Water Distribution System Leak Survey

The Water Distribution Leak Survey program is conducted using the latest state of the art leak computers, the Fluid Conservation Systems’ DigiCALL or Tri-Corr 2001 with an outstation preamplifier-transducer system.  All of these correlators are manufactured by Fluid Conservation Systems of Milford, Ohio.  These leak detection surveys correlators have a proven record of achievement in locating leaks on water distribution systems under very extreme circumstances. M.E. Simpson Co., Inc. uses FCS equipment exclusively in its leak detection programs for water utilities.  Our experienced Project Team (M.E. Simpson Co., Inc. uses TWO trained technicians on each leak survey team) will use these devices, along with the S20, S30, or L-MIC electronically enhanced listening device, to survey the pipeline network.

Every hydrant and accessible valve will be used in the leak survey as a listening point to identify leaks.  For non-PVC pipes services are used on an as-needed basis to keep the distance between listening points less than five hundred feet (500’); for PVC pipes all accessible services will be listened to.  When a leak is detected correlation will be used to verify the existence of the leak as well as to pin-point it.  "Pin-Pointing" of the leak, as well as locating leaks that other methods fail to reveal, is also done with the FCS correlation equipment mentioned above.  These electronic instruments are microprocessor units that measure the time it takes the sound of the leak to travel from the leak to the point where the leak detection correlator is connected to the water line.  By connecting the leak correlator out stations to the water line at two locations bracketing the suspected leak, the correlator analyzes the time delay difference between the sound waves received at each outstation, thus giving the distance from the leak to each connection point enabling us to determine the exact leak location. 

Upon completion of the project, a written report will be submitted describing the information generated for your records.  Following is a description of the individual phases of this project.
