Table 8 Water Use Priorities Customer Category Allocation Priority Average Day Demand .Zemarld Reduction Demand Reduction Potential. The demand reduction potential for residential use will typically be the base demand during the winter months when water use for non - essential uses such as lawn watering do not occur. The difference between summer and winter demands typically defines the demand reduction that can be achieved by eliminating non - essential uses. In extreme emergency situations lower priority water uses must be restricted or eliminated to protect first priority domestic water requirements. Short -term demand reduction potential should be based on average day demands for customer categories within each priority class. Triggers for Allocation and Demand Reduction Actions. Triggering levels must be defined for implementing emergency responses, including supply augmentation, demand reduction, and water allocation. Examples of triggers include: water demand >100% of storage, water level in well(s) below a certain elevation, treatment capacity reduced 10% etc. Each trigger should have a quantifiable indicator and actions can have multiple stages such as mild, moderate and severe responses. Check each trigger below that is used for implementing emergency responses and for each trigger indicate the actions to be taken at various levels or stages of severity in Table 9. ® Water Demand (GPD) Potential (GPD) Residential 1 208,000 74,000 Institutional 5 ❑ Security Breach Commercial 5 3 8, 751 0 Industrial 5 Incl in commercial Irrigation 6 15,000 15,000 Wholesale 6 Non - essential 6 TOTALS 266, 000 89,000 GPD — Gallons uer Day Demand Reduction Potential.
