Table 10.12 shows our input table again with the volume per flush changed to reflect
change out to a lower volume flush toilet, in this case the volume reduced from 3.5 gal
per flush to 1.6 gal per flush. (Excellent base information on usage can be found in the
AWWA end-user survey and in the U.K. managing leakage series).
Figure 10.10 shows the resultant modeled reduction in use per shift.
