Fla. Admin. Code R. 64E-8.002
No person shall construct a new water well to supply a Limited Use Public Water System unless a well construction permit has been issued by the appropriate water management district or their delegated well permitting agents, in accordance with Rule 62-532.400, F.A.C., and Chapter 40A-3, 40B-3, 40C-3, 40D-3, or 40E-3, F.A.C. All wells serving Limited Use Public Water Systems must be constructed in accordance with Rule 62-532.500, F.A.C., and Chapter 40A-3, 40B-3, 40C-3, 40D-3, or 40E-3, F.A.C.
(1) To apply for new construction or modification of a Limited Use Public Water System, an applicant must complete Form DH 4092B, Application for Limited Use and Multifamily Water System Construction Permit. Form DH 4092B, effective 9/07, is hereby adopted and incorporated by reference, and can be obtained from the Department of Health, Division of Environmental Health/Water Programs at: 4052 Bald Cypress Way, Bin C22, Tallahassee, Florida 32399-1742, at HYPERLINK "http://www.doh.state.fl.us/" www.doh.state.fl.us/environment/water/manual/encl1.htm, or from the County Health Department (CHD). The applicant must submit a completed Form DH 4092B to the Department along with:
(2) Distances between contaminant sources and potable water supply wells shall be maintained as specified in subsection 62-532.400(7), F.A.C., Water Well Permitting and Construction Requirements.
(3) Water systems shall be equipped with:
(4) Systems shall be sized and designed as follows, unless designed by a professional engineer:
| PD = (GPD/T) x 0.1 + IF, where: |
| PD is Peak Demand in Gallons per minute (GPM) |
| GPD is projected Gallons per day from Rule 64E-6.008, F.A.C., Table I |
| T is daily time of system operation in hours (Use sixteen (16) for limited use community systems or facilities open ten (10) or more hours per day; use eight (8) for all other facilities) |
| IF is the Irrigation flow factor (Use five (5) if site has lawn or landscaping; use zero (0) if site has none). |
(b) Minimum storage tank size:
1. A hydropneumatic tank shall be at least ten (10) times the PD. For a flexible diaphragm or bladder tank, the amount of water delivered between pump shutdown and start shall equal or exceed the PD. Therefore:
| Gross Storage Tank Volume | no disinfection = PD × 10 |
|---|---|
| Drawdown Volume | bladder tank = PD |
2. Beginning on the effective date of this rule, where continuous disinfection is required for groundwater supplied systems to remove confirmed microbiological contamination, Table 1 shall be used to determine the minimum water contact time and free chlorine residual concentration needed at various water temperatures:
| Contact Time | Water Temperature1 |
|---|
Table 1 Notes:
Above values are based on a water pH of no greater than 9.0 and a baffling factor of 0.1 (no baffling). Water temperature, pH and free chlorine residuals are based on the water exiting the contact tank.
1 For initial design of disinfection systems, use the coldest anticipated water temperature exiting the contact tank.
a. Therefore, the effective water contact volume for groundwater supplied systems shall be a minimum of fifteen (15), thirty (30) or forty-five (45) times the PD (to achieve a minimum water contact time of 15, 30 or 45 minutes with the disinfectant at peak demand flow, based on Table 1 values).
b. The effective water contact volume in hydropneumatic tanks shall be no more than 50% of the gross hydropneumatic tank volume, therefore:
Gross Hydropneumatic Tank Volume = PD x Contact Time/0.5
c. A flexible diaphragm or bladder storage tank may not be used as a contact tank.
d. 100% of the volume of a second, airless retention tank may be considered effective volume.
e. Influent and effluent contact tank piping shall enter and exit at opposite ends of the longest tank dimension.
(5) Piping:
| Table 2: Minimum Water System Pipe Size |
| For GPM1 up to: | Or length2 up to: | Use pipe diameter: |
|---|---|---|
| 6 | 50' | 1/2'' |
| 10 | 100' | 3/4'' |
| 15 | 200' | 1'' |
| 25 | 300' | 1 1/4'' |
| 35 | 400' | 1 1/2'' |
| 60 | 600' | 2'' |
| 90 | 800' | 2 1/2'' |
| 125 | 1,000' | 3'' |
Table 2 Notes:
These figures prevent water velocity from exceeding six (6) feet per second, and pressure loss from exceeding twenty (20) pounds per square inch per one-hundred (100) feet of pipe at peak demand based upon Hazen & Williams friction loss tables using constant = 150.
1 Use Gallons per minute flow from Peak Demand calculation in subsection (4) above.
2 Distribution pipe lengths shall be summed to find the length factor in column two.
(7) The Department shall issue a permit to construct or modify a Limited Use Public Water System provided that:
(9) Upon completion of water system construction or modification, the applicant shall perform a water quality clearance as follows:
(a) Microbiological analysis of five (5) source water samples:
1. One (1) source water sample shall be collected per day for five (5) days within a period of twenty-three (23) consecutive days. Collection of two (2) samples per day is permitted if collected six (6) hours apart and the pump is run at rated capacity for at least fifteen (15) minutes before each collection.
2. No more than one (1) of these five (5) samples and neither of the last two of these samples shall reveal the presence of coliform bacteria.
(e) Any analyses required per subsection 64E-8.006(4), or Rule 64E-8.007, F.A.C.
The results of such analyses shall not exceed the Maximum Contaminant Levels (MCL) or Health Advisory Levels (HAL) listed in subsection 64E-8.006(2), F.A.C.
(10) To obtain approval to place a new or modified Limited Use Public Water System into service, the applicant must submit a completed Form DH 4092A, Application for Limited Use Public Water System Operation, and obtain either an annual operating permit, or a Registration exemption as described in subsection 64E-8.004(5), F.A.C. Form DH 4092A, effective 9/07, is hereby adopted and incorporated by reference, and can be obtained from the Department of Health, Division of Environmental Health/Water Programs at: 4052 Bald Cypress Way, Bin #C22, Tallahassee, Florida 32399-1742, at www.doh.state.fl.us/environment/water/manual/encl1.htm, or from the CHD.
(a) The Department shall then issue an annual operating permit or a Registration provided that:
1. The Department has inspected the system and has verified that it was constructed according to the approved plans, in compliance with this section, and meets the operating and maintenance standards of Rule 64E-8.005, F.A.C.
2. Satisfactory results of the analyses listed in subsection (9), above, have been submitted.
3. A copy of the well completion report prepared per Rule 62-532.410, F.A.C., has been submitted.
