Its quite a big piece of land and it's fully irrigated, so we have a Japan made fireman's pump with in theory a max discharge capacity of 2400 liters per minute @ 8 bar. This is run by a 5000 cc diesel engine and we have four inch water pipes running underground throughout the plantation. We need to service the pump, take it away to be dismantled and rebuilt as we are not reaching that max capacity and there is always some air in the system, but for that we would need a couple of weeks of regular rainfall to feel safe. Also we run the engine slowly so as not to use up too much fuel. What's good with these new green sprinkler heads is that they have a large hole that doesn't get blocked easily by the usual green algae deposit. We usually irrigate through 3-400 sprinklers max at any one time, which pushes the muck out. Its not nasty on the plants by any means.
