Project Overview
The Challenge
This project included the final design and supply of the electrical and control systems for five pump stations that connect the Ridgefield, WA, wastewater system with the Clark Regional WWTP in Salmon Creek, WA. The five pump stations include pumps from 7½ HP to 200 HP, all of which are VFD-controlled. The 200 HP VFDs at the 209th Street pump station are 18-pulse drives.
This was a public bid project based on typical pump station drawings that had been modified with notes to include the intent of operation for each individual pump station.
Our Approach
The Solution
Industrial Systems completed the detail design of the PLC and VFD control system for each pump station and provided the VFDs, control panels, and radio communication equipment.
Three of the pump stations were retrofits and two were new construction. The control system and VFDs of one pump station were rebuilt in the field using Industrial Systems' design and oversight, while the other four control panels were built new.
Results
Project Outcomes
Each pump station includes hardwired float control backup and pump station overflow alarm for redundancy. All pump stations communicate to the Clark Regional Wastewater SCADA system via Ethernet radio, providing integrated monitoring across the entire corridor.
