A sewer main is defined as the primary pipeline in a sewage system.

There are usually 4 steps involved in the construction of new sewer mains.

1. Determine the length and elevations and calculate the slope
   A Water Servicing Coordinator will design the new sewer pipe and determine the elevations, depth, length and slope calculations.
2. Dig the trench and lay the bedding
   The trench is usually dug using an excavator and must be dug on an angle to allow liquids to flow through the pipe. A slope that is too steep will create clogs and a slope that is too shallow will not provide enough velocity for proper drainage.
3. Install the pipe
   Sewer pipe is then installed one section at a time and the pipe that connects to the city main must be per the city's specifications.
4. Backfill the trench
   After the sewer main has been installed and passes inspection, the trench is backfilled.
