How the Borewell Water Yield Calculator works

The Borewell Water Yield Calculator uses Container volume, Time to fill it, Pumping hours per day, and People to supply to calculate Borewell yield, Daily output, People it can supply, Time to fill a 1000 L tank, and Surplus for your family. Its engine applies Flow (litres/second) = container volume ÷ fill time; the worked values below come from that same live calculation rather than a separately typed example.

With Container volume 20 litres, Time to fill it 12 seconds, Pumping hours per day 4 h, and People to supply 4, the main worked-example result is Borewell yield = 6,000 litres/hour.

Formula, derivation and worked example

The simplest field test for a borewell: run the pump, time how long a known container takes to fill and convert to litres per hour. Do the test after the pump has run for 15 minutes so the level has settled — that gives the sustainable yield rather than the initial surge.

Flow (litres/second) = container volume ÷ fill time

Yield (litres/hour) = flow × 3600

Daily output = yield × pumping hours

Substitution steps

1. Flow
volume ÷ time
= 1.667 L/s
2. Yield
flow × 3600
= 6,000 L/h
3. Daily
yield × pumping hours
= 24,000 L/day

Computed example results

Borewell yield: 6,000 litres/hour; 1.67 litres per second
Daily output: 24,000 litres/day
People it can supply: 178 persons; at 135 litres per person per day
Time to fill a 1000 L tank: 10 minutes
Surplus for your family: 23,460 litres/day

Understanding the result

Read the main result together with supporting checks, assumptions, limits and intermediate values.

For a manual check, repeat the first equation, confirm the units and change one input at a time.

Assumptions and calculation scope

Container volume is assumed to be entered in litres; converting from another unit before entry avoids changing the numerical meaning of the calculation.
Borewell Water Yield Calculator applies the displayed Flow (litres/second) = container volume ÷ fill time relationship to the entered construction inputs. Factors that are not exposed as inputs or stated assumptions are outside this calculator's calculation scope.

Common mistakes when using Borewell Water Yield Calculator

Do not mix units for Container volume (litres), Time to fill it (seconds), Pumping hours per day (h). A unit mismatch changes the input magnitude even when the typed number looks reasonable.
Do not replace the displayed Flow (litres/second) = container volume ÷ fill time relationship with a different convention without also changing the underlying assumptions; compare like-for-like methods when checking the result.
Do not treat Borewell yield = 6,000 litres/hour from the worked example as a universal answer. It belongs to the displayed example inputs and must be recalculated for the actual case.

When the Borewell Water Yield Calculator is useful

Borewell Water Yield Calculator is designed for cases where Container volume, Time to fill it, Pumping hours per day, People to supply are known and you need Borewell yield, Daily output, People it can supply. The page keeps the live calculator, calculation method and worked example together so the result can be checked instead of treated as a black-box number.

Use the calculator for the scope described by its inputs and notes. The displayed method is Flow (litres/second) = container volume ÷ fill time. If the real project or decision needs factors that are not represented here, treat the result as an estimate and add the missing checks separately.

Container volume and Time to fill it: what changes the answer

The worked example uses Container volume = 20 litres, Time to fill it = 12 seconds, Pumping hours per day = 4 h, People to supply = 4. With those values, Borewell yield is 6,000 litres/hour. Changing an input should be interpreted according to that field's unit, range, option and hint rather than by the number alone.

For this calculator, the main input roles are: Container volume (litres): Measured or known container volume used by the calculation engine. Time to fill it (seconds): Measured or known time to fill it used by the calculation engine. Pumping hours per day (h): Measured or known pumping hours per day used by the calculation engine. People to supply: Measured or known people to supply used by the calculation engine.

How to sanity-check a Borewell Water Yield Calculator result

Start by confirming the entered values and units, then compare the substituted working with the displayed formula or calculation steps. Pay particular attention to Borewell yield, because it is the first worked-example output shown by the live engine.

Finally, compare the result with the assumptions, warnings and related calculators on this page. A nearby calculator can be useful as a cross-check when it measures the same workflow from a different input or output direction.

Yield (litres/hour) = flow × 3600
Daily output = yield × pumping hours

Worked example

1A 20 litre bucket fills in 12 seconds → 1.67 litres/second.
2Yield = 1.67 × 3600 = 6,000 litres per hour.
3Running 4 hours a day gives 24,000 litres — enough for about 44 people.

Tips

Repeat the test in summer; yields drop sharply when the water table falls.
Do not run the pump dry — install a dry-run protector to save the motor.

Frequently asked questions

What is a good borewell yield?

Anything above 2,000 litres per hour comfortably supplies a household. Below 500 lph the bore is considered weak.

How do I measure without a flow meter?

The bucket test used here is the standard field method and is accurate within about 5%.

Does yield change over the year?

Yes. Yields are highest after the monsoon and lowest in late summer, sometimes by half.

What inputs does the Borewell Water Yield Calculator use?

It uses Container volume, Time to fill it, Pumping hours per day, and People to supply. Follow the unit printed for each field and choose any selectable option to match the real scenario.

What does the Borewell Water Yield Calculator calculate?

It calculates Borewell yield, Daily output, People it can supply, Time to fill a 1000 L tank, and Surplus for your family. With the displayed default inputs, Borewell yield is 6,000 litres/hour.

Which formula does the Borewell Water Yield Calculator use?

The primary relationship is Flow (litres/second) = container volume ÷ fill time. The page also shows substituted values and calculation steps so the result can be checked independently.
