target outage times for common downstream work, and a simple way to get those pump station outage times defined and refined for diurnal and seasonal changes. We will review the steps for checking and calibrating pump shutdown times.

PRESENTATION HANDOUTS
CWEA Annual 2025 Conference:
Presentation Resources
This is to provide attendees with handouts for “Reissued WDR - Compliance Best Practices,” conducted by Jim Fischer, Sam Rose, and Rich Cunningham of Fischer Compliance, and Chris Ewers of Ewers Engineering April 24, 2025. Chris focused on implementation of the Attachment D, Section 8 portion of the WDR that mandates system evaluation, risk assessment, capacity assurance, and capital improvements progress.

CSRMA Webinar: Learning to Love WDR Compliance for Force Mains
Presentation Resources
This is to provide attendees with the slide handouts for “Learning to Love WDR Compliance for Force Mains,” presented and recorded June 18, 2025. Chris walked attendees through the requirements in Attachment D, Section 8 portion of the WDR (system evaluation, risk assessment, capacity assurance, and capital improvements), a fast, effective process to get compliance, and the benefits of doing so.

EEI Volunteerism
Workdays: Placer Land Trust
The Placer Land Trust uses conservation easements and purchases to make some of the beautiful country of the Sierra foothills accessible to all in service of the community. EEI’s volunteer efforts have been to help clear trails for easier access (particularly after a big blow downed trees, as here). Come and join us for a work day! It’s great fun with some of the best people you can hope to meet. Or join us for a hike on the trails we help maintain and build to appreciate what an astoundingly beautiful place we live in.
Environmental improvement: Prescribed burning on public and private lands
One of the most puzzling and confounding elements of the beauty and fecundity of the West is in the role of fire here. Suppressing fire for too long locks up nutrients, builds fuel loads in the forest understory, and reduces species diversity. Chris Ewers has been working with the County Resource Conservation Services and Burn Associations in Placer, Nevada, and Yuba counties on public, private, and trust lands to help implement prescribed burns. There’s an amazing education here, fantastic outcomes, and much to be done. Come and get involved! We are building a future for our forests that displaces burned-out moonscapes and fearful communities with vibrant, cared-for, species-rich places.
