Hauled wastewater program
The Hauled Liquid Waste Facility at the South End Sewage Treatment Plan is now closed. Please take liquid waste to the North End Sewage Treatment Plant at 2230 Main Street for disposal.
A presentation about the South End Sewage Treatment Plant (SEWPCC) hauled wastewater facility closure was given at a town hall meeting held on May 31st, 2017.
Wastewater facility closures and changes
Why did the City decide to close the disposal facilities at the South End Sewage Treatment Plant (SEWPCC) and the West End Sewage Treatment Plant (WEWPCC)?
- Having hauled wastewater at both facilities could put the new treatment process at risk:
- The bacteria in the new treatment process are sensitive to sudden changes in wastewater concentration, and will not treat the wastewater properly if they're suddenly overloaded by hauled wastewater, which is stronger than the wastewater that comes from our sewer system.
- If the bacteria can't treat the wastewater properly, then the treated wastewater that flows to the river wouldn't meet environmental standards and the treatment plants would be out of licence compliance.
- The initial plans were to keep both North End and the South End Sewage Treatment Plants (NEWPCC/SEWPCC) open and to simply upgrade their disposal facilities. However, continuing to accept hauled wastewater at the South End Sewage Treatment Plant (SEWPCC) would pose too great a risk to the sewage treatment process.
- The City was required by the provincial government to upgrade the plant to a biological nutrient removal process. This process relies on bacteria to remove the nutrients.
- For more information:
- The West End Sewage Treatment Plant (WEWPCC) facility closure please see the 2006 Council Report
- The South End Sewage Treatment Plant (SEWPCC) closure please see the 2015 'Closure of Hauled Wastewater Disposal Facility at the South End Sewage Treatment Plant' report
Will there be any impact on the treatment processes at the North End Sewage Treatment Plant with the increased volume of hauled wastewater?
- We do not anticipate an impact on the current treatment process or the future biological nutrient removal process.
- The North End Sewage Treatment Plant is four times as large as the South End Sewage Treatment Plant and the process is therefore less sensitive to a sudden change from the hauled wastewater.
What improvements have been made to hauled wastewater disposal at the North End Sewage Treatment Plant?
The Hauled Wastewater Facility at the North End Sewage Treatment Plant was expanded with an additional disposal lane to accommodate the increased traffic from haulers. Modifications were also made to improve the reliability of the facility.
What is hauled wastewater?
- a term for hauled sewage
- all matter (liquid and solid) that is pumped out of septic tanks, holding tanks and tanks/interceptors from residential or non-residential (commercial/industrial) properties
- raw and untreated
What are the different types of hauled wastewater?
There are two types:
Household hauled wastewater
- usually from residential properties not serviced by the wastewater sewer system
- means grey water and toilet waste discharged by appliances (e.g., dishwashers, washing machines) and plumbing fixtures (e.g., toilets, urinals, bidets, sinks, showers, bathtubs)
- typically two to four times more concentrated than regular sewered wastewater
Non-household hauled wastewater
- usually from commercial/industrial properties
- typically 70 to 340 times more concentrated than regular sewered wastewater
Who hauls wastewater?
- companies that have special trucks that can empty the wastewater from onsite wastewater management systems (e.g., holding tanks, septic tanks, portable toilets) and transport it to a wastewater treatment facility
Where is the wastewater hauled to?
The hauled wastewater facility at the North End Sewage Treatment Plant (NEWPCC), 2230 Main Street.
Do you have wastewater disposal stations for recreational vehicles?
Yes, we have two wastewater disposal stations open year round.
Disposal fee - Hauled Wastewater
Rates are effective January 1 of each year, unless otherwise noted
|Type of Fee||Charged to||2016||2017||2018|
|Hauled wastewater disposal fee||
|Non-household hauled wastewater fee||
*non-household hauled wastewater includes restaurant grease traps effective January 1, 2014
Why does it cost more for haulers to dispose their hauled wastewater, compared to traditional sewer rates ?
- Hauled wastewater is more concentrated than regular wastewater. The higher the concentration, the more costly the treatment.
- The rate is also used to recover the capital and operating costs of the hauled liquid waste disposal facility, located at the North End Sewage Treatment Plant.
If I'm a wastewater hauler, how do I apply for a licence?
- haulers must obtain a licence from us for each vehicle that uses our disposal stations by contacting our Industrial Waste Services Branch
- the initial licence fee is $152.00
- the annual renewal licence fee is $76.00
How much does it cost to dispose a typical residential holding tank in Winnipeg?
- A typical residential holding tank is 6.8 kilolitres in size.
- At the 2018 rate of $8.90 per kiloliter, it costs $60.52 to dispose one residential holding tank at Winnipeg's Sewage Treatment Plant(s).
- Haulers will charge additional fees to customers for transporting the waste and for their overhead costs.
How does Winnipeg's hauled wastewater fee compare to other cities?
- A survey of 2017 hauled wastewater fees across Canada shows we have one of the lowest rates in the country.
