For instance, residential sewer line depth ranges from 18 to 30 inches. However, city sewer line depths are different. Your city's sewer lines must always be deeper than the deepest residential pipe to allow waste to flow downhill. As such, these lines can go as deep as needed.
Residential sewer line pipe depths range from as shallow as 18 to 30 inches in depth or 5 to 6 feet deep. However, in colder climates where freezes occur, you often see sewer line depths ranging from 4 to 8 feet deep. This ensures the pipes are below the freeze line.
The depth of sewer lines can vary, but there are general guidelines in place. Typically, the minimum depth for a sewer line trench is around 12 to 16 inches, ensuring adequate protection from surface elements and preventing accidental damage.
Local municipalities often have sewage and property maps that can help you locate the sewer line on your property. A way to save time and effort is by calling in a plumbing expert. Not only can they locate your sewer line, but they can also provide sewer line repair and replacement services.
Ground penetrating radar (GPR) allows them to locate both metallic and non-metallic objects including PVC pipes deep within the ground without causing damage.

1/4 inch per foot is the minimum code. Technically outside the building, it can be a little bit flatter, depending on interpretation of the applicable code. Typically we design in percentages and this is a 2% slope. You don't worry about separating liquids and solids until the slope exceeds 15%.
The trench should be about 18 inches deep and 9 to 12 inches wide.
4″ waste line can support 90 DFU's, Toilets can be 3–4 DFU's depending on how many gallons per flush. So, 22 toilets if they use a lot of water.

When connecting a toilet soil pipe, it is advised to never use a pipe smaller than 100mm to carry the waste from said toilets. This size soil pipe is not designed to handle solid waste and can result in a blockage. So 110mm soil pipe is important to consider in this instance.
The optimal slope for drain pipes typically ranges from 1/4 inch to 3 inches of fall per foot of length, depending on the pipe's diameter and the type of waste it carries. The larger the pipe, the less slope it requires to move wastewater effectively.
Sewer lines come in a variety of depths. They can range in depth from 12″ to 30″ and can be as deep as 6+ ft. Often, it's only a matter of the environment and climate. They will bury the line deeper in extremely cold climates to prevent the pipe from freezing solid in the winter.
