Sanitary Sewer Connection Records Overview

header illustration - link to

These pages show historical sewer connection information as archived by Pima County Regional Wastewater Reclamation Department database records. While these records are believed to be accurate, a field dye test is required to know connection status with absolute accuracy. Recent connection information may be available through the jurisdiction's development services.

Many valid connections are not shown on these pages. In these cases, our records indicate that further research is needed. When a connection is not found here, users should fill out and send to us the "Request for Verification of Sewer" form:

or telephone us at (520) 724-6602.

Three areas in Pima County are served by public sewers and not owned by Pima County Regional Wastewater Reclamation Department. The areas are the town of Ajo, Rancho Sahuarita, and Northwest Marana. For sewer verification in these areas, contact the following:

Ranch Sahuarita - Town of Sahaurita (520) 399-1105
Northwest Marana - Town of Marana (520) 382-1999
Ajo - Pima County Development Services (520) 724-9000

Connection data was collected from various agencies that administered portions of the sanitary sewage collection system over the years. In 1979, an Intergovernmental Agreement entered into by the Pima County Regional Wastewater Reclamation Department (PCRWRD) and the City of Tucson (COT) directed that PCRWRD become the sole authority of the sanitary sewer system. This new agreement transferred all of the COT's connection records to Pima County. Some of the data received during that transfer dated back to the early 1900s. For a complete history of the evolution of the sanitary sewer system in Pima County, see Sanitary Sewer History.

Our data comes from a number of different sources. Many of the records are very old; others have come to us second or third hand. Some inherited records are incomplete or inaccurate.

While we make every effort to provide the best information, we do not guarantee accuracy. Read our disclaimer prior to using information from our database.
