How to properly drill a well in a well

Although it may seem strange, drilling a well inside an already-existing well is a useful way to improve water flow or gain access to deeper, more dependable water sources. If your original well is dry or not producing enough water for your needs, this method may come in handy.

It’s crucial to comprehend the procedure and acquire the required tools before you start. To drill within a well without damaging the existing structure, you need specific tools and a well-thought-out plan. You don’t have to start from scratch to improve your water supply if you take the proper measures.

We’ll take you through each of the crucial procedures for drilling a well inside a well in this guide. We’ll go over the necessary safety precautions, the drilling procedure, and preparation. Regardless of your level of experience doing do-it-yourself projects or well drilling, this post will give you the confidence you need to get the job done.

In order to guarantee a consistent supply of water, drilling a well requires meticulous preparation and accuracy. To prevent contamination and equipment damage, this process necessitates choosing the appropriate location, utilizing the appropriate tools, and adhering to safety regulations. You can successfully drill a well that effectively and sustainably meets your water needs by being aware of the procedures and following best practices.

Comparative characteristics of tanks

Before installing new equipment, you need to figure out what is better: a well or a well for a home. In times with one washing machine and seasonal garden maintenance, a deep tank of water was enough for a person. The pit here is dug to the level of underground and groundwater – a permanent aquifer 10-15 meters deep (including 0.5-2 m in the solid layer). That is, the filling capacity can be limited only by quicksand, which is expressed in the range from 300 liters per day to 600 l/hour. In order to increase the volume of liquid, further deepening the well does not make sense, since underground flows will restore the previous situation.

A well can be used in two ways: with a drainage pump or manually (with total independence from electricity and other equipment). Since the liquid is raised to a low height, the device can be operated on virtually any power source. Once the water has been pumped out, refill the tank to the desired level after a little period of time.

Nowadays, the biggest drawback of a well is contaminated natural water and air sources. Particularly close to rivers, lakes, and wastewater treatment facilities, substances that are not filtered by the soil can reach the aquifer at a depth of up to 15 meters. That is, it is worthwhile to periodically analyze the chemical composition of the water in industrial areas adjacent to cities.

Let’s now examine the distinction between a well and a well. In an artesian or sandy horizon, the depth here is determined by the level of water taken. It is roughly 20 to 50 meters in the first option and up to 100 meters in the second. Furthermore, the pit’s diameter is only 3.6–5 cm or 12 cm, respectively, rather than 0.5 m.

This is where the pumping apparatus gathers the water. In this instance, the pressure generated causes the shaft to fill continuously. As a result, the well never runs dry (its daily efficiency is between 3,000 and 5,000 liters). It’s also important to remember that the water is safer for human consumption because of better filtration brought about by the source’s deep depth. It is possible that the composition is deficient in manganese, hydrogen sulfide, and iron.

The locations of the tanks also differ from one another. The well must be at least 30 meters away from any source of pollution, per the regulations. These include baths, septic tanks, gutters, toilets, and composting. Slopes, ravines, and coastal regions close to natural bodies of water are also subject to restrictions. Drilling wells within a house is permissible as long as a 15-meter indentation is maintained.

If we compare the cost of a well versus another well, the second seems more cost-effective at first. For the first, a pumping station and a drilling rig are needed. Based on the estimate, this is a significant one-time amount for a large number of users. In the end, less money will be needed for concrete rings, pit excavation, soil removal, drainage, and well structure assembly. But in the future, the family might not have enough water or the water might not be of high quality. That is to say, in terms of supplying water to a house and yard as well as people’s health generally, a well nowadays frequently proves to be a more sensible solution.

It’s also important to discuss the differences in durability between a borehole and a well. It is impossible to forecast how full the tanks will be in either scenario. Both the human factor and natural changes justify this. For instance, adding new reservoirs to existing ones lowers the average amount of water that is available. However, well drainage is more typical. Although it is less common, silting or filter wear in a well can also cause this.

The rationality of installing a well in a well

Specialized equipment is used when drilling a well, whether it is in a house, another location, or both. Forming a pit (technological recess) might not take more than 30 minutes if this is a professional installation. Subsequently, a rigid pipe channel is installed down to the ground. In other words, the project’s estimated cost is determined by using the zero point, which is not the well’s bottom.

Working with virgin soil is preferred by most specialists. If we take a well example, we would have to construct a sump and fasten the pipe to the walls (rings). This is where the flushing fluid enters the recess. That is, the team will find it harder to solve the current problem in a constructive manner, and using the old tank will become more challenging.

Technological process

It is evident that drilling a well within a well is feasible. Let’s examine how to achieve this. However, you must first determine which tank is appropriate for work to be done. Every case is created independently because there are no rules or written guidelines.

Here, the following details ought to be mentioned:

1. Condition of well walls. The new design should not cause destruction of the rings or frame. To prevent this, inspection and elimination of defects and filling of cracks are carried out. The wooden channel is reinforced with additional strapping.
2. Ring alignment. If there are deviations, they indicate instability of the sand cushion. Here, a well for a well will not be the best solution, since after breaking through a new water flow can wash away the ring. This will result in the destruction of the walls and the pipe that is attached to them.

Strengthening the casing and the installed conductor are part of the installation work. In order to accomplish this, anchor bolts are inserted along four axes into the well’s sturdy walls. They have vertically aligned steel profile racks attached to them. To create an edge at two or three levels, the support strips are connected by rods, resulting in the creation of a square section. The upper ends are treated in the same way.

Using the conductor, the following operations are carried out:

• a point for the well is planned;
• vertical corners are hammered around it;
• the strips are welded together along the perimeter;
• the structure is rigidly fixed with ring binding.

Next, a conductor pipe is inserted into the well beneath the well. Its end ought to be level with the well frame’s exterior edges. Typically, backfilling occurs in the mine after drilling is finished. In this manner, the canal will be shielded from the abrasive effects of soil particles as well as the effects of wastewater and groundwater.

At last, the well’s top piping is installed inside the home. If not, the structure is referred to as a borehole. This enclosed dwelling has walls and a submerged bottom in the earth. This is where the pumping unit and shut-off valves are.

One can construct such a building in a variety of ways. In a pit that is up to 1.5 meters deep, the most basic of them is reinforced concrete or brickwork. The walls need to be further insulated if the groundwater is deep. Installing a completed caisson composed of plastic or metal is an additional choice.

Installing an adapter on the casing pipe is an alternative to piping. Although plastic can be used, steel products are preferable. It is then connected to a water supply channel that needs to be submerged in the ground. If a submersible pump that is lowered into the well is used, this solution becomes pertinent.

Establishing a well can yield a gratifying endeavor by offering a dependable supply of water for your home or landscape. You can guarantee a successful drilling process by using the appropriate tools and adhering to the correct procedures.

Prior to beginning, it’s critical to do extensive research, comprehend the local geology, and obtain the required permits. The durability and effectiveness of your well will also be greatly impacted by the use of high-quality tools and supplies.

Your primary concern should be safety at all times when drilling. Always wear safety gear, handle equipment with caution, and keep an emergency plan in place. Your well will continue to function well for many years to come with routine upkeep and inspections.

Patience and meticulous preparation are ultimately essential. Drilling a well can be a straightforward and fruitful process that gives you a useful resource for your house or garden if you take the proper precautions.
