About rain water harvesting essays

Consider for a moment how much rainwater some cities may receive during a year. For example, Atlanta, Ga. averages about 45 inches of precipitation per year; multiplying this by the billion gallons shown in the table as the number of gallons in 1 inch reveals that some billion gallons of water fall on Atlanta in an average year. In a city the size of Atlanta, the per capita water use is about 110 gallons per day or 40,150 gallons per year. Thus, the water from a year's precipitation, if it could be collected and stored without evaporation loss, would supply the needs of about 2,574,000 people.
