Farm pond rainwater-harvesting capacity calculator.
Estimate pond storage and days of crop demand from pond geometry.
Farm pond rainwater-harvesting capacity inputs
Planning calculation only. Confirm water source, pump curve, elevation, filters, pipe material, emitter uniformity, solar resource, electrical protection and local water rules with a qualified irrigation professional.
Method: The calculator applies entered dimensions, flows and efficiencies as a transparent farm-planning estimate.
Inputs used: Pond top area = 1,000 m²; Pond bottom area = 400 m²; Water depth = 3 m; Crop irrigation demand = 20,000 L/day
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning calculation only. Confirm water source, pump curve, elevation, filters, pipe material, emitter uniformity, solar resource, electrical protection and local water rules with a qualified irrigation professional. Rounding and excluded real-world terms can make an external result differ.
How this farm pond rainwater-harvesting capacity calculator works
The calculator applies entered dimensions, flows and efficiencies as a transparent farm-planning estimate.
A worked example
Use measured site values to explore a realistic irrigation or harvesting scenario.
Is this a final hydraulic design?
No. Site elevations, equipment curves, pipe data, water quality and local rules require qualified design.
Calculations run on your device. Review your results before exporting or sharing them.
Use surveyed pond dimensions
Top and bottom areas plus water depth give a frustum storage estimate.
Freeboard, seepage, evaporation and sediment reduce usable storage.
