| Project Detail |
North Alamo Water Supply Corporation (NAWSC) located in Donna, Hidalgo County, Texas, intends to provide first-time sewer service to nine low-income subdivisions in its service area that were not included as part of the original phase of a project that brought first-time sewer service to an unincorporated area north of the City of Donna. The original project provided first time service to 401 connections within six colonias. Under the proposed action, NAWSC will service nine additional colonies and provide first time service to an additional 419 connections. To service the 419 connections, the project includes construction of a collection system and the expansion of the existing Donna Regional Wastewater Treatment Plant (WWTP) from its current capacity of 0.5 million gallons per day (MGD) to 0.99 MGD. This includes the design and construction to expand and improve the existing wastewater treatment plant by constructing a new aeration basin, onsite a plant lift station, two small backup drying beds, and making some small improvements to the existing chlorine contact basin to provide an additional two minutes of contact time. It will also include all the related piping, valves, electrical, instrumentation, and other miscellaneous work for a complete functional project as well as the design and construction of a collection and conveyance system to transport wastewater from the nine targeted colonias to the wastewater treatment plant including the construction of five lift stations, 24,530 load force (LF) of force mains, and 25,548 LF of gravity lines. |
