Many new homeowners get recovery rate (measured in gallons per minute or “GPM”) and well “storage” confused. Remember when a well driller refers to gallons per minute, this is the rate that the well is recharging or recovering at AFTER the “storage” has been pumped off.
What is well “storage”? Think of it like a reserve tank. The volume of water stored in a well is noted by subtracting the static level from the total depth and multiplying the result by the well volume per linear foot.
For Example – Say you have a 150’ 6” diameter water well. The static level of the water is 12’ from ground level. 150’-12’= 138’ of water storage. To get to gallons, know that 1 linear foot of 6” diameter pipe holds approximately 1.5 gallons of water. So, 138’*1.5 gallons/ft= 207 gallons of water storage.
So how much water do I need to effectively run my home? A general rule of thumb is having enough water available to meet peak demand for 1 hour. Peak demand is the simultaneous usage of multiple water outlets during the morning and night. Peak demand can vary drastically depending on family size, size of the home and schedules. On average, two 2.5 gpm fixtures running at the same time for 60 minutes would result in 300 gallons of water used in that time frame. The well system needs to be capable of yielding this amount of water either from well storage, well recovery rate or a combination of the two.
To answer, the average home requires about 300 gallons of water storage or a well recovery rate of 5 gallons per minute.
There are many wells in Chautauqua County that do not provide sufficient flow or storage. Lower producing wells may require storage tank systems in order to meet peak demand.
