Small Household Drilling Rig

Small Household Drilling Rig: Your Reliable Partner for Clean Water, Anywhere.

This machine is for drilling a water well when you need to go deep, but don't need a full-sized commercial rig. It's built around a single-cylinder diesel engine, a hydraulic rotary powerhead, and a tripod derrick. You can think of it as a scaled-down, essential version of the rigs used for geothermal loops or deep irrigation wells.

Here are the numbers that define what it can do:

It's designed for a maximum drilling depth of 120 meters. For a reliable domestic water well, that's typically more than enough.

You can drill a hole between 100mm and 200mm in diameter, depending on the drill pipe and bit you fit. The standard setup is for a 150mm hole, which fits a standard 4-inch well casing.

The rig itself weighs about 750 kilograms. It's mounted on a trailer, so a medium-sized farm truck or tractor can tow it to the site.

The hydraulic powerhead delivers 3,500 Newton-meters of torque. This is the force that turns the drill string. It's enough to grind through clay, sand, gravel, and soft rock layers.

Running the diesel engine and hydraulic pump under load uses about 2.5 liters of fuel per hour.

What it's meant to drill through:

The system is effective in cohesive soils like clay, loose soils like sand and gravel mixes, and fragmented soft rock. It is not a hard rock drill. If you hit solid granite or basalt, progress will be very slow and will damage the drill bits. Knowing your local geology-or drilling a small test hole first-is the best way to confirm it's the right tool.

How it works on site:

You tow the rig to the location and level it. The tripod derrick is raised mechanically.

The diesel engine powers a hydraulic pump. This pump drives the rotary powerhead, which turns the drill pipe and bit.

As it drills, you pump water (or a thin clay mixture) down the center of the drill pipe. This "drilling fluid" comes back up the outside, carrying the cuttings to the surface and keeping the hole stable.

You add 1.5-meter sections of drill pipe as you go deeper. When you reach the required depth or a good water flow, you pull all the pipe back out, install the well screen and casing, and develop the well.

The practical costs and commitments:

The main cost to run it is the diesel fuel. At 2.5 liters per hour, a 30-meter well might take a day and use 20 liters of fuel.

It requires basic mechanical skill. You need to be able to check engine oil, grease fittings, and recognize when a hydraulic hose connection is leaking. It's not complex, but it's not a household appliance.

You need a water source nearby for the drilling fluid circuit. A pond, stream, or a large tank of water is part of the setup.

Common questions we get:

How fast does it drill?In clay, maybe 6-8 meters per hour. In sand, it can be faster. In gravel or soft rock, it will be slower, perhaps 2-4 meters per hour.

How many people are needed?Two people can operate it safely and efficiently.

What about spare parts?The engine is a common brand (like Changchai or similar). Hydraulic hoses, fittings, and drill bits are wear items you should have on hand. We provide a list of recommended spares with each machine.

To see if this rig fits your plan, we need to know:

What is the primary material​ you expect to drill through? (e.g., "sandy soil with some small stones," "red clay," "weathered sandstone")

What is your target depth​ for water?

What is the diameter​ of the well casing you plan to install?

With this, we can tell you if the machine' torque and flushing capacity are a match, and recommend the right drill bit and pipe setup from the start.

Where It Makes a Difference:
• Rural Homesteads & Farms: Providing self-sufficient water for household use, livestock, or crop irrigation.

• Remote Construction Sites: Establishing a temporary water supply for workers and equipment.

• Small Communities & Disaster Relief: A rapid-response solution for creating essential water access points.
