I bought an old cottage. The septic system is a cedar box about 15 feet from the house. I don't have the 10 000 to change it and would like to be able to keep it for another year or two. The water in the toilet slowly turns brown and smells after a flush. The level of the land has sunk about 12 inches over the septic and a gutter had been directed at and has been draining on top of the system. Is it full of water,full of shit, will it dry out? I have a thousand questions about this.

Kind regards
