Allocated Flow Capacities to Participants

Schedule B to Bylaw 2312 as Amended by Bylaw 4304

May 2020

Legend

  • Municipal Boundary
  • CRD Growth Boundary
  • CRD Core Area Sewer Service Boundary
  • DND Areas
  • Existing Sewer Main
  • Overflow/Outfall
  • Future Sewer Main
  • Wastewater Inflow Allotment at Indicated Location (Inflow ID)
  • TP: Treatment Plant
  • RT: Residuals Treatment Facility
  • PS: Pump Station

Notes:

  1. ADWF = Average Dry Weather Flow (June 1 to August 31). PWWF = Peak Wet Weather Flow (max flow over a 24-hour period). L/s = Litres per second. MLD = Mega Litres per day.
  2. The ADWF Allocations are based the Core Area Wastewater Treatment Program where the total ADWF plant capacity of 108 MLD was allocated out to each participant based on their requested capacity.
  3. PWWF is based on 4xADWF which the maximum flow allowed at McLoughlin WWTP as approved by the Ministry of Environment. These allocations will be available when the upgrades identified on the map are completed. Capacity upgrade at the Craigflower Pump Station can be achieved by forcemain twinning. Pump upgrades are not required to meet the PWWF allocation.
  4. Total peak flows may not add cumulatively at downstream locations due to system attenuation (population based on Harmon peaking factor).
  5. Inflow allocations may not add cumulatively to participant totals due to inter-municipal cross boundary connections. Inter-municipal flows are not measured; they are estimated as shown in blue text in the tables.
  6. Location and extent of future CRD sewers and facilities as depicted are preliminary and may change in accordance with the final system design.
  7. Allocations are available up until the capacity at McLoughlin WWTP has been reached. New infrastructure and reallocation of flows will then be required. Allocations can be transferred amongst participants pursuant to the terms of the bylaw.
  8. Note some infrastructure is currently being constructed as part of the Core Area Wastewater Treatment Project but is shown as existing on this map.
