Why do I live in the city and I'm still on a septic system?

Actually I don't know how much this has to do with a recent plumbing problem, but I have always thought it was weird that we have a septic system and well water and live 43 blocks from the middle of a metropolitan city. I know we are scheduled to be converted in the next few years but why did it take 50 years for that to happen? Questions I will probably never know the answer to. Adam was excited that we were on well water because it reminded him of being in the country, I also grew up on well and septic, so I suppose it is fine.

On to the plumbing problem I briefly mentioned. For some reason the water in the drainage line for the south side of the house is not adequately draining or not draining fast enough and causing back-ups, especially when using the washing machine. Adam spent one evening underneath the house ripping out some of the old cast iron and replacing it with PVC and also making sure the drainage was at the proper angle leading out to the septic line, that has been to no avail. He also looked down the septic line with his flashlight and didn't see an clogs or anything and said he could see for a long way, plus there wasn't any extra water in the septic line coming back to the house, so that wasn't it either. He then spoke with a guy at Economy Plumbing (his plumbing store of choice) and they said it sounded like something was clogging one of your plumbing vents so that lack of air release wasn't letting the water flow fast enough and thus the back-up. So last night my husband climbed on top of our house with the shop vac and try to shop vac out anything potentially in the vent, that had to be interesting to our neighbors. He did get an acorn and thought that was the culprit, but we were still getting the back-up. I don't know what the next investigative step is, but I'm thinking perhaps a professional plumber might not be too far down the list.

Needless to say this has delayed our putting up trim, and thus getting the carpet. Hopefully we will get back on track with that soon. Sorry no pictures, but I don't really think you would want to see the garbage disposal food that was trapped in our line then came out and went all over the floor, and the picutre definetly would not have conveyed the smell!!!
