Sewage or wastewater flow rate assumptions & specifications for septic designers: these model septic design regulations discuss sewage flow rates to be used in designing onsite wastewater treatment facilities for individual households.
This document uses the New York State wastewater treatment standard for individual household septic systems (Appendix 75-A) to provide an example of state regulated design and installation of both conventional tank and leach field septic systems and alternative septic system designs, including raised septic systems, septic mound systems, intermittent sand filter septic systems, and evaportion-transpiration septic systems.

Definition of daily design flow of wastewater
The daily design flow is the volume of wastewater that should be assumed when determining the volume of wastewater that the sewage system (septic system or soakbed or drainfield or other treatment system) must be capable of handling. "Handling" means both adequate treatment and disposal without discharge of wastewater to the surface, to nearby waterways or to other unacceptable locations.
The following table gives septic system design flow rates that shall be assumed by septic system designers, giving flows in gallons of wastewater per day per bedroom in the home served by a private onsite wastewater disposal system, that is, a private septic system. Different septic design flow rates are assumed depending on the modernity and efficiency or water usage rate of the plumbing fixtures in the home. --DF
