The invert is the bottom of the inside of the pipe. It is the major level reference level when installing pipework of civil works, ie storm water etc.
Building is a structure and civil in water, sewer, storm drains as well as roads and bridges.
The cost to build a residential road with a curb and storm sewer can vary widely based on location, materials, and local labor costs, but it typically ranges from $100 to $300 per linear foot. Factors affecting the price include soil conditions, drainage requirements, and the complexity of the design. In some urban areas, costs may be higher due to increased regulations and land value. For a precise estimate, it's best to consult local contractors or municipal guidelines.
Underground and used for storm/ sanitary disposal

My ring rolled across the sidewalk and into the storm sewer.

Any liquid flowing through a sewer either storm or waste in suspension
Storm - sanitary - combination - forced - gravity
Then some sewer workers have to get the button out of the storm drain.

There are four major types of sewage disposal systems. The septic tank, the domestic sewer, the storm sewer, and the sanitary sewer are the major types.
There are four sewage disposal systems available to the general public. The septic tank, the sanitary sewer, the storm sewer, and the domestic sewer.

There are multiple ways of stopping sewer backing up in rain storms. Ensuring there is no blocking or back ups in the piping can keep the sewer from backing up. Using generators to release excess water and allow it to flow elsewhere can prevent a sewer from backing up during a rain storm.
There is NO Sewer water in the subways only ground / storm water and the sump pumps are located at the lowest point and pumped up to a combination sewer or storm water system.=Just like the tunnels going under water=
