Determine the gross water supply reservoir volume for the following information: City population: 200,000 Water consumption rate: 568 Lpcd Catchment area: 103 Km^2 Rainfall rate: 110cm/yr Annual soil evaporation: 50cm Minimum net reservoir volume: 50% of annual yield or half of a year water supply whichever is greater. If during the droughts 25% of water required is supplied from a deep well field, how many deep wells with 30 liter/second discharge are required if each well supplies water for 12 hours per day.
