A truncated-pyramid-shape landfill is required to serve a community for 10 years. The community has a solid waste disposal rate of 5.0 lb/capita/day and a by-weight recycling rate of 34%. The total solid waste generated by the community over the 10 years period that is expected to go to the landfill is 1x10^9 lbs. The waste density is 1500 lb/yard3. Assume that the population, disposal rate, and recycling rate will remain constant.

Estimate the population of the community in capita.
If the waste occupies 85% of the landfill, estimate volume of the landfill space in ft3.
If the landfill height is 90 ft, and the side slope is 3, determine the dimension of the landfill in ft. (let L = W).
If the landfill has a 10-inch-thick clay barrier layer without geomembrane that holds 6 inches of liquid leachate above it and a hydraulic conductivity of 3.25x10^-7 in/s, determine the leakage rate in ft3/year.

A certain city has a population equivalent to 123456 treatment plant which will serve the community until 2040 . a) Estimate the future population of this city in 2020 and 2040 using constant percent method if the rate constant is 0.0327 /year. b) Determine the water and wastewater treatment plant design capacities for the period of 2020 to 2040. Use maximum (fmax) and minimum (fmin) factors of 2 and 0.5, respectively (Qmax = fmax Qavg and Qmin = fmin Qavg)....
