Potable Reuse Commission

Develop a framework for potable reuse implementation in Florida to augment future water supply and support water quality initiatives.

Advise elected officials and regulatory agencies on statutory and regulatory challenges and present consensus based solutions.

Mission

5

• Consensus based effort by water professionals and a diverse stakeholder group to identify and address technical, regulatory, and implementation barriers to potable reuse in Florida.

• For the 2019 legislative session, the PRC will provide the underlying statutory framework for the implementation of potable reuse.

• The PRC will provide leadership in developing the regulatory framework for implementation of potable reuse as an alternative water supply option (right water, right time, and right place).

Guiding Principles

6

Deliverables

7

1. Proposed Legislation - Language/Outline of Legislation to provide State

Agencies the authority and direction to move forward with Potable Reuse

regulations and the structure needed to implement regulations to provide

potable reuse as an optional alternative water supply source.

2. Direct Potable Reuse Framework / Path Forward (Regulations) – Review of

existing regulations for the identification of limitations to Direct Potable Reuse

and suggested rule changes to allow Potable Reuse. Identification of the

overall process and a schedule to implement Direct Potable Reuse regulations.

This document will identify overall PRC process, stakeholder concerns and

solutions, and required next steps to implement Potable Reuse as option for

Florida's water suppliers

Florida Statues and Florida Administrative Code Chapters

The waters of the state are among its basic resources. Such waters should be managed to conserve and protect natural resources and scenic beauty and to realize the full beneficial use of the resource. Recognizing the importance of water to the state, the Legislature passed the Water Resources Act, Chapter 373, F.S., and the Air and Water Pollution Control Act, Chapter 403, F.S. (62-40.100 Declaration and Intent)

TITLE XXVIII NATURAL RESOURCES; CONSERVATION, RECLAMATION, AND USE

Chapter 373 – WATER RESOURCES

Part II – Permitting of Consumptive Uses of Water (ss. 373.203-373.250)

373.223 – Conditions for a permit – “Three-Prong Test”

373.250 – Reuse of reclaimed water – Reclaimed water is an alternative

water supply and is eligible for AWS funding

Florida Statues

TITLE XXIX PUBLIC HEALTH

Chapter 403 – ENVIRONMENTAL CONTROL

Part I – Pollution Control

403.064 – Reuse of reclaimed water – Requires consistency

between domestic wastewater permits issued by FDEP and

requirements for reuse contained in CUPs issued by the WMD

403.087 – Underground Injection Control Permitting - Requires a

permit for any stationary installation that is reasonably expected to

be a source of air or water pollution

62-610.554 Discharge to Class I Surface Water and 62-610.555 Discharge to Other Surface Waters

• Preapplication waste treatment shall result in a reclaimed water that meets, at a minimum, secondary

treatment and high-level disinfection.

• The reclaimed water shall not contain more than 5.0 mg/L of total suspended solids before application of

the disinfectant.

• Filtration shall be provided for total suspended solids control. Chemical feed facilities for coagulants,

coagulant aids, or polyelectrolytes shall be provided and maintained. Such chemical feed facilities may be

idle if the reclaimed water limitations are being achieved without chemical addition.

• Filtration is an important component of the wastewater treatment facility. By removing TSS before

disinfection, filtration serves to increase the ability of the disinfection process to inactivate virus and other

pathogens. Filtration also serves as the primary barrier for removal of protozoan pathogens

(Cryptosporidium, Giardia, and others). Addition of chemical coagulants generally increases the

effectiveness of pathogen removal.

• Total nitrogen shall be limited to 10 mg/L as nitrogen as a maximum annual average limitation.

Principal Treatment and Disinfection Requirements

24

• Drinking water standards.

• The parameters listed as primary drinking water standards shall be applied as maximum single sample permit limits. The primary drinking

water standard for asbestos shall not apply. The primary drinking water standards for bacteriological parameters shall be applied as the

disinfection standard as described in subsection 62-550.310(3), F.A.C., except that public notification requirements shall not apply. The

primary drinking water standard for sodium shall be applied as a maximum annual average permit limitation. The multipliers established in

subparagraph 62-600.740(1)(b)2., F.A.C., shall be used to establish maximum monthly and single sample maximum permit limits for sodium.

• All pH observations in the reclaimed water shall fall within the pH range established in the secondary drinking water standards.

• Additional reductions of pollutants which otherwise would be discharged in quantities which would reasonably be anticipated to pose risk to

public health because of acute or chronic toxicity shall be required.

• Total organic carbon (TOC) shall not exceed 3.0 mg/L as the monthly average limitation. No single sample shall exceed 5.0 mg/L.

• Total organic halogen (TOX) shall not exceed 0.2 mg/L as the monthly average limitation. No single sample shall exceed 0.3 mg/L.

• The treatment processes shall include processes which serve as multiple barriers for control of organic compounds and pathogens.

• Treatment and disinfection requirements imposed by Rule 62-610.563, F.A.C., are additive to other effluent or reclaimed water limitations

imposed by other rules (such as WQBEL limits designed to protect surface water quality, which are imposed by Chapter 62-650, F.A.C.).

• All ground water recharge and indirect potable reuse projects regulated by Part V shall implement pretreatment programs in accordance with

Rule 62-610.330, F.A.C.
