Romtec Utilities designed and supplied a 55+ residential development stormwater lift station for the Bretton Woods community in Davis, California. This publicly owned pump system serves a 247-home active older adult community with a clubhouse, pool, bocce ball court, and walking trails.

Romtec Utilities worked with Bretton Woods, LLC, Cunningham Engineering, DeNova Homes and the City of Davis to meet municipal standards and site limits. As a result, the project moved forward with a reliable stormwater lift station design for long-term city ownership.

Davis is located in Yolo County, California, near Sacramento and the broader Northern California region. The University of California – Davis gives the city a strong connection to research, planning, and public infrastructure. In addition, Davis sits within a growing regional housing market that supports new residential communities and public infrastructure improvements.

Because Davis manages storm drainage through public infrastructure, the Bretton Woods system needed to support local flood control goals. The City’s stormwater network includes pipes, detention ponds, drainage channels, and lift stations that move runoff away from streets and properties.

The system uses three Flygt 25 horsepower submersible pumps. Together, they move up to 4,000 gallons per minute.

• Precast 12′ ID x  23′ deep wet well
• Precast 816 Valve Vault (w/ Sump Pump)
• Triplex Flygt 25hp submersible Pumps
• Primary Controller: CompactLogixs #1769-L30 ER
• Primary Level Sensor: Vega C23 Radar Transducer
• Secondary Level Sensor: Vega C23 Radar Transducer
• Backup Level Sensor: (5) NOLTA MS1 Floats
• NEMA 3R MCC Sections

Romtec Utilities’ sister company, Romtec, provided a shelter for the pump system.

The existing force main created the biggest design challenge. It runs beneath a major roadway, so the project team could not remove or replace it. Therefore, Romtec Utilities had to design the stormwater lift station around that fixed condition. The City of Davis applies pump system standards that closely match wastewater standards. Because of this, the system needed a municipal-level design for controls, reliability, and review approval.

Romtec Utilities designed the 55+ residential development stormwater lift station around the existing force main. At the same time, the drainage system met the required discharge rate for the ponds and culverts that collect stormwater during rain events. Romtec Utilities submitted the design through Cunningham Engineering for review and approval by the City of Davis. As a result, the developer received a coordinated pump system design that supported permitting and future construction planning.

K Hovnanian recommended Romtec Utilities to Bretton Woods, LLC and Cunningham Engineering for the drainage pump station design. At first, the project included two pump stations. One station would be privately owned by the HOA. The other would replace an existing City of Davis system. However, the scope later changed to one publicly owned stormwater lift station. The City of Davis became the owner.

Cunningham Engineering supported the civil design and coordinated with the broader review team. Romtec Utilities worked with Bretton Woods, LLC, the City of Davis, BKF, Yolo County, and Pacific Hydrologic Incorporated during the submittal and approval process.

Romtec Utilities provided the 55+ residential development stormwater lift station for the Bretton Woods community in Davis, California. The final design addressed the development’s stormwater collection layout, the existing force main, and the City of Davis standards for publicly owned pump systems. In turn, the project gave the developer a clear path for review, approval, and future construction.

This project shows how developers can reduce risk on stormwater pumping projects. Romtec Utilities helps engineers and developers design systems around owner standards, AHJ requirements, and site constraints. Therefore, the final design can meet public ownership needs without adding unnecessary cost or delay.
