LRWRA is responsible for maintaining 1,400 miles of sewer system, 32,000 manholes and more than 200,000 residential sewer line connections. Acoustic inspection uses sound to locate and characterize pipes based on the sound of flowing water. It is becoming a standard in managing infrastructure due to its cost savings potential. This method can help prioritize maintenance needs by avoiding needless cleaning of relatively clean pipes or repairs to pipes with only minor issues.
You will see LRWRA employees and vehicles which are clearly marked working at manholes in your neighborhood. Sound waves will be sent from a transmitter in one manhole to a receiver in a nearby manhole using a Sewer Line Rapid Assessment Tool, used to assess any blockages in the line. The sound waves can be heard outside the manhole; but, are not loud or disruptive. If a manhole is located on your property, the crews may need to access the manhole; but, will not need to enter your home. The actual test will take about five minutes and traffic interruptions will be minimal.
In order to efficiently maintain and clean the 1,400 miles of sewer system, LRWRA’s goal is to complete annual preventive maintenance on all residential sewer lines in the system. The inspection will target overflows relating to broken lines and blockages such as those caused by a buildup of roots and grease. The results of the inspection will determine the priority for cleaning.
