SECTION -3
ANALYSIS AND SELECTION OF WASTEWATER FLOW RATES AND CONSTITUENT LOADINGS

Reliable data for existing and projected flow rates affect the hydraulic characteristics, sizing, and operational considerations of the treatment system components. Constituent mass loading, the product of constituent concentration and flow rates are necessary to determine the capacity and operational characteristics of the treatment facilities and ancillary equipment to ensure that treatment objectives are met.

WASTEWATER SOURCES AND FLOW RATES
Data that can be used to estimate average wastewater flow rates from various sources include:
1. Domestic sources
• residential areas
• commercial districts
• institutional
• recreational facilities
2. Industrial sources
3. Infiltration/Inflow contribution
? DOMESTIC WASTEWATER SOURCES AND FLOW RATES
The principal sources of domestic wastewater in a community include:
1. residential areas
2. commercial districts
3. institutional
4. recreational facilities
Water consumption records may be used for estimating flow rates. The average about 60 to 90 percent of the per capita of water consumption becomes wastewater.
? RESIDENTIAL AREAS.
For many residential areas, wastewater flow rates are commonly determined on population and the average per capita contribution of wastewater. See Table A-9
