Installing a water well is a smart investment for homeowners seeking self-sufficiency, lower utility costs, and independence from municipal water systems. But drilling a well is more complex than digging a hole and dropping in a pump. Before you break ground, understanding these seven essential facts will help you plan properly, avoid surprises, and ensure your well serves your family reliably for decades.
1. Well Depth Varies by Location
The depth of your well depends entirely on local geology and the depth of the aquifer. In our North Houston service area, wells range from 80 feet in some parts of Harris County to over 400 feet in areas where the aquifer sits deeper. We review geological surveys and well logs from nearby properties to estimate the likely depth before drilling begins. Deeper wells cost more but often provide better water quality because surface contamination has farther to travel.
2. Permits and Regulations Are Required
Texas requires licensed drillers for all water wells, and many counties require permits before drilling can begin. Montgomery and Waller counties have specific setback requirements—wells must be located a minimum distance from septic systems, property lines, and certain structures. We handle the permitting process for you, ensuring your well meets all local and state regulations.
3. The Pump Must Be Properly Sized
Pump sizing is critical. An undersized pump can't meet your household demand, leading to pressure problems and premature failure from overwork. An oversized pump wastes electricity and can damage your well by drawing water faster than the aquifer can recharge. We calculate your peak demand—accounting for fixtures, appliances, irrigation, and future expansion—to recommend the ideal pump size.
4. Water Testing Is Essential Before You Drink
Even water from a newly drilled well should be tested before use. We test for bacteria, nitrates, pH, hardness, iron, and other common contaminants. If any issues are detected, we install appropriate treatment before you begin using the water. Never assume that a new well automatically provides safe drinking water.
5. Your Well Should Be At Least 50 Feet from Septic Systems
Texas regulations require minimum distances between wells and potential contamination sources. The most important is your septic system. A well too close to a septic drain field risks bacterial contamination from wastewater. We always verify property layouts and setback requirements before selecting a drilling location.
6. Well Casing Protects Your Water Quality
The casing is more than a structural support—it's a critical barrier against contamination. The casing extends from the surface down through any unstable soil layers and into bedrock or consolidated aquifer material. It must extend at least 12 inches above ground to prevent surface water from flowing directly into the well. Proper casing installation is one of the most important factors in long-term water safety.
7. Choose a Licensed, Experienced Driller
Not all well drillers are equal. Unlicensed or inexperienced drillers may cut corners on casing depth, cement seals, or pump placement that lead to premature failure or contamination. At 77 Water Well Inc., we're fully licensed by the Texas Department of Licensing and Regulation, and we've drilled hundreds of wells across North Houston. We stand behind our work with warranties and ongoing service support.
