1 The speed in high-grit sewage handling systems should not exceed 12 ft/sec. 2  The flow and velocity in sewage systems with low grit concentrations should not exceed 18 ft/sec.
INFILTRATION RATE. The infiltration rate is the velocity or speed at which water enters into the soil. It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the soil surface, will take one hour to infiltrate. In dry soil, water infiltrates rapidly. This is called the initial infiltration rate.
