Local Water Supply Plan—Centerville <br /> A. Triggers for Allocation and Demand Reduction Actions <br /> Complete table 22 by checking each trigger below, as appropriate, and the actions to be taken at various <br /> levels or stages of severity. Add in additional rows to the table as needed. <br /> Table 22.Short and long-term demand reduction conditions,triggers and actions <br /> Protect Surface Water Flows ❑ Low stream flow conditions Q Increase promotion of conservation <br /> 0 DNR Reports of declining measures <br /> lake levels ❑ Other: <br /> Short-term demand reduction 0 Extremely high seasonal Q Enforce the critical water deficiency <br /> (less than 1 year) water demand (more than ordinance to restrict or prohibit lawn <br /> double winter demand) watering,vehicle washing,golf course <br /> 0 Loss of treatment capacity and park irrigation &other nonessential <br /> 0 Lack of water in storage uses. <br /> 0 State drought plan Q Supply augmentation through emergency <br /> 0 Well interference interconnections. <br /> ❑ Other: ❑Water allocation through <br /> ❑ Meet with large water users to discuss <br /> user's contingency plan. <br /> Long-term demand reduction 0 Per capita demand Q Develop a critical water deficiency <br /> (>1 year) increasing ordinance that is or can be quickly <br /> ❑Total demand increase adopted to penalize lawn watering, <br /> (higher population or more vehicle washing,golf course and park <br /> industry) irrigation &other nonessential uses. <br /> ❑Water level in well(s) below Q Meet with large water users to discuss <br /> elevation of user's contingency plan. <br /> ❑ Other: Q Enhanced monitoring and reporting: <br /> audits,meters, billing,etc. <br /> Governor's"Critical Water 0 Determined by State 0 Enact a water waste ordinance that <br /> Deficiency Order"declared targets overwatering(causing water to <br /> flow off the landscape into streets, <br /> parking lots,or similar),watering <br /> impervious surfaces(streets,driveways <br /> or other hardscape areas),and negligence <br /> of known leaks, breaks,or malfunctions. <br /> B. Conservation Objectives and Strategies -Key benchmark for DNR <br /> This section establishes water conservation objectives and strategies for eight major areas of water use. <br /> Objective 1: Reduce Unaccounted (Non-Revenue) Water loss to Less than 10% <br /> The Minnesota Rural Waters Association,the Metropolitan Council and the Department of Natural <br /> Resources recommend that all water uses be metered. Metering can help identify high use locations <br /> and times, along with leaks within buildings that have multiple meters. <br /> It is difficult to quantify specific unmetered water use such as that associated with firefighting and <br /> system flushing or system leaks. Typically, water suppliers subtract metered water use from total water <br /> pumped to calculate unaccounted or non-revenue water loss. <br /> Is your ten-year average (2005-2014) unaccounted Water Use in Table 2 higher than 10%? Q Yes ❑ No <br /> 23 <br /> 68 <br />
