Q1: A mid size city with populations of 62000, 70000 and 81000 for the years 1990, 2000 and 2010, respectively. Water consumption prediction is 400 Lcpd as domestic demand. Each of public use, losses, industrial and commercial water demand is 10% of the total water demand. Using the Incremental Increase Method, and assuming duration of fire flow is 10 hrs/day determine:- - Total average daily water demand at year 2015. - Max. weekly domestic water demand at 2015.
a community has an estimated population 20 years hence which is equal to 35,000. The present population is 28,000 and present average water consumption is 16 X 10^6 liters/day. The existing water treatment plan is 5MGD. Assuming an arithmetic growth rate of population growth. Determine in what year the existing plan will reach its design capacity.
4. The government will build a waste water piping network in District A with a design period of 10 years. It is known that District A has a population of 3000 * 5 in 2020. a) Calculate the population of District A to be served in 2030 using the geometric population projection method, if it is known that the population growth rate is 3%. b) Calculate the design discharge of wastewater in m3/s in 2030, if it is known that the level of drinking water consumption is 100 liters/person/day. (peak factor can be calculated based on the Harmon Peaking factor formula)
Question 2 5 points The following is relevant water demand information for the town of Goodborough for the design year of 2050: Design Population = 10000 Annual average per capita water demand = 250 L/d Assume a water supply system of Type C is considered for the town, as shown below: Elevated Storage WTP HLP LP Smce Community camouners) Assuming that BOTH equalization storage AND fire storage provided are sufficient, determine the following to meet the water needs of the community in the design year, as per Ontario guidelines A) Design capacity of the WTP (in ML/d; ignore losses) B) Design capacity of Conduit III (in ML/d)
A community had a population of 150,000 in 2010 and it is expected that this willincrease to 220,000 by 2030. The water treatment capacity in 2010 is 43 MLD (i.e., million litersper day). A survey showed that the average per capita water use rate was 220 Lpcd. Estimate thecommunity’s water requirements in 2035 assuming (a) no change in use rate and (b) a reduced userate of 160 Lpcd. Will expanded treatment facilities be needed by 2030 for condition (a) and forcondition (b)?
15. Shown below is a set of effluent BOD data from a treatment plant. The plant's permit requires that the weekly average BOD be less than or equal to 20 mg/L with a 90% probability. State whether you think the plant is meeting the requirement and provide appropriate calculations to support your conclusion. Data: 19, 17, 13, 16, 22, 15, 20
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…
Can I get a thorough step by step for the following question? A residential development of number of houses is being planned. Assume that American Water Works Association (AWWA) average daily household consumption (440 lpcd) applies and that each house has 4 residents. The estimated average daily water production is 528,000 L/d that is supplied by the city. Estimate the number of houses were served by the city.
