What term describes the anticipated daily discharge from a building?

The term that accurately describes the anticipated daily discharge from a building is "design flow." This refers specifically to the volume of wastewater expected to be generated by the building over a given time frame, typically expressed in gallons per day. The calculation of design flow takes into account factors such as the number of occupants, the type of facility, and typical usage patterns, which helps in the planning and sizing of septic systems or wastewater treatment facilities to ensure they can effectively handle the expected load.

Understanding design flow is crucial because it directly impacts the performance and longevity of the septic system. An improperly sized system could lead to system failures, groundwater contamination, or health risks. It's also important for compliance with local regulations and for ensuring that the system is both effective and environmentally friendly.

The other terms such as drainage volume, projected discharge, and effluent rate may relate to aspects of wastewater management, but they do not specifically denote the anticipated daily discharge from a building in the same precise manner as design flow does.
