  1. Liquid Waste Management Plan Has Many Issues by David Langley & Bob Furber

  2. Major Issues • LWMP design is based on 2000 to 2003 data • Much has changed as a result of the CRD's 3R and water conservation initiatives • If current plans proceed, there will be substantial sewage treatment OVERCAPACITY • And $200 Million plus over expenditure • Avoidable social and ecological damage • Many design assumptions and estimates do not fit current measurements

  3. Total Water Processed Through Water Treatment Plants 10 Year Trend – January (no yard irrigation) The CRD's Water Conservation Plan has been very successful

  4. Dramatic changes in recent measured Regional sewage flows

  5. Measured & Projected Flows Diverge - Dramatically Measured vs Projected Design) Sewage Flows for Region

  6. Opportunity: Remove Satellite Plants: Save over $200 Million in Capital; Over $3 Million/a

  7. CRD ADWF SEWAGE FLOWS Water Conservation Largely Attained in 2015 The Macloughlin Plant now has Excess Capacity

  8. Measured and Projected Biological Loads Diverge - Dramatically Projected (Design) vs. Measured BOD Loading

  9. Can we Reduce our Biological Load?

  10. Garburators are definitely not green

  11. Can McLoughlin Plant Capacity be Increased? Replace Water Reclamation by BAFs – 30% Incr.

  12. Conclusion • A central plant (McLoughlin) can handle sewage for the entire region. • The $150 Million Saanich East plant is not required. • The West Shore plant can be delayed for decades or avoided altogether. • Only the Western Communities will have the opportunity to promote green developments (i.e, West Hills). • Remaining municipalities will be tied to Limited technology for a generation or more. • Limited: Handle today's perceived problem: BOD & TSS. Not tomorrow's COC. No resource recovery.

  13. The LWMP Dilemma • Proceed quickly before Provincial and Federal dollars dry up. • Get as much as you can with $0.30 dollars. • Spending leads to increase in Union jobs. • We have already gone too far to turn back. vs. • Stop the train. It is heading for disaster. • Overspending will lead to cutbacks and loss of jobs. • Start the trip anew: Plan it carefully and thoughtfully. • Provincial and Federal dollars not yet committed.
