Tube Well Construction & Alluvial Water Systems in Trivandrum
Unlike deep rock borewells, tube wells are constructed in sedimentary, sandy, and alluvial formations common in coastal or river valley zones. Slotted strainer pipes enveloped in graded pea gravel act as natural filters, yielding large volumes of clean water without silt.

When to Choose a Tube Well in Kerala
Tube wells are particularly suitable in coastal and low-lying alluvial stretches of Thiruvananthapuram (Kazhakkoottam, Kaniyapuram, Attingal outskirts, and nearby coastal alluvial belts) where rock depth is deep or where sweet water lenses sit above bedrock in permeable sand beds.
By utilizing rotary excavation with mud circulation and inserting continuous-slot strainers, we ensure continuous water inflow without allowing sand or silt to damage pump impellers.
Precision Construction Process
- 1 Rotary Borehole Excavation: Drilling with bentonite slurry to stabilize sandy borehole walls against collapse.
- 2 Aquifer Profiling: Identifying high-permeability sand and gravel strata for optimal filter placement.
- 3 Slotted Screen Lowering: Positioning precision-engineered slotted PVC strainer pipes into the water-bearing zone.
- 4 Graded Gravel Packing: Enveloping the annular space with graded silica pea gravel to form a permanent natural filter.
- 5 Well Development & Jetting: Flushing until discharge water runs crystal clear and free of sediments.
Engineered Filter Materials
- • Slotted continuous-slot PVC and HDPE strainers resistant to corrosion
- • Graded silica pea gravel filter media tailored to local sand grain size
- • Submersible or surface centrifugal pumping setups
- • Watertight sanitary well cap seals
Transparent Cost Estimation
Tube well costs depend on borehole diameter, length of slotted screen pipe, depth of the sand aquifer, and volume of gravel packing needed.
