Reclaim system on a well/septic self serve wash?

[KTM300]

My dad built our wash 15 years ago while I was in college. It is a two bay self serve next to our grocery store/gas station. We are in rural location, so we are on a well and septic tank system. He was a sold a Rowafil reclaim system. At the time I wasn't involved in any of the design decisions. I am now in charge of the car wash. Does it make sense to use a reclaim system when on a well and septic? I have no idea how much water we really use, because none of it is metered. We gross between $800-$1800 a month depending on the season, if that can give you an idea of our water use.

If the well has a limited draw you might need it, otherwise I see no benefit and lots of potential issues.

If well water is unlimited or you could utilize a cistern, I would not reclaim.

I know there have been some reports of Legionnaires' disease caused by carwash reclaim systems. There was a significant outbreak in either New Zealand or Australia but I cannot find the article online. i did find a report of 2 people getting Legionnaires' disease in Italy this year that was blamed on a carwash.
IIRC, the incident in NZ/AU was at a SS only wash. My understanding was that the reclaim water droplets can enter the lungs of the customer in a SS but in an IBA the customer is protected because they are inside a car.
TO BE CLEAR, I'm not trying to claim that reclaim systems are dangerous, they are in wide use here in the US, but there may be issues or additional costs in trying to use reclaim in a SS.
