The City of Merriam identified a portion of its storm sewer system serving the Owen Heights subdivision (southwest of 47th Street and Antioch Road) as having a significant deterioration of corrugated metal pipes. BHC was selected to evaluate and prepare a drainage memo for the existing network, modify drainage easements and prepare contract documents. Sixteen storm structures and 15 storm sewer pipe segments were evaluated by on-site inspection. We also reviewed previously collected data to provide recommendations for rehabilitation and/or replacement, including storm system inspection and CIPP (Cured-in-Place Pipe). Legal documents were created to align drainage easements with the existing pipe network. Plans and specifications were prepared for construction.
