The present population of a community is 28000 with an average water consumption of 4200m³/d. The existing water treatment plant has a design capacity of 6000 m³/d. It is expected that the population will increase to 44000 during the next 20 years. The number of years from now when the plant will react its design capacity, assuming an arithmetic rate of population growth, will be
The community of San Antonio is located in the Caranavi Province, Bolivia. According to the 2005 year survey, there are 420 habitants of the community. The population is estimated to increase to 940 by the year 2035. The average peak flow is currently 1.2 L/sec and is expected to increase to 2.14 L/sec by 2035. The organic load is estimated to be 45 gram BOD5/capita-day. The community is considering a free surface wetland to treat their wastewater. (a) What is the BOD5 loading generated in the year 2035 (kg/day)? (b) Use the BOD loading to estimate the maximum surface area (ha) required for a free surface wetland that would serve the community in 2035 and remove BOD to 30 mg/L. (c) Assuming you are now considering sizing a facultative lagoon instead of a free surface wetland. Quickly estimate the required surface area (m2) for a facultative lagoon to handle a peak flow in 2035, assuming a design water depth of 4 m and a hydraulic detention time of 20 days.
a. What is the meaning of consumptive use in plants? Evapotranspiration? b. How important are the data on the efficiency of an irrigation system? c. Which of the various forms of water requirements is most important?
A small community had a population of 65000 and 85000 in the census year of 1991 and 2001 respectively. Assuming a geometric growth rate and an average water consumption of 300lpcd, Calculate the design flow for the treatment plant and the transmission mains. Select an appropriate value of design period. I will report and downvote wrong answers
The current population of a community is 40,000 capita, and the expected futurepopulation after 25 years is 100,000 capita. The current maximum monthly design flow is 10,000m3/day. An existing water treatment plant (WTP) has a maximum capacity (i.e., Qmax) of 15,000m3/d. Assume an arithmetic population increase rate, determine when the plant needs to beexpanded.
l. The diversion requirement of a 5-ha farm was estimated to be 10mm/day during peak periods. If the pumping plant has a 60% efficiency, how many kilowatt-hour energy is required to lift water 5 meters?
Problem 1A 300-house residential development is proposed. Assume that each person uses 500 liters on average eachday. Suppose that four people live in each house. Calculate how many more liters of water per day onaverage that will need to be supplied.

) Gaziantep City has P2000=1,500,000, P2010=1,750,000 and (P.F.)day=1.6. The available maximum rate of water for GaziantepCity is 420,000 m3/day. Using the Turkish Bank of Provincy extrapolation:a) Find the year until when the available water would be sufficient to meet the demands of Gaziantep City during themaximum demand day.b) Find the capacity of the distribution reservoir in m3if it is designed for the sum of 45% of the average daily demand and afire discharge of 160 lt/s lasting 12 hours.
Water at a constant rate of 370 cumecs was observed to be entering Tarbela Reservoir in a particular season. If outflow from the reservoir including infiltration and evaporation losses is 280 cumec, find out the change in reservoir storage for 10 such days. Also, convert your answer into Hectare-Meter.
Assuming a factor of safety of 2, what will be the water demand when water consumption per capita is 3.7 litres/day in a community of 6000 people and the minimum water released from a reservoir is 150,000 litres?
A planned community has a population of 63,000 people and is growing at 8.5% per decade. What is the likely average daily water demand 20 years from now? What are the annual water requirements for the city? What is fire demand? Assume the annual average per capita demand of 425 L/C-d and the . What would be the capacity that should be used for the distribution system? The monthly, weekly, daily and hourly max factors are 1.2, 1.4, 1.8 and 2.7, respectively.
