The City of Garland owns and operates two state-of-the-art advanced biological wastewater treatment facilities.
Wastewater is collected for each facility in two separate drainage basins, the Duck Creek Basin and the Rowlett Creek Basin. Wastewater is then received and treated at two separate facilities, the Rowlett Creek and Duck Creek Wastewater Treatment Centers.
The Rowlett Creek Treatment Plant serves the east side of Garland including the cities of Rowlett and Sachse. The Duck Creek Treatment Plant receives wastewater from the west side of Garland, and from portions of the cities of Dallas and Richardson and the City of Sunnyvale.
State certified operators continuously operate both facilities 24 hours per day, 7 days per week, 365 days a year.
