Romero Visitor Center Sewer Line Inspection
Document Type
NOE - Notice of Exemption
Document Description
Department of Water Resources' San Luis Field Division will inspect the existing septic tank and underground sewer line for the State Water Project’s Romero Visitor Center. Waste from the septic tank will be pumped and taken offsite. A sewer pipe inspection robot with a camera will be inserted into the sewer line to trace its alignment. This will be done to determine if the sewer line location matches the original blueprint of the sewer line. While the alignment of the sewer line is being traced, the line will also be inspected for any potential breaks or leaks. If any breaks in the sewer line are detected, soil sampling will be conducted within an approximately 131,966-square foot work area. Soil samples will be collected using a protocol developed by the San Luis Field Division. A hand auger will be used to drill test holes along the sewer line. The test holes will range between 6 to 10 inches in diameter and will be up to 7 feet below ground. If the soil is too hard to use a hand auger, a backhoe will be used to dig test holes up to 30 inches long by 30 inches wide and 7 feet deep. Soil samples will be collected from all test holes. Once soil sampling is completed, all test holes will be backfilled and compacted to the original grade. The soil samples will be analyzed offsite. The State Water Project will benefit.
