40D-21.651. Phase IV: Critical Water Shortage

(1) A Phase IV Water Shortage is a hydrologic or climatic condition where multiple regional Drought Indicators have extremely abnormal values, or the local Drought Indicator for a specific public supply has a critically abnormal value, such that conditions warrant the temporary suspension of nonessential use and/or initiation of supply augmentation. The following measures shall be in effect during a Phase IV declaration unless otherwise provided in the order implementing a Phase IV Water Shortage.

(2) Indoor Use. Indoor Uses should be voluntarily reduced.

(3) Essential Uses.

(b) Water Utility Use. Water Utility Uses shall be subject to paragraph 40D-21.641(3)(b), F.A.C., with the following modifications:

1. If specifically Ordered by District, increase the frequency of system status reports or transmittal of demand data.

2. Immediately notify the District’s applicable Demand Management staff about any new water supply emergency and any supply supplementation or replacement that occurs in order to address or prevent such an emergency.

3. Identify, based on the water utility’s customer demographics and system characteristics, and implement additional means by which the water utility will temporarily maintain or reduce system demand during the Water Shortage declaration. This requirement shall include listing and qualifying the implementation of these additional means on each system status report.

Place temporary limits on potable water service in response to a location-specific request from the District to remedy a violation of this chapter that the District has determined is causing, or is likely to cause, a public health hazard or property damage. These limits do not necessarily involve suspension of service; however, at a minimum, such limits shall involve constraining the user to the amount of water necessary for reasonable Indoor Uses. One example of such a limitation is the assessment of a surcharge for any amount of water utilized beyond that necessary for reasonable Indoor Uses. The applicable public supply water utility shall determine the limitation method and consider any mitigating circumstances when determining what constitutes reasonable Indoor Uses for a specific customer, such as the number of persons in the household or medical needs.
