Comprehensive Review of S olid W aste Collection and Disposal Options v2.1 84 10/22/12 6.3.1.5 Existing Fleet Summary and Projected Replacement Schedule As described in Section 4, presently the Town residential collections program maintains seven (7) front line, tandem-axle, rear loader, compactor trucks and maintains four (4) single-axle, rear loader, compactor trucks in a reserve fleet. For the current FY 2012-13, the SWSD is budgeted to operate six (6) residential collections routes; however, the division has continue to operate seven (7) residential routes as it has done in past years. This analysis notes that the current resource allocation is a reduction from the previous fiscal year, FY 2011-12 when seven (7) collection routes were budgeted. The budget reductions in FY 2012-13 were based on positions being held vacant and the knowledge that a budget amendment would be needed ones collection improvements were established based on results from this Study. Review of the Town collection vehicle data indicates the Town has consistently replaced and updated its front line (i.e., primary) residential fleet with tandem-axle vehicles, while maintaining the older, single-axle vehicles to be engaged when any of the front line vehicles are out-of-service.  The oldest tandem-axle truck was purchased in December 2005;  The next oldest truck in 2007;  Three (3) trucks were acquired in 2008; and,  The two (2) newest trucks were purchased in 2011. For the purposes of projecting on-going capital expenditures for fleet replacement, the analysis assumed that collection vehicles will be replaced on a 7-year operating schedule. The Town commercial collections fleet is comprised of: two (2) front line, tandem-axle, front loader compactor trucks purchased in 2010; and one (1) backup tandem-axle, front loader compactor truck purchased in 2004. Similarly, SCS has assumed these commercial collections vehicles will be replaced over a 7-year operating schedule. 6.3.1.6 Fleet Routing and Modifications To accommodate the current residential collection volume, collection practices, routing configuration, and Town resource allocation, as well as to enable compliance with the NCDOT weight limits, while maintaining the same level of service to Town residents, SCS recommends the Town conduct a formal routing study to thoroughly evaluate all of these factors and most efficiently configure collections routing. SCS recognizes that an infinite number of routing and resource scenarios may be considered; however for the purposes of this comprehensive study we evaluated the following scenarios:  Seven (7) collection routes 2 days per week; or,  Six (6) collection routes 3 days per week. A cursory analysis of the Town’s residential routing scenarios based on the most recent annual residential MSW disposal (FY 2010-11) and current vehicle collection capacities presents the projected minimum routing configurations for the referenced compacted load density depicted in Exhibit 6-3.
