Irving: Investing in Our Future

Cottonwood and Hackberry Interceptor Microtunneling Project Continues

Since construction began on the Cottonwood and Hackberry Interceptor Microtunneling Project in January, the $26.7 million project has moved along swiftly.

Now 42% complete, the project has not been affected by wet weather, underground utilities or delays with the hot summer weather. The City of Irving’s Capital Improvement Program (CIP) has avoided what could have been a noisy and messy wastewater main replacement project by using a relatively quiet trenchless technology method called “microtunneling.”

Microtunneling minimizes impacts to homes, businesses, vehicular and pedestrian traffic. The process uses a circular tunneling machine to dig under the surface. As it does so, the tunneling machine sprays water as it moves forward, creating slurry that is moved out of the digging site and onto the street. From there, it is then converted into dirt and loaded into a dump truck to be removed from the construction site.

The Cottonwood and Hackberry Creek Interceptor Project includes replacing two existing 36-inch wastewater mains that have exceeded their life expectancy with a 60-inch main to increase capacity due to residential and commercial growth. Construction is primarily underneath the existing median of Riverside Drive.

As of summer 2023, crews have installed more than 1,000 linear feet of the anticipated 4,900-foot wastewater main pipeline. Once the project is complete, it will improve wastewater service for all residential and commercial properties north of State Highway 114. 

The Cottonwood and Hackberry project remains on schedule, and completion is expected in July 2024, weather permitting.

Motorists in the area are reminded that Riverside Drive is closed to one lane in each direction. Drivers are advised to seek alternate routes when possible and to slow down through construction zones. 

For questions on the project, contact CIP Engineering Inspector Darral Keys at (972) 822-1028.
