Reports on untreated sewage

These incidents are usually caused by a disruption in our sewer system. Some examples of a disruption include a broken pipe, a water main break or a power outage. When sewer operations are disrupted, sewage may be released into the environment.

We report every incident to the Province of Manitoba.

Feb. 8 900 mm wastewater overflow outfall & 800 mm wastewater river crossing pipe located at 3100 Abinojii Mikanah (Bishop Grandin) 10.8 megalitres Approx. 15 hours plus (ongoing at time of report) Pipe leak
Incident details and response
  • At approximately 9 a.m. on February 7, 2024, operations staff were reviewing the data from the flow monitoring device located in the Fort Garry river crossing pipe outlet chamber and noticed an anomaly. A maintenance crew was dispatched to investigate.
  • The maintenance crew arrived around 10 a.m. They found a sinkhole over the 800mm sewage pipe on the west side of the Red River. The maintenance crew observed sewage in the sinkhole, indicating a pipe leak.
  • Around 10:15 a.m., the crew opened the 900mm overflow outfall slide gate to relieve the pressure in the 800mm pipe. A maintenance crew remained on site to monitor the sinkhole and pipe chambers.
  • The Water and Waste Department had already hired a contractor to install an emergency bypass pumping system (see November 30, 2023 report on untreated sewage for more info). The bypass pumping system will take sewage from upstream of the D’Arcy Pumping Station, bypass the D’Arcy Pumping Station and the 800 mm pipe, and discharge it into the chamber located on the east side of the Red River.
  • The 800mm pipe is still passing some of the flow through the D’Arcy Pumping Station for treatment, however, the remainder of the flow from the D’Arcy Pumping Station is discharging to the Red River from the leak in the 800mm pipe and the 900mm overflow outfall.
  • Once the emergency bypass pumping system is installed and operational, the sewage discharge will stop, and the 800mm pipe will be permanently abandoned. The bypass pumping system will remain in place until new river crossing pipes can be permanently installed and connected to the D’Arcy Pumping Station.
  • The estimated volume of sewage discharged to the Red River between 9 a.m. on February 7 and 12 a.m. on February 8 is 10.8 megalitres.
  • The incident was reported to the Manitoba Environment and Climate Change Accident Reporting line Wednesday, February 7, 2024.
Jan. 12 1800 mm combined sewer outfall located at 200 Syndicate Street 0.003 megalitres Approx. 9 minutes Sensor failure
Incident details and response
  • On January 12, 2024 at 12:39 a.m., our Wastewater Control Center received a wet-well level sensor fail alarm at the Syndicate Wastewater Lift Station. Our station instrumentation indicated that an overflow started at 1:12 a.m. A standby maintenance crew was called in to attend. They were able to manually start the station pumps to stop the overflow at 1:21 a.m.
  • At 3:02 a.m., an instrumentation technician was called in to investigate the cause of the level sensor failure. The technician found some loose wires in the control panel, which he secured. The crew remained on site overnight to monitor the performance of the pumping station and noticed no further issues.
  • Later that morning, a technician checked the level sensor again and concluded that there was no issue with the sensor. The Wastewater Control Center will continue to monitor this station.
  • The estimated volume of wastewater discharged to the Red River is 0.003 megalitres.
  • The incident was reported to the Manitoba Environment and Climate Change Accident Reporting line Friday, January 12, 2024.
Jan. 7 250 mm combined sewer outfall located at 63 Shier Drive 0.50 megalitres Approx. 11 hours, based on the time of the 311 call Water main break
Incident details and response
  • On January 6, 2024, at 2:15 p.m., our Wastewater Control Center received notification from our 311 Call Centre that there may be wastewater discharging from an outfall at 63 Shier Drive. A stand-by maintenance crew was dispatched to investigate. They found a blockage in the sewer on Barker Boulevard. This blockage caused wastewater to back up in the system and overflow to the Assiniboine River through the high-level overflow pipe located at 63 Shier Drive. A vacuum cleaning unit was called in to clear the blockage. At 1:15 a.m. on January 7, the blockage was cleared and the overflow had stopped.
  • The 311 Call Centre was notified of the discharge by a local resident. The resident noticed what they believed to be wastewater flowing from the overflow pipe around December 30, 2023 while walking along shoreline of the river.
  • A review of instrumentation data from the Barker pumping station indicates that the sewer was only partially blocked on Barker Boulevard and that the overflow was only occurring during times of high flows in the local wastewater system.
  • The estimated volume of wastewater discharged to the Assiniboine River is 0.50 megalitres, (from December 30, 2023, as reported by the resident).
  • The incident was reported to the Manitoba Environment and Climate Change Accident Reporting line Saturday, January 6, 2024.
