The project has completed the following main events and the results describe below:
1. The completed washing length of streets was 35,227.4 kilometers, and the sweeper length was 14,835.5 kilometers , and the compact sweeper length was 5,461 kilometers. The completed cleaning length of streets was 55,523.9 kilometers.
2. The total water consumption for streets’ washing was 37,581.64 tons. The water used per month was 1.04 to 1.10 tons/kilometer, and average water used per month was 1.07 tons/kilometer.
3. The collection of street dust amounted to 94.39 tons, The street dust per month was 1.35 to 8.70 tons.
4. The streets washing task was completed 35,227.4 kilometers, and the estimating reduction of suspended particulate matter (TSP) was 486.1 tons. The sweeper task was finished 14,835.5 kilometers,and the estimating reduction of TSP was 204.7 tons. The compact sweeper task was finished 5,461 kilometers, The estimating reduction of TSP was 75.4 tons. Hence, the streets cleaning operations of the project could reduce TSP about 766.2 tons.
5. The plan promoted 47 businesses to join the Yunlin County Adopt-A-Road program. The total execution length of adopted road amounted to 11,607.45 kilometers, and the estimating TSP reduction was about 160.18 tons.
6. In order to improve paving pollution resulted from agricultural machinery during farming season. We staged six workshops of paving pollution prevention for rural communities which have larger harvest areas (attended persons total 546).
7. The plan executed general survey of streets pollution grade for 2,259.5 kilometers (streets surveyed total405) from december 2019 to June 2019. The major result showed the streets pollution grades of Yunlin County was A.
