City of Ramsey Local Water Supply Plan 2018-2028 4.Water use for power production above the use provided for in the contingency plan. 5.All other water use involving consumption of more than 10,000 gallons per day. 6.Nonessential uses – car washes, golf courses, etc. Water used for human needs at hospitals, nursing homes and similar types of facilities should be designated as a high priority to be maintained in an emergency. Lower priority uses will need to address water used for human needs at other types of facilities such as hotels, office buildings, and manufacturing plants. The volume of water and other types of water uses at these facilities must be carefully considered. After reviewing the data, common sense should dictate local allocation priorities to protect domestic requirements over certain types of economic needs. Water use for lawn sprinkling, vehicle washing, golf courses, and recreation are legislatively considered non-essential. Table 18. Water use priorities Customer Category Allocation Priority Average DailyDemand Short-Term Emergency (GDP) Demand Reduction Potential (GPD) Residential 11,542,000 1,370,000 Institutional 214,600 10,000 Commercial3163,40015,000 Industrial 4 Irrigation 5 Wholesale N/A Non-Essential 6 TOTAL 1,720,000 1,395,000 GPD – Gallons per Day The emergency demand reduction potential for all uses will typically equal the difference between maximum use (summer demand) and base use (winter demand). In extreme emergency situations, lower priority water uses must be restricted or eliminated to protect priority domestic water requirements. Emergency demand reduction potential should be based on average day demands for customer categories within each priority class. Use the tables in Part 3on water conservation to help you determine strategies. Complete Table 19 by selecting the triggers and actions during water supply disruption conditions. 37 November 29, 2018
