ANS:C - Inlets are generally provided in all sewers

Inlets are generally provided in all sewers. Inlets are not generally provided in all sewers. Inlets are typically installed at specific points along sewer lines to allow surface runoff, stormwater, or other forms of drainage to enter the sewer system. However, they are not necessarily present in all sewers. The presence of inlets depends on the design and purpose of the sewer system, as well as the local drainage requirements and conditions.
