Borewell Drilling & Bore Hole Construction in Trivandrum
Akash Water Solutions undertakes deep-rock borewell drilling across Thiruvananthapuram, utilizing modern truck-mounted hydraulic rotary rigs with down-the-hole (DTH) pneumatic button bits capable of penetrating hard crystalline granite bedrock to access prolific water-bearing fracture zones.

Trivandrum Geological Strata & Drilling Approach
In Thiruvananthapuram, overburden soil thickness ranges from 20–40 feet in elevated inland terrains (Nedumangad, Vembayam, Kanyakulangara, Peroorkada) to 80–120+ feet in coastal or alluvial belts (Kazhakkoottam, Kaniyapuram, Chanthavila). Rig configuration and bit diameters (6" or 6.5") are selected specifically to match local strata.
Our drilling methodology prevents borehole collapse by seating heavy-duty PVC casing pipes firmly into the top of the solid granite rock bed before hammering deep into the aquifer fracture zones.
Step-by-Step Construction Process
- 1 Site Inspection & Rig Clearance: Verifying 9–10 feet road and gate width for truck-mounted hydraulic drilling rigs.
- 2 Overburden Soil Drilling: Drilling through loose topsoil, laterite, and clay down to firm crystalline bedrock collar.
- 3 Casing Pipe Seating: Inserting heavy ISI-grade threaded PVC casing pipes to seal out contaminated surface runoff.
- 4 DTH Rock Drilling: High-pressure pneumatic hammer button-bit drilling into deep water-bearing rock fractures.
- 5 Compressor Flushing: High-pressure air flushing to clear rock dust, verify continuous yield, and check clear discharge.
Certified Materials & Rig Machinery
- • High-grade ISI marked heavy PVC borewell casing pipes (Finolex / certified standards)
- • Tungsten carbide button bits (4.5" to 6.5" diameter) for hard granite penetration
- • High-pressure mobile air compressors for yield development and cleaning
- • Submersible multistage stainless steel pump sets with safety suspension cables
- • Heavy-duty HDPE column pressure pipes with brass and SS adapters
Transparent Estimating Advice
Avoid relying solely on advertised per-foot rates over the phone. Total construction cost depends heavily on overburden depth, casing pipe footage, rock hardness, and pump selection.
