Our services include power system studies, preliminary engineering and detailed design, design of medium and low voltage distribution, design of busways, transformers, switch gears, standby power generation design, lighting design, PLC control system, and fire alarm and security systems.
Water & Wastewater Projects
Seattle Public Utilities,  Ship Canal BEWP Tunnel design and TEPS – Seattle, WA
Elcon provided design and engineering services to provide Seattle City Light (SCL) 26.4kV incoming service for temporary power supply to the tunnel boring machine (TBM) and other temporary and permanent loads to support construction for the Ship Canal Water Quality Project (SCWQP).
Willamette Water Supply Project, Water Treatment Plant 1.0 – Sherwood, OR
As a partnership between Tualatin Valley Water District and the City of Hillsboro, the Willamette Water Supply Project (WWSP)'s Water Treatment Plant ("WTP_1.0”), will be located in Sherwood. The plant features an initial treated water design capacity of 60 million gallons per day ("mgd") and future build-out treated water design capacity of 120 mgd. Elcon is currently performing electrical design services for the project. 
BES, Columbia Boulevard Headworks Screen Replacement – Portland, OR
The Columbia Boulevard Wastewater Treatment Plant is part of a collection and treatment system that serves nearly 600,000 Portland residential and commercial customers. With sewage pump stations and pipes transporting wastewater to the facility 24 hours a day, the need for improvements is a continuing process. Elcon is currently performing electrical design services for the project. 
EWEB, Shasta water pump station – Eugene, OR
Eugene Water and Electric Board (EWEB)'s Shasta 1150 Pump Station consists of six new pumps controlled via Variable Frequency Drives (VFD), new switchgear and motor control center with integrated Programmable Logic Controller (PLC) and Human Machine Interface (HMI), automatic and manual transfer switches, transformer and distribution panel with communication via Ethernet connection.

Elcon designed the control system interfacing the PLC with pressure, flow and temperature transmitters for pump control and SCADA functions. Elcon designed a new standby diesel-engine generator and automatic transfer switch. In addition, to the new engine-generator set we also designed a connection using Posi-Lok connectors and kirk-keyed breakers for connection of a trailer mounted portable generator. Elcon also performed all calculations, developed a construction cost estimate, and provided assistance during the construction phase of the project by answering RFIs and submittal reviews.  
BES, Lombard Street Pump Station – Portland, OR
Elcon Is providing upgrades to the existing Lombard Street pump station to increase its reliability and to extend its service life. Services include a pump station refurbishment upgrade to the existing 277/480VAC, 3-phase electrical service by a pad mounted transformer, stand-by power system design, SCADA and instrumentation systems design, and construction administration. Elcon is working closely with Portland General Electric to confirm if the existing PGE transformer is adequate and provide the design for the service upgrade as required.

BES, 94th and Broadway Wastewater pump station – PortlanD, OR
As part of the BES Pump Station Improvement Program, the Broadway and 94th Avenue pump station upgrade was assessed as needing upgrades due to equipment condition age, lack of accessibility and vehicle parking, drainage issues, and diesel engine generator and fuel system maintenance issues. BES was seeking a consultant for the demolition of existing equipment and the design of a new pump station that would contain two new pumps, new switchgear, and routing of a new primary service with a 480VAC, 3-phase pad mounted transformer. Elcon coordinated the design of the control system and interfacing the SCADA functions. Elcon designed a new standby diesel-engine generator and automatic transfer switch. In addition, to the new engine-generator set, Elcon also performed all calculations, developed a construction cost estimate, and provided assistance during the construction phase of the project by answering RFIs and submittal reviews.
