Regional Water District to launch sewer transfer pipeline project in McKinney

McKinney residents will see construction of a new sewer transfer pipeline begin along Wilson Creek in 2022.

The project is crucial to continuing to meet the growing needs of McKinney and Prosper, said Paul Grimes, McKinney city manager. However, this will be “disruptive”.

“[Our staff] are trying to mitigate some of the impacts, but it sure won’t be pleasant, ”said Grimes. “We certainly urge people to be patient and understand that this is really progress. And you have to have these things if you like to have water and sewage, which we all do.

In September 2020, the North Texas Municipal Water District hosted a virtual briefing on the 6.4 Mile Sewer Transfer Pipeline Project. Work on the pipeline will begin near the old McKinney landfill and then extend northwest to south of SH 380 and Ridge Road, the presentation said.

Scott Hoelzle, sewage transportation system manager for the NTMWD, said this location will minimize the overall length and depth of the pipeline as it will follow the creek.

“If you didn’t follow the streams, you would end up traveling more across the country and ending up with really deep pipelines,” Hoelzle said.

Population projections show McKinney and Prosper are growing rapidly, Hoelzle said, and the new pipeline will help the district “stay ahead of that growth.”

“This will meet the long term needs of McKinney and Prosper,” Hoelzle said. “This will take some of the flow out of the city’s existing lines and put it in the neighborhood lines. “

The pipeline is an NTMWD project, but the district needs to work with cities as work progresses, Grime said. Ultimately, the pipeline will be operated and maintained by the district. The project is expected to cost around $ 38 million, Hoelzle said.

Design work for the pipeline is underway and construction is expected to begin in the second quarter of 2022. Work is expected to take about two and a half to three years with construction in three phases, Hoelzle said.
