Groundwater Geology: Silvassa

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.
