CITY SEWER MASTER PLAN
Purpose Develop long- Identify term capital impact due to program 200K (costs, timing population and upgrade growth priority) Identify impact due to commercial, industrial and institutional growth
Background Stage 4 Stage 2 Stage 3 Stage 1 BACKGROUND REVIEW ANALYSIS AND EVALUATION AND DATA ASSESSMENT • Reviewed GIS Data • Reviewed current and future population • Reviewed infiltration & inflow rates • Reviewed sewer loads & flow patterns • Built sewer model June 2018 April 2017 Spring 2018 Fall/Winter 2017
System Overview Services 132,000 people in Abbotsford, including Matsqui • & Sumas FN Services City of Sumas, WA (~1000 people) • Sewer flows north to the JAMES plant • 80% of pipes are CCTV inspected • – 94% in good condition; – 4% approaching critical condition; and – 2% in critical condition 34 33
City Sewer Collection System
System Condition Average age of pipe is 30 Years. Useful Life is 75 Years Optimize infrastructural renewal and growth related projects
Issues and Opportunities Dry vs Wet industry Maximize (e.g. food sewer processing) Upgrades capacity & Corrosion or Climate Warehouse mitigate Sewer of pipes relocation change & Infrastructure Resiliency (50 eq. ppl) risks Upgrades Odour and of sewers Sewer manholes in Right of overflows Food (350 processor Ways to185 (2,000 eq. L/cap/d) ppl) Wet industry – 15% of total Abbotsford flows
Guiding Principles Sewer Regulations Bylaw* Municipal & Wastewater Regulations Development Bylaw* * Design criteria in bylaws will be reviewed in the master plan
Assumptions Lands outside Sewer Service Keep current Area to remain Sewer Service Area the same on private onsite treatment* * Unless approached by Province due to public Industrial, health reasons Commercial and Residential Institutional (ICI) growth will sector also follow OCP grows with projections residential sector
Next Steps Stage 4 Stage 2 Stage 3 Stage 1 BACKGROUND REVIEW ANALYSIS AND EVALUATION AND DATA ASSESSMENT • Run sewer model • Optimize sewer system • Identify infrastructure upgrades and their timing • Prioritize upgrades • Integrate Neighborhood Servicing Plans into masterplan (U District, City Centre, Downtown) Spring 2018 Fall/Winter 2017 April 2017 June 2018
CITY WATER MASTER PLAN
Purpose Identify Impact on Water infrastructure for Identify impact commercial due to 200K industrial, population institutional and growth agricultural growth Long-term capital program with costs, timing and upgrade priority
Background Stage 4 Stage 2 Stage 3 Stage 1 BACKGROUND REVIEW ANALYSIS AND EVALUATION AND DATA ASSESSMENT • Reviewed GIS Data • Reviewed AMI Data • Reviewed current and Future Population • Aligned with Water Source Supply Study and Joint Water Masterplan • Updated Water Model Fall/Winter 2017 Spring 2018 April 2017 June 2018
