For your safety we advise the following:

  • All crew members will wear photo badges, and drive marked vehicles with the SARP10 logo. NO ONE will be requesting entry into your home; however, we may need access to your yard. 
  • NO ONE will ask you for money, donations or fees.
  • Smoke testing will be performed to assess the sewer. The SARP10 program will blow smoke into the sewer system. 
  • If you or your children have respiratory problems like chronic asthma, emphysema or other respiratory ailments, take care to avoid direct contact with the smoke resulting from the smoke testing performed by the SARP10 crews.
  • To prevent sewer testing smoke from entering your home or apartment unnecessarily, run water in all of the drains for 1 minute a week prior to scheduled testing. 
  • This process has been approved by the EPA and safely used for 20 years.
  • The smoke will disappear quickly without leaving an odor or stain.
  • If you see sewer testing smoke inside your home, we recommend that you call the SARP10 information line at 901.452.2385 or your plumber.
  • You have the right to ask for the proper SARP10 identification or call the INFORMATION LINE to verify testing and servicing in your area at 901.452.2385.

Closed Circuit Cameras

To examine the condition of the existing sanitary sewer lines in the system, the SARP10 team is using Closed Circuit Television (CCTV). These cameras are mounted on tracks that crawl through the sewer pipes to give 360 degree video of each segment to document defects or significant debris or grease buildup in the line. The video logs, along with summaries of the defects for each line, are then analyzed to determine maintenance and rehabilitation priorities. Lines with significant debris, roots, grease, or other maintenance issues are addressed by preventative maintenance either by the city or a city-appointed contractor. Segments with structural issues are prioritized by severity and the most severe lines will be addressed by SARP10 during the rehabilitation phase of work.

Manhole Inspection

The SARP10 Team will be inspecting sanitary sewer manholes throughout the City. Manholes are the main way the sewer maintenance crews gain access to the sewer lines for cleaning and general maintenance. The main objective of the inspection is to identify and classify defects in the manhole structure. The majority of the inspection is performed with cameras or video equipment. Once the defects are identified the SARP10 Team can then prioritize the repairs and develop plans for corrective actions.

Sewer System Rehabilitation and Repair

There are a variety of techniques and technologies available to maintain, repair and rehabilitate the sanitary sewer collection system to reduce sanitary sewer overflows (SSOs) and backups. These technologies are applied to resolve the specific concerns in sewer segments identified through CCTV and other condition assessments.

  • Preventative Maintenance (PM) includes high pressure washing of the sewer pipe to remove accumulated debris and grease, cutting and control of roots with chemical retardants and other maintenance techniques to keep the sewers open and flowing. These techniques are primarily applied in structurally sound sewers.
  • Repairs are implemented when structural defects, such as a broken pipe, allow rainwater and soil to wash into the pipe, creating a blockage which then restricts the flow of wastewater.
  • Rehabilitation includes pipe renewal techniques such as installing a cured-in-place liner within a deteriorated pipe to restore structural integrity. This and other trenchless or minimal excavation technologies provide new life to an aging pipe.

These techniques are selected and recommended based on the potential for the defects within any sewer segment to contribute to an SSO or backup, and the cost-efficiency and effectiveness of PM, repair or rehabilitation.
