Greenridge Wastewater Treatment Plant Improvements

The City of Houston Public Works Department is constructing a new 3,650 sq ft sludge dewatering building at the Greenridge Wastewater Treatment Plant. Located at 6301 West Fuqua St in Missouri City, this facility sits within the Central Southwest area of Fort Bend County. The project involves new construction intended to handle specific wastewater treatment processes, with a total estimated cost of $28,000,000.

Parsons Water and Infrastructure serves as the design firm of record for this infrastructure improvement. The project is registered with TDLR under the facility name "Greenridge Wastewater Treatment Plant - Sludge dewatering building." TDLR completed the plan review process in April 2026, clearing the path for physical construction to begin. The filing indicates that work is scheduled to start in January 2027.

The construction timeline spans approximately two years, with the project scheduled to finish in February 2029. This duration is notably longer than the median scheduled build window of 201 days for similar new construction filings in Fort Bend County. The estimated cost of $28,000,000 places this project in the top quarter of costs for new construction in the county, significantly above the median estimated cost of $700,000.

The cost per square foot for this project is $7,671, which is substantially higher than the county median of $100 per square foot for new construction. This high intensity of investment reflects the specialized nature of wastewater treatment infrastructure compared to standard commercial or residential buildings. The project utilizes public funds and public land, aligning with its status as a municipal utility improvement.

The City of Houston Public Works Department has one other TDLR-registered project on record, the IAH WWTP Admin Building in Houston, valued at $16,000,000. The Greenridge project is part of a broader pattern of infrastructure development in the area, where other registered projects in the vicinity include various office renovations and new commercial construction. The surrounding neighborhood in ZIP code 77489 has a population of about 39,054, with a median household income of $74,097 according to U.S. Census estimates.

Stephen A Meyer is the registered accessibility specialist for this project. The TDLR status is listed as Review Complete, confirming that the regulatory prerequisites for construction have been met. The project will operate within a local labor market where the Fort Bend County unemployment rate was 5.1 percent in June 2026, a figure higher than the previous year.
