Abstract After a contract signed on May 3, 2006, Taichung County Street Dust Cleaning and Washing Program for the fiscal year of 2006 started the preliminary stage of planning and proceeded with equipment purchases and personnel training. On May 15, 2006, the program began with planned work projects including: cleaning and washing streets; inspection and coordination of the administrative offices of villages and towns; results evaluation; survey; and the actual work achievement as follows: 1. Cleaning and washing operation, and inspection: 1) After the Environmental Protection Bureau approved the planned routes of cleaning and washing, the operation officially started on May 15, 2006. During the program, there were seven route changes and four additional new routes added. A total of 12,152.8 km in length of streets was washed with 21,883.5 tons of water usage and an average of 1.8 ton/kilometer. The duration of the program was for 49 weeks, averaging 329.4 kilometers every week; compared with the original plan, the total achieved percentage was 101.3%. With 12,543.7 kilometers in length of street cleaned, compared with the original plan, the total achieved percentage was 104.5%, averaging 331.8 kilometers of streets cleaned every week. Total garbage cleared and transported was measured 171,360 kilograms, averaging 13.7 kilograms of garbage dust collected for every kilometer of street. 2) As to the inspection of the cleaning and washing operation, during the period of May 2006~May 3, 2007, a total of 284 sections of roads were inspected for the washed streets and 284 sections of roads were inspected for the cleaned streets. Judging from the inspection results, every street cleaned and washed meets the inspection standards. 2. Inspection and coordination of village and town hall: 1) In order to integrate the routes of the village and town halls which facilitate cleaning and washing machines and the Environmental Protection Bureau’s routes for achieving best efficiency, there were four job coordination meetings held for this program. Except for the coordination in details of cleaning and washing operations with every village and town offices, the meetings provided the most effective work projects and communication with every administrative offices. By sharing the experiences, it promoted the effects of streets cleaning and washing operation in the County. 2) To proceed with the inspection for the cleaning and washing operation of village and town offices in this fiscal year (once every month for those have cleaning and washing machines; once every year for those do not), website report system was provided for reporting the progress. As of now, every village and town office proceeded with the program on schedule according to their reported information. 3. Evaluation of effectiveness: Fourteen representative routes were selected for test and analysis of street dust capacity. Current rate of progress reached 100%. According to test results, the total street dust after cleaning and washing was between 0.22g/m2 and 4.76g/m2. The before- and after- tests show long-term continuous operation of street cleaning and washing can effectively improve street cleanness and the results are consistent. For example: In Dali, there are Guoguang Road, Defang Road Sec.2, Defang S. Road; in Shalu, there are Binghsin Road and Shatian Road; in Wuqi, there is Gangbu Road. The above-mentioned sections of roadway are improved to the A level roadway (clean) while the rest of roadways are B level roadway (ordinary dirty.) 4.
