Why do wells have flow limiting devices?
Greg, it is common for a well installer to include a flow rate limiting device in the well (usually at the pump) to prevent the well pump from pumping water down low enough that the pump motor lacks water and overheats and is damaged . A special tailpiece at the water pick-up end can do this job.

What is a good well yield?
Similarly, 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.
How much water does a well recover?
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 great

How many gpm is needed for a well in Colorado?

How many gallons per day is 1 gpm?
1gpm is still 1440 gallons per day. As others have said for use without a holding tank you want 3-4 gpm. Note that this measurement is the recovery rate of the well, not the rating of the pump. In my area it varies widely, some areas you're lucky to get 2gpm, some are 20+.
What is the difference between static water level and recovery rate?
static water level in the well and the recovery rate together make the difference. static level is how much water is in the well casing when the well is not in use. this is measured in gallons. the recovery rate is how many gpm the well makes when the pump starts drawing down.
