There are many specific methods and tricks to go about replacing a sewer line on one's property. the best way is to call a local service and have it done professionally. This avoids danger and hassle.
Install a one way check valve in the line from the house to the sewer.
Having 2 sewer cleanouts on your property is common and allows for easier access to the sewer system for maintenance and repairs. It provides a backup in case one cleanout becomes blocked or inaccessible.
The length of a sewer line can be anything from one meter/yard to many kilometers/miles long.
"Sewer line" is typically written as two words. It refers to the pipe system that transports wastewater from homes and buildings to a sewage treatment facility or disposal area. In some contexts, you might see it hyphenated as "sewer-line," but the most common usage is as two separate words.
A sewer is a common drain line that connects multiple lines or houses that the city maintains. Septic tank is for one house that in on that property and the owner maintains.
One of three options to consider. One. Get your septic tank emptied and cleaned out completely and your sewer lines flushed. Two. There is a blockage in your line. Three. Repair or install vents on your sewer line.
Not necessarily. Property lines are established by surveys. The sidewalk may be one of the fixed points they use to establish the location of the property line, but otherwise it is unrelated to the property line.
Let's put it this way - Which one would you prefer to dig up in your back yard?
Almost everyone calls a plumber to do it. The main line can be between 4 and 10 feet deep. You have to use a back hoe to do it. It's not something you can do with a shovel.
The drain pipe has a blockage somewhere downstream from where the toilets are connected to the main sewer line from the house. All the drains in a house normally connect to one main line that either goes to the city sewer system or your septic tank. If you know where the sewer line exits the house, you could check there to see if the blockage is in the yard. Most sewer blockages are caused by tree roots, broken fittings, or crushed pipes. Good Luck

Firstly check with the Water Authority/Local Authority that the drain is not a sewer shown on the map of sewers. If it is in fact a drain it should only serve one property, however. If it is no then it might be a private sewer that serves more than one property. If it only serves one property it is a drain and in this case and in the case of it being a private sewer it will need to be protected against damage from floor loads. I suggest you ask the advice of your Building Control Deapartment at your local Council as bot both protective measure and accessibility measures may be required.
