Sewer Connections

Sewer Graphic Thumbnail
The private sewer pipe connecting a house or business to the public sewer in the street or alley is owned by the property owner, up to and including the point of connection to the public sewer pipe. It is the responsibility of the property owner to maintain the private pipe and protect it from damage caused by roots, grease, etc.

If you are looking for sewer connection information, there are two databases you can search by going to the Connection Records tab below and following the two links at the bottom of the tab.

If you still have questions, please go to Pima County Development Services website or call (520) 724-9000.

The Connection Data Provided Herein Is Not To Be Used For Bluestake Purposes.

Sewer connection information as determined by Pima County Regional Wastewater Reclamation Department can be found in two database records through the links below. While these records are believed to be accurate, a field dye test is required to know connection status with absolute accuracy.

Two areas in Pima County are not included in our records because they are not part of the Publicly Owned Treatment Works (sanitary sewer system and treatment plants) owned and operated by Pima County. The excluded areas are the Ajo area and the Rancho Sahuarita area in the Town of Sahuarita. For Rancho Sahuarita, call (520) 399-1105 for sewer verification.

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.

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.

Please note that the database contains mostly older connections made in the City of Tucson, and the process of receiving sewer cards dwindled and eventually stopped after 2000.

Search Window

Tips for using the document search tool:

  • Enter a search value in only one of the fields and click ‘Search’.
  • Using an asterisk symbol (*) at the end, beginning, or on both sides of your entry will show all records with the entry and anything else in place of the asterisk.
  • Example: In the Address field, entering RIVER* will show every record with an address that starts with RIVER.
  • To get the most records, use the asterisk (*) on both sides of your search.
  • Example: Placing and asterisk on both sides of *RIVER* will show every record that has the word RIVER somewhere in the address.

How can I get information about my sewer connection? Where is my clean-out located?

Sewer connections can now be searched online using our Connection Records database here. If you can’t locate your record, you can make a request for further research using the "Request Sewer Record" form provided at the same link or by sending an email to RWRDRecordsResearch@pima.gov

What if there is no record and I need to know if I'm connected to the sewer?

A dye test is needed to verify connection to the sanitary sewer system. Occasionally there is no record of a finalized sewer permit on file, because the permit was not recorded, not obtained, or not inspected.

Many lenders require proof of connection to the sewer. Without a finalized permit on file with Pima County a dye test is the only other form of proof.

Ordinance 2004-11, §13.24.200, G, Dye Testing

How much does a dye test cost?

A dye test costs $207 and if there is more than one unit to be tested at the same time each additional unit is $23. For example, a duplex would cost $230 if the owner decided to test each unit.

Ordinance 2004-11, §13.24.200, G, Dye Testing

How long does it take to get a dye test?

We ask that you give us two weeks leeway to get the dye test set up and performed. Our schedule is dependent on operations workload and emergencies come first.

What if I have a septic system and need information?

For septic system design questions, call Pima County Development Services at (520) 724-9900.

For records of existing septic systems, use this link or email buildingsafetyadmin@pima.gov

For recertification of existing septic systems, email buildingsafetyadmin@pima.gov

How do I get a permit to connect a house connection sewer (HCS) to the sewer system?

New connections to the public sewer require a Connection To Existing Sewer Permit application and payment of a sewer connection fee. If the physical connection is to a manhole or large sewer pipe, a Small Activity Construction Permit will also be required for inspection staff to observe the connection. If you are moving a connection point for an existing structure only, a Small Activity Construction Permit is required.

What if my connection to the public sewer (HCS) is damaged and needs repair?

Property owners are responsible for the maintenance, repair, and replacement of house connection sewers from the structure to the point of connection to the public sewer. In certain situations, RWRD may repair the damaged portion of the HCS located within the public right-of-way. Please contact the Conveyance Division through central reception at (520) 724-3400 for more information.
