Revision History Date Revision# Revision Notes 02/26/2026 0 Report Issued Report Availability This summary report for the Richmond Community Drinking Water System (DWS) is published in accordance with Schedule 22 of Ontario's Drinking Water Systems Regulation for the reporting period of January 1"to December 31St, 2025.This system does not serve more than 10,000 residence and the annual reports will be available to residents at the Municipal Office as well as on the municipal website. Notification will be at the Municipal Office and copies provided free of charge if requested. This report was prepared by the Ontario Clean Water Agency on behalf of the Municipality of Bayham and must be supplied to the Bayham Municipal Council by March 31, 2026. System Process Description Source Water and Wells Three (3) production wells are connected to the system: one bedrock well (TW1-10) and two overburden wells (TW2-12 and TW3-12). Under normal operation, one overburden well operates at a time.The bedrock well is maintained but is not typically used due to aesthetic concerns. All three wells are classified by the Ministry as Groundwater Under the Direct Influence of Surface Water(GUDI) without effective in-situ filtration. Treatment Process Raw water from the wells enters the treatment building through separate piping for the bedrock and overburden sources and then combines into a common raw water header. Due to elevated nitrate levels in the overburden wells,treatment includes water softening and nitrate removal using ion exchange prior to storage.A nitrate analyzer on the common raw water header is used to monitor treatment effectiveness and support operational control. Primary disinfection is achieved using ultraviolet(UV) disinfection and sodium hypochlorite,which is dosed upstream of the storage tanks to provide adequate contact time.Treated water is conveyed to two on-ground storage tanks, one equipped with a top spray bar for aeration and the other with a bottom discharge connection. High-lift booster pumps draw water from storage and convey it through the treatment process. Prior to UV disinfection, water passes through parallel cartridge filters to provide equivalent in-situ filtration. Secondary disinfection is maintained using sodium hypochlorite downstream of the UV system to preserve a disinfectant residual throughout the distribution system Ontario Clean Water Agency—Richmond Community Drinking Water System—2025 Annual Water Reports Treatment Chemicals used during the reporting year Sodium hypochlorite is used to achieve Primary and Secondary disinfection in the Richmond Community Drinking Water System. Refer to Table 2 for treatment chemical supplier information of which are NSF60 approved for use in drinking water. Table 2. Treatment Chemicals utilized at Richmond Community DWS Chemical Name Use Supplier Sodium Hypochlorite Disinfection Nevtro Sales Compliance The Richmond Community DWS was operated and maintained in such a manner that treated water supplied to the consumers serviced by the system satisfied the Ontario Drinking Water Quality Standards. On January 1St, 2026 OCWA began operating the Richmond Community Drinking Water System. Notification was provided to the MECP on November 25th, 2025. OCWA was granted limited scope transitional accreditation on December 41h, 2025 and will be seeking full scope accreditation in 2026. Table 3.

Non-Compliance Identified in a Ministry Inspection The annual routine inspection of the Richmond Community Drinking Water System occurred on January 51", 2026, and was conducted by Provincial Officer,Jim Miller of the Ministry of the Environment, Conservation and Parks (MECP). The final report has not yet been received. The routine MECP Inspections have an Inspection Rating Record, which evaluates the system to provide information for the owner/operator on areas that need to be improved. The particular areas that were evaluated for the Richmond Community Drinking Water Supply System were: Treatment Process, Operations Manuals, Logbooks, Certification and Training,Water Quality Monitoring, and Reporting and Corrective Actions. There were no issues or concerns to report in 2025 that required corrective action for the Richmond Community Drinking Water System.

Ontario Clean Water Agency—Richmond Community Drinking Water System—2025 Annual Water Reports Major Maintenance Summary Distribution Maintenance Table 7:Maintenance Details - Hydrant flushing - Valve turning - Flow meter calibrations - Operating: $106,234 Flows Raw/Treated Water Flows The Richmond Community DWS is categorized as a Small Municipal Residential Drinking Water System. The system is supplied by groundwater from three municipal wells and provides treated water to consumers within the Village of Richmond. The Richmond Community DWS operated in accordance with the Municipal Drinking Water Licence 061- 102 and Drinking Water Works Permit 061-202. In accordance with Schedule 22-2(3) below is a summary and discussion of the quantity of water supplied during the reporting period. The water that is treated is regulated under the Municipal Drinking Water Licence#061-102, in which the rated capacity for the system is 43.2m3/d. The Richmond Community Drinking Water System East Train is operating at 36.5%and the West Train is operating at 39.2%of the rated capacity. The raw and treated flows are one in the same as there are only the two treated water flowmeters for each train. Refer to Figure 1 for the average daily flow each month.
