System Overview 6
System Overview • JAMES Plant treats sewage from Abbotsford, Mission, and Sumas Washington • Secondary treatment • Discharge to Fraser River • Serves 240,000 population equivalent 7
Service Area DISTRICT OF MISSION CITY OF ABBOTSFORD 8
Primary Secondary Fraser Influent Disinfection Treatment Treatment River Schematic N Mission Flow Abby Flow JAMES WWTP (Flow) 9
Treatment Process Inflow to Plant Preliminary Secondary Fraser Treatment Primary •Abbotsford Treatment River Disinfection (Headworks Treatment •Mission (Biological) •Sumas, WA Screening) Solids So urc e Solids Treatment Dewatering Land control • Pasteurization Application • Anaerobic Digestion to prevent Centrate upsets Treatment 10
Inflow Components Residential, Inflow to Plant Industrial Commercial, •Abbotsford Institutional •Mission •Sumas, WA Wet Processors Dry Industries (Extra Strength) High load 11
Source Control To protect the sewage collection system, the treatment facilities, the biosolids quality, the receiving environment, and the health and safety of the public and sewer workers • Importance of pH • Industrial monitoring • Strength/pH 12
Upgrades Trigger (Typical) Flow Flow Flow Load Flow Inflow to Plant Preliminary Secondary Fraser Treatment Primary •Abbotsford Treatment River Disinfection (Headworks Treatment •Mission (Biological) •Sumas, WA Screening) Solids Solids Treatment Dewatering • Pasteurization Land • Anaerobic Digestion Application Centrate Treatment Load Load 13
Issues and Opportunities Extra Strength Capacity Seismic Odour Biosolids Biogas (High Load) Industries Projection 14
BOD Load Extra Strength BOD Load Total Plant BOD Load (kg/yr) (kg/yr) Extra Strength BOD Load (kg/yr) Approximately 25 Extra Strength (high load) users Six of them are contributing to the higher load (80-85% of total) Milk processor 15
Extra Strength Industrial Load Scenarios BOD (kg/d) Eq Pop 1 2016 Level 7,400 106,000 2 1.7% growth 11,000 158,000 per year Extra Strength (High Load) Industrial BOD growth could drive need for earlier plant expansion. Options - Impose Pre-treatment for new industries to certain limits - Impose limits for existing industries (phased in) Such measures may impact industry investment in community.
Guiding Principles JAMES Plant meets Regulations Provincial and Federal regulations Redundancy (Reliability) Provincial Federal Wastewater Federal Wastewater Municipal Wastewater (Secondary Systems Effluent Regulations (MWR) Treatment) Regulation (WSER) Organic Matters Biosolids Recycling Regulation (Class A) (OMRR) 17
Assumptions Abbotsford Mission Residential Residential Climate Change & ICI Growth and ICI @1.6% Growth @ 2% annually Extra Phosphorus Sumas, WA Strength effluent limit growth at 2.8% (High load) not (per agreement) Industries applicable 18
