Engineering Excellence Silver Award
American Council of Engineering Companies of Texas
The Aledo Wastewater Treatment Plant won a Silver Medal in the Water and Wastewater category in the 2014 Engineering Excellence Awards from the American Council of Engineering Companies of Texas.
This project expanded the city's wastewater treatment plant under challenging site conditions — a flood plain on one side and a steep bluff beneath an affluent neighborhood on the other. Our team reclaimed previously undevelopable land for the expansion by building a 50-foot-tall retaining wall anchored by 800 soil nails. The project doubled the plant's flow capability; provided capacity for future expansion; and met new TCEQ treatment standards.
The plant is also the first in Texas to use a microwave-powered ultraviolet disinfection system. The system replaces conventional disinfection, which uses potentially dangerous chlorine gas, and it will help the City save on operating and maintenance costs.
Our team finished on time and nearly 10 percent ($600,000) under budget.
