Cleaning the parking lot is done in order to improve and enhance its appearance. The pollutants that accompany the runoff may be minimized if the parking lot flushing activity is done properly and regularly. The silt, dirt and debris that are naturally present in a parking lot must be removed not only to make the place look clean and properly groomed but to prevent any form of accidents and reduce the entry of any hazardous and toxic elements into the storm drains that are located within the parking lot area.
The Greater Toronto Area which is a bustling place and has a large population has many parking lots located within its vicinity. Making parking lots safe in the GTA by using parking lot flushing as a means of cleaning the surface pavements ensures that oil leaks and spills coming from the machines and brake linings of the parked vehicles are cleaned out. Once this oil or lubricant spills accumulate they make the parking lot look unsightly and slippery. Tires may skid on it and vehicle owners or pedestrians walking through may slip and hurt themselves. Hence, regular parking lot flushing activity by using a strong pressure of water to eliminate the oily substance overrides the big possibility of any dangers and accidents.
The exhausts from the vehicles which come into and go from the parking lot usually form hydrocarbon elements with the dust, silt and sand present on the pavement. This accounts for the increase chances of water mains being polluted through the storm drainage system because of the network of interlinked pipes that are below the surface. To reduce large quantities of such pollutants, the regular parking lot flushing activity is necessary.
While parking lot flushing may be deemed by some as only pushing the dirt off the surface pavements and leaving them on the sides of the sidewalk, the cleaning of the parking lot does not necessarily end there for it also requires sweeping up any debris left by the water flushing.
Sediments and sands that tend to accumulate on the surface of the parking lot which are not cleaned out are often brought by the parked vehicles' wheels/tires somewhere else once it leaves the parking and this add to the dirt and pollution somewhere else in Ontario. The tires of the vehicles are not the only culprit in the distribution of such dirt, grime and dust elsewhere in the locality but also passersby who happen to step into the unclean pavements of the parking lot.
Parking lot flushing needs a large volume of water with a high pressure to be affective. While this may be considered as an additional expense because of the machine or tools needed to implement the cleaning, the advantages of not having any form of accidents on the parking lot due to accumulated dirt and debris is a good evidence of regular and efficient maintenance.
And while water conservation could be pointed out as an issue in using water flushing to clean, the appropriate scheduling of cleaning the parking lot will reduce the high cost of water. And if cleaning is done properly and meticulously, every drop of water which is used in order to cleanse the area could be considered as well accounted for.
