For example, sample measurements from a pump operating for the Surrey Hills house supplying all water needs in August 2008 were:
Example 2 – water pump trial for garden watering
This trial was conducted with a water pump used to water a garden, also in Surrey Hills, Victoria. The pump was run for 20 minutes, the volume pumped and the electric energy used were both measured.
|Volume pumped – litres||608|
|Energy used – kWh||0.35|
|Water usage per day (2 person household) – litres||122|
