and their resident dependents. This should include hospital
in-patient personnel. Estimate nonresident population by adding
existing and proposed nonresident populations, which can include
the following people:
a)
Non-resident military, calculated by subtracting
the resident military from the total military strength
b)
Civilian personnel under Civil Service or
nonappropriated funds (NAF)
c)
Personnel from other services, foreign military,
or nonmilitary tenant organizations
d)
Contractor personnel (for example, base
maintenance and custodial)
e)
Daytime schools
f)
Daytime transients

Domestic Flows, Annual Average. If no wastewater flow
data exist to determine per capita unit flow factors, calculate
domestic flows as follows:
For estimating flow, use:
Resident population
=
100-120 gallons per
capita per day (gpcd)
(378-454 liters per
capita per day (Lpcd))
Nonresident population
=
30-35 gpcd
(114-132 Lpcd)
3.3.2.3
Domestic Flows, Maximum Daily Flow. To determine the
maximum 24-hour flow, use the following procedure:
a) Multiply the annual average flow by the ratio of
maximum daily flow to annual average flow based on wastewater
flow data for the facilities being studied. If no data are
available, see Chapter 3 in WEF MOP FD-5 for methods of
estimating typical domestic wastewater ratios in various
geographical regions. Designers are cautioned to carefully
consider the impact of resident and non-resident populations and
