Given emerging technology â and a contracting economy â health plans are looking hard at whether carve-outs for pharmacy benefits, disease management, specialty pharmacy, and behavioral health care are worth the money.
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.
pipe leaving the structure will be aligned with the soffit of the largest pipe entering the structure. These are the minimum elevation drops. On steeper grades, it may be necessary t o make elevation drops larger in order to reduce the slope and keep water velocity under the scour velocity (15 ft/sec). Minimum Pipe Slopes Pipe velocity sets minimum slopes for storm sewer. However, for construction purposes, a slope greater than 0.4% is preferred. Initial estimates may use the average slope of the ground unless this
