Proper borehole construction: what to know before the work begins

The borehole is not just a simple tube in the ground; it is an exact engineering structure, whose tightness and compatibility of the selected materials determine the safety of your water for the next two generations. Many landlords assume that it is enough to have a drilling machine in the yard, but in fact, the proper construction of boreholes is the only way to avoid contamination of the surface and clogging the system in just a few years' time. If a well is formed carelessly, even the thickest artesian layer can be irreversibly damaged.

We fully understand the concerns that arise in the face of complex bureaucracy, licences and fears of belonging to poor material. Nobody wants to discover that the new well pollutes drinking water or requires huge operating costs. In this article we will help you to become a knowledgeable customer who feels confident in your choice. Learn how a technically correct and durable water extraction system is being developed, which will provide clean artesian water for decades. We will look not only at the choice of materials, but also at the fundamental changes to the Land Council Act, which enters into force on 1 July 2026, and the necessary documentation to ensure that your home's water supply is stable and completely legal.

What is the proper construction of boreholes and why is it essential?

The borehole is not just a hole in the ground. It is a complex vertical engineering for the extraction of artesian water from deep, well protected underground layers. Often the myth is that the main thing is to reach a certain number of meters, but in reality the proper construction of boreholes is much more important than the depth itself. It is the design quality that determines whether your water will be clean and whether the system will serve the promised 50 years or more without any loss of capacity.

A well properly constructed serves as a safe shield. This prevents bacteria, surface sewage or agricultural chemicals from entering drinking water. Environmental responsibility also appears here; careless work can damage the entire water horizon, causing irreversible damage to the environment. We believe that every project is a personal promise to the client about a secure future, so quality is not discussed here.

Artesian water vs. groundwater: why choose a borehole?

When choosing how to extract water, it is important to understand the difference between water layers. The interlayer or artesian waters are situated under impermeable rocks, which provide natural filtration and constant chemical composition regardless of weather conditions. Shallow water wells whether the spits are directly dependent on precipitation and are exposed to a high risk of contamination. The borehole is a stable investment that will not fail even in the dryest summers.

Main risks when choosing the cheapest construction option

The lowest price in the market often means compromises at the expense of materials and technologies. If the proper construction of boreholes is ignored, the consequences can be expensive and difficult to repair:

• Invading well walls and sand clogging of the filter, which rapidly reduces water supply and damages the pump.
• Interlayer communication; if the cementation between pipes and rocks is formed in a superficial way, the dirty groundwater can freely enter the clean horizon.

Therefore, we always recommend choosing experienced masters because of the quality boreholes is the only way to bring peace of mind for decades.

Structural elements: Materials and sealing technologies

The proper construction of boreholes begins with a choice of materials that can withstand enormous pressure on the ground and at the same time ensure the purity of the water. We see that in 2026 double construction has become the standard of gold in the sector. It combines the steel outer casing, which bears the entire mechanical load, and the internal food grade uPVC tube, which protects water from corrosion products and metallic flavours.

The creation of a filter zone is no less important. Proper perforation and a precisely calculated gravel package or obssipka serves as the first level of protection against sand entering the system. In order to protect the well from surface water, dust or rodents, the essential element shall be the airtight head. It completely closes the top of the well, creating a safe barrier against any external pollution that would otherwise damage the entire expensive system.

Comparison of materials: steel vs. PVC

Steel tubes are indispensable when drilling works take place in loose or rocky ground at high depths because they are not deformed under pressure from the ground. Food class uPVC is the best solution for chemical neutrality in drinking water. This hybrid option ensures that: Alignment of LVGMC hole passport will run smoothly, as the design meets all modern hygiene requirements.

Cementing and insulation

The cementing of the doorway is a critical process that hermetically separates different water horizons from each other. Without it, there is a risk that the shallower, often contaminated groundwater will pass through the outside of the pipe into the deep artesian layer. Make sure that your chosen masters carry out this process carefully; it is a matter of peace of mind in the long term. If you plan your project, our team will be happy to explain what boreholes and material combinations will be most suitable for your plot of land geology.

Drill construction process in Latvia: from license to passport

Construction of the borehole starts long before the drilling machine arrives in your yard. The first step is a thorough hydrogeological survey in which we analyse data from neighboring wells and available geological maps. This allows us to predict the required depth and specifics of the water horizon, protecting you from unforeseen expenses. The proper construction of the boreholes cannot be imagined without this preparatory phase, because each country in Latvia hides its challenges.

Since 1 July 2026, the entry into force of the latest amendments to the Land Council Act, the alignment of documentation has become a critical stage. If the planned well is deeper than 20 metres or the intended water abstraction exceeds 10 m3 a day, the State Environmental Service (VVD) licence is required. Currently, the state fee for such a license is EUR 35.57. It is only after all authorisations have been granted and coordination with the municipality that the drilling works themselves can be started by selecting the most appropriate rotation or impact drilling technology for geology.

After drilling is followed by no less important stage: well rinse and pumping until completely clear water is obtained. This process can take hours or even days, but it is the only way to make sure that the system works smoothly and the filter has not clogged.

What is a borehole passport and why should it be protected?

The drilling passport is your most expensive document after the home book. It records unique technical data: static and dynamic water level, debit or water supply speed and structural section. Legally impossible without a passport borehole operation. In addition, these data are critical to the choice of the correct pump; if the pump is installed at the wrong depth, it can quickly exit the range. Note that preparation of a well passport at the Latvian Environmental, Geological and Meteorological Centre (LVGMC) currently costs EUR 337.32 without VAT.

Site selection and technical access

When planning a well site, we always remind of sanitary protection zones. The law sets strict distances from possible sources of pollution, such as septics, barns or neighbouring land borders. It is also to be considered that drilling requires heavy machinery. Large cars need a stable driveway and a large enough work area to allow the masters to safely maneuver and perform their work.

Drill integration and maintenance in home systems

The borehole is only the beginning of the journey towards an independent water supply. To get the water to your tap or heating system, precise choice of pump based on a well passport is required. We analyse data on static and dynamic levels to determine optimal pump power and immersion depth. Too powerful a pump may cause unnecessary turbulence and contribute to the flow of sand, while a weak pump will not provide the necessary pressure on the upper floors of the building.

A mandatory step before drinking water is to perform a full chemical and bacteriological analysis in an accredited laboratory. Only in this way can you be sure that the artesian water is completely clean. Also, do not forget about preventive maintenance; although the proper design of the boreholes ensures the longevity of the system, it is recommended to check the equipment every few years and, if necessary, rinse to maintain a constant high water debit.

Heat pumps and boreholes: energy efficient tandem

The proper construction of boreholes is critical if you plan to entrust home heating to modern technologies. Stable water levels and sufficient capacity are key to: Air-to-water heat pumps whether the cooling function of ground heat pumps works effectively. Water quality has a direct impact on the longevity of heat exchangers; too much calcareous water can cause deposits that reduce system efficiency over time. Read more about this in our article: Air-water heat pump: Full guide for efficient heating in Latvia in 2026.

The need for water treatment

The geological conditions of Latvia dictate their rules, and increased iron, lime and manganese content is often found in artesian water. Although these elements are not dangerous to health, they can leave a trace of plumbing and shorten the life of washing machines or boilers. The good news is that professionally designed construction and high-quality sealing protect the well from surface contamination, making the necessary filtration systems simpler and cheaper to maintain them. We are always ready to help you find the best solution for your home to always have clear and tasty water.

Frequently asked questions about the installation of boreholes

Is a construction permit necessary for the installation of a borehole?

Yes, if the planned well is deeper than 20 metres or the water abstraction exceeds 10 cubic metres per day, a licence issued by the State Environmental Service is required. Although it is often referred to as a building permit, it is officially a license for the use of earth's depths. Before starting work, the project must also be coordinated with the local government to verify compliance with sanitary standards and protective zones in your property.

How deep should a borehole be in Latvia?

The depth of the well depends directly on the geological cut of your location and the quality of the desired water layer. In Latvia, the boreholes of private houses usually range from 20 to 120 meters. For example, 40 to 60 metres are often enough to reach a high-quality artesian horizon. We always perform a preliminary analysis of neighbouring well data to predict the exact depth required for a stable water supply on your farm.

Why can it become cloudy in the water well after heavy rains?

Water opacity after rain usually indicates that proper construction of boreholes The system has not been fully followed or the sealing system has been damaged. This means that surface sewage enters drinking water through the outside of the pipe or through a non-blistered main. This situation is dangerous because bacteria and nitrates can enter the system along with the mud. In such cases immediate expert inspection and additional insulation of the top of the well are required.

How long is a fully equipped borehole built?

The drilling works usually take between two and five working days, depending on the hardness of the ground and the number of meters planned. However, the complete process, including the installation of the pump, the automatic connection and the introduction of pipelines into the house, takes approximately one working week in total. It should be noted that document reconciliation before starting work requires additional time, so planning should start at least one month before the desired construction process begins.

What is the difference between black metal and galvanized pipes in a hole?

Black steel tubes are a classic choice due to their high mechanical strength, but they are subject to corrosion over time. Zinc coating can have a negative effect on the chemical composition of water and human health. The best alternative is a steel casing with an internal food class uPVC column, which combines metal durability with plastic hygiene and longevity.
