Well,,,,,city people moving into the country can create problems,,[what did you say,watering acres of new yard on a water well??]crazy to begin with,than those water cleaners that flush use a whole lot of water to do that too,,
We got two wells,but we would be replacing pumps every year if we tried to do what some do,,guess it all depends on your well and where you live,but here that stuff wouldn't work,,[except for a lucky few],,not for your neighbor but for you. And maybe he will learn that real quick where you're at too.
I grew up with hand pumps,,you wouldn't be watering a acre yard with a hand pump

,,we never ran out of water and wells were sometimes[mostly] older hand dug wells,,but modern times is here,electric pumps,ones that pump what,30 gal a min?untill they run out of water to pump,,but,,still the same water source that we used to hand pump out of and drop buckets down into[well,maybe even less of a water source in many cases.]
We of course like every body else,use alot more water than we did when I was growing up,but even now,with two water wells,I don't water my yard or my garden or wash cars,or in general,use any more water than I have to out of those wells,maybe 150 or so gal a day,,bet we didn't average 50 gal a day when we was hand pumping it,most days except wash day,probably didn't use more than 20-30 gal[no inside tolet,no shower or bathtub,no dishwasher,etc]
When you move to a location without city water,city sewer,,you got to make adjustments to your water useage.
