Waste Water Collection Process Control System Upgrades

Client

City of Toronto

Location

Toronto, Ontario

PROJECT DESCRIPTION

The Waste Water Collection (WWC) system provides sewage and storm water conveyance for the City of Toronto and operates 24/7/365. The existing sewage/ storm water stations required a SCADA system upgrade as the existing infrastructure no longer supported remote communication with the Toronto network. The project consisted of upgrades to the process control system at the pump stations, blower stations and retention tanks within the WWC system. The modifications implemented new Programmable Automation Controllers (PACs), Operator Interface Terminals (OITs), new instruments, new access control panels, access control instrumentation, and new WAN and LAN equipment at various locations.

B&M SCOPE OF WORK

Black & McDonald’s (B&M) scope of work included supply of materials, labour, equipment and permits necessary for the upgrade of process control systems at 83 pumping stations across Toronto including:

Installations of new PACs and OITs, power monitoring equipment, and communication equipment at all stations connected to the Toronto network
Upgrades to various instruments (pressure/flow)
Provision of new software for all pumping stations
Testing and commissioning all of the stations

New software was developed, tested and implemented by B&M in collaboration with the Project Consultant for all PACs and OITs at the remote facilities and iFIX systems at the WWC system control centre.

BENEFITS TO CLIENT OR PROBLEM(S) SOLVED

All of the Toronto stations operate continuously around the clock and require uninterrupted pumping and collections during all installs. B&M is providing bypass pumping for critical equipment ensuring no capacity is lost at any station.
