The pilot scale demonstration confirmed the soundness of the technology for this application This proposed contract provides a full. scale inspection of M280 the older West Fork interceptor to set a benchmark of the pipeline condition and to identify locations of potential critical failures The inspection will Logname: 60WEST FORK MALCOLM PIRNIE Page 1 of 2 be performed with the line in service and includes sonar laser and television data The laser scans will reveal the remaining pipe wall thickness the sonar scans will map debris accumulated in the pipe and the television data provides visual information on the condition of the system The 46-year old pipeline M280 will be inspected from the old Riverside Waste Water Treatment Plant to the VCWWTP In conjunction with the pipeline inspection the contract services include additional professional services related to corrosion and odor control at the VCWWTP and within the sanitary sewer approach mains These services include an evaluation of chemical corrosion and odor control methodologies that are expected to extend the operational life of the pipelines and the VCWWTP and to reduce the generation of odor in the pipelines and at the wastewater treatment plant. In addition to contract costs $20 000 00 is included for staff support.
