Assessed generic options to show how investments have benefits, and dis-benefits, beyond their core purpose
There are four primary aspects of water planning (water resources, wastewater, environment and flooding) that are currently appraised in a largely siloed manner using different approaches, across different spatial scales.
Through Phase 1 we looked to develop a consistent approach to planning, so that it would be possible for options with benefits to more than one system to be included for appraisal in more than one planning framework. We identified a common set of metrics and planning assumptions, to demonstrate the potential to select options that work together for increased benefits across the planning frameworks.
For planning to become more integrated it is necessary to agree:
- A common set of metrics.
- A common set of planning assumptions.
- A consistent set of management targets and performance thresholds.
- A common set of scenarios.
- A consistent categorisation of option types.
Phase 1 of this IWMF Programme undertook a high-level review of the benefits of different option types and trialled a modelling exercise to assess how benefits could be scored.
