Local Water Supply Plan Template —December 8, 2015 Table 22. Short and Tong -term demand reduction conditions, triggers and actions Objective Triggers Actions Protect Surface Water Flows ❑ Low stream flow conditions 0 Reports of declining wetland and lake levels 0 Other: declining surface water quality 0 Increase promotion of conservation measures 0 Other: Consider water reuse/stormwater irrigation project for golf courses, car washing facility, etc.. Short-term demand reduction (less than 1 year 0 Extremely high seasonal water demand (more than double winter demand) ❑ Loss of treatment capacity ❑ Lack of water in storage 0 State drought plan ❑ Well interference ❑ Other: 0 Enforce the critical water deficiency ordinance to restrict or prohibit lawn watering, vehicle washing, golf course and park irrigation & other nonessential uses. ❑ Supply augmentation through ❑ Water allocation through ❑ Meet with large water users to discuss user's contingency plan. Long-term demand reduction (>1 year) 0 Per capita demand increase by 20% over 5 year average ❑ Total demand increase (higher population or more industry)Water level in well(s) below elevation of 0 Develop a critical water deficiency ordinance that is or can be quickly adopted to penalize lawn watering, vehicle washing, golf course and park irrigation & other nonessential uses. 0 Enact a water waste ordinance that targets overwatering (causing water to flow off the landscape into streets, parking lots, or similar), watering impervious surfaces (streets, driveways or other hardscape areas), and negligence of known leaks, breaks, or malfunctions. ❑ Meet with large water users to discuss user's contingency plan. ❑ Enhanced monitoring and reporting: audits, meters, billing, etc. ❑ Other: Governor's "Critical Water Deficiency Order" declared Executive Order by Governor and as provided in above triggers. All of the above triggers Providing water as per water use priorities set by the City B. Conservation Objectives and Strategies - Key benchmark for DNR This section establishes water conservation objectives and strategies for eight major areas of water use. Objective 1: Reduce Unaccounted (Non -Revenue) Water loss to Less than 10% The Minnesota Rural Waters Association, the Metropolitan Council and the Department of Natural Resources recommend that all water uses be metered. Metering can help identify high use locations and times, along with leaks within buildings that have multiple meters. It is difficult to quantify specific unmetered water use such as that associated with firefighting and system flushing or system leaks. Typically, water suppliers subtract metered water use from total water pumped to calculate unaccounted or non -revenue water loss. 31
