In the fertile plains of Kajalgaon, the geology consists of deep, unconsolidated alluvial deposits including sand, silt, clay, and gravel. Unlike rocky terrains, the challenge in Kajalgaon 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 Kajalgaon 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 Kajalgaon 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.
Technical Setup for Alluvial Terrain:
Direct Rotary (DR) Rig with Gravel Packing for Sand Aquifers.
*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 Kajalgaon, the 6.5 inch dia drilling rate is ₹103 per feet. A typical 355 feet borewell here costs approximately ₹36,565 for drilling alone.
A: In Kajalgaon, the average water level is around 295 feet. However, to ensure a perennial supply, we recommend an ideal drilling depth of 355 feet.
A: Summer months (March to June) are best in Kajalgaon because the water table is at its lowest, ensuring your well never goes dry in the future.
A: We provide a warranty on the materials (pipes/pumps) and guarantee the drilling depth as per the ₹103/ft agreement in Kajalgaon.
A: Groundwater in Kajalgaon is generally good, but since the terrain is Alluvial, we recommend a TDS test. We provide water testing services post-drilling to ensure safety.
A: The Alluvial soil determines the bit type we use. Harder formations require tungsten carbide bits which we use as standard in Kajalgaon.

Kajalgaon, the administrative headquarters of the Chirang district in BTR (Bodoland Territorial Region), is situated in the foothills of the Bhutan Himalayas within the Bhabar-Terai belt. The geology here is primarily composed of unconsolidated sediments including boulders, pebbles, gravel, and coarse sand mixed with clay. Drilling a borewell in Kajalgaon is a technical challenge due to the "boulder zone" prevalent in this region. Standard rotary rigs often struggle with the heavy stone layers, necessitating the use of specialized ODEX (Overburden Drilling Excentric) or high-capacity DTH rigs with casing advancement systems. The approximate depth required for a successful domestic borewell is relatively shallow, often ranging between 120 to 250 feet, as the water table in this northern Assam belt is high. However, the cost is higher than in the southern plains due to the difficulty of penetrating the stony layers and the essential requirement for heavy-duty iron or high-grade PVC casing to prevent the bore from collapsing in the loose gravel.
The water quality in Kajalgaon and nearby areas like Basugaon and Bijni is generally fresh, owing to the high annual rainfall and recharge from the mountain streams. However, specific mineral characteristics are common in this belt:
Kajalgaon is a rapidly developing administrative hub, yet its public water infrastructure is still catching up with its growing population. While the Public Health Engineering (PHE) department operates several water supply schemes, the consistency and pressure are often inadequate for modern residential needs. The district’s high dependency on agriculture and the seasonal nature of the local rivulets make groundwater the primary lifeline. In the main town area, a private borewell is considered a basic necessity for every household and government quarter to ensure a 24/7 supply. The risk of water shortage is low in terms of quantity, but "quality shortage" exists due to the iron contamination in shallow aquifers. This drives residents to drill deeper to reach the second or third aquifer layer, where the water is often cleaner and more reliable throughout the year.
In Kajalgaon and throughout the Chirang district, groundwater extraction is monitored to ensure the sustainability of the Terai aquifers. The localized approval and drilling process involves:
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.
