Water & Wastewater

Water Department

The Water Department operates and maintains systems for the production, storage, and distribution of potable water in accordance with requirements of State and Federal agencies. Operational activities are maintained on a 24-hour basis. The City contracts with and pays West Harris County Water Authority and Blue Bonnet Water Authority for water pumped from Harris, Fort Bend and Waller Counties. Infrastructure maintained and operated by this department includes mains, valves, fire hydrants, water taps and meters, water wells, elevated tanks, ground storage tanks and booster pump stations.

The City’s well system is looped to ensure residents are never without water, in the event that a well is not operating. The Water Department flushes fire hydrants on a monthly basis to keep sediment from forming at the end of the water lines. Citizens should contact the Water Department with concerns of water leaks, water quality, high usage, and low pressure.

The City of Katy has maintained a Superior Water District rating for the past 20 years and is dedicated to continuing this service to the citizens. The report below is a summary of the quality of the water we provide our customers.

Wastewater/Sewer Department

The Sewer Department is responsible for the operation and maintenance of the wastewater collection and reclamation systems. Wastewater generated by customers throughout the City flows through gravity mains to a series of lift stations where it is pumped to the Reclamation Center. There is currently one “master” lift station which pumps directly to the Reclamation Center, and 14 lift stations which serve various subdivisions to convey wastewater to a “master” lift station. At the Water Reclamation Center, wastewater is processed in accordance with State and Federal regulations. Reclaimed water is discharged to Buffalo Bayou. Activities in this department include emergency response to stoppages, routine cleaning and inspection of mains, pump and valve maintenance, laboratory analysis, and 24/7 operations of the lift stations and Reclamation Center.


The City of Katy Public Works Department provides 24-hour emergency services. To report emergencies after normal business hours, weekends or holidays, please call the Police Department at 281-391-4848 and the appropriate Public Works personnel will be contacted.
