Evaluation Criteria

  • Energy Efficiency - the use of improved technologies and practices to deliver equal or better services with less [net] energy... or with a smaller "carbon footprint" from energy consumption.  Infrastructure not devoted specifically to this purpose must generate an energy savings of 20% or greater to be considered energy efficient.
  • Water Efficiency - the use of improved technologies and practices to deliver equal or better services with less water.
  • Green Infrastructure - practices that manage wet weather to maintain and restore natural hydrology by infiltrating, evapo-transpiring and capturing and using stormwater.  These must be implemented in direct relation to drinking water utility facilities.
  • Environmental Innovation - demonstrates new and/or innovative approaches to delivering service and/or managing water resources in a more sustainable way.  This includes projects that achieve public health protection and environmental protection objectives at the least life-cycle costs.

Business Cases (i.e. Making the Case that a Project is "Green")

Business cases are required for projects that are not "categorically green" in order to justify their "green" qualifications through their adherence to the above evaluation criteria.  Some typical examples of "categorically green" projects include the following:

  • Clean Energy Generation - where energy is either generated from or for the drinking water system that does not generate carbon emissions.  Examples include:
    • Turbines / hydrogenerators installed in pipeline.
    • Solar panels or wind turbines used to (supplement) power (to the) water treatment facilities.
  • Variable Frequency Drive (VFD) Installation with the following conditions:
    • There must be adequate training for the utility's staff which operates this equipment (consistent with current operator certification requirements).
    • Current limiting and auto restart features must be integrated into VFDs while ensuring that the controls are intuitive.
  • Energy Audits that are reasonably expected to result in a capital project.
  • Water Meter
    • Installation in a previously unmetered location.
    • Installation where existing meters are broken/malfunctioning.
    • Retrofit adding Automatic Meter Reading (AMR) or leak detection capabilities to an existing meter.
  • Leak Detection Equipment Purchase.
  • Water Audits that are reasonably expected to result in a capital project.
  • Green Roofs.

Some typical examples of projects that are not "categorically green" and their required business cases include the following:
