Complete service for the construction of wells
Sarda Trivelsonda Group offers a full service dedicated to the design and construction of water wells in Olbia, intended for private, agricultural, industrial and public contexts.
The activities are carried out in full compliance with current regulations and with up-to-date techniques, which allow for precise operation even in complex geological conditions.
The company manages internally the documentation necessary for starting the works: a fundamental support that allows the customer to receive a simple, clear service without bureaucratic procedures superfluous.
Types of wells built
Artesian wells are designed to tap a pressurized aquifer. Once the aquifer is reached, natural buoyancy can allow the water to rise spontaneously to the piezometric level. Sarda Trivelsonda Group performs this type of drilling through vertical excavations with millimeter precision, using technologies that ensure a clean and stable hole. This solution is ideal for continuous use and for terrain with deep aquifers.
Ordinary wells
Ordinary wells, also known as phreatic or filter wells, allow access to non-pressurized aquifers. The water does not rise spontaneously above ground level, but can be extracted using suitable pumps. This type is commonly used for irrigation, non-potable domestic use, and agricultural purposes. The terrain is studied in advance to determine the depth, drilling diameter, and choice of materials.
Competence and professionalism
Drilling techniques used
For the realization of water wells in Olbia and in the rest of Sardinia, Sarda Trivelsonda Group uses modern, high-performance drilling techniques, designed to ensure precision, safety, and full plant efficiency. The primary methodology used is drilling rotary percussion, an ideal solution for tackling the island's typical terrain, often characterised by compact rocks and complex stratifications.
In this process, the digging action is carried out by a down-the-hole hammer, powered by a compressed air system. The tool progressively crushes the rock, while the resulting debris is immediately expelled thanks to the upward flow of air that rises along the hole. This system keeps the bottom perfectly clean throughout all drilling phases, ensuring greater precision and reducing drilling times.
modalità operative
Compressed air can be introduced into the bottom of the hole through the rods in two operating modes:
Dry drilling:
Debris is rapidly lifted by the high-energy air, allowing for effective removal of the crushed material.
Foam drilling:
The combined action of air and foam further facilitates debris removal. The foam keeps the hole stable and leaves the bottom perfectly clean, making this technique particularly useful in more unstable or fine-grained soil.
Depending on the geological conditions and the characteristics required by the project, down-the-hole hammer cutters of different diameters are used, selected to obtain the best performance in both deep and medium-depth drilling.
Types of well lining and materials used
Cladding is an essential step to ensure the durability and safety of the structure. Sarda Trivelsonda Group uses pipes in Non-toxic and certified PVC, suitable for contact with fluids also intended for food use, as required by the ministerial decree.
The pipes, available in various diameters, are selected based on the cutting edge used during drilling and the type of aquifer tapped. Thanks to the quality of the materials used, the well maintains stability, cleanliness, and proper water flow over time.
