Analysis
The City of Grand Prairie's Wastewater Collection System Master Plan identified segments within the City's collection system that require additional capacity to accomodate current and future peak wet weather flow. The required improvements consist of approximately 10,447 linear feet of existing 8-inch to 18-inch wastewater mains to be replaced or increased in size to 12-inch through 18-inch pipe in various locations within the City. These City of Grand Prairie projects represent the next phase of an on-going infiltration/inflow reduction initiative that prioritizes wastewater pipeline segments for replacement. These are located within sub-basins that the City's Master Plan identified as having a large amount of infiltration/inflow.
Eight groups of pipeline segments have been identified to be improved and these segments are included in the 2019 CWSR Application for Wastewater Replacements - Various Locations:
- Clarice Street
- NE 31st to Hensley Drive
- SW 5th Street
- NW 7th to Tarrant Road
- Cottonwood Creek
- NW Dallas Street to Fort Worth Street
- Indian Hills Trunk Line
- Small Hill Area
The City is receiving a loan from the Texas Water Development Board (TWDB) for the replacement/rehab of these locations for wastewater lines which transports raw wastewater from parts of the City's wastewater collection system.
The TWDB loan, which is not to exceed $3,672,000, is classified as a "green project" and therefore features 15% loan principal forgiveness of $550,800.
