contact your state and see what they require IF they allow greywater filtration systems , what those are are separate filtering systems for non black water ( blackwater is toilet ) If its not allowed there. Then there are other things you can do if you are having problems with the current septic system I would be more than happy to email you about some other things you can do that wont place you in violation of any laws anywhere , If your just having alot of trouble with current system
