Water Tank Filling Time
from Bore Well to Terrace/Overhead Tank
Water Storage (Terrace / Overhead) Tank Filling Time is calculated here based on Tank Capacity with Lifting Height (Bore Depth) & Delivery Height (Building Height) & Discharge to calculate Tank Fill Time.

Tank Fill Time Strategy
What happens when reducing pipe size?
Match the delivery pipe size to the pump outlet whenever possible.
Example
If the pump has a 32 mm (1¼”) delivery outlet, continue with 32 mm pipe for most of the run. Reducing to 25 mm (1”) increases friction losses.
Parameter | 32 mm Pipe | 25 mm Pipe |
|---|---|---|
Flow rate | Higher | Lower |
Friction loss | Lower | Higher |
Pump efficiency | Better | Reduced |
Filling time | Faster | Slower |
Power consumption | Lower | Higher |
Pressure at tank | More stable | Reduced under flow |
When you reduce from 32 mm to 25 mm:
- Velocity increases
- Friction increases significantly
- Flow rate decreases
- Filling time increases
Users may not achieve the promised 10-minute target or whatever time line mentioned.
Practical Recommendation
Use:
- 32 mm (1¼”) HDPE or PVC delivery pipe from the pump to near the tank.
- Reduce to 25 mm (1”) only for the last short connection, if needed.
Avoid long runs of 25 mm pipe for a 50 LPM system.
Typical Friction Loss Comparison
For approximately 40 metres of pipe carrying 50 LPM:
- 32 mm pipe: around 3–5 metres head loss
- 25 mm pipe: around 10–15 metres head loss
That’s equivalent to adding another floor to the building.
