Local Water Supply Plan Template July 8, 2016 Strategy to reduce residential per capita demand Timeframe for completing work ❑ Offer free or reduced cost water use audits)for residential customers. ❑ Implement a notification system to inform customers when water availability conditions change. ❑ Provide rebates or incentives for installing water efficient appliances and/or fixtures indoors(e.g., low flow toilets, high efficiency dish washers and washing machines,showerhead and faucet aerators,water softeners,etc.) ❑ Provide rebates or incentives to reduce outdoor water use (e.g.,turf replacement/reduction, rain gardens, rain barrels, smart irrigation,outdoor water use meters,etc.) ❑ Identify supplemental Water Resources ❑ Conduct audience-appropriate water conservation education and outreach. ❑ Describe other plans Objective 3:Achieve at least a 1.5% per year water reduction for Institutional, Industrial, Commercial, and Agricultural GPCD over the next 10 years or a 15% reduction in ten years. Complete Table 26 by checking which strategies you will used to continue reducing non- residential customer use demand and project a likely timeframe for completing each checked strategy (add rows for additional strategies). Where possible, substitute recycled water used in one process for reuse in another. (For example, spent rinse water can often be reused in a cooling tower.) Keep in mind the true cost of water is the amount on the water bill PLUS the expenses to heat, cool, treat, pump, and dispose of/discharge the water. Don't just calculate the initial investment. Many conservation retrofits that appear to be prohibitively expensive are actually very cost-effective when amortized over the life of the equipment. Often reducing water use also saves electrical and other utility costs. Note: as of 2015, water reuse, and is not allowed by the state plumbing code, M.R. 4715 (a variance is needed). However several state agencies are addressing this issue. Table 26.Strategies and timeframe to reduce institutional,commercial industrial,and agricultural and non-revenue use demand Strategy to reduce total business, industry,agricultural demand Timeframe for completing work ❑ Conduct a facility water use audit for both indoor and outdoor use, including system components ❑ Install enhanced meters capable of automated readings to detect spikes in consumption ❑ Compare facility water use to related industry benchmarks, if available(e.g., meat processing,dairy,fruit and vegetable, beverage,textiles, paper/pulp, metals,technology, petroleum refining etc.) ❑ Install water conservation fixtures and appliances or change processes to conserve water ❑ Repair leaking system components(e.g., pipes,valves) 41
