Pflugerville City Council approved a $1.5 million preconstruction contract with PLW Waterworks for the project at an April 25 meeting.
At the same meeting, council also approved several contracts for engineering and construction management services totaling $17.9 million.
The first phase of the project will deliver a wastewater plant with a daily treatment capacity of 6 million gallons.
Construction is expected to begin on the facility this summer, with completion expected in March 2026, according to city materials.
The plant is projected to meet wastewater treatment needs for the Wilbarger and Cottonwood basins through 2030 once complete.
Two expansions to the plant are planned for the future, bringing its capacity to 12 million then 15.75 million gallons per day.
The total anticipated cost of the plant is $200 million; council will consider several more contracts in the coming months before construction begins.
