Notes on the use of table 3-1.
1. Allowances do not include industrial and process wastes as defined in Chapter 3 of TM 5-814-8.
2. These values represent domestic waste quantities for resident personnel averaged over the entire installation for a
24-hour period. Nonresident personnel and civilian employees working 8-hour shifts will be allowed 115 liters/capita/day
(30 gallons/capita/day). Normally, these quantities are to be used in design of wastewater treatment facilities as indicated
in Chapter 4 of TM 5-814-3/AFM 88- 11, Volume 3. However, they will also be used for sizing interceptors, trunk sewers
and pumping stations serving large portions of the installation.
3. For design of sewers serving smaller areas where several buildings or a group of buildings must be considered, the
appropriate wastewater allowances shown in the table or obtained from standard textbooks will be used.
4. In family housing areas, each housing unit will be assigned 3.6 residents for the purpose of calculating populations.
5. For hospitals, no separate allowance will be made for nonpatients and employees working shifts.
(3) Average hourly flowrate. When designing sewers to serve small areas of the
installation where several buildings or a group of buildings are under consideration, and where
the majority of wastewater is generated by nonresidents or other short term occupants, the
average hourly flowrate will be used. The average hourly flowrate will be computed based on the
actual period of waste generation. For example, 1000 nonresidents at 115 Lcpd would generate
115,000 liters in 8 hours for an average hourly flowrate of 14,375 L/h or 345,000 L/d. Note that
