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

System Condition
Optimize infrastructural renewal and growth related projects Average age of pipe is 30 Years. Useful Life is 75 Years
SLIDE 25
Issues and Opportunities
Dry vs Wet industry (e.g. food processing)
Warehouse (50 eq. ppl) Food processor (2,000 eq. ppl) Wet industry – 15% of total Abbotsford flows
Infrastructure Upgrades
Maximize sewer capacity & mitigate risks (350 to185 L/cap/d) Sewer Odour Corrosion

Assumptions
Keep current Sewer Service Area the same Lands outside Sewer Service Area to remain
- n private onsite
treatment* Residential growth will follow OCP projections Industrial, Commercial and Institutional (ICI) sector also grows with residential sector
* Unless approached by Province due to public health reasons
