How It Works
Sewer line piping connects your home with the utility line
connection point, which is usually near the street. Septic piping extends from
the home to the septic system which is almost always owned by the homeowner and
located on the homeowner’s property.
Modern sewer piping is usually three, four, or six-inches in
diameter. It’s usually made from polyethylene, PVC or other plastic material.
The varying diameters are made for varying flow rates.
Sewer and septic piping is usually buried below the “frost
line”, which prevents freezing, flow stoppage and pipe cracking. Septic system
installations also involve separation tanks, lateral drainage lines, and
(depending on soil conditions) may include air pumps, water pumps, and chemical
Almost all sewer and septic piping and system
installations fall under some combination of federal, provincial, and local
building codes and other jurisdictional requirements. It is the responsibility
of the homeowner to comply with any applicable codes or requirements.
What Can Go Wrong?
The most common causes of damage are accidental physical
damage while digging, crushing under the weight of heavy vehicles and cracking
due to freezing.
