Figure 2-22.—Types of manholes
When designing a wastewater system, the design
water is not constant. Use is greater in the summer than
engineer begins by first determining the types and
in the winter and greater during the morning and evening
quantities of sewage to rehandled. This is accomplished
than it is in the middle of the day or at night. Therefore,
through a careful study of the area to be served. The
design engineer bases his design on the average daily
the average daily flow (based on the average utilization)
use of water per person in the area to be served. A typical
is multiplied by a peak flow factor to obtain the design
value is 100 gallons per person per day. But, the use of
flow.
