On Jan. 9, the City of Irving began construction on the replacement of a 48-inch diameter wastewater line and a 36-inch diameter wastewater line that run along the east side of Riverside Drive between Northwest Highway and Las Colinas Boulevard.
The project is part of the $27.6 million Cottonwood and Hackberry Creek Wastewater Interceptor Project. The wastewater mains have exceeded their life expectancies, and the surrounding area now requires increased capacity due to residential and commercial growth.
During the initial stage of the project, a new 60-inch diameter wastewater line will be constructed primarily underneath the existing median of Riverside Drive. Once the new line is in service, the existing wastewater lines will be filled with cementitious material and abandoned.
The project will use a process called “microtunneling,” a trenchless construction method, which will minimize impacts to residents and to vehicular and pedestrian traffic along Riverside Drive.
The project is currently estimated to be completed in the summer of 2024, weather permitting.
