North End Sewage Treatment Plant Upgrade
- Fast Facts
The North End Sewage Treatment Plant, otherwise known as the North End Water Pollution Control Center (NEWPCC), is the City of Winnipeg's oldest and largest sewage treatment plant. First commissioned in 1937, it provides 70 per cent of the city's wastewater treatment. As part of the Winnipeg Sewage Treatment Program (WSTP), NEWPCC will undergo one of the largest, most complicated upgrade projects in North America. The WSTP approach combines science, engineering, construction, operations and project management. It focuses on lifecycle costs, which includes the cost to build, operate, and maintain the plant. The upgrade includes improved treatment plant technology to remove nutrients and to treat wet weather flows. This upgrade is also addressing nutrient reuse and recovery, through the construction of a new biosolids processing facility.
Once these nutrients are removed from the wastewater, what do we do with it?
Traditionally these nutrients have been treated with chemicals and taken to the landfill. The NEWPCC upgrade will incorporate two new technologies in the treatment process to recover and reuse the nutrients:
- Phosphorous, a non-renewable resource that is being depleted world-wide, will be recovered from the biosolids using equipment and technologies developed by Ostara. The end result of the recovery is a high value fertilizer (Crystal Green™).
- The biosolids, a key by-product of wastewater treatment, will be treated by a high-temperature thermal-hydrolysis process developed by CambiTHP. This process will result in a pathogen free biosolid that is safe to use as fertilizer. The CambiTHP process also reduces the end volume of biosolids, thus reducing transportation costs.
The plant upgrades will accommodate future growth in the catchment area as well as provide treatment during wet weather events such as snow melt or large rainstorms.
A new power substation is required at NEWPCC to meet the additional power demand of the upgrades. The power supply upgrade will be delivered as a separate project from the larger NEWPCC upgrade. This will allow for early procurement of long-lead items, like transformers, and ensure that the additional power is available when needed.
NEWPCC currently treats enough wastewater to fill 75 Olympic sized swimming pools every day.
In 2016, NEWPCC removed 1,959,600 kg of debris like sand, egg shells, floating plastics, sticks and paper, from wastewater. This is the equivalent weight of 725 full grown elephants.
The NEWPCC upgrade will include:
- a new raw sewage pump station
- a new grit and screenings (debris) building
- a biological nutrient removal reactor train with secondary clarifiers
- a new high rate clarifiers to provide wet weather flow treatment
- upgraded biosolids process, including thermal hydrolysis, digestion and struvite recovery

- Progress continues on development of a concept level design which will form the basis for the City of Winnipeg's project requirements. A number of ancillary projects and activities are underway in anticipation of the upgrade.

Frequently Asked Questions
Wet weather flow occurs with the snow melt in spring and severe rainstorms during the summer months, resulting in higher than average flows of wastewater arriving at the treatment plant. We can expect 100 wet weather events to occur each year.
- The City of Winnipeg aims to reduce Winnipeg's contribution of nitrogen and phosphorous to Lake Winnipeg.
- To meet the requirements of Manitoba Regulatory Licence.
- To accommodate future population growth.
- To replace equipment that is at the end of service life.
- Currently, NEWPCC removes approximately 1,500 kg/day on average.
- After the upgrades are complete, NEWPCC will remove approximately four times more nitrogen, an estimated 7,000 kg/day.
- Currently, NEWPCC removes approximately 500 kg/day on average from the effluent.
- After the upgrades are complete, the NEWPCC plant will remove more than double the phosphorous, an estimated 1,300 kg/day.
- The maximum flow of wastewater than can be treated each day will increase from 380 million liters per day to 705 million litres per day.
- No, NEWPCC will continue to operate during construction.
