CLEANING AND PRELIMINARY INSPECTION Burlingame must furnish all labor, materials, and equipment necessary to remove foreign materials frorn the Sanitary Sewer lines prior to inspection by closed-circuit television (CCTV). Burlingame must lease or own sewer -cleaning equipment. Following is a list of cleaning equipment that will be allowed or not allowed depending upon the application: A. High -Velocity Hydraulic (Hydro -Cleaning) Equipment: All high -velocity sewer cleaning equipment shall be constructed for ease and safety of operation. The equipment shall have a minimum working pressure of 2000 psi at a 30-gpm rate. The nozzles shall be capable of producing a scouring action, in the lines designated to be cleaned, to remove debris and sand from the flow line. Equipment shall also include a 2 high -velocity gun for washing and scouring manhole walls and floors. The gun shall be capable of producing flows from a fine spray to a solid stream. The equipment shall carry a nominal 600 gallon minimum water tank, auxiliary engines, pumps, and hydraulically driven hose reel. The equipment shall have a minimum of 650 feet of high-pressure hose. B. Hydraulically Propelled Equipment: Sewer balls or movable dam shall not be used. C. Root Removal Equipment: Chain flail nozzles shall be used for root removal. No chemicals will be allowed for use in root removal. SS -07. SANITARY SEWER CLEANING The designated Sanitary Sewer sections shall be cleaned using hydraulically propelled, high -velocity jet equipment. Selection of the equipment used shall be based on the conditions of the lines at the time the work commences. The equipment and methods selected shall be in accordance with Section SS -06 of these Standard Specifications. The equipment shall be capable of removing dirt, grease, rocks, sand, and other materials and obstructions from the sewer lines and manholes. If cleaning of the entire section cannot be successfully performed from one manhole, then the equipment shall be set up at the destination manhole and cleaning attempted again. SS -08. CLEANING PRECAUTIONS During sewer cleaning operations, precautions shall be taken in the use of cleaning equipment, so as to prevent damage to the existing pipe and manholes. Care must also be taken to prevent flooding of houses and toilets. Burlingame is responsible for cleaning of any flooding incidents to properties that occur during these operations. SS -09. MATERIAL REMOVAL All sludge, dirt, sand, rocks, grease, roots, and other solid or semi-solid material resulting from the cleaning operation shall be removed at the downstream manhole of the section being cleaned. Passing material from manhole to manhole will not be permitted. SS -10. DISPOSAL OF MATERIALS All solids or semi-solids resulting from the cleaning operations shall be removed from the site and disposed of at the Burlingame Wastewater Treatment Plant, located at 1103 Airport Blvd, Phone # (650) 342-3727. The Treatment Plant will need one day advance notice that the Burlingame will need to dump. Prior to dumping, Burlingame shall have dewatered the material accumulated from cleaning operations. SS -11. ACCEPTANCE OF SERVICES Acceptance of Sanitary line cleaning shall be made upon demonstration, through the television inspection, that the line has been cleaned sufficiently to allow determination of its condition. Costs for Sanitary line cleaning shall be included in Burlingame's unit price for television inspection. No additional compensation shall be made. N SS -12. TELEVISION (CCTV) INSPECTION Burlingame shall furnish all labor, materials, and equipment necessary to perform closed circuit television inspection, in color, of the Sanitary lines listed. The inspection shall be done one line section at a time and the flow in the section being inspected shall be suitably controlled as specified. SS -13. CCTV EQUIPMENT The television camera used for the inspection shall be one specifically designed and constructed for operation in connection with sewer inspection. It shall be a color camera, operative in 100 percent humidity conditions and shall have a 360 -degree radial view rotating head. Lighting and camera quality (3 lux) shall be suitable to allow a clear in -focus picture of a minimum of six lineal feet of the entire inside periphery of the sewer pipe. Lighting for the camera shall minimize reflective glare. To insure peak picture quality throughout all conditions encountered during the survey, a variable intensity control of the camera lights and remote control adjustments for focus and iris shall be located at the monitoring station. Focal distance shall be adjustable through a range from six inches to infinity. Continuously displayed on the monitors shall be: (1) date of the survey, (2) number designation of the upstream and downstream manholes corresponding to the line section being surveyed, and (3) a continuous forward and reverse readout of the camera distance from the manhole of reference. The remote reading footage counter shall be accurate to 2/10 (two-tenths) of a foot. The camera, television monitor, and other components shall be capable of producing a minimum 500 -line resolution color video picture. SS-14.CCTV OPERATION The camera shall be moved through the line in either direction at a uniform rate, stopping when necessary to permit proper documentation of the sewer condition. In no case will the television camera be pulled at a speed greater than 60 (sixty) feet per minute. Manual winches, power winches, TV cable, and powered rewinds or other devices that do not obstruct the camera view or interfere with proper documentation of the sewer conditions may be used to move the camera through the sewer line. A self-propelled tractor unit may be necessary for lines with only one entrance access or to prevent set up at high traffic intersections. As the camera approaches a lateral connection or substantial defect, the camera progress shall be halted and the camera lens panned to further view the lateral pipe and connection or defect to thoroughly evaluate its condition. A. If during the inspection operation, the television camera will not pass through the entire line section as a result of offset joints, broken pipe or other obstructions, then the Burlingame shall set up his equipment so that the inspection can be performed from the destination manhole. If the camera then fails to pass through the entire line section, the Burlingame shall immediately notify the Town. In the case of submerged lines or sags, Burlingame shall block the upstream manhole(s) and vacuum clean or jet flush the line and proceed with the television inspection. In the event Burlingame is still unable to televise the entire line and has demonstrated to the Town that every reasonable effort has been made to clean the line for inspection, or to reverse the camera path, then the Burlingame shall move on to the next set up. In such case, Burlingame may bill the Town at the appropriate per ft. rate for 50' minimum for each such set-up. This must be approved by Town representative. However, the 4 Town reserves the right to perform spot repairs to the line and have the Burlingame re- inspect the line. Reverse taping segments shall be checked for total coverage of manhole to manhole runs. B. In the event sewage line flows are too great to allow inspection or to be plugged at the upstream manhole(s), then Burlingame shall coordinate with the Town to reschedule television inspection during low flow periods such as early morning (i.e., between midnight and 5 a.m.). C. In the event the section being televised has substantial flow entering the sewer between manholes, such that inspection of the sewer is impaired, the Burlingame shall coordinate with the owner to have the flow temporarily stopped and/or reschedule television inspection of the particular section to a time when the flow is reduced to permit proceeding with the television inspection. D. When manually operated winches are used to pull the television camera through the line, walkie-talkie radios or other suitable means of communication shall be set up between the two manholes of the section being inspected to ensure good communications between members of the crew. E. The importance of accurate distance measurements is emphasized. The accuracy of the remote reading footage counter shall be checked periodically by use of a walking meter, roll -a -tape, or other suitable device. The accuracy shall be satisfactory to the Town representative. F. Should any DVD or section thereof prove to be unsatisfactory to the Town representative, the Town may request part or all of that DVD be televised again. SS-15.DOCUMENTATION The following listed documentation shall be provided and the cost for such shall be included in the Burlingame's unit price for television inspection. No additional compensation shall be made. A. Television Inspection Reports (Logs): The Burlingame shall keep electronic location records that clearly show the location, in relation to the reference manholes, of each defect observed during inspection. A CD copy of such records will be supplied to the Town representative. Pipe defects, roots, grease buildup, infiltration, cracked laterals, and other miscellaneous abnormalities shall be located by footage and noted in the report. If possible, laterals should also be referenced by address (i.e., by person above ground following with radio and roll -a -tape). Burlingame will use the same code/defect description scheme that is in use for the City of Burlingame. B. Each report, on each section of line televised, will have a summary and evaluation as to the general condition of that section. Reports and DVD's shall be turned in at least quarterly. 5 C. Television inspection data will be supplied on DVD computer disks. The supplied data will be WINCAN. This shall be submitted with the corresponding CD copy of reports and DVD's. Data entry shall include: ID Number, Address Number, MH# From, MH# To, Page #, TV Date, Pipe size, TV Footage, DVD#, Code, Rating of pipe condition and Event Photographs. Each photographic image shall be saved in a JPEG file format and named with the footage of the event followed by the event (for example, defect BJCM at 107.9' would be named MH#B3-21001-107.9bjcm.jpg). The files shall be stored within a file folder named for the Upstream Manhole Number. D. An Index must be provided and alpha -numerically sorted in the following order: (1) Street name, and (2) upstream manhole number and (3) DVD number. In addition, individual DVD indexes are required for each DVD, to be located at the beginning of the log reports from each DVD. Individual DVD indexes are to be listed in the same order as televised. E. DVD Recordings: Burlingame shall furnish color DVD recordings. DVD's shall be labeled and individually numbered, beginning with number "FY 2006-07 #001".
