The world population in 1980 has been estimated at about 4.5 billion. The annual population increase during the preceding decade was about 2 percent. At this rate of population growth, predict the year when there will be a shortage of fresh-water resources if everyone in the world enjoyed the present highest living standard, for which fresh-water use is about 6.8 m/day (1800 gal/day) per capita including public water supplies and water withdrawn for irrigation and industry. Assume that 47,000 km of surface and subsurface runoff is available for use annually.

A water treatment plant in a city is to be upgraded to meet the needs of the population in the year 2025, and the water distribution system is to be expanded to meet the needs of the population in the year 2045 or 2055. The 2010-population of the city was 225000, and based on a saturation population of 2,500,000, the 2070-population is estimated to be 420000. Estimate, using decreasing rate of increase method, the city's population in 2025, 2045 and 2055 to facilitate the design of these systems. Don't attempt wrong
