A city has 3,400,000 capita and current domestic demand is 185 liter/capita/day. The population average increase is 20,000 capita per decade; and the increase is also estimated as 1.35%. The average consumption of water increases by 22% in summer and decreases by 18% in winter. There are industrial and commercial activities in this city. Forecast future population by two methods. Calculate the average domestic demand for this city after 50 years in normal, summer and winter days. Estimate the firefighting demand. Then calculate total average water demand. Finally determine the maximum hourly and maximum daily demands.

Q1: A small river is to be used as source of water supply for a small community. The minimum flow in this river is 550 m/h. The population analysis reveals that the population is expected to increase linearly from a population of 10,000 in 2020 to 30,000 in 2050. The water consumption of the community is estimated to reach an annual average demand of 300 Lpcd. Would you be able to supply this demand directly from the river in the years 2020 and 2050? If not, till how many years the river would be able to supply?
A town uses water from a reservoir that holds 200 million L and is replenished at a rate of 60 million L a day. In 2020, the town used 46 million L per day, calculate the average water use per person per day. (Town population: 70,230)
A water company wants to check that it will have sufficient water if there is a prolonged drought in the area. The region it covers is 500 square miles and various different offices have sent in the following consumption figures. There is sufficient information to calculate the amount of water available, but unfortunately it is in several different units. Of the total area 100 000 acres are rural land and the rest urban. The density of the urban population is 50 per square kilometre. The average toilet cistem is sized 200mm by 15in by 0.3m and on average each person uses this 3 time per day. The density of the rural population is 5 per square mile. Baths are taken twice a week by each person with the average volume of water in the bath being 6 gallons. Local industry uses 1000 m3 per week. Other uses are estimated as 5 gallons per person per day. A US air base in the region has given water use figures of 50 US gallons per person per day. The average rain fall in lin per month (28…
A reservoir is proposed for a city’s water supply. It has been sized so that wet season flows can be saved to provide water in the dry season. The population of 100,000 and the economic activity in the city are stable – no substantial change is expected for the next 20 years. The per capita water demand was taken to be 300 liters/person/day, and it does not change by the time of year. Based on 30 years of historical river flow data and the projected monthly demand for the next 20 years, it is estimated that a storage equal to 4 months of demand is adequate. a) What is the storage capacity of the reservoir? b) The capital cost of providing the storage is $20/m3, and the annual operating and maintenance cost is 5% of the capital cost. The maximum the residents are willing to pay for the water is $2/m3. What is the projected rate of return on this investment over the 20 years project plan.

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

A community has an expected future population p= 180400 capita after dt= 23 years and a present population po= 66600 capita and the present maximum monthly water consumption wc.= 6270 m³/day. An existing water treatment plant has maximum capacity of 16500 m³/day. Assume the arithmatic growth rate of population increases method . Assume the peak factor of maximum monthly demand is 140% of the average demand . The water treatment plant needs to be extended after 3.7years 10.4years 22years 1.3years 18.6years years.
