WateReuse California is actively engaged in working with our appointed and elected officials to pass legislation and develop regulations that will accelerate the implementation of both non-potable and potable reuse. The depth and breadth of experience within the organization also makes us the go-to organization for communities who are advancing water reuse to meet local demand for water.

Sacramento, CA – California’s Office of Administrative Law (OAL) approved OAL File No. 2024-0624-02S – the Direct Potable Reuse Regulations – and filed with the Secretary of State on August 6, 2024. This is the next critical step in the evolution of using recycled water as a safe and reliable water supply for Californians. The regulations will take effect on October 1, 2024.
Sacramento, CA – Following years of research, collaboration, and public engagement, California’s State Water Resources Control Board is voting today to adopt new regulations allowing for direct potable reuse. Direct potable…
In 1918, the state of California developed the first water reuse regulations in the United States to help irrigate its booming agricultural sector. Since then, California has remained a global leader in water reuse. Today, California recycles over one million acre-feet of water each year to benefit people and the environment. That’s enough water savings to meet the indoor and outdoor needs of at least two million households! California communities are securing their water future by producing highly purified recycled water for drinking and recharging aquifers, as well as by expanding non-drinking water reuse for agriculture and irrigation, and recycling more water within buildings.

Alabama has a history of water reuse citing back to 1975 with reclaimed water being reused primarily for irrigation. The state’s rules allow for Class A and Class B water, with different reuse applications applying to each. These regulations also explain how to apply for permits for reuse. Alabama’s Department of Environmental Management oversees the state’s regulation of water reuse.
The State Water Resources Control Board (Board) regulates water quality in California. The Board also develops statewide regulations for recycled water – potable and non-potable, including onsite reuse. The Board also provides funding through loans and grant programs for recycled water. The Regional Water Quality Control Board issues site specific water quality permits. The California Department of Water Resources manages water supply, including overseeing water conservation, groundwater and surface waters.
Arizona has a long history of water reuse beginning in about 1926. As much as two-thirds of all treated wastewater generated in Arizona is reused for a variety purposes, including irrigation, environmental restoration, energy generation, and agriculture. Legislative authority for water reuse was granted to the Arizona Department of Environmental Quality (ADEQ) in 1999 and reclaimed water rules focus on protecting water quality and human health. ADEQ is currently revising Arizona’s rules governing the use of recycled water. The first installment of new rules, effective January 1, 2018, allow permitting for direct potable reuse. In the next installment of rulemaking, ADEQ intends to adopt more detailed DPR criteria. Arizona has no indirect potable reuse (IPR) regulations, but IPR can be done under separate ADEQ groundwater protection permitting regulations. Other than graywater use, there are no specific rules allowing onsite or decentralized water reuse in Arizona.
The Colorado Department of Public Health and Environment (CDPHE) has a reclaimed water program that is designed to promote water reuse in the state. The state’s Reclaimed Water Control Regulation was introduced in 2000. The regulation covers the use of reclaimed water for landscape and agricultural irrigation, fire protection, industrial, commercial, and urinal and toilet flushing. These uses correlate to three categories of water quality standards, additional filtration and disinfection treatment for specific uses, and treatment from localized treatment systems (“decentralized”). The state also runs grant programs, such as the Water Plan Grant fund established in 2018, to incentivize new water reuse projects.
Recycled water has been used for irrigation in Delaware for decades. The Department of Natural Resources and Environmental Control administers state regulations and permitting for the distribution of treated wastewater for irrigation.
Water reuse was established as a state objective in 1989 and the state has since created a supportive regulatory environment. Florida has regulations that specify requirements of how reclaimed water is to be treated depending on the use or application of the water. Approximately 820 million gallons per day of reclaimed water are used for beneficial purposes each year, including golf course irrigation, residential irrigation, agricultural irrigation, groundwater recharge and indirect potable reuse, industrial uses, fire protection, and wetlands.
The Florida Department of Environmental Protection is moving forward with Phase II of rulemaking to ensure proper regulation for implementation of potable reuse programs in the state of Florida. The rules amended in Chapter 62-610 F.A.C. Phase II Reuse of Reclaimed Water and Land Application will address updates necessary to be consistent with recommendations of the Potable Reuse Commission’s 2020 report “Advancing Potable Reuse in Florida: Framework for the Implementation of Potable Reuse in Florida” as required by Florida’s Clean Waterways Act of 2020.
The Watershed Protection Branch of Georgia’s Department of National Resources Environmental Protection Division (EPD) has a set of guidelines for Water Reclamation and Urban Water Reuse. The guidelines were revised in 2012 and encompass considerations, system and monitoring requirements, and design standards for urban water reuse in the state. The uses covered are industrial and non-potable reuse. In 2011, the state released Guidelines for Reclaimed Water Systems in Buildings for reuse water to be piped within buildings for flushing toilets and urinals and other approved uses. In In 2021, EPD released the state’s first indirect potable reuse guidelines. The guidelines are intended to help applicants navigate through the regulatory complexity of a potential indirect potable reuse project, help the appropriate programs within EPD coordinate with each other, and streamline the regulatory process.
Water in the State of Hawaii is recycled for a range of non-potable applications. In 2016, the Hawaii Department of Health revised its guidelines for water reuse, which include technical requirements and application processes for various qualities of recycled water, requirements to construct or modify a wastewater reclamation facility, and best practices for reuse of graywater.
Reuse Guidelines- Volume 1: Recycled Water Facilities: Volume 1 addresses technical requirements that must be met for the various qualities of recycled water as well as requirements to construct or modify a wastewater reclamation facility (WWRF).
Reuse Guidelines- Volume 2: Recycled Water Projects: Volume 2 covers the application process to use recycled water for purposes such as irrigation, dust control, cleaning, and fire-fighting and establishes best management practices that apply to the end user.
Guidelines for the Reuse of Graywater: These guidelines detail the acceptable uses of graywater, including discharge from showers, bathtubs, hand-washing lavatories, and washing machines, as well as considerations for design and system maintenance.
Hawaii Department of Health, Recycled Water Program: The Department of Health administers the recycled water program.
Idaho has been supporting reuse since 1988, and state Department of Environmental Quality (DEQ) data indicate that over 4 billion gallons of water are reused every year. Idaho has both reuse regulations and guidelines that include treatment and beneficial reuse of municipal and industrial wastewater. Water reuse by different types of land application facilities is allowed by state regulations. In 1988, Idaho’s Wastewater Land Application permitting rules were promulgated and guidance was developed. Idaho has a public advisory working group that meets periodically to advise guidance development and review existing and future reuse guidance. In 2011 reuse regulations were updated, and the name of the rules changed to Recycled Water Rules (IDAPA 58.01.17).
