Two small communities, Alpha and Beta, each have a small landfill. They are considering building a joint landfill to serve both communities (Fig. 3-30). a) , Write an objective function that can be used to minimize the total cost of disposal where the towns would have the option of taking the refuse to their own landfill or to the common facility. They will not be able, however, to take the refuse to each other's landfill. Use the following variables, and state all constraints: k.c F = fixed-cost for landfill k ($100,000 per year, regardless of size); subscript c stands for capital c = transportation cost from town i to landfill k ($2/km/ton) W = refuse generated in town i (2000 metric tons per year for Alpha, and 3500 metric tons per year for Beta) F = operating cost of landfill k ($10/metric ton) Hints: You'll need to include the transportation distance in the standard objective function, since transportation cost is a function of distance. You'll need to add Fto the objective…
4. A community has a current population of 25,000. 10 years ago, the population was 18,500 and the community has a geometric growth rate. The total water consumption for the community at present is 4.0 million gallons per day. The treatment plant has a capacity of 6.0 million gallons per day. Determine how many years from now the consumption will reach 85% of its design capacity if current water usage rates remain steady.
A wastewater treatment plant receives 250 mg/L BOD, 45 mg/L NO3-N, and 0.08% TSS. What is the loading of each component (lb/d) if the plant flow is 730,000 gpd?

Q#1: Design a sanitary sewer for a City “A”, using the following data: - Population of the city = (8000) persons - Average water consumption, Qavg-water = (80) Lpcd - Industrial area, Aind = (8000) m2 - Area for commercial activities, Acom = (40) ha - Use Manning’s roughness co-efficient, n = 0.013 Diameter (m) of the sewer =? Slope of sewer = 1 in ?
Question 1 5 points Save An The city of Waterville has experienced the growth in population as shown below. Year > 1980 1990 2000 2010 Population 7300 9500 11900 14000 The per capita average daily water use (L/d) in 1990 was 300 L/d and is NOT expected to increase in the future. It is expected that the current WTP would reach its capacity in the Year 2020. For a 30 Year design period (Design Year = 2050), calculate the following A) Population assuming arithmetic increase. B) Population assuming geometric increase

A community had a population of 200,000 in 2010 and it is expected that this will increase to 260,000 by 2030. The water treatment capacity in 2010 is 43 mgd (i.e., million gallons per day). A survey showed that the average per capita water use rate was 180 gpcd. Estimate the community’s water requirements in 2030 assuming (a) no change in use rate and (b) a reduced use rate of 160 gpcd. Will expanded treatment facilities be needed by 2030 for condition (a) and for condition (b)?
Problem 2. The consumption of nitrates in drinking water is a particular concern for young children. Nitrates are a problem in agricultural areas of the Midwest due to fertilizer runoff. Compare the CDI over a one-year period for a 1-year-old child and an adult female consuming drinking water with a nitrate concentration of 10 mg/1. Use the EPA recommended values shown in Table 3-8.
