,• . Page 2 The need for accurate and timely information about the condition of the City's sanitary sewer system is extremely important in the maintenance of the system. This information is needed to determine the extent of the system's repair and rehabilitation needs and the corresponding funding necessary to fulfill those needs. The standard method of obtaining this information is through the use of a video camera and videotaping equipment. A color video image enables a considerable amount of information to be recorded about the interior conditions of a sewer, especially smaller diameter sewers that cannot be walked or crawled through by an inspector. The information obtained is used by staff to develop sewer maintenance, repair and rehabilitation programs. The City established an annual sewer inspection program to inspect sewers each year beginning in 1996. In the first four years of this program approximately 240,000 feet (45.5 miles) of sewer has been inspected. The City recently completed the first year of a two year contract with Tele Scan, Inc. that began in Fiscal Year 2000-2001. The City's Engineering Division prepared a Request for Proposal to obtain proposals from firms to provide the sewer inspection for two years beginning in July 2000. The proposal was mailed to three firms that had expressed interest in providing this type of professional service to the City. At that time, Tele Scan, Inc. was the only firm to respond to the City's request for proposals. City staff's experience with Tele Scan has found them to be responsive to the City's needs and beneficial, given the knowledge they have developed of the City's sewer system in having performed sewer inspection services for approximately 10 years in Decatur. The basic scope of work in the proposed contract for Fiscal Year 2001-2002 is the inspection of approximately 120,000 feet of sewer. This is approximately double the yearly televising that has occurred in past years. Recent sanitary sewer collapses have pointed out the need for a more aggressive inspection of the City's sewers. This will enable repairs to be made in a more ordered approach as opposed to responding to an emergency situation. Additional work items in the contract include emergency inspections that occur as the result of sewer backups, a sewer collapse or other maintenance problems, special investigations, trenchless sewer rehabilitati.on of isolated sections of sewer typically less than 20 feet in length; manhole investigations and condition reports, and smoke testing to locate points of infiltration and illegal connections. POTENTIAL OBJECTION: There are no known objections to this resolution. INPUT FROM OTHER SOURCES: None
