Chapter 40E-21 - WATER SHORTAGE PLAN
Part V - SPECIFIC RESTRICTIONS
Section 40E-21.541 - Phase III Extreme Water Shortage

1. The use of water for firefighting, safety, sanitation, health and medical purposes and other essential uses shall not be restricted.

2. Fire hydrant flushing shall be undertaken only on an emergency basis.

3. Sanitary sewer line flushing and testing shall not be restricted except on a voluntary basis.

1. Residential type domestic use shall be voluntarily reduced to 40 gallons per person per day.

2. Domestic type use in industrial and commercial establishments shall be voluntarily reduced.

1. Initial pressure at the point of use (meter) shall be reduced to levels no greater than 45 pounds per square inch. Voluntary initial pressure reductions below 45 psi shall be made consistent with the utility's ability to maintain adequate service and fire flow pressures. Upon reduction of pressure, the utility shall notify the appropriate fire-fighting agencies and make arrangements for direct communication when additional pressure is required.

2. New water line flushing and disinfection shall be restricted to the hours of 7:00 p.m. to 7:00 a.m. seven days per week.

3. As may be appropriate the utility shall institute additional voluntary conservation measures such as reclaiming of backwash water, improving and accelerating leak detection surveys and repair programs, installing and calibrating meters, and stabilizing and equalizing system pressures.

1. Commercial car washes shall be restricted as follows:

2. Water used for commercial and industrial processes shall be voluntarily reduced.

3. Water use for cleaning, adjusting and repair of irrigation systems by a licensed person or entity shall be restricted as follows:

4. Water use for pesticide application under the supervision of a licensed pest control operator shall be voluntarily reduced. Under the provisions of this subparagraph, the applicator must be on the premises when water is applied outside of the hours allowed for irrigation.

5. Water use for well development under the supervision of a licensed well contractor shall be voluntarily reduced.

6. Water use for mobile equipment washing by a licensed person or entity shall be voluntarily reduced.

1. Overhead irrigation shall be restricted to the hours of 7:00 p.m. to 7:00 a.m.

2. Low volume irrigation hours shall not be restricted.

3. All irrigation systems shall be operated in a manner that will maximize the percentage of water withdrawn and held which is placed in the root zone of the crop and will minimize the amount of water which is withdrawn and released or lost to the user but is not immediately available for other users.

4. Users having access to more than one source class shall maximize the use of the lesser or least restricted source class.

5. The District's allocation determination for agricultural irrigation within the entire Lake Okeechobee Region as depicted on Figure 21-4 will be based on 45% cutbacks to the calculated 1 in 10 supplemental crop demands calculated on a weekly basis. The entire Lake Okeechobee Region supplemental crop demands will be distributed among the sub-basins depicted in Figure 21-4 based on a grouping of crop types, irrigation methods (e.g. flood irrigated crops versus micro irrigated crops), the associated acreage totals as identified in the individual water use permits combined with the associated 1 in 10 evapotranspiration demands of the crops. An additional amount of water from Lake Okeechobee will be added to the weekly allocation as necessary to account for conveyance losses that occur through seepage and free surface evaporation from the Central and Southern Florida Flood Control System Project canals. The share of the entire Lake Okeechobee Region irrigation allocation available to each sub-basin may be further adjusted to prioritize water deliveries among crops, as long as the sum of the sub-basin allocations does not exceed the weekly allocation for the entire Lake Okeechobee Region and that equity among users and sub-basins is assured. Such adjustments shall be based upon irrigation efficiency, potential for economic loss, and acreage irrigated as opposed to non-irrigated acreage. Withdrawals by each user within the Lake Okeechobee Region as described in subsection 40E-21.691(3), F.A.C., shall be limited to an amount that represents each user's share of their sub-basin weekly allocation based on their permitted crop type and irrigated acreage. The District shall provide the users with the data necessary to calculate their weekly allotment of water.

6. Overhead irrigation for field grown citrus nursery stock moisture stress reduction shall be allowed daily for 10 minutes per irrigation zone from 11:30 a.m. to 12:00 Noon, 1:30 p.m. to 2:00 p.m. and 3:30 p.m. to 4:00 p.m.

1. Soil flooding for vegetable seed planting, rice planting, burning of sugarcane prior to harvest and to permit harvesting of sod shall be voluntarily reduced.

2. Soil flooding for all other purposes shall be prohibited.

1. Low volume irrigation uses and low volume hand watering shall be voluntarily reduced.

2. Overhead irrigation uses shall be restricted as follows:

3. Flood irrigation systems shall be restricted to 4 days per month.

1. For installations which have been in place for less than 30 days, and

2. Low volume irrigation and low volume hand watering of new landscaping shall be voluntarily reduced.

3. Cleaning and adjusting of new irrigation systems shall be restricted to 10 minutes per zone on a one time basis.

1. For existing installations less than 5 irrigated acres in size, water use for irrigation shall be restricted to the hours from 4:00 a.m. to 7:00 a.m. for all types of irrigation, except low volume irrigation, and 5:00 p.m. to 7:00 p.m. for low volume hand watering only, one day per week.

2. For existing installations 5 irrigated acres or greater in size, water use for irrigation shall be restricted to the hours from 12:01 a.m. to 7:00 a.m., one day per week.

3. Water use for cleaning, adjusting and repair of existing irrigation systems shall be limited to ten minutes per zone per week.

4. Low volume irrigation uses shall be voluntarily reduced.

2. Watering of pervious non-vegetated recreational/sporting surfaces shall be restricted to ten minutes of application prior to each recreational/sporting event. Low volume watering shall be used.

1. Irrigation of greens shall be voluntarily reduced and shall be accomplished during non-daylight hours.

2. Irrigation of tees shall be restricted to non-daylight hours three days per week. The front nine holes shall be restricted to Monday, Wednesday and Saturday and the back nine holes shall be restricted to Tuesday, Thursday and Sunday.
