A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
This system combines the mechanical action of the water to remove the snow and the > zero temperature of the water to melt the snow. This system can only be used where ground temperatures do not regularly drop below zero, otherwise sheet ice formation could result (although a continuous water flow would act as an impediment to this).
