Based on the results of the implementation kick off meeting(s), the sewer cleaning and video inspection will start on the task, area or block of footage the City provides. Cleaning of the sewer lines will start as per the specifications of the RFP. All sewers will be cleaned within 24 hours prior to CCTV inspection except as directed by City personnel. Cleaning shall include removal of grease, roots, debris, and other obstructions to facilitate the CCTV inspection. Our operator will use the appropriate nozzle or cutter head to accomplish the cleaning as required for each section of sewer, H & H has high velocity, water jet, root cutter, and a variety of other nozzles available to ensure the pipes are sufficiently cleaned to allow for the camera to pass and document structural and operational condition of each pipe. H & H is experienced with City supplied tablet PCs and infraMAP® software. These technologies will be used to record the location of the Gleaning operation and the conditions encountered for each section of cleaned sewer main, Being experienced and trained in the use of infraMAP® will ensure at the end of each day of work, database synchronization will occur at the City corporate yard facilities. Once a line is cleaned and within 24 hours, the video truck will do the video inspection of the line. Sewer main television video inspection will be done using WinCan software specifically designed for sewer inspection and video recording. The camera will have light sources to provide a clear picture of the entire pipe. At the end of each City assigned task, Houston & Harris will submit a hard drive with all the video, Win Can data base with PDF files and Jpegs. The operator will use the tablet with infraMAP® supplied by the City to record the location. Sewer Main Inspections An `accurate to within one foot per 1000 feet' cable footage counter will be used by Houston & Harris field personnel. This cable footage will be indicated on the monitor and recorded on the video. The date of the inspection, continuous forward and reverse readout of camera distance from referenced access hole, the upstream and downstream manhole with an arrow indicating flow direction, the size of the pipe, the name of the street, the iWaterlD, the time of day and the project location name as supplied by the City will be displayed continuously on the monitor and recorded on the video. The color overlay information will be adjusted to ensure legibility. The footage relative to the center of the manhole at the start of each run will be set to accurately reflect a center of manhole starting position of 0.00 regardless of where along the pipe and at what footage the run begins. The inspection will begin by recording with the view looking from street level down the manhole. Video recording will be uninterrupted until the completion of the inspection at the next manhole. Pipeline information will be displayed at the start of each run per the specifications. Video personnel will ensure prior approval before recording of video against the flow or passing through interim manholes. All H & H video operators exceed the two-year experience requirement. The pipeline section information will be displayed on screen and the operator will do a voice over at the start and end of each section information to record conditions. The audio narration will include identification of the sewer main location by street intersection location or street address, the City manhole number, inspection direction of upstream or City of Santa Ana Closed Circuit Television (CCTV) Inspection of Sanitary Sewers__.... __....
