March 20, 1984 c cpAl,� To the Mayor and Members of the City Council W-4 Z7�s r rf XP`°f Subject: GARBAGE OOLLEK.TION ROUTE/DAY CHANGES In 1982, Ecodata, Inc., under contract to the City of Fort Worth and with the assistance of Department of Public Works Sanitation Division, ocmpleted a Refuse Collection Route Design for the City of Fort Worth and a Route Design handbook for Refuse Collection Routes in Fort Worth. The objective of the route design project was to develop collection routes using a continuous path concept that would (1) balance daily work loads between and within collection districts, (2) reduce the amount of driving required in completing collection routes thereby increasing actual collection time and saving fuel, and (3) enable more effective supervision by District Supervisors. It was recognized at that time that because of growth and other physical changes in the City, the col- lection routes would from time to time, need to be modified. The Route Design Handbook was developed to assist City staff in analyzing and ad- justing the collection routes accordingly. The Solid Waste Management Division currently provides twice weekly gar- bage collection to approximately 71,000 residential customers using thirty-five two-man collection crews. Each crew is assigned to one of three shifts, each of which works four ten-hour days during the Divi- sion's six-day workweek. An analysis of workloads for each of the Divi- sion's seventy collection routes was initiated in October, 1983, and ccrnpleted in December employing the methodology developed and provided by Ecodata in the Route Design Handbook. The purpose of the anlaysis was to determine the amount of waste collected and the number of hours worked by each collection crew during an average workweek and to apply this information to determine needed collection route/day changes to in- sure an equitable distribution of the Division's workload and efficient deployment of the Division's personnel and equipment. Weekly route averages for tons of waste collected and hours worked were compiled for routes and crews for the months of July, August, and Sep- tember, 1983. This timeframce was selected because it represents a nor- mal time during the year in terms of volume and type of waste gene- rated. By calculating the number of tons per hour of waste collected during this timeframe for the two slowest and two fastest collection districts, average tons of waste collected and hours worked on a weekly basis were determined: Average Average Average Tons/Wk Hrs/Wk Tons/Hr Slaw Crews 60.6 32.6 1.9 Fast Crews 59.5 22.0 2.7 Average 60.1 27.3 2.2 ISSUED BY THE CITY MANAGER -- FORT WORTH, TEXAS INFORMAL REPORT TO CITY COUNCIL MEMBERS No. 6922-p.2 'PT`",. March 20, 1984 5ORT� To the Mayor and Members of the City Council V-4 EX Subject: GARBAGE COLLECTION ROUTE/DAY CHANGES In analyzing tons of waste collected and hours worked cn a weekly basis, consideration was given to the fact that approximately sixty percent of residential refuse is collected on the first collecticn day of the week and the remaining forty percent is collected on the second collection day. Adjusting the preceding weekly average figures to account for this reveals the following: Average Average Tons/Day Hrs/Day lst Day Route #1 18.02 8.19 1st Day Route #2 18.02 8.19 2nd Day Route #1 12.01 5.46 2nd Day Route #2 12.01 5.46 The average tons of waste collected per day and the average hours worked per day were considered in light of the incentive system that exists in Solid Waste Collections. That is, refuse collectors are paid for four ten-hour days, but when they have completed their assigned routes and after servicing their vehicles they are finished with work for that day and are allowed to leave. Therefore, hours worked generally represent actual collection and travel time and not any break periods or other non-productive time. An indicaticn of has Fort Worth's collection system compares with that of other cities in amount of refuse collected and number of residences served can be seen in Attachment I. Two other factors other than tons of waste collected and hours worked were also analyzed prior to developing the collection route/day changes. These are the number of stops per route and the amount of garbage generated weekly by each household. A house count was conducted on each of the seventy residential collection routes. It was determined that the average number of stops per route in each of the five collection districts was 1,048 and each stop produced an average of fifty-four pounds of refuse weekly. Thirty-seven stops could therefore be approximated to equal one tcn of garbage. Using actual weekly tons of waste collected and hours worked for each route and the figure of thirty-seven stops equals one ton of waste, each route was adjusted to oonforrn to a desired 60.06 tons of waste collected and 27.3 hours worked weekly. However, realizing that such factors as the ages of crew members, haul distances from collection routes to the landfills, street conditions, the number of electric and disabled carryouts, and the density of housing significantly effect crew productivity, a range of 58 to 62 tons of waste collected and 25.3 to 29.3 hours worked per week was established as a benchmark by which to evaluate each route and determine the adjustments needed. (Actual tonnages and hours worked for each route are provided in Attachment II) .

Subject: GARBAGE OOLLECI'ION ROUTE/DAY CHANGES n Based on this analysis and subsequent findings, the following adjust- ments to the Solid Waste Management Division's collection routes are proposed at this time: 1. Reassign one-half crew fran District 5 to District 6 to better distribute the current workload and enable the Division to address growth in the Hallmark and Southridge Additions. 2. Combine Route 240 in the Commercial Collection District with Routes 250 and 251, thereby adding 150 commercial accounts and increasing the average weekly tonnages for these routes to 59.6 tons. These three routes will be serviced by one crew.) 3. Reassign one two-man crew from Commercial Collections to District 7, thus reducing weekly crew tonnages fran 65.6 to 57.4 and giving the Division same capacity to deal with growth in the Candleridge Addition. 4. Make route changes as necessary within Districts 8 and 9 to achieve desired ranges as indicated above for tons of waste collected and hours worked. A total of 4,217 residential and commercial accounts will require eol- lecticn day changes as follows in order to effect the proposed adjust- ments: Number Collection Day Changes By Collection District District #5 3,417 District #7 204 District #8 446 Commercial 150 TOTAL 4,217 Number of Charges by Collection Day From Tue/Fri to Wed/Sat 1,336 From Wed/Sat to Tue/Fri 1,905 Fran Tue/Fri to Mon/Thu 976 ISSUED BY THE CITY MANAGER -- FORT WORTH, TEXAS INFORMAL REPORT TO CITY COUNCIL MEMBERS No. 6922-p.4 y0,P,E",0 March 20, 1984 ,--� oE spAT4 To the Mayor and Members of the City Council D r Py Subject: GARBAGE COLLECTION FOJTE/DAY CHANGES fx e�3 Number of Collection Day Cis ges by Qxmcil District District #3 204 District #7 446 District #8 3,417 Bus.
