Estimate the life of a landfill for a user population of 10,000. The available area for the are-type landfill is 10 acres. The water table is estimated at 6.1 m (20 ft) below the ground surface. The pit must have side slope of 1:3, and the final surface must have a slope of 1:4. Assume that soil (used as daily cover) occupies 20% of the compacted volume of waste

Determine the area (m2) required for a new landfill site with a projected life of 10 years for a population of 100,000 generating 2.00 kg/capita-day. The density of the compacted waste is 400 kg/m3. The height of the landfill cannot exceed 10 meters.
Estimate the life of a landfill (years) given a population of 250,000 people, 40 acre, a maximum depth of 50 feet below ground, a pit slope of 1:3 and final slope of 1:4. The coversoil occupies 22% of the compacted volume. There is a 42% diversion rate, the waste is compacted to 1,270 lb/yd3, the population is stable and generates 6.2 lb/capita/day. The landfill area is square and the max height of the landfill is 33 yd.
List the 5 critical elements of a municipal landfill based on many current State requirements.
A sanitary landfill is being designed to handle solid waste generated by the town of Pietro, at a rate of 40 Mg/day. It is expected that the waste will be delivered by compactor truck on a 5 days/week basis. The density as spread is 129 kg/m3. It will be spread in 0.8 meter layers and compacted to 0.3 meters. Assuming 2 such lifts per day and a daily cover of 0.13 meters, box your answer the annual volume of landfill consumed in cubic meters. Ignore the soil volume between the stacks. Answer in two decimal value.Also In your solution Compute also the daily horizontal area covered by the solid waste.
A leachate collection system is being designed for a 10 acre landfill. If the drainage rate through the waste to be collected in the perforated pipe is 1.5 inches/day, determine the expected leachate from the landfill in ft3 /s.
Secure landfills require all but ONE of the following? a. Single liners b. Ground water monitoring C. Financial guarantees for post closure activities d. A Leachate collection system
State FOUR (4) factors to be considered in landfill design
1. What is the hydraulic gradient between points A and B. 2. What is the minimum elevation of the waste cell. 3. Estimate the travel time for contaminants to reach point A if the protective liner of the landfill cell fails and contaminated liquid seeps into the groundwater.
How many cubic yard of solid waste can be placed on a regulation soccer field (200 ft × 300 ft) subject to the following constraints and conditions? Slope of all landfill faces = 3 to 1 Covered material will be excavated from the site Neglect cover material requirements Lift height = 10 ft Maximum height of landfill = 20 ft Waste generation rate = 4.1 lb/capita day Community population = 80,000 How many soccer fields would be required per year to dispose of the waste from the community, assuming the in-place specific weight of the waste is 1,000 lb/yd3?
1. A sanitary landfill has available space of 16.2 ha at an average depth of 10 m. Seven hundred sixty-five (765) cubic meters of solid waste are dumped at the site 5 days per week. This waste is compacted to twice its delivered density. Draw a mass balance diagram and estimate the expected life of the landfill in years.
List THREE (3) characteristics of sanitary landfill that differ from open dumping.
