About this file
This Addendum Table 1 is associated with the Rouge Valley Sewage Disposal System (RVSDS) SRF Project Plan for Phases 2C/3C Sewer Rehabilitation in Wayne County, Michigan. The document provides detailed technical specifications for sewer rehabilitation, specifically focusing on liner specifications for multiple interceptor segments across two designated areas (Area A and Area B). The table includes critical engineering parameters such as existing pipe geometry, assumed liner for design, and maximum allowable liner characteristics, including inner diameter measurements, roughness coefficients, and open channel capacities for various sewer segments.
The table presents technical data for five specific sewer interceptors with varying prevailing slopes ranging from 0.06% to 0.13%, and documents the proposed liner thickness and performance characteristics. The highlighted notation indicates a maximum cross-section reduction allowance, which includes considerations for grouting and voids. The data suggests a comprehensive approach to sewer system rehabilitation that maintains hydraulic performance while accommodating structural improvements. The document is dated 6/7/2024 and was prepared by Applied Science, Inc., indicating ongoing engineering assessment for the sewer rehabilitation project.
