If construction of additional dwellings or bedrooms, the installation of water-using devices, or other factors likely to affect the operation of the ISTS can be reasonably anticipated, the system must be designed to accommodate these factors.
The estimated design flow for any dwelling must provide for at least two bedrooms. For multiple or multifamily dwellings, the design flow must be calculated according to part 7081.0120.
