Match the period
Compare energy and volume from the same observation window. Missing data or a zero denominator makes the comparison unsuitable.
Pump performance
Understanding pump energy per cubic metre of water
Learn what an energy-intensity comparison needs and why a simple calculator cannot guarantee lower pumping costs.
Pump energykWh/m³Water monitoring
How it works
What you can expect
An energy-intensity figure divides energy consumed by water delivered over the same period. In the WaterPesa example, 38.4 kWh divided by 48 m³ is 0.8 kWh/m³. This is illustrative data, not a benchmark for every pump or a measured result from your site.
Outcomes
Why this matters
Compare operating conditions
Flow, head and the service required matter when comparing periods. A smaller energy bill during a supply interruption is not necessarily an efficiency improvement.
Keep assumptions visible
A hypothetical percentage reduction and a user-entered energy price produce a scenario, not a savings guarantee or an instruction to operate a pump.
Capabilities
What the workflow includes
Record inputs
Capture meter identity, timestamps, units and quality for energy and water observations.
Inspect changes
Review maintenance and operating conditions alongside a trend.
Try a scenario
The demo calculator accepts a price and a hypothetical reduction from 0–30%.
Validate before control
A production schedule needs verified capabilities, operating constraints and local protection; no schedule is created by this calculator.

FAQ
Frequently asked questions
Does the calculator apply an electricity tariff?
No. You supply an assumed rate in the selected currency. It is not a tariff quote.
Can this automatically optimize a pump?
No. The preview explains a calculation. Automated scheduling and live commands require separate engineering and commissioning.
