Wastewater Treatment Plant (WWTP)

Share on Facebook Share on Twitter Share on Linkedin Email this link

The City's sanitary sewer collection system and Wastewater Treatment Plant was designed for, and now has, a contributing population of approximately 20,000 people. The collection system flows to the South Lift Station at the south end of the City and then flows to the City’s Wastewater Treatment Plant, approximately 1.5 km to the southeast.

With the existing facilities close to capacity, an expansion is required to accommodate the additional flows and loads. A contributing population approximately 30,000 people is currently forecast for around 2035. Additionally, our Alberta Environment and Protection (AEP) approval includes requirements for system upgrades to accommodate both the projected population growth and to achieve significantly increased treatment standards to reduce the impact on the receiving waters.

The proposed $42.2 million upgrades are intended to meet requirements for additional capacity and the need for higher treatment standards driven by regulations. This upgraded plant will provide cleaner water back into the watershed and give our community room to grow.

    On December 21, 2023, the Waste Water Treatment Plant Project was officially given the green light on substantial completion for the main treatment upgrades to the aerated lagoons, Moving Bed Biofilm Reactor (MBBR) tanks and process building.

    As of that day the City took over full responsibility for the day-to-day operations and maintenance of these facilities which also started the two year warranty period for those major facilities and processes.

    “Maple Reinders Constructors (MRCL) is still on site, and will continue working on various upgrades within the South Lift Station and in the old blower building, which is being converted to a storage/workshop facility for staff,” explained City of Camrose Engineering Services manager Jeremy Enarson. “MRCL will also continue to be working in the Process Building on clean-up of various deficiencies. But the keys have effectively been handed over to the City for the main treatment and storage facilities.”

    In a report to City council on January 22, Enarson presented a complete update of the Wastewater Treatment Plant Construction and Landfill Clay Purchase projects.

    “As part of the ongoing operations, Administration continues to test the wastewater on a regular basis to confirm if the WWTP is meeting the treatment requirements, as required by the provincial and federal regulators,” noted Enarson.

    “These test results are being shared with MRCL, as they have an ongoing requirement within the contract to assist the City with optimizing the treatment process until the project is fully complete in the spring of 2024.”

    Enarson reported that, based on the test results, Administration and AE note that most of the required treatment parameters are meeting the new limits outlined by the regulators, although there are still a few parameters which are not consistently meeting the new limits.

    “Under the new provincial approval, the City has until the end of June 2024 to ensure that all parameters are within the new limits without being in contravention.”

    Enarson explained that due to the extreme cold temperatures in mid-January, the WWTP experienced a number of operational issues in particular related to the MBBR tanks.

    “The treatment processes appears to have functioned relatively well during the cold temperatures. However, the extreme cold resulted in ice buildup within the MBBR structure.

    “Administration worked with AE and with MRCL to identify some short term options for keeping water flowing through the MBBR tanks, as well as some longer-term options to ensure that the MBBR process functions during future cold weather events.”

    Enarson gave kudos to the operational and maintenance staff during this bout of cold weather for putting in extra time and effort to keep things operating.

    Financial Status

    According to Enarson’s report, the City has spent over $47,254,000 to date on the WWTP project. At this time, the City is expecting the final cost for the WWTP project to be around $49,396,000, which is below the approved budget of $51,170,000.

    “The City has already spent over $300,000 on costs that are outside of MRCL or AE’s scope, and will spend approximately another $150,000 on additional out-of-scope costs before the project is complete.”

    He explained that these costs include the purchase of items for the WWTP, such as, computer hardware and software for monitoring the various wastewater treatment processes and equipment, the initial purchase of chemicals for the operations of the WWTP, a forklift for moving around equipment and chemicals within the Process Building, as well as tools and other equipment that City staff will need in the operation of the new facilities, including in the new laboratory.

    “In addition, the City has charged over $200,000 to date for City staff and equipment costs for work directly related to the WWTP project. This amount is expected to be around $270,000 once all City costs are allocated to the project for 2023 and 2024. All remaining expenses will be charged to the WWTP project by the end of 2024.”

    As noted in the report and earlier reports to council, all of the work on the Landfill Clay Purchase Project is complete.

    Council Inquiries

    Councillor Joy-Anne Murphy asked for more information about planning for any future weather anomalies and whether there was any damage to the WWTP as a result of the recent cold weather.

    Enarson replied, “The MMBR process is designed to function in an open air environment in cold temperatures. It should continue to function from a treatment perspective in those cold temperatures.

    “The issue we received on site was that in those cold temperatures we were getting a lot of icing,” explained Enarson adding that Administration was advised by the contractor on what can be done in the event of future extreme cold temperatures.

    “One of the deliverables we need from the consultants is input on our standard operating standards–giving advice on how we should run this, making sure operators not only understand the theory behind the technology but also advice on how to run the facility as we get into winter months. What they suggest on making changes in terms of how to flow liquid through the processes so it gives us greater success when we do get into the cold events in the future.”

    City of Camrose manager Malcolm Boyd added that because this is a brand new process for the City, with no winter experience yet, it is more about optimizing the processes not insulating or putting a roof on the MMBR tanks.

    In conclusion, Enarson indicated that Administration is exploring the idea of hosting open houses and tours for public, including schools and other organizations interested in how the system operates, and what can be done at the facility to add to that experience.

      • All work related to the Landfill Clay Purchase project (project #1020) is complete.
      • The original contract work related to the storage lagoons is complete.
      • Administration is in discussions with MRCL and the City’s consultant (Associated Engineering) about a few additional upgrades related to the storage lagoons which were not part of MRCL’s original scope. This includes a further upgrade to the outlet structure for Cell I, as well as the possible cleaning of storage Cell H.
    4. Final landscaping, construction of parking lot and trail access, etc.
      • All work related to this scope is complete, with the exception of some minor cleanup work to be completed in the spring.
    5. General requirements
      • Ongoing payments as outlined in the General Requirements portion of the contract.

    Summary of Upcoming Work

    The following is a summary of the main activities that will occur, as well as the anticipated timelines for each activity. Administration has organized this summary using the same categories as noted above:


    In summary, MRCL’s work on the WWTP project will be largely complete by the end of January in all of the major facilities. Under the contract, MRCL is supposed to complete all work by the end of March 2024. At this time, Administration expects that MRCL will meet that deadline, although Administration has agreed to allow MRCL to leave some storage trailers on site until the spring. However, as noted below, the City is currently working with AE and MRCL on some potential change orders that might extend MRCL’s work until later in 2024.


    Current Financial Status of Projects, including Approved Scope Changes

    The following is a summary of the approved budgets and current / projected spending for the WWTP and landfill clay purchase projects.

    As noted in the following tables, the City has spent over $47,254,000 on the WWTP project to date. The majority of these costs were paid to the general contractor (MRCL) or to the project consultant (AE). However, the City has already spent over $300,000 on costs that are outside of MRCL or AE’s scope, and will spend another ~$150,000 on additional out-of-scope costs before the project is complete. These costs include the purchase of such items as equipment for the WWTP laboratory, computer hardware and software for monitoring the various wastewater treatment processes and equipment, the initial purchase of chemicals for the operations of the WWTP, a forklift for moving around equipment and chemicals within the Process Building, as well as tools and other equipment that City staff will need in the operation of the new facilities. In addition, the City has charged over $200,000 to date for City staff and equipment costs to date for work directly related to the WWTP project; this amount is expected to be around $270,000 once all staff costs are allocated to the project for 2023 and 2024. All remaining expenses will be charged to the WWTP project by the end of 2024.

    The Camrose Regional Solid Waste Authority (CRSWA) – for which the City acts as Administrator – spent over $1,551,000 on the Landfill Clay Purchase project. The full amount has been funded by the City of Camrose. As this project is now complete, all remaining invoices from MRCL or from AE will be billed entirely to the WWTP Upgrade project. All costs for the Landfill Clay Purchase project have been recorded as inventory and have not been expensed at this time. Once the clay is utilized for future landfill projects, the inventory used will be expensed and funded by the landfill closure liability maintained by the CRSWA.


    The next planned Council update for this project will be in April 2024. Full details from this recent update to Council can be found in the January 22, 2024, Committee of the Whole Agenda.

  • Expanded Emergency Overflow Ponds Now Functional

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    The new, expanded Emergency Overflow Pond is now functional, doubling our storage capacity of waste from 7,000 cubic meters to 14,000 cubic meters. The new Overflow Pond is just South of the existing pond and acts as another layer of protection to our water way.

    The Emergency Overflow Pond reduces the risk of untreated waste flowing into the Stoney Creek during a major storm event.

    Our South Lift Station is a small building but major player in our waste water treatment system. It breaks down and then pumps waste water from the City up to the lagoons to be treated. A major storm may cause flow rates that are faster than the South Lift Station can pump, so the Overflow Ponds capture that flow until a time that the water can be processed and pumped through the South Lift Station.

    The Ponds may contain waste water during or following a major storm event so we ask the public to avoid the ponds and to not let pets drink from the ponds. This is just one way our new Waste Water Treatment Plant upgrade is protecting the Stoney Creek, and the overall Battle River Watershed, today and how we are doing our part to ensure we have clean drinking water for future generations.

  • MBBR Media Added

    The unloading of the final batches of "Moving Bed Biofilm Reactor" (MBBR) media will be completed soon! As a crucial component of the MBBR process, the City will have approximately 630 million of these small plastic discs, also known as MBBR media, housed within large concrete tanks. Bacteria will grow on the MBBR media, and these bacteria will consume the ammonia in the City’s wastewater as part of the treatment process.

    Summary of Upcoming Work

    Based on MRCL’s latest work plan, the following is a summary of the main activities that will occur, as well as the anticipated timelines for each activity. Administration has organized this summary using the same categories as noted above:

    All work related to the Landfill Clay Purchase project is effectively complete. MRCL will continue to move clay in/out of the existing stockpile as needed for final grading at the main WWTP site.

    The WWTP upgrades are planned to be substantially complete by early November 2023, with final cleanup of work being completed in the spring of 2024. The November timeframe is slightly later than what required in the City’s contract with MRCL, which specifies a Substantial Completion date of the end of October 2023. At the last Council update, Administration noted that this date was to be late November as a result of delivery delays for major pieces of electrical equipment (the Motor Control Centres or MCCs). The MCCs were delivered to site in early July, which was about two weeks prior to the latest projection. As a result, the anticipated substantial completion date has been advanced to early November.

    The City and its consultant (Associated Engineering, AE) have been working closely with MRCL to minimize the impact of the MCC delivery delay. At this time, Administration does not anticipate any concerns related to the start-up / commissioning activities, or for ongoing performance of the WWTP at the end of this project.

    Have you noticed something in the air? The construction of the new Wastewater Treatment Plant involves completely replacing the aeration system in the treatment lagoons. A higher number of odor issues are expected this summer as we take the old system offline and put in the new system. This work is likely to take until the end of August, however, the new system will improve treatment and odor issues in the long run!

  • Dropping in the Discs (article by Lori Larsen, Camrose Booster)

    Article by Lori Larsen, Camrose Booster

    On July 6 City of Camrose Councillors Agnes Hoveland, Kevin Hycha, Lucas Banack and Don Rosland, joined City of Camrose Infrastructure General Manager Kris Johnson, Engineering Services Manager Jeremy Enarson and Engineering Services Assistant Kirsten Nichols, started the process of putting the Moving Bed Biofilm Reactor or MBBR media plastic discs into the large concrete holding tanks of the new Wastewater Treatment Plant (WWTP).

    “The main unloading of the over 630 million media will be completed by the WWTP main contractor starting in early to mid-July, continuing over the next six weeks,” explained Enarson.

    The discs are placed in the tanks as an integral part of the process to remove ammonia from the city’s wastewater.

    “The plastic discs will be circulating around in the tanks while bacteria grow on the surfaces of the discs. When the discs come in contact with the wastewater, the bacteria will digest the ammonia, therefore reducing the amount of ammonia in the city’s treated wastewater. To help speed along this process, the City will be pumping air into the wastewater using blowers, which will provide both mixing of the plastic discs, as well as the oxygen that the bacteria will need to digest the ammonia.”

    Enarson further explained why this process is vital. “The ammonia, if it gets out into the environment in high concentrations, can result in a fish kill. The result of what the City is doing with the MBBR plastic discs is lowering ammonia levels in treated wastewater, which will have less of an impact on the fish environment.”

    The other important component of the Wastewater Treatment Plant is the removal of phosphorus which occurs in the main processing building.

    “While phosphorus is not immediately toxic to fish, phosphorus and other nutrients can be released into the environment and that can lead to the algae blooms that you see on lakes which depletes the oxygen levels and that can kill fish over time. By removing phosphorus from the City’s wastewater, we are also improving the quality of what is released back to the environment.”

    Upgrades to the City of Camrose Wastewater Treatment Plant began in 2021 with an expected timeline of completion in early 2024.

    The proposed $51.1 million upgrades are intended to meet requirements for additional capacity and the need for higher treatment standards driven by regulations. This upgraded plant will provide cleaner water back into the watershed and give the community room to grow.

    Pictured left to right are City of Camrose Councillors Lucas Banack and Kevin Hycha, City of Camrose Engineering Services Manager Jeremy Enarson, and Councillors Don Rosland and Agnes Hoveland doing the inaugural dropping of the MBBR plastic discs into the south MBBR holding tank of the new Wastewater Treatment Plant, on July 6.

    Summary of Upcoming Work

    Based on MRCL’s latest work plan, the following is a summary of the main activities that will occur, as well as the anticipated timelines for each activity. Administration has organized this summary using the same categories as noted above:


    All work related to the Landfill Clay Purchase project is effectively complete. MRCL will continue to move clay in/out of the stockpile as needed for final grading at the main WWTP site.

    The WWTP upgrades are planned to be substantially complete by November 2023, with final cleanup of work being completed in the spring of 2024. The November timeframe is later than what required in the City’s contract with MRCL, which specifies a Substantial Completion date of the end of October 2023. Unfortunately, this date was pushed back as a result of delivery delays for major pieces of electrical equipment (the Motor Control Centres or MCCs). The City and its consultant (Associated Engineering, AE) are working closely with MRCL to minimize the impact of this equipment delivery delay on the overall project, and to ensure that this delay will not adversely impact the start-up procedures and the ongoing performance of the WWTP at the end of this project.

    Current Financial Status of Projects, including Approved Scope Changes

    The following is a summary of the approved budgets and current / projected spending for the WWTP and landfill clay purchase projects.

    As noted in the following tables, the City has spent over $33,293,000 on the WWTP project to date. The remaining WWTP project expenses will be realized by the spring of 2024.

    As well, the Camrose Regional Solid Waste Authority – for which the City acts as Administrator – has spent over $1,551,000 on the Landfill Clay Purchase project to date. As this project is now substantially complete, any further invoices from MRCL or from the City’s consultant (AE) will be billed entirely to the WWTP Upgrade project.


    The next planned Council update for this project will be in July 2023. Full details from this recent update to Council can be found in the April 24, 2023, Committee of the Whole Agenda.
