Putting in a point well, also known as a driven well, involves hammering specific components directly into the ground to access groundwater.
Essentially, a driven well is installed by hammering a sand point and pipe directly into the earth to tap groundwater that may be literally right under your feet. This method is a straightforward way to create a basic water source.
Understanding the Process
The core principle is simple impact driving. You assemble a series of pipes and attach a specialized tip called a sand point at the bottom. Then, using a driver or hammer, you pound this assembly into the soil until it reaches a water-bearing layer.
Key Component: The Sand Point
The reference highlights the crucial role of the sand point. It is described as:
- A perforated pipe section.
- Typically 24 to 60 inches in length.
- Features a heavy steel point at the very bottom, which serves as the water intake and helps penetrate the ground.
- Importantly, it is screened to keep out larger dirt particles, ensuring that mostly water enters the pipe.
Steps for Installation (Driven Well)
Based on the description of a driven well using a sand point, the process generally follows these steps:
- Select the Site: Choose a location where groundwater is likely close to the surface.
- Assemble the Point: Attach the sand point to the first section of pipe.
- Position: Place the pointed end of the sand point on the ground at the desired location.
- Begin Driving: Use a well driver or heavy hammer (often with a guide) to pound the pipe assembly vertically into the ground.
- Add Pipe Sections: As the assembly goes deeper, add additional sections of pipe using couplings.
- Continue Driving: Keep hammering until the sand point reaches the water table and penetrates sufficiently into the water-bearing layer.
- Test: Once believed to be in water, attempt to draw water up using a pump to confirm.
This method, focused on hammering the sand point and connected pipe, allows access to shallow groundwater sources.
