Water & Wastewater Projects
Seattle Public Utilities,  Ship Canal Water Quality Project
27 KV TEmporary Power and STORAGE TUNNEL Electrical Design – 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).
Elcon is responsible for the design of the 24.6 kV primary service to a 2,500 kVA utility transformer and the 480V, 3 phase secondary electrical service. Elcon designed power, metering, lighting, security,  fire alarm systems, and all control and instrumentation conduit wiring and terminations. Elcon was responsible for interfacing the control and SCADA functions. Elcon will provide and assist with project programming, management, electrical specifications, performed all calculations, developed construction cost estimates, and will perform construction assistance.
City of Portland 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.  
City of Portland BES, 94th and Broadway
Wastewater pump station – PortlanD, OR
The City of Portland’s Bureau of Environmental Services (BES) commissioned their first ever BIM project to upgrade the pump station located at 9340 NE Broadway. This project will replace the existing pump station with a new larger pump station, which will increase pumping capacity, enhance accessibility for maintenance, and improve drainage. This upgrade will also help protect public health and the environment by reducing flooding and sewage backups to homes, businesses, streets and natural areas. Elcon provided a full high-Level of Development (LOD) electrical design, including power and control cabinets, lighting, standby generation, raceway routing, circuiting, cable and conduit schedules, panel schedules, load calculations, and details and schematics, in a fully coordinated Revit model.
