CONDITION ASSESMENT FROM 6” TO 72’
In 1993, the District began its first video condition assessment of the 272 miles of District sewer pipes. It takes about 2.5 years to inspect all 272 miles of pipe. The entire District has been inspected more than 11 times since the beginning of the inspection program. The information collected has allowed Oro Loma to design cost effective rehabilitation and replacement programs, as well as place sewer lines on the proper cleaning schedules.
The District continues to focus on video inspection and currently has two video inspection vans that can inspect sewer lines from 6” up to 72” in diameter. The District has multiple camera and transporter combinations that enable the crews to select the best combination for the task.
The District uses the most advanced software programs available to collect and store the video inspection reports. The reports include not only still pictures of the sewer lines, but also detailed descriptions of the lines’ conditions and locations of the inspection sites. The information is continuously added to the database so that the District has a complete picture of the sewer system’s condition and can access the data by multiple factors including date, address, map coordinates, and task performed.
The video equipment and associated software program add to the District’s other top-of-the-line preventive maintenance equipment that includes a continuous rodder (a large root cutter that clears pipes), a vacuum truck (for removing heavy debris), and three hydro jetters (high pressure water jets that clean the pipes).
A crew of seven dedicated employees operates this equipment. The tools would be useless without the crew’s knowledge and expertise.
