He sewer line extends from the restroom facilities to the downstream manhole connection. Replacement of the entire sewer line from the restroom structure to the manhole is required. Acceptable construction methods include directional boring or open trench installation. The replacement line must be installed at the proper grade to ensure adequate conveyance of solids, with a minimum slope of 1 percent required. Two lateral connections currently discharge into the sewer line. One connection serves a bathroom (toilet/sink) and kitchen (sink only) located in the adjacent adobe building, as shown in the provided photographs. A new two-way cleanout is required for this lateral connection. The second connection serves a public restroom facility consisting of two sinks, four toilets, and two urinals. The restroom’s interior plumbing and associated sewer lateral are existing, newly constructed, and currently functioning. This existing lateral connects to the main sewer via a Y-connection at an unknown exact location. As part of this project, the contractor shall reconnect the replacement sewer main to the existing public restroom lateral at this Y-connection. Replacement or reconstruction of the restroom lateral or interior plumbing is not included in the scope of work. The completed work shall result in a fully functional sewer system with appropriate slope, durable materials, and compliant connections to eliminate infiltration, root intrusion, and structural deficiencies.
