Question:
Determine the annual cost per megagram and the average weekly charge per household for a system using a crew of two and for a system using a crew of one for the city of Nosleep (population 361, 564).
Nosleep collection data: Number of pickups = 1 /wk (no rear-of-house service)
Average number of cans per stop = 2.53/wk at 0.1136 m 3 /can
Average number of residents per stop = 4
Mean time per collection stop plus mean time to reach next stop:
For crew of one = 0.01180 h
For crew of two = 0.00883 h
Average uncompacted density = 100.76 kg/m 3
Average observed compaction ratio = 3.97
Average transport time to disposal site including delays and dumping = 1.00 h/trip
Average number of trips to disposal site = 1/d
Rest breaks = 2 at 15.0 min
Average maintenance downtime = 24.0 min/d
Average workday = 8.00 h
Average percent of trucks out of service for major repairs = 15.0%
Labor costs for Nosleep
apaid by overhead.
Blncluded in O & M cost.
cDependent on number and type of trucks required.
Average workweek = 40 h/wk. 5 d/wk
Overhead rate = 75.04% of total crew wages
Truck data:
Capital cost of 15.0-m 3 truck = $122.000
O & M for 15.0-m 3 truck = $5.75/km
Capital cost of 21.0-m 3 truck = $141,000
O & M cost for 21.0-m 3 truck = $6.55/km
Truck compactor density rating = 400 kg/m 3
Anticipated life = 5 y Interest rate = 6.75%
Average annual distance for each truck = 11.797 km
