What is a sand well

In response to the inquiry concerning the characteristics of a self-sufficient water supply source on sandy soils, the following noteworthy aspects must be acknowledged:

• work is carried out to the level of the aquifer located under the clay in the sand layer;
• the maximum immersion depth of the drilling tool is no more than 50 m;
• drilling operations can be carried out independently using a manual or mechanized tool.

A sand well differs from an artesian (limestone) well in the following ways:

• significantly less depth, which can reach even 10 m;
• reduced volume of extracted water, amounting to 1 m3/h;
• use of cheaper casing pipes of smaller diameter (127 mm).

The locations of the aquifer could be anywhere from these:

• in a cavity formed by an underground stream. As a rule, in this option the flow rate is increased and the water is cleaner;
• in a fine-grained sand massif. In this case, siltation and a decrease in the service life are possible.

The amount of water that can be extracted and the amount of time that the pit can be used both increase with the thickness of the water lens. What is the service life of a sand well is a question that many people have. Reviews attest to the fact that its service life is no longer than ten years. This is a brief time frame that is appropriate given the total amount of expenses.

The following tools are used in the drilling of sand wells:

• a manual garden drilling rig. Has reduced productivity and requires increased physical effort;
• mechanical auger drill. Allows you to reach the aquifer in the sand layer in 24 hours;
• manual gasoline drill. Allows you to speed up and mechanize the process, as well as reduce costs;
• auger unit on a vehicle chassis. High-performance unit, allows you to reach the layer in a couple of hours.

Special filters must be used to guarantee the produced water’s purity and raise its quality to food standards.

Drilling a well for sand – reviews

Drilling an artesian well on your property is not always financially feasible. If you need a water supply source but don’t have enough money, drilling for sand is a good middle ground. In this instance, the drill tool will enter the aquifer and create a channel up to 30 cm in diameter. Reviews state that the water’s quality prevents it from always being fit for human consumption. It is appropriate, nevertheless, for household, irrigation, and technical needs.

There are several important benefits and several major drawbacks to a sand well. Numerous reviews attest to this. Let’s think about them.

Sand well – main disadvantages

There are drawbacks to this technique even though drilling in sandy soils is simpler and more profitable. Drawbacks:

• non-compliance of water quality with standard requirements. Sand layer – primary level of water purification. Fertilizers and herbicides from agricultural lands easily get into it;
• insufficiently deep pump immersion level. There is an increased probability of silting of the filter part of the casing pipe located near the surface. Due to the accumulation of silt, further operation becomes impossible;
• difficulty in cleaning and replacing the filter element. At depth, it is not possible to restore the filtering capacity of the mesh. The only possible option is to clean the filter due to the vibration of the operating pump;

• frequent failure of the pumping station. In the process of constant operation, with a decrease in the area of ​​the filter surface, the load on the pump increases. As a result of overheating, it burns out;
• reduced flow rate. Intermittent supply and reduced productivity are typical for casing pipes shallowly buried in dry soil. In any case, there is enough water to stably supply one house.

Now let’s talk about the benefits.

A dependable supply of water for gardening, cattle, or other purposes can be obtained by building a DIY sand well, which can be a satisfying project. You can save money and enjoy the satisfaction of having a self-sufficient water supply by building a practical and efficient well on your own with a few simple materials and tools. This tutorial will take you step-by-step through the entire process, making sure you know how to drill the well, pick the ideal spot, and install the required piping and filtration. With a little perseverance and work, anyone can complete this project, regardless of experience level with do-it-yourself projects.

Drilling wells for sand – the main advantages

The benefits of an independent water supply system draw many in spite of the drawbacks:

• acceptable level of expenses. Compared to drilling on limestone formations, the volume of expenses is less;
• the possibility of using small-sized drilling devices. This is convenient when it is difficult for large equipment to access for drilling;
• easiness of doing the work yourself. On light sandy soil it is easy to carry out drilling operations independently.

Furthermore, industrial, agricultural, and private facilities that use water for technical purposes can all benefit financially from this extraction technique.

Sand well – design features and device

All kinds of pits are drilled down to the aquifer’s level. But a sand well has specific characteristics. In contrast to other varieties, it requires a fine filter element.

It carries out the following duties:

• filters the injected water;
• catches silt and sand particles.

The components of a typical pit include the following:

• casing pipe. A neck is located in the upper part of the tubular column, located above the zero mark. It can accommodate a pumping station, as well as electrical and water communications;
• a surface pump or a submersible structure. The selection of pumping equipment is carried out individually. The choice of the optimal option depends on the depth of the horizon, as well as the required amount of pumped water;
• filter. It is made of corrosion-resistant steel. It is installed at the lower end of the casing and gradually immersed in the ground together with it until the water layer is reached. The size of the filtration is determined by the design of the element;
• feed pipeline. It is located inside the casing pipe and can be made of various materials. It is better to use plastic. It is lightweight, resistant to corrosion and capable of withstanding significant hydraulic loads.

One of the design characteristics is the filter’s ability to clean itself on its own when vibrations arise from the operation of the pump. However, the filter element can clog when storing a pit for the winter, as well as during seasonal variations in water levels and floods. These issues typically occur when the pumping station is malfunctioning.

Drilling sand wells – cost of work

Construction of self-sufficient water supply sources is handled by specialized companies employing specialized, high-performance machinery.

The following variables affect the overall cost of drilling sand wells:

• territorial location of the work site;
• features of the soil in the drilling zone;
• depth of the aquifers;
• degree of groundwater pollution;
• terrain at the work site;
• need for geodetic surveys;
• amount of transportation costs;
• costs for the purchase of pipes.

Drilling operations become more expensive when more work needs to be done to pump the extracted water to a transparent condition. The cost varies according to the area and quality of service. It ranges from 2,000 to 3,000 rubles per meter on average. You can always bargain with a contractor’s representative for a nice discount, given the overall amount of work involved.

Drilling on sand – what is the probability of the presence of an aquifer and siltation

Locating an aquiferous sand layer and drilling to the feeder horizon’s depth are the primary goals when drilling on sandy soils. An aquifer lens is what professional surveyors refer to as an underground water accumulation. Drilling operations don’t always result in the discovery of a pure underground river and a strong aquifer. Since there might not be any water in the drilled pit, it is frequently necessary to drill again.

The following circumstances could lead to a problematic situation involving the lack of water:

• when the depth of the shaft is below the level of the aquifer lens;
• with a deep level of underground rivers;
• in the absence of aquifer lenses at the work site.

It is also inappropriate to develop it because of the extremely low debit and accelerated siltation. It is preferable to create a new pit in this situation. With a pit depth of 20–30 m, it is difficult to say for sure whether water is present in a given area. The likelihood that adjacent aquifers will be found in a sand layer varies from 50 to 90% depending on the location.

Recall that finding an aquifer close by is not always fortunate. There is a good chance that the layer will silt up heavily if the soil is nearby.

Drilling into sand – important points

If you decide to handle the work yourself, consider the following:

• a manual auger can drill a pit about 30 m deep. If the aquifer is located at a great depth, powerful drilling equipment will be required;
• an auger is effective in homogeneous soil layers where there are no stony, granite or basalt rocks. A diamond tip will be required for strong layers;
• when water is located in a fine sand layer, there is a high probability of clogging the filter element. It is impossible to replace the filter at depth;
• the service life of a submersible pump does not exceed five years. It gradually deteriorates when abrasive particles get on the membranes and surfaces mating with the valve.

Check the reviews of nearby neighbors who have some operating experience and receive water from sand layers.

Doing the work yourself

During the drilling process, the steel drill’s shaft is torqued to smoothly deepen the hole. The blades of the auger rotate to raise the soil. The working element sinks farther into the earth, building up new sections as it does so.

Drill while paying attention to the proper order of action:

1. Prepare the necessary equipment for drilling, taking into account the depth of the location of the water layers.
2. Prepare the site where the drilling work will be carried out, clear it of debris and vegetation.
3. We went deep into the soil, forming a pit up to two meters deep for further placement of the caisson.
4. Install the manual drilling device on a tripod, securely fix it from possible displacement.
5. Hook a special rod with a drill bit to the cable and rotate it until it is completely immersed in the ground.
6. Secure the new segment simultaneously with the casing pipe and continue immersing it into the soil layers.

The working tool will reach the water layer once the auger has passed through the layer of impermeable clay. After cleaning it, you can put it to use.

Constructing a DIY sand well can be a satisfying project that adds value to your home and offers a dependable supply of water. You can guarantee the safety and functionality of your well by taking the proper precautions. You have been guided through all the crucial steps by this guide, which include choosing the ideal site, gathering the required supplies, and building the well.

As you begin this project, never forget to put safety first. Working with a friend, wearing safety gear, and being aware of local laws can all help to avoid mishaps and guarantee that your well is compliant with the law. To ensure a successful build, careful planning and preparation are essential.

Long-term use of your sand depends on proper maintenance. Maintaining your well’s structural integrity, checking for obstructions on a regular basis, and keeping an eye on the quality of the water will all help keep it in good operating order. You may have a consistent supply of clean water for many years to come if you continue to be proactive with upkeep.

In the end, building a DIY sand well is about more than just the product—it’salsoabout the process. It’s a chance to develop new abilities, use your hands, and feel proud of yourself. You can successfully finish this project and take pleasure in the advantages it offers for your house and garden if you have the appropriate attitude and approach.
