Why Proper Tubewell Installation Matters
Installing a deep tubewell requires technical precision, accurate boring depth, proper pipe selection, and correct pump fitting. A poorly-installed tubewell can cause:
- Low water pressure
- Sand contamination
- Air-lock problems
- Pump overheating
- Frequent repairs
Deep tubewell installation involves understanding soil composition, aquifer level, water table depth, pipe diameter, and hydrogeological safety standards.

Step-by-Step Deep Tubewell Installation Process
Below is the most accurate and professional technical installation process used in Bangladesh.
Step 1:-Site Survey & Water Table Assessment
Before drilling, an expert inspects the area to determine:
- Soil structure
- Aquifer depth
- Arsenic risk zone
- Groundwater pressure
- Space for machine setup
You can verify safe zones from the Department of Public Health Engineering (DPHE) website.
Step 2:-Marking the Drilling Point (Bore Point Selection)
The exact drilling point is selected based on:
- Distance from septic tanks
- Electrical line clearance
- Water flow requirement
- Soil hardness
- Pump installation convenience
A wrong bore point may lead to low-yield aquifers.
Step 3:-Borehole Drilling (Boring Operation)
The drilling machine creates a borehole gradually through multiple soil layers:
Soil Layers Typically Encountered
- Topsoil
- Soft clay
- Hard clay
- Sand
- Gravel
- Deep aquifer layer
The depth varies by region (typically 250–650 ft for most areas). Drilling continues until a stable, high-yield aquifer is reached.
For recommended depth ranges, see our Deep Tubewell Depth Guide.
Step 4:-Casing Pipe Installation
Casing pipes are inserted inside the borehole to prevent:
- Soil collapse
- Water contamination
- Sand entry
Best Pipe Sizes for Deep Tubewell
- 2-inch → household use
- 3-inch → commercial setups
- 4-inch → high-demand operations
PVC or GI casing pipes are typically used depending on soil hardness.
Step 5:-Screen Filter Installation (The Key Step)
A Stainless Steel (SS) Screen Filter is installed at the water-bearing layer.
Benefits of SS Screen:
- Prevents sand entry
- Improves water clarity
- Long-lasting & corrosion-proof
- Maintains stable water pressure
Screen positioning determines tubewell lifetime.
Step 6:-Gravel Packing (Filtering Layer Setup)
Gravel is added around the casing pipe to:
- Filter fine particles
- Strengthen the well structure
- Increase water flow
This step is crucial for long-term tubewell efficiency.
Step 7:-Final Development of the Well (Air Blowing / Pumping)
After casing and gravel placement, the well is developed by:
- Air compressor flushing
- High-pressure pumping
- Removing muddy water
- Stabilizing groundwater flow
This process clears sediments and enhances water quality.
Step 8:-Pump Installation (Motor Setup)
Pump selection depends on depth, pipe size, and water requirement:
Common Pump Types
- Submersible Pump
- Jet Pump
- Centrifugal Pump
- 1 HP / 1.5 HP / 2 HP motors
Deeper wells usually require submersible pumps for stable pressure.
Step 9:-Water Quality Testing
After installation, water is tested for:
- TDS
- Iron level
- pH value
- Arsenic
- Turbidity
For detailed water safety standards, see WHO Water Quality Guidelines.
Step 10:-Final Inspection & Handover
The final phase includes:
- Checking pump pressure
- Ensuring no pipe leakage
- Evaluating flow rate (LPM)
- Running a 10–20 minute test
- Providing maintenance guidelines
This ensures long-term performance of the tubewell.
How Long Does Deep Tubewell Installation Take?
- Household setup: 4–8 hours
- Commercial: 8–12 hours
- Industrial: 1–2 days
(Depending on soil hardness and depth)
Common Problems During Tubewell Installation
- Hard rock layers → delays drilling
- Sandy layers → require extra casing
- Narrow space for drilling machine
- Water table fluctuation
- Old declining wells nearby
Maintenance Tips After Installation
- Run pump regularly to stabilize water flow
- Clean pump every 3–6 months
- Test water quality annually
- Repair leakage immediately
- Avoid over-pumping the water source
