Groundwater Geology: Siwan

In the fertile plains of Siwan, the geology consists of deep, unconsolidated alluvial deposits including sand, silt, clay, and gravel. Unlike rocky terrains, the challenge in Siwan is not the hardness of the ground, but the stability of the borehole. We utilize Direct Rotary or Reverse Rotary drilling technologies to manage these soft strata effectively. A crucial part of our service in Siwan is the design of the assembly, where we strategically place 'V-Wire' screens or slotted pipes against the most productive sand aquifers. To prevent the 'sand-pumping' issue common in this region, we perform precision gravel packing, filling the annular space with graded pebbles to act as a natural filter. This ensures crystal-clear water and protects your submersible pump from premature wear and tear. Because Siwan may have multiple aquifer layers, we help clients identify the second or third layer to avoid the risk of surface pollutants or agricultural runoff. Our development process includes high-velocity surging and air-compressor cleaning to stabilize the aquifer and maximize flow. This professional approach results in a high-discharge tube well capable of supporting large-scale irrigation or high-capacity residential requirements.
