Evaluation of Sanitary Sewer and Drainage Systems for the High, Church, and Prospect Street Area
The Town of Stafford, Connecticut selected Weston & Sampson to evaluate sanitary sewer and drainage systems for the High, Church, and Prospect Street area. As part of the evaluation of 11,500 linear feet of roadway, drainage and sewer system, Weston & Sampson completed the following tasks:
- Manhole and catch basin inspections
- Television inspection of the project area
- Pipe inventory
- Smoke testing
- Cost analysis to examine rehabilitation methods (spot repairs, cured in place pipe, or full excavation)
In addition, Weston & Sampson completed a general assessment of the drainage system structures and a hydrologic and hydraulic analysis on the existing storm drainage system.
Based on the results of the sewer assessment, Weston & Sampson found that much of the sewer in the project area was in need of repair, rehabilitation, or replacement. Weston & Sampson recommended a mix of rehabilitation and replacement. Cost estimates for each sewer segment and the recommendations were provided. The recommendations and related cost, have been used to secure funding for the overall roadway, drainage and sewer improvements. To date, approximately 25 gpm of infiltration has been removed from this neighborhood sewer collection system.
Based on the results of the drainage assessment, Weston & Sampson found that the drainage system was undersized and recommended that as roads in the project area were reconstructed, new sewer and drainage systems should be installed.
Utilizing the results of the analysis, the Town of Stafford was able to secure a Community Block Development Grant to help redevelop the area.
