Section 1.0 The Facility The Collingwood WWTP, owned and operated by the Town of Collingwood, is a conventional activated sludge plant with alum addition for phosphorus removal. Treated effluent from the plant is discharged to Collingwood Harbour, which is situated in Georgian Bay on the south shore of Nottawasaga Bay. The plant is located at the northern limit of Birch Street in Collingwood. The plant was first constructed in 1958 to provide primary treatment of the Town's domestic and industrial wastewater. The primary plant was expanded in 1968. Secondary treatment was added in 1981. The rated flow capacity is 24,548 m3 /day with a peak flow rate of 60,900 m3/day. Wastewater from the serviced area flows to the plant by gravity, although seven (7) pumping stations at Minnesota Street, St. Clair Street, Paterson Street, Cranberry Trail, Black Ash Creek, Pretty River Estates and Silver Glen boost the flow throughout the area. Major unit operations at the Collingwood WWTP include the following:

Headworks - provides the following preliminary process treatments: o Emergency plant bypass o Automated mechanical raked raw sewage screen o Manual raked bypass raw sewage screen o Raw sewage pumping station o Grit removal o Bio scrubber for headwork’s odour control o Septic/leachate handling

f. Only those monitoring results collected during the corresponding time period shall be used in calculating the Annual Average Concentration/Monthly Average Concentration/Annual Average Loading for this Certificate.

Monitoring results for 2016 are summarized in Appendix B.

A summary of compliance is listed below:

The annual average effluent concentrations for CBOD5, and TP fell within the applicable objectives.

The monthly average effluent concentrations for TP fell within the applicable objective.

The annual average effluent concentrations for CBOD5, and TSS fell within the applicable compliance limit.

The monthly average effluent concentration for TP fell within the applicable compliance limit.

The annual average effluent loadings for CBOD5, TSS, and TP, all fell within the applicable compliance limits.

The pH values have fallen within the 6.0 to 9.5 range permitted under the certificate.

The monthly geometric mean densities of E-Coli bacteria in the final effluent met the compliance criteria for all months.

The monthly geometric mean densities of E-Coli bacteria in the final effluent met the objective criteria for all months except January.

2.2 Effluent Sampling Requirements Monitoring & Reporting 1.0 Compliance Testing and Analysis Monitoring requirements are specified under Condition 9 (3) of the C of A. Twenty-four (24) hour composite samples of raw sewage are required to be collected quarterly and analyzed for CBOD5, TSS, TP and TKN. Twenty–four (24) hour composite samples of final effluent are required to be collected monthly and analyzed for CBOD5, TSS. Twenty–four (24) hour composite samples of final effluent are required to be collected weekly and analyzed for TP and total ammonia nitrogen. Grab samples of final effluent are required to be collected weekly for analysis for E-Coli bacteria. Lastly, the temperature and pH of the final effluent is required to be tested three times each week. The plant’s current regular monitoring program exceeds these minimum requirements. Compliance sampling and analysis of raw sewage is carried out quarterly. Twenty–four (24) hour composite samples are collected using an automatic sampler for analysis of CBOD5, TSS, TP and TKN. Compliance sampling and analysis of final effluent is carried out weekly. Twenty–four (24) hour composite samples are collected using a refrigerated automatic sampler for analysis of CBOD5, TSS, TP, and TKN, total ammonia nitrogen, nitrite and nitrate. Grab samples of final effluent are also collected weekly for analysis of E.Coli bacteria. Lastly, grab samples are collected daily (Monday to Friday) and tested for pH and temperature. With the exception of the samples collected for pH and temperature testing, analysis for all compliance samples is carried out by our external contract laboratory, ALS Environmental Laboratory, in Waterloo, Ontario.


The plant also complies with Guideline F-10-1 concerning sampling and analysis requirements which satisfies Condition 9 (4) (a). The temperature and pH of the final effluent is taken in the field at the time of sampling for Total Ammonia Nitrogen so as we can calculate the concentration of un-ionized ammonia as set out in Condition 9 (5). The Collingwood WWTP external sampling program is attached as Appendix A – WWTP Sampling Program. All external laboratory analysis results are reported in the R1 and R2 Municipal Utility Monitoring forms which are submitted electronically to the Barrie District Office and are used in generating the annual plant performance report. 2.0 In-House Testing and Analysis for Process Control Twenty–four (24) hour composite samples are collected Monday through Friday on influent, primary effluent and final effluent. Grab samples are also obtained for other process streams as required for process control purposes. All samples are analyzed on-site using standard method techniques or using approved methods for HACH DR/2010 Spectrophotometer. The Collingwood WWTP internal sampling program is attached as Appendix A – WWTP Sampling Program. Samples are analyzed using procedures from the most current edition of Standard Methods or HACH DR/2010 spectrophotometer methods. The time and day of the samples is determined by the Laboratory Technician so as to equalize the workload while maintaining representative operations data. The Technician is responsible for obtaining proper and sufficient samples through co-ordination with the process operators. 3.0 Flow Measurement Flows at the Collingwood WWTP are continuously measured at the raw sewage pumps and at the final effluent weir.

Raw sewage flows are monitored by ultrasonic flow measuring devices on pumps 1 and 3 and an electromagnetic device (magmeter) on pump 2. All devices are installed on the discharge side of the pumps.

Final effluent flows are continuously monitored by means of rectangular weir with an ultrasonic flow monitor.

A 24-hour chart recorder records the final effluent flow.

Both the influent and final effluent flows are trended through the SCADA system.

The meters are calibrated annually for accuracy (must be +/- 15%of flow rate) to satisfy Condition 9 (7) of the C of A.

2.3 Capacity Assessment The Certificate of Approval specifies that the plant is rated to treat an average daily flow of 24,548 m3/d and a peak flow of 60,900 m3/d.

Design Current Year

ADF in m3/d 24,548 16,879

Maximum daily flow in m3/d 60,900 60,310*

The annual average daily flow has fallen within these limits for this reporting period. *The peak single day max daily design flow was exceeded; approximately 50,000m3 was bypassed during an extreme weather event in addition to the max daily design flow that went through the plant. The annual average performance data is summarized in Appendix B.

Section 3.0 Biosolids Management The WWTP currently stabilizes its biosolids (sludge) through anaerobic digestion comprised of two (2) primary digesters, each with a capacity of 1,223m3, one (1) secondary digester for separation of digested sludge and collection and storage of gas, with a capacity of 1,223m3 and one (1) sludge holding tank with continuous air supply and a capacity of 990m3. A waste gas burner with a rated capacity of 560m3/hr is connected to the system. Stabilized biosolids are spread on licensed agricultural land as a nutrient and soil conditioner. Sludge produced at the Collingwood WWTP meets the quality criteria specified in the Ontario Guidelines for Sewage Sludge Utilization on Agricultural Lands. Sludge is applied in accordance with these guidelines and the conditions set out in the site Certificate of Approvals. Sludge disposal through direct utilization on land is not practical during winter months, during periods of inclement weather and when agricultural fields are inaccessible. The provincial guidelines for biosolids utilization on land recommends municipalities provide 6 months sludge storage facilities. The Town of Collingwood currently owns & operates a 5,000 m3 STF located on Part Lot 48, Concession 12 in the Town of Collingwood and contracts two 6,800 m3 STF from Region of Huronia Environmental Services Ltd. to achieve this guideline. Sludge disposal operations are currently contracted to a private hauler, Region of Huronia Environmental Services Limited, R. R. #1, New Lowell, Ontario, L0M 1N0 A total volume of 26,303.4m3 of biosolids was disposed of from the Collingwood facility in 2016. Samples of anaerobic sludge are collected twice monthly and sent for metals, E.coli, and nutrient analysis to ALS Environmental, Waterloo, Ontario, N2V 2C5. Appendix C provides a detailed summary report of sites utilized for sludge disposal in 2016. Original reporting analysis is available at the plant for viewing.


Section 4.0 Bypass Occurrences

There was one bypass occurrence during this reporting period on March 28, 2016 due to an extreme weather event. Flow to the plant went beyond the peak capacity of 60,900 m3/d. This was due to extreme weather condition which saw a high amount of snow melt and rain water reach the WWTP. Approximately 50,000 m3 was bypassed directly to Georgian Bay. The WWTP ORO contacted the Ministry of Environment and Climate Change, Spills Action and the Ministry of Health as required and provided a detailed summary of the event. A summary of the event is attached as Appendix D.

Section 5.0 Maintenance A record log is kept for each piece of equipment at the Collingwood WWTP. These logs are available for inspection at the plant. In 2016, we continued with the Continuous Service Program performed by Ainsworth Electric Co. Limited. This program utilizes such tools as thermography, voltage, load and harmonic checks, vibrations analysis etc. and has been designed using predictive and preventative maintenance to increase safety, reduce down time, reduce maintenance costs, protect asset value and extend equipment life. Regarding electrical inspections, the WWTP and seven pumping stations are being reviewed under the Electrical Safety Authority. The associated logbook at the site is available for review. All boiler and pressure vessels were inspected by personnel from the Boiler Inspection and Insurance Company of Canada. Signs of small leakage in the heat exchanger were noted and a full boiler re-tube was performed. The boiler was placed back into service with minimal downtime with no effect on plant performance. All primary and secondary clarifiers were taken out of service for inspection and repairs implemented as required (e.g. damaged flights replaced, drive chains changed, etc.). UV lamps on the disinfection system were changed out before the 5000 hour limit. Yearly inspection/maintenance was performed by Toromont CAT on standby power equipment at the main plant and all pumping stations. Gas monitoring equipment was calibrated and serviced as original equipment manufacturer’s recommendation.

Section 6.0 Complaints

The report below outlines each complaint received in 2016. The documented versions of these complaints are held at the Collingwood WWTP and are available for review on request.


Date Complaint Action/Observations

Section 7.0 Other Projects

WWTP Expansion/Upgrade

Conestoga Rovers and Associates (CRA) (now operating as GHD Canada) completed a Class Environmental Assessment (Class EA) related to the next expansion phase for the Collingwood Wastewater Treatment Plant in May 2011. The Class EA was initiated at a time when treatment flows were close to 80% of the WWTP average day capacity. The Class EA selected a preferred expansion concept that included maintaining the current conventional activated sludge treatment process, and an expansion utilizing compact secondary and tertiary technology with the ability for phased implementation. With the completion of infiltration/inflow improvements in the collection system and the loss of industry demands in the Town, current flows indicate an expansion is not required in the near future. In 2016, the WWTP ADF was operating at 69% of design ADF.

Cogeneration/ Odour Control Following the completion of a feasibility study on economic and technical options for using the digester gas, the Town decided to move forward with the installation of a co-generation plant. A micro turbine will use digester gas to create electricity which will be fed back into the plant behind the hydro meter, reducing the amount of electricity needed at the WWTP. This project will reduce the carbon footprint of the WWTP and is a beneficial way to utilize digester gas that is produced from the treatment process. Included in the project is the installation of a cover over the primary clarifiers and the installation of a gas conditioning skid to treat gas released during the transfer of digested sludge. This combined project received approval in 2016 for Small Communities Funding, a funding partnership between the Government of Canada, the Province of Ontario and the Town of Collingwood. Construction of the co-generation and odour control systems commenced in July 2016. The project is expected to be commissioned by August 2017.

EPS OXI-G Unit Installation The WWTP received a minimal amount of odour complaints in 2016. Odour control at the WWTP will be further improved in 2017 following the installation of an OXI-G unit in the headworks building. This revolutionary and proprietary unit will be installed in the headworks building and will operate in conjunction with the existing bioscrubber. This unit oxidizes chemicals in the gas stream, converting ambient air into pure ozone and hydroxide radicals. The unit will remove odours with a predicted 99% efficiency. The installation of this Canadian design in Collingwood will be the first full scale application of this product.

2017 Capital Improvement Projects

A number of improvement projects will be advanced in 2017. The following projects have been included in the 2017 budget:

Feasibility study on the options for UV unit replacement.


Engineering design and commence construction of upgrades at the Black Ash Creek & Minnesota Sewage Pump Stations, as identified through the asset management plan.

Purchase and installation of variable frequency drives on pump motors for increased efficiency.

Completion of design specifications for the replacement of existing brick facades.
