The Water Well Board suggests that a minimum water supply capacity for domestic internal household use should be at least 600 gallons of water within a two-hour period once each day. This is equivalent to a flow rate of 5 gallons per minute (gpm) for two hours.Click to see full answer. Accordingly, how many gallons per minute is a good well?The Water Well Board suggests that the minimum water supply capacity for use inside a home should be at least 600 gallons within a two-hour period, or about 5 gallons per minute for 2 hours. what is a good well yield? 5 gpm (two fixtures running simultaneously at 2.5 gpm) is a good estimate of peak demand, for the typical household. Water wells that reliably yield 5 gpm should be able to meet peak and daily needs for most residences. Wells yielding less than 5 gpm, however, are sometimes the only water source available. Also question is, what is a good recovery rate for a well? Typical numbers for well recovery rates (if measured honestly over a 24-hour period) run from a fraction of a gallon per minute (a terribly poor well recovery or flow rate) to 3 gallons a minute of water flow (not great but useable) to 5 gallons per minute (just fine for residential use) to more than 10 gpm (a greatWhat is the average household water flow rate?The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.
