Borewell construction in the coastal district of Diu requires specialized technical expertise due to the sensitive balance between freshwater and saltwater. The geological profile typically consists of marine sediments, fine sand, and clay lenses. The primary risk in Diu is 'Saltwater Intrusion,' where drilling too deep or pumping too aggressively can pull brackish water into the freshwater zone. To combat this, we implement 'Telescopic Casing' designs, where a larger diameter outer pipe seals off the shallow saline layers, allowing us to safely tap into the deeper, sweet-water aquifers. We often use Electrical Resistivity Tomography (ERT) in Diu to map the salinity profile before we begin drilling. Our pumps and casing materials are chosen for their corrosion resistance, as the saline coastal air and soil can be highly reactive. We also specialize in 'Cement Grouting' techniques to create an impermeable seal between different water layers, ensuring the long-term purity of your water supply. For residents and businesses in Diu, we provide integrated solutions that include advanced filtration if the water contains high total dissolved solids (TDS). This ensures a sustainable, high-quality water solution even in the challenging marine environment of the coast.

A: For residential properties in Diu, the 6.5 inch dia drilling rate is ₹102 per feet. A typical 405 feet borewell here costs approximately ₹41,310 for drilling alone.
A: In Diu, the average water level is around 310 feet. However, to ensure a perennial supply, we recommend an ideal drilling depth of 405 feet.
A: The Coastal soil determines the bit type we use. Harder formations require tungsten carbide bits which we use as standard in Diu.
A: For a standard 405 feet borewell in Diu, the drilling process usually takes 12 to 18 hours, depending on the hardness of the Coastal strata.
A: Yes, "Additional Drilling" is a common service in Diu where we deepen existing wells to reach the current water table at 405 feet.
A: For 405 feet in Diu, a 1.5 HP to 3 HP submersible pump is usually required depending on the required water discharge.

Diu, a small island district located off the coast of Gujarat and part of the Union Territory of Dadra and Nagar Haveli and Daman and Diu, faces a unique water dependency landscape. Surrounded by the Arabian Sea, the district has limited freshwater sources, with an average annual rainfall of approximately 598.6 mm. Local water resources include the Chasi River and several seasonal ponds that help in recharging the groundwater, though the total storage is relatively small at 1.8 MCM. Currently, Diu relies heavily on treated water supplied through the Sardar Sarovar project, which provides about 9 MLD through local treatment plants. Despite these surface supplies, the residential hubs in Diu town and the suburbs like Bucharwada and Ghoghla face significant water dependency, especially during the peak tourist seasons when demand spikes.
The possibility of water shortage is a persistent concern in Diu, as groundwater serves as a critical secondary source for domestic and livestock needs. The district has been categorized as "Over-exploited" in recent groundwater assessments, meaning the rate of extraction exceeds the natural recharge. For many independent houses and the hospitality sector in the Diu district headquarters, a borewell is often required to bridge the gap in supply during the dry months. However, the availability of fresh groundwater is restricted to a thin lens floating over denser seawater, making sustainable extraction a delicate balance for the local community.
Given the "Over-exploited" status of groundwater in Diu, the administration maintains strict control over the drilling of new borewells to prevent saltwater intrusion into the freshwater aquifers. The approval procedure is governed by the Public Works Department (PWD) and the local municipal or panchayat authorities. Every citizen or commercial entity in the Diu district headquarters or rural areas like Saudawada must seek a formal No Objection Certificate (NOC) before commencing any drilling activity. The process typically starts at the Public Works Department located on Fort Road, where applicants submit land ownership documents, house tax receipts, and an identity proof.
A specific localized requirement in Diu is the technical vetting of the proposed borewell depth and location by the PWD to ensure it does not adversely affect the coastal water table. During years of severe water stress, the District Collector may impose a total ban on new private drilling to protect the existing community drinking water schemes. Once the preliminary NOC is obtained, the drilling must be executed by registered contractors, and the well must be registered with the department within a stipulated timeframe. The local administration also emphasizes the mandatory installation of rainwater harvesting systems for all new borewell owners to facilitate the recharge of the fragile coastal lens, ensuring long-term resource sustainability.
The quality of water in Diu is heavily influenced by its maritime geography and the proximity of the Arabian Sea. Residents and businesses across the island encounter varying water characteristics based on their distance from the coast:
Borewell drilling in Diu is a technically challenging endeavor due to the island's coastal geography and the risk of saltwater contamination. In the Diu headquarters and surrounding coastal plains, the required depth for a borewell is generally shallow, ranging between 60 feet and 120 feet, as drilling deeper often risks hitting saline aquifers. The primary method used by local contractors is "Mini Borewell" or "Jet Drilling," which is effective in the sandy and soft limestone layers typical of the island. The success rate is moderate, often limited by the quality of the water strike rather than the presence of water itself, as salinity remains the biggest hurdle for new installations.
The cost involved in a Diu borewell project includes the per-foot drilling rate—which ranges from ₹90 to ₹120 for standard services—plus the cost of high-grade PVC casing pipes essential for preventing sand collapse in the upper strata. A typical shallow borewell setup can cost between ₹35,000 and ₹60,000 depending on site accessibility and the type of submersible pump used. The typical life of a borewell in this region is relatively short, often 10 to 12 years, as corrosion from the salty environment and the risk of saline ingress can render the well unusable. To maximize longevity, local experts recommend scientific site selection and avoid over-pumping, which can pull seawater into the freshwater zone, a common challenge in the Diu district.
Find the borewell cost for your land based on the state, city, and locality. The cost estimate for a borewell tends to vary from area to area. For example, the borewell cost in a village is not the same as the cost in a city. It also depends on factors such as the accessibility of the borewell point, the type of soil (rock or loose soil), labor rates in the locality, PVC pipe and lid prices, and the availability of borewell equipment nearby.
