Conceptual Alternatives for Clover Point Wet Weather Facility (035-DP-2)

Discussion Paper Summary

A wet weather wastewater facility at Clover Point will take considerable planning to design and build. This discussion paper looks at the design parameters for the facility, the conceptual level plans of three technology approaches and evaluates the operational impacts, risk and comparative costs of the three options.

Design Parameters

Wet weather flow depends highly on the amount of inflow and infiltration, of which Clover Point has a great deal. The CRD has begun a wet weather and dry weather sampling program to characterize the wastewater quality. This will help to determine the best facility scenario.

The sampling program includes

  • Wet weather flows
  • Event frequency and duration
  • Summary of the design parameters

Conceptual Plans

There are three conceptual plans for the Clover Point facility, which are covered in Discussion Paper 035-1.

Choosing the Right Alternative

Four main risks have been identified that may help to give insight into the desirability of each plan alternative.

  • Public acceptance
  • Technical and financial risk
  • Changes in regulatory requirements
  • Climate change (resulting in a possible rise in sea levels)
