My house used to have a septic system that flowed to the back yard. The previous owner abandoned the tank and put a grinder pump in to move the sewage from the back of the house to the front. I checked with the city and the sewer main is 11 feet deep in front of my house, my basement is 8 feet deep and my house sits about 6 inches lower than the street. The distance from my house to the main is 55 feet. I was wondering if I could reroute my basement plumbing to exit the front of my house and tie directly into the city sewer and eliminate the grinder pump. Also, the pump works fine but the basin has a split in a seam at the top. A plumber estimated $8,000 to $10,000 for the basin to be replaced.

sounds like no problem to me.
minimum pitch for a sewer 4 inch and above is 1/8 inch per foot.

Your basement piping may be too deep to connect to the sewer system. Where does the grinder pump's discharge go now?

Hi hj,
The pump discharges at the street. I have a walk out basement and the house drains to the back so the current drain is 3 feet below ground which makes it 11 feet below the street. I would like to break up the basement floor and slope everything to the front if it is possible. All the fixtures in the basement are at the front of the house and the total distance the line would go is 63 feet from the main stack the the street.

The critical dimension is HOW DEEP the piping would be and whether it is above the sewer in the street sufficiently. Another factor is the depth of the branch at your property line since it may NOT come off the side of the main line.
