Water Well Drills
Drill Down to Quality
Choosing a water well drilling rig requires careful consideration before signing on the dotted line. While price is the most common consideration for many people, there are quite a few other aspects to consider — some of which may outweigh the influence of price. When you choose Lone Star Drills you get much more than just a drill. With the purchase of any of our drills, we are committed to delivering value through quality, technical support and training.
- Quality: Don’t cut corners on materials and components if you want a drill that will perform well and last over time.
- Service & Support: Service is just as important as the product itself, so don’t skimp on the partner you choose.
- Training: Proper training is essential to the success of your operation, so work with a manufacturer who offers a safety and operational overview.

Water Well Drilling FAQs
How do I choose between mechanical, hydraulic and trailer-mounted water well drills?
Consider your drilling conditions and transportation needs. Generally, the larger the drill, the more power it will have to get through tough material and the greater depth you’ll be able to achieve. Here’s an overview of when to choose different Lone Star Drills water well drills:
- Mechanical water well drills: The smallest in the Lone Star Drills line, these models drill down to 200 feet in sandy and clay soils. They are ultra-compact, portable and ideal for carrying into remote drilling sites or transporting in the back of a small truck.
- Hydraulic water well drills: These drills provide expanded power and drilling depth, capable of reaching down to 300 feet in sand, clay and rock. Like our mechanical drills, they break down for easy transport.
- Trailer-mounted water well drills: These are the most powerful water well drill rigs in the Lone Star Drills line. They use hydraulic power to produce additional force and some models can drill down to 400 feet in a variety of soil and rock conditions. They are mounted on heavy-duty, lightweight trailers that can be towed with a small truck or ATV.
Should I choose a gas or diesel engine for rural or international water well drilling?
The answer depends on your power needs, maintenance discipline and jobsite factors including availability and convenience. Here are some considerations when choosing between gas vs. diesel for your water well drill:
- Power: Diesel is often preferred for increased torque, but many manufacturers increase the horsepower in gas engines to account for the difference.
- Availability and Cost: Look into whether gas or diesel is the primary fuel in the area. The answer will impact fuel availability and cost at the drilling location.
- Convenience: What type of fuel does other equipment on the jobsite use? Consistency across machines increases convenience.
- Maintenance: Diesel units tend to be more sensitive to dirt and debris and can be harder to keep running. Gas engines are more forgiving.
How deep can compact water well drills realistically drill in sand, clay, gravel or rock?
Lone Star Drills offers a range of compact water well drills with the smallest, the LS100, capable of drilling down to 100 feet in sandy and clay soils, and the largest, the LS400T+, able to reach down to 400 feet in sand, clay and soft and hard rock formations. When encountering hard rock such as quartzite, limestone, sandstone, granite or basalt, we recommend pairing one of our hydraulic water well drills with a down-the-hole (DTH) hammer to power through these formations down to 300 feet. Learn more about how to maximize productivity in tough rock formations in our blog.
What should be included in a complete water well drilling package before starting a remote job?
