Current through Reg. 50, No. 138; July 16, 2024
(1) Rule
				   62-610.472, F.A.C., applies to
				  projects for which complete permit applications involving the use of
				  supplemental water supplies were received by the Department on or after August
				  8, 1999. Rule  62-610.472, F.A.C., shall also
				  apply to any existing reuse system which proposes to add a new supplemental
				  water supply or to expand the facilities, structures, or pumps used for an
				  existing supplemental water supply; however, these rule requirements shall only
				  apply to the expanded or modified portion of the project. Incorporation of a
				  supplemental water supply into the reuse system shall require a permit
				  modification.
(2) Other water
				  supplies may be used by the permittee to supplement the supply of reclaimed
				  water. Surface waters, ground waters, treated stormwater, and drinking water
				  may be used to supplement the reclaimed water supply.
(3) Surface water and stormwater supplies.
(a) Surface water supplies may be used to
				  supplement the reclaimed water supply, if all of the following conditions are
				  met:
1. Disinfection is provided and the fecal
				  coliform and TSS limits established for high-level disinfection in subsection
				   62-600.440(5),
				  F.A.C., are met for the treated surface water or stormwater supply before
				  mixing with the reclaimed water. Operating protocols and reject storage
				  facilities are not required for the supplemental water supply.
2. The applicant shall provide an affirmative
				  demonstration that the quality of the resulting mixture of reclaimed water and
				  treated surface water or stormwater will be acceptable for the permitted uses
				  of the reclaimed water within the reclaimed water distribution system. The
				  following factors shall be evaluated in assessing the acceptability of the
				  mixture of reclaimed water and supplemental water:
a. The mixture shall not harm vegetation or
				  crops grown in the reuse system.
b.
				  The mixture shall enable compliance with ground water standards at the edge of
				  the zone of discharge.
c. Public
				  health shall be protected.
3. A one-way flow device shall be provided on
				  each surface water or stormwater supply line to prevent backflow of reclaimed
				  water into the surface water or into the stormwater treatment facilities. This
				  does not have to be an approved device as listed in Rule
				   62-555.360, F.A.C. A check
				  valve, flap valve, or other device may be used.
4. Continuous monitoring for disinfectant
				  residual shall be performed on the disinfected surface water or stormwater
				  supply at a point before mixing with the reclaimed water. Fecal coliforms and
				  TSS shall be monitored at this point in accordance with the schedule
				  established in Chapter 62-600, F.A.C., for high-level disinfection facilities,
				  based on the permitted capacity of the largest domestic wastewater treatment
				  facility providing reclaimed water to the reuse system.
5. The supplemental water supply pipes and
				  appurtenances shall be color coded and marked to differentiate them from the
				  reclaimed water and potable water facilities.
