No Sewer & 60 Miles Out of Town: Remote Water Source Yields Piloting Challenges on the West Texas Plains
The City of Lubbock, Texas is conducting a program to connect to and utilize a new water source, Lake Alan Henry (LAH). This water source will be used to supply a new water treatment plant with an initial capacity of 15 mgd (57 Ml/d), expandable to 50 mgd (190 Ml/d) in the future....
Project Delivery Theory and Case-History Application
The optimal project, and construction, delivery method depends on application specific drivers. One important step in the delivery process is the selection of a Program Team (Prime Engineer). A case study for one method called Construction Manager at Risk (CMAR) is discussed including end user benefits and incentives....
Capital Cost for Phased Expansions for Brackish Groundwater Desalination in Texas
This paper presents the capitol cost for a phased expansion for the San Antonio Water Systems ( SAWS) program to integrate 30 million gallons per day of desalinated brackish groundwater into their overall water supply strategy. The Brackish Groundwater Desalination (BGD) program is anticipated to be constructed in three phases. Phase one will del...
Startup and Initial Operations of the Saws Brackish Groundwater Desalination Project
San Antonio, along with many parts of Texas is experiencing double digit growth rates every 10 years. San Antonio Water System (SAWS) must be able to provide adequate water supplies in order to meet this growth. SAWS, currently, gets the majority of their drinking water from the Edwards Aquifer, but water levels are decreasing, resulting in limitat...
Initial Performance of Membrane and Remineralization Processes for the Saws Brackish Groundwater Desalination Plant
At its proposed buildout capacity of 30 MGD, the SAWS BGD project will be the largest municipal RO treatment facility in the state of Texas and one of the largest in-land potable desalination facilities in the United States. This is the only municipal RO treatment plant in Texas that uses a three-stage RO system with an overall feed water recovery ...
