Call the water and sewer company to find out how close the nearest sewer line is to your home.
Go online to your city's webpage and find the building permits section to see what permits are required for a septic-to-sewer conversion.
Call a few licensed plumbers to ask for an estimate on the price of a septic-to-sewer conversion. Ask them whether they will handle getting the necessary permits.
Pay the city's fees, which include the fee for tapping into the main sewer line and any permit fees.
Make an appointment with the plumbing company to have your septic tank drained and collapsed and for your house to be connected to the sewer line. This is a process that can take anywhere from part of one day to five days and depends on how close your house is to a sewer line and how easy it is to access the home's plumbing from underground.
