The City’s Wastewater Collection System (Public Sewer) is designed to convey the wastewater that is discharged from residential and commercial customers private sewer service lateral pipes to the Wastewater Treatment Plant or Water Reclamation Facility. Sewer customers are responsible for maintaining their own “Private Sewer Line” extending to the “Private Sewer Connection” on the Public Sewer Main.

OWNERSHIP AND LOCATION OF YOUR PRIVATE SEWER LINE

As shown in the illustration below, a private property owners “Private Sewer Line” extends from the home’s foundation and includes its connection to the “City Sewer Main”. Property owners in the City of Prescott are responsible for the maintenance and repair of the private sewer lines up to and including the tap into the City main.

BACKWATER VALVES

A backwater valve is a one-way valve that is installed on the building’s “Private Sewer Line” or the lateral sewer line. A properly installed and maintained backwater valve will prevent the lateral sewer line from backing up with sewage entering the building. The requirements for installation can be found in City Code Title III, Chapter 30, Section P3008. In support of this code, all structures connected to the City sewer system require an approved backwater valve.

PREVENTIVE SEWER LINE MAINTENANCE

The Wastewater Collections team is responsible for the implementation of the Sewer Line Preventative Maintenance Program. By using historical data and a variety of specialized cleaning equipment, the entire collection system is cleaned a minimum of every three years. A number of line segments are cleaned more frequently due to tree roots, fats, oils, grease and pipe condition. Maintenance needs of the collection system are determined by an internal video inspection of the pipes. These videos are then preserved in the City’s Computer Maintenance Management System (CMMS).

CONDITION ASSESSMENT

Wastewater Collection crews routinely inspect sewer main line conditions in the collection system utilizing Closed Circuit Television (CCTV) equipment. Video inspections are performed to evaluate existing pipe conditions, verify cleaning efficiency, locate private sewer connections and provide justification for Capital Improvement Projects to repair or replace old and damaged sewer main lines.

FAQ

  • Not under normal conditions. The hydro-jet cleaning process utilizes a high pressure cleaning nozzle which actually creates a vacuum as it passes by your private sewer line.

  • Call Public Works Engineering Permit Technician at (928) 777-1269.  The information regarding what activities are permitted within a sewer easement is available in the city code.

  • Normally it can be located by visual observation. The sewer backwater valve is usually located near a 3” to 4”diameter sewer clean-out and is often 6” to 8” in diameter.  The sewer backwater valve may be located in the right-of-way at the edge of your property line or near the house.

  • No.  Manholes and clean-outs shall remain unobstructed to allow easy access by City Wastewater Collection crews only.

  • Contact Wastewater Collection at (928) 777-1630.

  • Routine maintenance of your private sewer line helps to prevent obstructions.

    Here are a few helpful tips to help prevent sewer back-ups:

    Do not put bulky paper or trash into the sewers through toilets or sinks.

    Do not dispose of fat, oil, or grease into the sewers through toilets or sinks. Food left on plates can have a lot of grease, so wipe plates off into the garbage. Do not put food scraps in the Garbage Disposal, e.g., InSinkErator. Cooking grease should be poured into a heat resistant container to cool and solidify before disposing in the garbage.

  • Check the yellow page listings in the phone book or contact the Yavapai County Contractors Association at (928) 778-0040.

  • A lateral sewer line is the privately-owned service sewer line which connects your home to the public sanitary sewer system.

  • Contact Wastewater Collection at (928) 777-1630 during normal business hours Monday thru Friday 7:00am to 3:30pm or (928) 777-1626 after hours, including weekends and holidays.

  • Immediately contact Wastewater Collection at (928) 777-1630 during normal business hours Monday thru Friday 7:00am to 3:30pm or (928) 777-1626 after hours, including weekends and holidays.

  • The plumbing system in your home is designed to prevent odors from entering the house by using a Liquid Seal Trap or P-trap.  The water in a P-trap will evaporate if the fixture is not used often.  Seldom used bathrooms, floor drains and utility sinks are common odor sources. The simple solution is to periodically pour water (one or two cups) into the drain to refill the trap.

  • The property owner is responsible for maintaining the private sewer line from the house to the city sewer main including any portion of the private line that is within the public right-of-way or easement.

  • All structures connected to the City sewer system shall be protected by an approved backwater valve, installed in the building drain.  All structures connected to the City of Prescott sewer system shall be protected by an approved backwater valve when additions, alterations, or repairs to existing structures are done.

  • It is there to allow City Wastewater Collection Crews access to the wastewater system for maintenance. The manhole likely existed before the house was built.
