Water Testing and Treatment in Katy
Not sure if your water is safe to drink? If your well water has never been tested—or smells like sulfur, tastes metallic, or appears cloudy—it’s time to schedule a professional evaluation. We offer EPA-compliant water testing for Katy-area homes and properties.
Testing includes checks for:
Coliform and E. coli bacteria
Nitrates and heavy metals
Iron, sulfur, and manganese
Hard water (calcium and magnesium)
pH and turbidity
Based on the results, we provide tailored treatment system installations:
Whole-house filtration systems
Water softeners
Iron and sulfur removal filters
Reverse osmosis drinking water systems
UV disinfection
Houston-area groundwater often carries mineral content from the Gulf Coast Aquifer, which makes filtration and treatment critical for long-term water safety.

For Katy landowners managing farms, ranches, or large green spaces, we offer irrigation well drilling and high-capacity systems to support year-round water needs.
Services include:
Irrigation well installation for crops or landscaping
High-flow pump systems
Timers and remote controllers
Agricultural system maintenance
Livestock watering solutions
A dedicated irrigation well lowers your water bills, conserves municipal water, and ensures reliable water access—even during drought.
Geothermal Well Drilling
Geothermal energy systems use underground temperatures to efficiently heat and cool buildings. We provide vertical geothermal well drilling for residential or commercial systems in Katy, giving you a sustainable energy source and long-term savings.
Local Knowledge and Experience Matter in Katy, TX
The city of Katy sits at the intersection of Fort Bend, Harris, and Waller Counties, making it one of the most rapidly developing regions in Southeast Texas. While parts of Katy are within city limits and receive public utilities, much of the area’s land is unincorporated and lacks city water infrastructure—especially west of the Grand Parkway (TX-99), along FM 529, and near I-10.
This rural-suburban mix makes private wells the best solution for water access on many properties. 77 Water Well understands the local soil conditions, depth to the Gulf Coast Aquifer, and permitting processes for each jurisdiction.

About Katy, Texas – A Growing Region Dependent on Groundwater
Katy, Texas, is a fast-growing city known for its strong community, top-rated schools, and balance of suburban convenience with rural space. With a population of over 21,000 within city limits, and tens of thousands more in unincorporated areas, Katy continues to expand along key corridors like I-10, FM 1463, and TX-99 (Grand Parkway).
Much of the area west and north of downtown Katy lies beyond city utility zones—making private water wells critical to daily life for families, ranchers, and landowners.
Katy’s terrain features clay-rich soil and sits atop portions of the Gulf Coast Aquifer, which offers consistent groundwater access—but often with high levels of minerals like iron and calcium. That’s why professional well construction and water treatment systems are so important here.
Whether you’re living in Old Katy, building west of Cane Island Parkway, or farming near Brookshire or Pattison, 77 Water Well provides the licensed support and clean water solutions you need.
