"YOU ASKED" What can I do if my on-site septic system develops problems?

The first thing to do if your on-site system develops a problem is to call a septic tank pumper. If having the tank pumped out only solves the problem for a little while, you'd best have a professional look at it. Get referrals for an inspector or private company to do an analysis on your system and come up with recommendations. Be aware that you may not have to have the entire system replaced. A thorough investigation should be conducted to determine the cause and extent of the problem. You will also be rquired to get a permit for any repairs or alterations that are completed on your system.
