The Airline Improvement District applied for and was awarded grant funds from the Texas Water Development Board to complete a Water and Wastewater Planning Study for the District area. The study was completed in July 2008 and showed the current state of sanitary sewer systems in the District at that time. The study, identified 85 million dollars’ worth of possible water and sewer projects and is used as a guideline to determine what projects are most viable and to apply for grant funds to design and construct projects.
