Moving rain water to storage tank.
Moving rain water to storage tank.
(OP)
I'm looking to fill a 3000 gallon tank with rainwater captured from downspouts on half of a 15,000 sf building.
The water is for crop irrigation. We typically receive 2-3+ inches of rainfall per month and my usage between average rainfalls would likely not be more than 1500 gal. so available volume is plentiful and timely.
I want to put the tank on top of a hill above my growing areas and use gravity to pressurize drip irrigation.
At the bottom of the hill, I'll use about a 150 gallon collection tank to feed the pump.
My question is, what type of economical pump should I buy to move this water up a 1/2" poly-pipe with 150' of head-lift -a typical electric well pump or would some other type be more appropriate? Any brand recommendations and sources would be helpful too.
Thanks for any advice,
JJ

RE: Moving rain water to storage tank.
you are looking at 14,000 gallons of rainfall per month, captured in just a 150 gallon tank. At 2 gallons per minute, you can only capture 120 gallons of water in a 1-hour rainfall. The rest of the water will be lost. You either need a much larger receiving tank or a pond or a relatively high capacity pump, otherwise you will be unable to capture all the water
Until you can come up with a desired flow rate, you can't select the pump

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

At location I'm at we use the 95 percentile rain event, taken from NOAA data; turns out to be fairly close to the 2-year storm. More typical numbers may be readily available for the 90% rain event or 2-year storm due to NPDES permitting and EISA 438 requirements. A site or civil engineer could probably give better guidance.
