Sewer Sewer Basins
Age of Infrastructure Infrastructure greater than 50 years old should be considered for replacement during reconstruction. Policy and Design Criteria The following are key policy and design criteria applicable to the study area as provided in the City of Fort Worth Installation Policy and Design Criteria for Water, Wastewater, and Reclaimed Water Infrastructure and should be considered. z Parallel sanitary sewer lines for wide paved streets: The City criteria states that sanitary sewer service lines exceeding 55 linear feet is not permitted and will require a sanitary sewer line extension as long as the installation is not prohibitive due to topography, depth, and geometry required to meet TCEQ design standards. In segments where the ROW exceeds 110 linear feet, sanitary sewer service lines exceeding 55 linear feet are likely and therefore sanitary sewer line extension should be considered. z Minimum sanitary sewer line size: The City criteria states that the minimum size for any public gravity wastewater collection main shall be 8-inches. Up-sizing existing sanitary sewer lines to 8-inch or greater should be considered as the corridor is reconstructed.
The study corridor spans two sanitary sewer basins with Sycamore Creek Basin west of the East Berry Street/Freddie Street Intersection and Village Creek Basin to the east. Sewer Basins are areas that follow the drainage features within a service area for the City’s primarily gravity flow system and are utilized in hydraulic modeling of the sewer system. Through master planning and modeling efforts, the sanitary sewer lines identified within the sewer basins are sized to meet wastewater flow estimates from land use projections. Sanitary sewer modeling should be considered to adequately size the sanitary sewer mains for future density. Pipe Material Pipe material utilized within the existing system range varies from Reinforced Concrete Pipe (RCP), Polyvinyl Chloride (PVC), Ductile Iron (DI), Cast Iron (CI), Vitrified Clay Pipe (VCP), High Density Polyethylene (HDPE), and Fiberglass Reinforced Plastic Pipe. Vitrified clay pipe, which is prone to roots and costly when repairing has been identified just west of Riverside Drive and at the Cobb Park, Bishop Street, Village Creek Road intersections. VCP sanitary sewer line replacement from manhole to manhole should be considered as the corridor is reconstructed.
