The Main to Junction 420 Reclaimed Water Project ( ID: 5267.046) will construct approximately 6,600 ft. of reclaimed water main. The project will start on Rio Grande Street adjacent to the ACC Rio Grande Campus and end south of Lady Bird Lake at Auditorium Shores. Reclaimed water is highly purified wastewater that is ordinarily discharged to the Colorado River. Once processed, it can be used by customers for nondrinking uses such as irrigation, cooling, toilet flushing and manufacturing. Using reclaimed water helps conserve our drinking water supply.
