I can give you several sentences.The sewer smells horrible!The Roman sewer is large enough for people to tour.They had to climb down to clean out the sewer after the flood.
Toxic Clean up is called in HAZMAT
A clean out no it isn't is has the word man in it! its called a manhole
An opening to a main sewer depending on size can be a simple clean out or a man hole cover to allow maintainable of the system (storm /sanitary /combined)
None, to properly maintain a sewer, soil, waste, storm, line water jetting is the best way to go
The obvious and main problem (and reason to keep your sewer lines clean) is because a backed-up sewer line means that sewage can get backed up into sinks and bathtubs. This is unsanitary and a health hazard. A broken sewage line is costly to repair.
A 3 or 4 inch pipe sticking straight up out of the ground? This is the clean out for the sewer line. If sewage is coming out of it, this means the sewer line is clogged or collapsed from there to the main city sewer. If you have a septic tank, the tank is full and needs to be pumped out.
All clean outs have to be accessible or what is the purpose of installing them? They can be placed behind an access door or under a floor plate
Some duties of sewer contractors are repair, install, clean and service of sewers. Contractors must also have proper insurance and licenses before working.
