How this tool works
Use a timed bucket or meter measurement to calculate average flow.
Q = measured volume/timeExample calculation
The prefilled form is a worked example. Its base-unit inputs and expected outputs are shown below; use the reset button to restore it.

| Runtime | 60 |
Frequently asked questions
How should I choose the inputs?
Use measurements and local records for the stated period. All preset values are illustrative examples, not recommendations.
What does this result leave out?
Measure under actual operating pressure. This is not pipe-sizing advice; friction, pressure and simultaneous zones need separate design.

Costs & savingsCommon Water Waste Problems
Unexpected bills, damp areas, dripping fixtures and irrigation running after shutdown can signal unnecessary consumption. Start with an observation log including time and which equipment was operating. Avoid assuming every damp patch is a pipe leak; rainfall, drainage and other causes can produce similar symptoms. Investigate systematically before choosing a repair.

Garden irrigationCommon Irrigation Planning Mistakes
An area-based water volume is only the beginning. A working plan also needs outlet placement, operating pressure, flow, runtime and a watering window. Draw the route from source to each zone and note elevation changes. A calculator can produce a correct volume while the installation still fails to distribute it to the plants that require it.

Garden irrigationUnderstanding Irrigation Flow Rates
Flow rate tells you how quickly water moves, not whether plants need that amount or whether pressure is adequate. Keep litres per minute distinct from litres per hour. A zone total is the combined demand of the outlets operating together. Read product ratings at the stated operating pressure and do not assume every outlet reaches its label flow under every installation condition.

Water storageRainwater Tank Maintenance
List installed components, manufacturer instructions, inspection access and the person responsible for each task. Include the roof collection route, screens, tank, overflow, valves and delivery equipment. A maintenance plan should make a fault easy to identify and isolate. Follow product requirements rather than adopting an unsupported universal cleaning interval for every climate and use.
