The Pima County Wastewater Management Department (PCWMD) has faced persistent and widespread odor problems associated with its wastewater conveyance system that conveys more than 60 mgd to two wastewater treatment plants (WWTP); Roger Road and Ina Road WWTPs which treat approximately 40 and 22 mgd, respectively

A number of measures have been taken over the years to reduce odor emissions including odor complaint tracking, field sampling, liquid phase chemical treatment, and several odor studies and evaluations. While these measures have achieved partial success, a comprehensive and satisfactory solution has remained elusive. This paper will present a study designed to evaluate the entire PCWMD conveyance system by a multi-pronged approach in an effort to solve PCWMD's conveyance system odor problems.
