Any city with high population is more susceptible to polluted air than those with less population. When there are many people in a particular area, it is expected that there are more pollutants to contend with. There are more vehicles, more people and more garbage to start with. That is why basic street flushing, whether mechanically or manually, is often part of the general cleaning tasks undertaken by big municipalities and cities in both industrialized and developing countries.
Toronto is Canada's most populous city and is part of the Greater Toronto Area that also includes York, Halton, Peel and Durham. Despite the fact that many people live in this area, the City of Toronto still managed to rank 21st in the world cleanest cities in the world. Thanks to the city's "Clean Roads to Clean Air" initiative, the collective effort has obviously paid off. Frequency of road cleaning tasks such as sweeping, street flushing and garbage collection are regularly done in public and residential areas.
Street flushing is a part of a bigger solid waste management initiative or a more comprehensive clean air campaign. It is one way of getting of the dirt, dust and particulate matter that accumulates everyday. It is an activity that requires planning and consistent and educated behavior.
Ontario, a highly populated province in Canada, for example, needs a solid program and deep resources to make any clean air or anti-pollution projects work. Street flushing is an integral part in the overall cleanliness of any area along with sweeping and waste collection. This is an important task because there are health implications that can be brought about by polluted air.
The route of street flushing depends on factors such as topography, population and housing density, pedestrian traffic, climate, road surface, tree density and if there are areas near the beaches, sand accumulation. Manpower needs are determined by these factors and a solid program can cover vast areas in a shorter time.
When it comes to manpower, although street flushing is done mechanically in Greater Toronto Area, the people who will undertake the task need to be aware of the health risk of their jobs. So, protective clothing and equipment must be fully provided to them by the proper authorities. Common gears are masks, gloves and work shoes.
Street flushing is usually undertaken first in public areas, the most populated area figuring on top of the list usually. The frequency of this activity is also a big factor in making the efforts pay off. It is determined by considering the type of area, how heavy the traffic is in particular areas and how educated the pedestrians are in litter-related issues. Needless to say, any street flushing tasks will get easier if people in populous areas cooperate by way of proper disposal of their trash and even by simply putting their trash in the proper bin.
The trash collection service when done frequently and reliably can reduce the need for street flushing activities. Better collection can also reduce the proliferation of air pollutants. The trucks are covered properly so spread of litter when the wind blows hard can be lessened. Airborne bacteria can easily be transferred if trash bins are just left in the open for a long time.
Evaluation of the solid waste management program as a general rule must be evaluated from time to time to determine if goals are reached in the given time frame. If the results are unsatisfactory, changing of equipment, increasing manpower or formulating new ways can be considered the soonest time possible.
