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.

*Regulations updated as per 2026 state-wise groundwater policies. Non-compliance may lead to sealing of the borewell and environmental fines.
A: For residential properties in Siwan, the 6.5 inch dia drilling rate is ₹110 per feet. A typical 290 feet borewell here costs approximately ₹31,900 for drilling alone.
A: In Siwan, the average water level is around 290 feet. However, to ensure a perennial supply, we recommend an ideal drilling depth of 290 feet.
A: Yes, under the Bihar Ground Water Act, registration is mandatory. In Siwan, we assist clients in obtaining the necessary NOC (No Objection Certificate) before drilling starts.
A: PVC casing pipes in Siwan vary by brand. For Alluvial terrain, we use Class-4 or Class-5 pipes to withstand underground pressure.
A: In Siwan, while we use scientific methods, groundwater is nature-dependent. We only charge for the drilling depth at ₹110/ft regardless of the yield.
A: Flushing involves cleaning the borewell with high air pressure. In Siwan, we recommend flushing every 3 years to maintain the yield from the Alluvial aquifers.
This Borewell Cost is also applicable to Siwan, Maharajganj, Mairwa, Darauli, Guthani, Raghunathpur, Siswan, Barharia, Pachrukhi, Hussainganj, Zeeradei, Andar, Daraunda, Bhagwanpur Hat, Basantpur, Lakri Nabiganj, Goreyakothi, Nautan, Hasanpura, Tarwara.
In the fertile Gangetic plains of Siwan, the subsurface is predominantly composed of thick layers of alluvium, fine sand, and silt. For residents in Siwan town, Mairwa, and Maharajganj, the borewell depth typically ranges from 300 to 450 feet to secure a perennial water supply. Due to the loose soil structure, the Direct Rotary (DR) drilling method is the most effective and widely used approach in this region. The cost involved is largely dictated by the extensive use of high-quality PVC casing pipes (Class-4 or Class-5) required to prevent the borehole from collapsing in sandy strata. While the borewell success rate is generally high across the district, a major difficulty is navigating the "running sand" layers which can clog the assembly if not properly gravel-packed. A professionally installed borewell in areas like Mahadeva or Gandhi Maidan can have a life of over 20 years, provided the screen filters are maintained to prevent siltation.
The groundwater in Siwan is primarily Sweet and Potable, but it faces significant localized quality challenges. A major concern in parts of the district, particularly near the Daha River and blocks like Barharia, is the elevated level of Arsenic and Iron. High iron content often gives the water a distinct Metallic Taste and causes reddish staining on household fixtures. Furthermore, urban centers like Naya Bazar and Babunia Road often report Hard Water, characterized by high calcium levels that lead to scaling in plumbing systems. While Salty or Brackish water is not a common issue in this inland region, the Total Dissolved Solids (TDS) can fluctuate during the summer months. For safe consumption, many households in Siwan Headquarters utilize RO (Reverse Osmosis) and iron-removal filters to manage these mineral levels and ensure the water is soft and clear.
Siwan has a high water dependency on its underground aquifers, as surface water sources like the Daha and Ghaghara Rivers are often plagued by pollution or seasonal flow reductions. While the local municipality provides a piped water supply, it often struggles to meet the peak demands of a growing population in neighborhoods like Shanti Nagar and Ramaiypatti. This leads to a persistent water shortage possibility during the intense heatwaves of April and May. Consequently, a private borewell is highly required for residents to ensure a consistent 24/7 supply for drinking, sanitation, and cooling. In the absence of large-scale perennial canal irrigation in many tehsils, deep tube wells also remain the primary lifeline for the agricultural sector in the outskirts of the district, making them an indispensable asset for the local community.
The borewell approval procedure in Siwan is managed under the Bihar Ground Water (Management and Control) Act. Property owners intending to sink a new well must register with the Minor Water Resources Department (MWRD). The application process typically requires submitting land ownership documents (Jamabandi/Khatiyan) and a site map to the Siwan Municipal Council or the local Block Development Office (BDO). For residential boring, the focus is on maintaining a safe distance from septic tanks and ensuring the extraction does not interfere with public water sources. In commercial cases, a formal No Objection Certificate (NOC) is mandatory to ensure environmental compliance. It is highly recommended to work with a registered driller who is familiar with the Siwan District Collectorate regulations to avoid legal penalties and to ensure that mandatory rainwater harvesting measures are integrated into the design.
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.
