The landscape of Silvassa is characterized by the Deccan Trap formations, consisting of multiple layers of volcanic basalt. Drilling in this terrain requires a specialized understanding of 'flow' geology, where hard, compact basalt often alternates with softer 'red bole' clay or vesicular basalt. In Silvassa, the most productive aquifers are typically found in the vesicular zones where gas bubbles once created natural storage spaces for groundwater. Our drilling rigs are equipped to handle these alternating strata, using casing pipes to seal off loose clay layers that could otherwise lead to 'caving' or jamming the drill string. We pay close attention to the inter-flow zones, as these are critical for high-yield borewells. In the dry summer months of Silvassa, the water table can fluctuate significantly, which is why we suggest drilling deeper to tap into the perennial secondary aquifers. Our engineering team provides custom pump selection based on the specific yield of the basaltic layers. Furthermore, we emphasize 'Hydro-fracturing' services for existing low-yield wells in the region to open up blocked water channels. This expertise ensures that your investment in a borewell provides maximum water discharge throughout the year.

A: For residential properties in Silvassa, the 6.5 inch dia drilling rate is ₹106 per feet. A typical 315 feet borewell here costs approximately ₹33,390 for drilling alone.
A: In Silvassa, the average water level is around 320 feet. However, to ensure a perennial supply, we recommend an ideal drilling depth of 315 feet.
A: Yes, "Additional Drilling" is a common service in Silvassa where we deepen existing wells to reach the current water table at 315 feet.
A: Yes, apartments in Silvassa usually require high-yield 6.5 or 7.5-inch wells drilled to 315 feet with high-HP pumps.
A: The Deccan Trap soil determines the bit type we use. Harder formations require tungsten carbide bits which we use as standard in Silvassa.
A: Groundwater in Silvassa is generally good, but since the terrain is Deccan Trap, we recommend a TDS test. We provide water testing services post-drilling to ensure safety.

Silvassa, the capital of Dadra and Nagar Haveli, is characterized by its unique Deccan Trap basaltic rock formations and undulating hilly terrain. For property owners in areas like Amli, Masat, and Rakholi, the geological structure demands specialized drilling techniques. Typically, the borewell depth required in this district ranges from 250 feet to over 600 feet to tap into sustainable fractured rock aquifers. In industrial zones such as Piparia and Sayli, the demand for water is higher, sometimes necessitating deeper exploration. The drilling method most commonly employed here is the "DTH" (Down-the-Hole) hammer technique, which is essential for penetrating the hard volcanic rock prevalent in the region. While the success rate is generally favorable, the primary challenge lies in the unpredictable nature of secondary porosity in basalt; missing a water-bearing fracture can result in a "dry hole." However, with professional hydrogeological surveys, the success rate remains robust. A well-cased borewell in Silvassa, using high-grade galvanized iron or heavy-duty PVC pipes, can easily last 20 to 30 years, providing a reliable yield throughout the seasons.
The groundwater in Silvassa and neighboring towns like Khanvel and Naroli is largely influenced by the basaltic mineralogy of the region. Most residents enjoy "Sweet Water" with moderate mineral content, though specific characteristics vary by locality:
Unlike coastal areas, the groundwater here is rarely salty or brackish. The main concern for residents is the "Hardness," which can cause scaling in water heaters and plumbing fixtures over time if not treated with water softeners.
Despite Silvassa being located near the Daman Ganga River and receiving substantial rainfall, water dependency on groundwater remains critical. The municipal corporation and PWD provide piped water supply to major residential blocks, but the rapid industrialization in Dadra and Nagar Haveli has put a strain on existing surface water resources. For the thriving industrial units and the sprawling residential complexes in Samarvarni and Kilvani, a borewell is not just a luxury but a necessity for operational continuity. During the pre-monsoon months, surface water levels in local reservoirs can fluctuate, leading to intermittent supply. Consequently, private borewells serve as the primary backup or main source for high-demand activities. Agricultural landholders in the hinterlands also depend heavily on borewells for irrigation to sustain crops beyond the rainy season, as the river-fed canal system does not reach every corner of the district.
The Union Territory administration has streamlined the procedure for groundwater extraction to prevent over-exploitation. Anyone planning to drill a borewell in Silvassa must follow the localized regulatory framework:
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.
