SCADA system monitoring
Water Pollution Control Centre, the sewage treatment facility,
and wastewater collection systems. The Comox Valley water
utility includes a new water treatment plant that, after years of
planning and construction, went online in fall 2021, as well as
many distribution facilities and two other water treatment plants.
The wastewater treatment facility and wastewater collection
systems were the first CVRD facilities to integrate the new
remote alarm notification software with their existing SCADA
system. McCauley oversaw this with the assistance of Dawe and
the feedback from operations to configure servers and set up
networks.
For the community’s water treatment and distribution, the
CVRD manages three water treatment plants, five booster pump
stations, 10 reservoirs and associated facilities, and oversees 33.6
kilometres of pipe within the main service area’s transmission and
distribution system. For wastewater treatment and collections,
the CVRD manages two wastewater treatment plants, five sewage
pump stations, and 30 kilometres of sewer lines.
Each utility has its own physical server and a specific virtual
server running the remote alarm notification software, which
connects to Rockwell Automation FactoryTalk™ View SE SCADA platform.

The new water treatment plant has a raw
water pump station that pumps water
from Comox Lake. The SCADA system
monitors the level, pressure, flow,
turbidity, UVT, pH and temperature of
four-150 horsepower pumps. The main
plant also has similar instrumentation
that helps monitor and control systems
such as flash mixing, flocculation,
filtration, caustic, coagulation, chlorine,
UV disinfection, clear wells, solids
dewatering, and all of their associated
equipment. Using filtration, chlorination
and UV disinfection removes the risks
of viruses and bacteria from drinking
water and provides a secure supply of
reliable, high-quality drinking water.
The wastewater SCADA system
monitors many pieces of equipment as
well as instrumentation including level,
pressure, liquid flow, air flow, dissolved
oxygen, TSS, pH, ORP, and temperature.
All of the instrumentation helps monitor
and control systems such as headworks,
grit and sludge removal, bioreactors,
aeration, RAS, WAS, solids dewatering,
scrubbers, chemical systems, as well as
all of the sewage pump stations.
Included in the recent
upgrades are the bioreactors and treatment of
the additional odorous
air through a new,
larger wet chemical
scrubber. The Comox
Valley Water Pollution
Control Center treats
sewage (wastewater) from businesses
and residences.
