No agency has unlimited resources; risk reduction is one of the best ways to allocate those limited resources. Ewers Engineering develops risk models for a range of purposes to ensure those resources provide the maximum benefit to the agency's customers. Here are three tools we develop from our work with risk reduction to support our clients:

Public Works enablement

At Ewers Engineering, we design for 100-year service durability in our pipelines, tanks, pump stations, and treatment facilities.


History says few facilities will last that long; utilities are often on the losing end of statistics. We at Ewers Engineering know our designs last as long as they're supported by operations and maintenance. That's why we work hand-in-hand with client agencies to develop programs that extend the service life of their facilities. Whether it's a great design for a pipeline or a successful implementation of the condition assessment program that will support that pipeline, we develop infrastructure to last.

Wastewater treatment plant optimization, Computerized Maintenance Management System (CMMS) development, pipeline design, force main condition assessment, Fats Oils Grease (FOG) control programs, risk-based Capital Improvements Program (CIP) software. Our services (and even products) are varied, but they all serve our clients' long-term need to effectively, efficiently, and dependably serve their customers. Like our clients, our long-range vision drives quality, creativity, and technical expertise. We are founded on a fascination with water, wastewater, and storm water.

That passion makes our services broadly applicable and diverse. We have directly contracted with agencies throughout California to provide the following services:

  • Design and construction services: Storage structures, pumping stations, pipelines, dams.

  • Planning: Hydraulic modeling, watershed modeling, risk model development (integrating with CIPs, condition assessment programs, and CMMSs, performance and qualitative bench-marking.

  • Program development: FOG control programs, CIP creation and development, force main condition assessment programs, emergency response programs.



Our clients understand us to be problem-solvers dedicated to their interests. Contact us to discuss how we can help you with your agency's challenges.



Force Main Condition Assessment Program Setup

Force mains represent the biggest pipeline liability headache for sanitary sewer agencies. They're expensive to construct, are critical to collection system and treatment operations, tend to include materials and equipment not found anywhere else in collection systems, and are difficult to inspect. We use a logical, risk-based, systematic approach to condition assessment to minimize its impact on agency resources. Client agencies have used us for staff extension approaches to leapfrog the important past the urgent, allowing them to:

  • Develop force main longevity by minimizing force main lifespan-shortening factors like hydrogen sulfide entrapment, transient pressure events, and out-of-range velocity and pressure operations

  • Build staff understanding and preparedness with Computerized Maintenance Management System (CMMS) integration and work planning

  • Prioritize improvements to best serve the agency's customers by addressing the highest-risk elements first

  • Demonstrate management excellence to bolster public support and reassure regulators

  • Improve system design with better equipment and supplier interfaces (particularly for air vacuum valves) and hydraulics-based system troubleshooting


Agencies often cannot justify hiring new personnel to administer a Fats Oils Grease (FOG) Control Program or champion and execute a Force Main Condition Assessment Program through the first resulting Capital Improvements Program (CIP) projects. Ewers Engineering offers a small, knowledgeable staff to perform administrative tasks to keep its client systems in compliance and extend the lifespan of their collections systems.

FOG Control Program setup

Fats, oils, and grease (FOG) control drives infrastructure lifespan at community collections system hotspots, and uncontrolled FOG can imperil wastewater treatment plant staff with hydrogen sulfide attacks on supporting infrastructure.  The FOG control program is a requirement of California Safe Drinking Water code, but we develop programs that work. Whatever the size of your agency, we provide a cafeteria-style set of services, from turnkey design and implementation to help with a single issue.

  • Municipal code review for currency, compliance, and conflicts

  • FOG Control Program Plan development, from inception to final implementation phases

  • Work planning to predict resource needs and ease outsourcing

  • Program software selection to enable remote inspection data input and Food Service Establishment (FSE) mailings, if needed

  • Communications planning to maximize public outreach effectiveness

Hydraulic modeling/loss estimation

Hydraulic modeling gives agencies the capacity to evaluate system behavior under extremes, to perform failure consequence assessments, assess water quality developments and try solutions, project capital projects needs, and detect abnormal performance that indicates failure or maladjustment. We have worked with models from the dawn of the technology through the range of current, GIS-driven models.


Ewers Engineering also provides water loss estimating software customized to its clients' needs to accommodate water loss reporting to the State of California.
