Tube Well Construction

Sri Lanka's Trusted Tube Well Experts

Vishwalanka's Water Engineering Division has been drilling tube wells across Sri Lanka since 2009. With 180+ successful projects in all terrains — from hard rock in the Central Province to alluvial soil in the North — we have the experience, equipment, and expertise to find and deliver clean groundwater for your home, farm, or business.

We use state-of-the-art rotary drilling rigs imported from Germany and Japan, capable of drilling up to 400 feet in any geological formation. Every project includes a post-drilling water quality test and pump commissioning.

Our Tube Well Process

1. Free Site Assessment — Our hydrogeologist visits your property and evaluates the site for drilling suitability.
2. Water Survey (Optional) — Geophysical resistivity survey to pinpoint the exact drilling location and estimate water depth/yield.
3. Mobilization — Drilling rig and crew mobilized to your site, usually within 2–5 working days of quotation approval.
4. Drilling — We drill to the agreed depth using rotary/percussion methods, monitoring geological formations continuously.
5. Casing & Gravel Pack — PVC/steel casing installed with gravel packing to prevent sand entry and maximise water yield.
6. Well Development — The well is developed by pumping to remove drilling fluid and fine particles, maximising yield.
7. Water Testing — Water samples collected and tested at an approved laboratory for quality certification.
8. Pump Installation — Submersible pump selected, installed, and commissioned. Final inspection and handover.
