Current through Reg. 50, No. 138; July 16, 2024
(1) System
				  storage shall not be required where another permitted reuse system or effluent
				  disposal system is incorporated into the system design to ensure continuous
				  facility operation in accordance with the requirements of Chapter 62-600,
				  F.A.C. If system storage is not required, provision of flow equalization or
				  storage should be evaluated in the engineering report to ensure that reclaimed
				  water flows will match the demand pattern during a diurnal cycle.
(2) Unless exempted by subsection
				   62-610.464(1),
				  F.A.C., system storage ponds shall have capacities determined as follows.
				  Requirements for system storage pond capacity shall be as contained in Rule
				   62-610.414, F.A.C., for
				  restricted access slow-rate land application systems. System storage or a
				  limited wet weather discharge authorization shall be required for wet weather
				  conditions. At a minimum, system storage capacity shall be the volume equal to
				  three times that portion of the average daily flow of the total reuse capacity
				  for which no alternative reuse or disposal system is permitted.
(3) In addition, a separate, off-line system
				  for storage of reject water shall be provided, unless another permitted reuse
				  system or effluent disposal system is capable of discharging the reject water
				  in accordance with requirements of Chapter 62-600, F.A.C. Reject water storage
				  shall have sufficient capacity to ensure the retention of reclaimed water of
				  unacceptable quality. At a minimum, this capacity shall be the volume equal to
				  one day flow at the average daily design flow of the treatment plant or the
				  average daily permitted flow of the reuse system, whichever is less. Provisions
				  for recirculating this reject water to other parts of the treatment plant for
				  further treatment shall be incorporated into the design.
(4) Requirements for system storage and
				  reject water holding ponds shall be as contained in Rule
				   62-610.414, F.A.C., except for
				  the following:
(a) System storage ponds do
				  not have to be lined.
(b) Reject
				  storage ponds shall be lined or sealed to prevent measurable seepage.
(c) Existing or proposed lakes or ponds (such
				  as golf course ponds) are appropriate for storage of reclaimed water and
				  stormwater management if all Department rules are met and the use of lakes or
				  ponds for reclaimed water storage will not impair the ability of the lakes or
				  ponds to function as a stormwater management system. Rule
				   62-610.830, F.A.C., contains
				  permitting requirements for these types of storage lakes or ponds. Lakes or
				  ponds (such as golf course ponds) used to store reclaimed water are not
				  required to meet the storage pond design, construction, and operation
				  requirements in subsections
				   62-610.414(7) and
				  (8), F.A.C.
