NOTES:

  1. ALL FLOWS SHOWN ARE PEAK, IN LITRES PER SECOND (L/s).
  2. CURRENT FLOW ALLOCATIONS ARE BASED ON 1973 PRIESTMAN REPORT AND 1994 WESTERN COMMUNITIES TRUNK SEWER COST SHARING REPORT.
  3. 2045 FLOW ALLOCATIONS ARE BASED ON REGIONAL GROWTH STRATEGY AND 2004 INFLOW & INFILTRATION RATES. THESE ALLOCATIONS WILL BE AVAILABLE WHEN ALL LIQUID WASTE MANAGEMENT PLAN (LWMP - CHAPTER 16) UPGRADES ARE COMPLETED.
  4. TOTAL PEAK FLOWS MAY NOT ADD CUMULATIVELY DUE TO POPULATION-BASED HARMON PEAKING FACTOR.
  5. LOCATION AND EXTENT OF CRD SEWERS AND FACILITIES AS DEPICTED ARE PRELIMINARY AND MAY CHANGE IN ACCORDANCE WITH THE FINAL SYSTEM DESIGN. PROPOSED UPGRADES AS SHOWN ARE REQUIRED TO MEET 2045 FLOW ALLOCATIONS.
  6. SAANICH'S ALLOCATED FLOW AT MACAULAY REMAINS AT 1128 L/s AS EXCESS IS STORED IN MARIGOLD TANK.
