City of Sandpoint, Downtown Decorative Street Lights Phase 2

This project applied decorative street lighting standards and tree well receptacles for decorative winter tree lighting along sections of downtown streets in Sandpoint, Idaho. The design effort included a new combination meter/power/lighting control pedestal and design of underground raceways and wiring, sized for voltage drop for the circuits. Underground fiber ducts and vaults were also installed to move overhead fiber optic infrastructure underground, for use by multiple providers. Between the completion of Phase 1 of the project and the beginning of Phase 2, the City’s preferred decorative light standard manufacturer went out of business. We worked with City staff and lighting supplier to select a new, comparable standard that the City could use for this and future projects.

City of Quincy, B Street NE Roadway & Infrastructure Improvements

This project involved the installation of pedestrian pathway and sidewalk lighting, as well as intersection lighting, for a section of street in Quincy, Washington. The design process included creating a new combination meter and power pedestal, along with the design of cobra head lighting according to utility standards. The pedestrian lighting fixtures were selected based on the type already in use by the City in a local park.

Town of Lind, Well #8 Starter Upgrade

This project involved replacing an existing soft starter and motor at a municipal well with a new variable-frequency drive, along with refurbishing the motor specifically for compatibility with the variable-frequency drive. The well pump is a 300-horsepower vertical shaft turbine type. One of the project's main challenges was finding adequate space for the new electrical equipment. A portion of the building was designed to be removable to allow access for pulling the well pump. As a result, a dry-type transformer was relocated to the exterior of the building. A new, cabinet-mounted variable-frequency drive was installed, and its controls were integrated with the existing well control panel. Additionally, the harmonic filter was designed to be disabled when the well house operated on generator power to prevent any issues with generator voltage regulation.

City of Tekoa, Wastewater Treatment Plant Intake Pump Station Replacement

This project included construction of a new above-grade triplex submersible pump station. The pump station included separated rooms for the wet well and piping and electrical equipment. The wet well room included explosion proof electrical equipment, lighting, and an explosive gas detection system. The piping and electrical equipment room included local pump control, intrinsic safety equipment, and lockable disconnecting means for the pumps. The pumps were operated from variable frequency drives installed in a custom UL508A control panel installed in the operations building. The panel included a remote terminal unit and human machine interface for automatic control, monitoring, and ease of use for changing functional setpoints.

Confederated Tribes of the Chehalis Reservation, Wastewater Collection System & Wastewater Treatment Facility Improvements

Century West managed sewer improvements for the Chehalis Tribes, which included installing a new septic tank effluent collection system for 21 homes and 5 tribal buildings using over 8,300 linear feet of PVC pipe and two, 100 gallon-per-minute pump stations. Century West also evaluated the existing treatment plant. The membrane system was deemed capable of treating flows for the next 20 years without requiring expansion. Thus, the team proposed enhancements, including new pump stations, piping, electrical controls, and various facility upgrades.
