CITY OF LONDON WASTEWATER TREATMENT OPERATIONS ENVIRONMENTAL & ENGINEERING SERVICES DEPARTMENT 2013 ANNUAL REPORT ADELAIDE WASTEWATER TREATMENT PLANT FEBRUARY 2014

Adelaide Wastewater Treatment Plant 2013 Annual Report February 2014 SUMMARY This annual report is in response to requirements under Ministry of the Environment Certificate of Approval No. 7397-96SPH7 for the Adelaide Wastewater Treatment Plant. (a) A summary and interpretation of all monitoring data and a comparison to the effluent limits outlined in Condition 7, including an overview of the success and adequacy of the works; The annual average flow for the Adelaide Wastewater Treatment Plant was 25,813 cubic metres per day or 87% of the rated capacity of section 2. The daily average peak flow in 2013 was 61,922 cubic metres per day on September 20, 2013. Section #1 has remained shut down since 1997 but is used to provide primary treatment for peak flows and the approved peak rate for section 2 is 59,200 cubic metres per day. The rainfall for September 20, 2013 was 69 mm which was greater than the monthly average for 2012. The Ministry of the Environment guideline F5-5 recommends treating as much sewage as possible in the treatment plant prior to bypassing. There were no compliance excursions of concentrations or loadings for BOD, suspended solids, total phosphorous, E. Coli or ammonia in 2013. There has been one compliance excursions in the past twelve years. The works at the Adelaide Wastewater Treatment Plant are sufficient to meet requirements. The goals of a Pollution Prevention and Control Plan (PPCP) are to outline the nature, cause and extent of pollution problems, examine alternatives and propose remedial measures for reducing and mitigating pollution from sewer overflows and then recommend an implementation program for achieving those goals. The City of London has contracted engineering consulting firm CH2M HILL Canada Limited in 2012 to develop the plan through a detailed analysis of the impacts of rainfall events on our existing sewer systems and the Thames River. The project is in Phase 1 of the class Environmental Assessment. All sampling and analyse exceeded the requirements in the Certificate of Approval in 2013 except for the raw wastewater sample from October 28, 2013 for TKN when there was a malfunction of the digester in the Laboratory. (b) A description of any operating problems encountered and corrective action taken. Precipitation levels in 2013 were greater than average at 1,075 mm compared to 975 mm yearly average for rainfall from 1986 to 2013. No issues at the plant. (c) A summary of all maintenance carried out on any major structure, equipment, apparatus, mechanism or thing forming part of the Works; The Work Order list for the Adelaide Wastewater Treatment Plant is attached near the end of the report. Sewage is being directed to the Adelaide Wastewater Treatment Plant from the Medway Page 1 of 65

pumping station to equalize flow over the day and to help the bacteria thrive during the normal diurnal low flow (food) periods. (d) A summary of any effluent quality assurance or control measures undertaken in the reporting period; A Plant and effluent monitoring program was conducted and the data is in the tables of this report. (e) A summary of the calibration and maintenance carried out on all effluent monitoring equipment; Flow meter calibrations are attached near the end of the report. (f) A description of efforts made and results achieved in meeting the Effluent Objectives of Condition 6; The Adelaide Wastewater Treatment Plant monthly concentration and loading objectives for BOD, E. Coli, total phosphorous and un-ionized ammonia were achieved 100% of the time in 2013. The suspended solids concentration objective was achieved 83% of the time in 2013 and the suspended solids loading objective was achieved 100% of the time in 2013. (g) A tabulation of the volume of sludge generated in the reporting period, an outline of anticipated volumes to be generated in the next reporting period and a summary of the locations to where the sludge was disposed. Sludge generated at the Adelaide Wastewater Treatment Plant had an average solids concentration of 3.86%. Total sludge hauled to Greenway Pollution Control Centre for incineration was 92,189 cubic metres for a total of 3,554 dry tonnes. The primary sludge was 44,099 cubic metres at 3.2% solids and the thickened waste activated sludge was 48,090 cubic metres at 4.4% solids in 2013. The City of London will continue to haul sludge to Greenway for dewatering and incineration. The 2014 sludge volume for the Adelaide Wastewater Treatment Plant is expected to be similar to the 2013 level. (h) A summary of any complaints received during the reporting period and any steps taken to address the complaints; There were no odour complaints in 2013. (i) A summary of all By-pass, spill or abnormal discharge events. There were no raw bypass events at the Adelaide Wastewater Treatment Plant and there were five secondary treatment by-pass events in 2013. Section #1 was used to provide primary treatment for bypass flows. The total volume of primary treated effluent was 46.965 ML. Fully treated effluent was 99.5% of the flow into the plant. Rainfall in 2013 was higher than average. April 9 to 12, 2013 had 72 mm rainfall and September 20 21 had 107 mm rainfall. The two time periods accounted for over 98% of the secondary bypasses (primary treated) in 2013 at the Adelaide Wastewater Treatment Plant. Page 2 of 65
