https: z/khoth u Vi e n .comAppendix D: Deriving our investment planTRENTWATERD1 Unconstrained supply / demand optionsAn important stage in the water Appendix-D-Deriving-our-investment-plan resources planning process is the identification and evaluation of the range of options we have available to US for managing the supply / demand balance over time. The Environment Agency's Water Resources Planning Guideline (WRPG) includes the following summary of the recommended steps we should ta Appendix-D-Deriving-our-investment-planke in deriving the preferred investment options.Figure D1.1: The stages of an option appraisal process1 Severn Trent Water: Final Water Resources ManaAppendix-D-Deriving-our-investment-plan

We used a screeningAppendix-D-Deriving-our-investment-plan

This strategic process is not a substitute for the detailed, option appraisal that would be needed to support site specific planning or abstraction consents.The stages of this process have taken an initial list of 132 potential o Appendix-D-Deriving-our-investment-planptions to enhance water supply capability, and have reduced this to a set of 30 feasible options (plus sub-options) from which we have derived our invAppendix-D-Deriving-our-investment-plan
