Implementation Plan <br />Cleaning Operation <br />Houston & Harris PCS Inc. uses Vactor 2100 series combination cleaning units. Eighty <br />gallon per minute water pumps and high output positive displacement blowers remove all <br />levels of debris, Each truck is equipped with a variety of cleaning nozzles as well as chain <br />flails and warthog rotating nozzles to remove roots, and heavy deposits. Crews have been <br />trained to use the proper nozzle for any situation they may encounter, be it normal sewer <br />grit, roots, grease or mineral deposits. We also have root saws and milling tools to remove <br />large roots, protruding taps, etc. when encountered. <br />The cleaning operation follows the same methodology as the CCTV portion. Beginning at <br />the top of each area and continuing downstream until completion of all the line segments. <br />Hydro - washing crews work closely with the CCTV op yatQia..to,.,ensure- ,the- cleaning <br />operation is accomplishing our goals of providing the proper environment for the camera to <br />clearly document all defects, laterals and manholes in the inspection area. All vehicles and <br />operators are linked via phones /radios for rapid communication as well as trained to work <br />closely while simultaneously performing their specific tasks. A cleaning log is generated to <br />better aid with ongoing operation and maintenance services. <br />Utilizing the combination units is advantageous for working quickly through a system to <br />remove debris as it builds up and not just push it down the line or rely on traps which can <br />often let debris pass through. By removing debris from the system directly into the debris <br />tank, potential spills from contaminated water or solids are eliminated. <br />In order to provide maximum efficiency, Houston and Harris coordinates cleaning and video <br />services. Maps are reviewed regularly by both the cleaning and video operators. <br />Coordination of tasks such as, manhole locations, safety and traffic needs, as well as, debris <br />and flow are regularly communicated across both services by the operators, <br />City of Santa Ana Bid #13 -020 <br />Closed Circuit Television (CCTV( Inspection of Sanitary Sewers <br />21831 Barton Road <br />Grand Terrace, CA 92313 <br />909.422.9990 P 909422 -0841 F <br />CA #884187 <br />
