Is it cheaper to pump water or buy it?
Considering a height difference of say about 15 feet would it likely be cheaper to pump water from a lower elevation (such as a creek or pond) to a higher elevation or would it be cheaper to fill the reservoir with city water which is already under pressure. This is all just theoretical but would the cost of running the pump be more or less than the cost of buying the water? Of course other factors would play in such as the city water being bacteria and sediment free (in theory) but im ignoring them for now. Any insight would be appreciated since I have no idea of relative costs for either right now.?
Edit: Maybe I made it seem a bit too formal but I am just talking about putting a pump in a lake or creek with a garden hose attached vs turning on a garden hose connected to city water. Im not trucking it in or anything. I dont have specifics as said but if the answer depends on specifics then that gives me enough of an answer to know that i will need more research when ready and that its not easily one or the other. Thanks.
