    Permitting, Water Quality & Data Management

    The Permitting, Water Quality and Data Management sections work collaboratively with one another as they are an important link between the monitoring requirements, efforts and the informed data analysis for assessing & reporting the quality of the water. Permitting is responsible for implementing all federal and state wastewater laws and regulations as Water Quality provides the monitoring efforts to meet the requirements.

    Staff Training & Development

    The Pima County RWRD Staff Training and Development Section, also located at the WES Center, is comprised of a training team which serves several areas of training and development for the department. The Training and Development staff provides timely training solutions to enhance the ability of all RWRD employees to effectively perform their job duties.
