<br /> Water Balance Calculations for High Annual Rainfall
<br /> Table 5.2 presents the results of the water balance calculations based on the same process flow
<br /> rates as above and projected storm water flows in a 100-year annual rainfall year. The water
<br /> balance calculations show that the system is adequate to accommodate the current summer and
<br /> crush wastewater flows as well as in 100-year annual rainfall winter months.
