Poop Aid, the collapse of our septic system

Our septic system failed and due to our HOA rules, we cannot repair it. Instead, the city of Tallahassee wants to hook our poop pipes up to their system for around Ten Thousand Dollars.  Now, if the state of Florida had not laid me off two years ago while I was 5 months pregnant this would not be a problem, but now it is and we cannot afford it.  I already coupon like a crazy cat lady to try to pay for essentials.  Please make a poop dreams a reality.
