Should there be standing water in the sewer pipe to the street?
No, there shouldn't be any standing water in a sewer line, this is what creates bad bacteria and disease. All waste needs to go down a sewer line and disappear ito the street sewer line. If this is the case, either you have a slight blockage or the sewer line gradient is incorrect. The correct ratio for the gradint of a sewer line must be 1:40 (meters) simpler measurement for slope is 1/4" per foot(ideal). absolute minimum 1/8" per foot(not recommended except where not avoidable)

What is the self cleansing velocity for a drain?
the minimum velocity at which no solid get deposited in the invert of the sewer. while designing the sewer the velocity should maintained such that no solid get diposited in the sewer. in case of separate sewer a min. velocity of .6m/s should be maintained. it should less than .75m/s in case of combined sewer, .9m/s would be acceptable.
