The Water Utilities Department consists of four divisions; Drinking (potable) Water, Wastewater, Pretreatment and Laboratory Services.  All department employees are committed to delivering a safe and abundant supply of potable water sufficient to meet the needs of each of our customers at the lowest practical costs.  Our utility also has the parallel mission of transporting customer wastewater to treatment facilities at the lowest practical costs. To that end, we remain vigilant in meeting the challenges of source water protection, water conservation, and community education.

Potable (Drinking) Water Division

The City of Garland purchases treated water from the North Texas Municipal Water District (NTMWD).  It is the responsibility of this division to manage and operate the distribution system that brings water to the residents and businesses of Garland.  ​For information regarding drinking water quality, click here.

Pretreatment Division

The Pretreatment division works closely with the wastewater division to prevent local businesses and industries from discharging harmful or difficult to manage chemicals into the wastewater treatment plants.  It is the responsibility of this division to inspect, test and investigate flows that contain harmful chemicals entering our wastewater system.

Laboratory Division

The Laboratory division provides testing services and data analysis for our wastewater treatment plants, the city’s health department and Garland Power and Light (GP&L).   This team of chemists and biologists are responsible for accurate testing procedures and timely reports to meet all state and federal regulatory requirements.
