Report No.: WSC 118-2012

UTILITY MANAGEMENT COMMITTEE (UMC) RECOMMENDATION

THAT Report No. WSC 118-2012, dated November 26,2012, from Len Stein, Director of Utility Operations, regarding JAMES Plant Monthly Report - November 2012, be received.

DISCUSSION

The plant effluent quality met all regulatory parameters for effluent discharge during the month of November 2012 and was well within the regulated limits. The key plant measurement parameters discussed below are defined and tabulated in appendices A-E. Al l results are forwa rded to MoE on a quarterly and yearly basis. All non-compliance parameters are listed in the reports to MoE.

InfluenVEffluent Data (Appendix A)

This shows the daily flows and influent and effluent quality on each day of the month. The fecal coliform test gives an indication that bacteria originating from the intestines of warm blooded an imals may be present in the wastewater.

All the required fecal coliform testing for the month of November 2012 were within acceptable limits. The limit for coliforms is 200 counts per 100 ml outside the initial dilution zone. The counts recorded are end of pipe prior to dilution from the Fraser River.

Biochemical Oxygen Demand (BOD) (Appendix B)

BOD is the rate at which oxygen in wastewater is used for the decomposition of organic matter in the waste water. High BOD rates reflect high organic content in the wastewater. Treatment plant processes reduce BOD levels before discharge to the environment.

The following chart compares monthly average BODs in mg/I.

The average BOD strength in the plant effluent for the three months listed was well below the regulated limit of 45 mg/!. BOD on the influent has increased due to industrial loading and increased concentration (not being diluted from the domestic sewage from Langley).

Total Suspended Solids (TSS) (Appendix C)

Total suspended solids are the total amount of solids that remain in suspension in the water. The higher the suspended solids concentration the harder the effluent is to disinfect and the higher the Biochemical oxygen demand will be.

The following chart compares monthly averages TSS in mg/!.

The above compares the average of TSS influent and TSS effluent strength over the same time period one year previous, for three consecutive months and is well below the regulated limit of 45 mg/!. For the month of November influent TSS are still higher than last year but are returning to a more normal level over the two prev,ious months.

All tests done for the month of November were well below the toxicity curve. In recent months Ammonia has increase over the same time period last year. Ph in the effluent has also increased slightly increasing towards the toxicity curve. This can be seen in appendix E.

Appendix A

DEFINITIONS

BOD (Biochemical Oxygen Demand) is defined as the rate at which microorganisms use the oxygen in waste­water while stablizing decomposable organic matter under

aerobic conditions.

BOD Test is a procedure that measures the rate of oxygen use under controlled conditions of time and temperature. Standard test conditions include dark incubation at 20 C for a period of 5 days.

Suspended Solids (s.s.) are solids that either float on the surface and/or are suspended in water, wastewater, or other liquids, and which are largely removable by laboratory

filtering.

Ammonia N (Ammonia Nitrogen) is tested as an indicator of toxicity in the ptant effluent. General rule of thumb is that toxicity is being approached when the Ammonia N is in the 20 - 25 mg/l range if the PH is above 7.S. At that range or beyond, there is a good possibility of failing the required 96 hour LCSO Bioassay Test as outlined by Environment Canada

Fecal Coliform Test is an indicator for the presence of bacteria originating from the intestines of warm-blooded animals and their presence may be indicative of the presence of disease producing organisms that may be found with them. Zero or counts below the maximum level of 200 cotonies/100 ml sample indicates that sufficient chtorine has been used for disinfection purposes. Coliform counts are end of pipe, the regulation is oul side the initial dilution zone
