HOW IT WORKS
HOW MUCH WATER DO I NEED AND HOW HIGH?
For your zero energy Papa Pump site to be viable you must have:
A spring, stream or river with a flow of at least 50 litres per minute and the watercourse must fall to give you a Supply Head of a least 1 metre.
The Supply Head is the difference between the highest point of your watercourse and the lowest point across your land
The greater the Supply Head, the greater the amount of water you can deliver
and the higher you can potentially lift the water
Calculate with this table an approximation of how much water the Papa Pump can supply based on the measurements of its installation.
