So I'd remove the tap or put a lock on the tap that's outside your garage, or lock the electric panel and shut off the pump so they can't access it for use.Water is expensive and you can call city to find out cost so if you decide to let the HOA use the well I'd get your HOA fees credited or have the HOA pay you direct..Your electric for running the pump is an expense, and I bet they've used it season long to refill pool when needed.
