How to determine Q of existing well
(OP)
Is there a way to determine the flow rate of an existing water well? I need to build a model of an existing water system supplied by 6 wells. I obtained the well numbers from the casing and called the well driller, but they do not have any information on the output of those wells. Is there any other way to determine it?

The well driller also should be able to provide you with an estimate of well capacity based on the output of similiar wells in the vicinty.
Your most accurate estimate would come from an experienced well driller. The answer that he provided to you does not make sense. I would go back to him and see if he can provide better information.

If well capacity, do like the above said and run a pump test.
If pump capacity, do you have a place to put a strap on ultrasonic flow meter? Or can you install a permanent flow meter? It should have one anyway.
