10 projections in Part 4. Metropolitan Council will provide technical guidance and tools such as the Conservation Toolbox to assist in the development of this portion of the local water supply plan. However, the DNR and the community are the primary partners responsible for developing the details of the conservation plan. Proposed approaches to meet extended water demand projections Building on the information provided in Part 2 of the local water supply plan template, Part 4 of the local water supply plan template should describe: • The adequacy of the existing water supply system to meet demand through 2040. • Proposed approaches to meet water demand through 2040, if the current system is inadequate to do so, that consider the potential issues identified for the community within Appendix 1 of the Master Water Supply Plan and by local monitoring and evaluation. Proposed approaches may include: • Continuing to use existing groundwater or surface water sources, supported by monitoring and evaluation to provide warning of developing problems and a plan for back-up should limitations occur. • Using new (currently not in use) approaches with a lower likelihood of causing well interference, aquifer or surface water impacts, or added treatment costs due to contamination. Potential approaches include expanded conservation, interconnections with neighbors, groundwater, surface water, reclaimed stormwater, and reclaimed wastewater. In some cases, a multi -community approach may be warranted. The DNR and Metropolitan Council will provide planning assistance and technical information to support development of multi- community water supply management plans, where appropriate. Metropolitan Council will also help support the work outlined in the local water supply plan template through public outreach to increase knowledge by the general public about water supply issues, partnering on technical studies, promoting and supporting water conservation, investigating reuse of treated wastewater, and supporting investments in water supply. Results from these efforts will be incorporated into regional analyses and in future updates to the Master Water Supply Plan. More detailed guidance on how local plans can incorporate water supply considerations is provided in the Metropolitan Council's Local Planning Handbook. Review process Metropolitan Council and DNR cooperate in the process to review local water supply plans. Figure 3 shows the decision process review of water supply plans, including the benefits of completing and approving a local water supply plan. WATER SUPPLY MASTER PLAN- Draft June 2015
