Romtec Utilities partnered with LGI Homes to deliver a complete residential wastewater pump station for the Eldorado housing development in Kitsap County, Washington. Initially the scope only included Eldorado, but the system was expanded to include the adjacent development, Verbarendse. The pumping system supports 853 residential lots – 501 from Eldorado and 350 from Verbarendse.

While the lift station was privately funded, it will be owned and operated by Kitsap County Public Works. The pump station is designed to convey wastewater from the developments to the public gravity sewer system.

The lift station project required some specific solutions to meet the demands of a large-scale, multi-phase residential project:
– Multi-phase planning: The system needed to accommodate all four phases of Eldorado, plus future expansion.
– Adjacent development coordination: Verbarendse’s inclusion required upsizing the system and recalculating peak inflows.
– Force main sizing: Initial plans proposed a 4-inch PVC force main, which was insufficient for the project flow. Romtec Utilities identified the need for an 8=inch HDPE DR11 force main to meet Kitsap County standards.
– Site constraints: Overhead utilities and limited easement space required coordination with Puget Sound Energy and civil engineers.

Romtec Utilities provided a complete packaged residential wastewater pump station designed to meet the needs of both developments and comply with Kitsap County’s infrastructure standards.

Romtec delivered:
– Design and engineering: Romtec Utilities designed the structural, mechanical, and electrical components of the system, including stamped plans and calculations.
– Prefabrication: Wet well and valve vault were fully prefabricated and pressure-treated prior to delivery.
– Startup & Training: Romtec provided two days of onsite startup support and training for Kitsap County Sewer Department personnel.
– Warranty: Warranty terms began at system startup and were transferred to the end owner.

The lift station was built for a new residential development in Bremerton, Washington, on the Kitsap peninsula. The growing city is known for its strong infrastructure, scenic waterfront, and proximity to the Puget Sound Naval Shipyard.

Bremerton is just across the Puget Sound from Seattle – approximately 15 miles via ferry. The city is also about 30 miles from Tacoma and 60 miles from Everett. This central location has established Bremerton as a hub for residential expansion and municipal development.

The city’s blend of urban amenities and suburban growth make it an ideal setting for large-scale housing developments, such as Eldorado and Verbarendse. With increasing demand for reliable wastewater management systems, Bremerton continues to be a key area for Romtec Utilities’ engineered pumping solutions in the Pacific Northwest.

Romtec Utilities collaborated with a team of partners to successfully deliver the Eldorado residential wastewater pump station. The project was led by LGI Homes, the developer and project owner, who funded the system with the intent for it to be transferred to Kitsap County Public Works for long-term ownership and operations. Kitsap County played a key role in reviewing and approving the system design, including detailed feedback n hatch ratings, generator specifications, and SCADA integration requirements.

Civil engineering was managed by LDC, Inc., who provided the site plans, elevation data, and force main specification that guided Romtec utilities’ design process. Electrical work was handled by MB Electric, while Miles Resources served as the general and installing contractor.

Romtec Utilities worked with QCC for SCADA integration, ensuring the system could communicate with Kitsap County’s existing infrastructure. Throughout the project, Romtec Utilities’ team maintained close communication with all stakeholders, facilitating design revisions, production timelines, and startup coordination. This collaborative approach ensured the system was delivered on time, met all technical requirements, and was ready for long-term operation by the county.

Romtec Utilities designed the pump system to meet current and future flow demands with flexibility for expansion. The key components were:
– Wet well: Precast 8-foot inner diameter, 19.6-feet deep concrete wet well with protective coating and HS-30 traffic-rated hatch.
– Valve vault: Precast 687 VV with bypass pumping port and Siemens 5100 flowmeter.
– Pumps: Duplex 35HP Flygt NP3171SH submersible pumps with alternating operation and backup float control.
– Control panel: Allen-Bradley CompactLogix PLC with Siemens A1000i pressure transducer and NOLTA MS1 floats.
– Enclosure: NEMA 3R stainless steel enclosure with audible and visual alarm.
– Shelter: Romtec standard 2-post steel shelter for electrical and control equipment.
– Generator: Diesel-powered backup generator with automatic transfer switch.
– Performance:

Initial Duty Point: 189.5 GPm at 119.5 TDH
Final Duty Point: 327.3 GPM at 150.68 TDH

Telemetry contacts provided for integration with Kitsap County’s SCADA system were provided by others.

Romtec Utilities partnered with its sister company, Romtec, to design and supply the architectural structure that houses the systems’ electrical and control component. Romtec provided a standard 2-post steel control shelter. The shelter was delivered with all necessary components for on-site assembly, including structural framing, roofing, and mounting hardware.

By sourcing both the pumping system and shelter from Romtec’s family of companies, developers and municipalities benefit from a single-source solution that improves project efficiency, minimizes risk, and guarantees consistent quality across all components.

The Eldorado residential wastewater pump station demonstrates Romtec Utilities’ ability to deliver pumping solutions for complex residential developments. From initial design through startup and handoff, Romtec provided engineering precision, responsive project management, and high-quality prefabricated systems tailored to Kitsap County’s infrastructure standards.

This project also led to repeat business with LDC, Inc and opened new opportunities in Ellensburg, highlighting Romtec Utilities’ value as a long-term infrastructure partner.
