As Missouri City sees community growth, city officials are working to expand its wastewater treatment plant to ensure infrastructure is keeping up with the demand.

Missouri City City Council voted May 6 to spend $3.26 million for a 12-acre tract of land near Hwy. 6 and Fort Bend Parkway Toll Road for future phases of the Mustang Bayou Wastewater Treatment Plant expansion project.

Current situation

City officials are wrapping up the $4.2 million Phase 2 of the expansion project, which will increase the plant’s capacity from treating 1.5 million to 2 million gallons per day.

This phase is funded by a variety of sources, including wastewater impact fees and tax increment reinvestment zone funding, and is anticipated to finish by June, Public Works Director Shashi Kumar said in an email.


The background

Beginning in March 2020, Phase 1 aimed to expand the plant’s capacity from 950,000 to 1.5 million gallons per day and was completed in June 2023, Kumar said.

Why it matters

The city continues to see rapid growth in the Mustang Bayou service area with the addition of new residential and commercial developments, including:
  • Dry Creek neighborhood
  • Parks Edge neighborhood
  • Fort Bend Town Center II and III
Kumar said the expansion is necessary to keep up with the continued growth in the area to support future economic developments and enhance residents’ quality of life.


“Infrastructure is the backbone for economic development—as the city continues to grow and reach build-out, a lot of investment is being made in both water and wastewater infrastructure projects in the coming years,” he said.

What’s next

Future Mustang Bayou Wastewater Treatment Plant expansion phases are under evaluation, so timelines haven’t been established, Kumar said.
