On-site Wastewater Treatment

Nearly 50 million people in the United States use a septic tank as the primary treatment system for household waste.  A properly functioning septic system (conventionally a septic tank and subsurface disposal trench, bed, or pit) is one of the most efficient treatment methods available.  However, the Arizona Department of Environmental Quality (ADEQ) identified onsite/septic wastewater treatment facilities as the overwhelming activity/facility contributing to water quality impairment in Arizona -- over 90% of the identified activities.  There is a need to educate onsite system owners and operators about the proper management of their systems and to educate the onsite wastewater treatment industry about proper design, installation, and maintenance practices. The University of Arizona Onsite Wastewater Education Program delivers training, publications, and expertise to Arizona’s onsite wastewater system operators, practitioners, and regulators.

Homeowner Irrigation Workshops

Basics of how to design, install, repair & maintain irrigation systems with hands-on components. Arizona landscapes feature many low water-use plants and opportunities to use drip irrigation. These systems are often neglected after installation causing additional maintenance costs and repairs. These workshops are often held as components of the Master Gardener workshops that take place in county extension offices.
