Water Consumption Rate: 80 liters per capita per day
Unit Consumption (Institutional): 1.0 m3/day
Unit Consumption (Commercial): 0.8 m3/day
Average Daily Demand (2015):= 57680 liters per day = 0.6676 liters per
second
Average Daily Demand (2032):= 76480 liters per day = 0.8852 liters per
second
Projected Water Demand (Domestic) = 0.8852 liters per second =
76.4813 m3/day
Total Projected Water Demand = 76.4813 m3/day + 1 m3/day + 0.8
m3/day
= 78.2813 m3/day
