An important reason to sweep your parking lot is asset management. Sand, gravel, dirt, oil, trash and debris collect on the surfaces. Driving across a lot or road with this type of debris acts like an abrasive, which deteriorates the pavement exponentially. This same sand and dirt collected on the bottom of shoes or a shopping cart will accelerate the need for routine floor care inside the property as well. These same conditions left untreated can cause trip and fall hazards outside as well as inside of the facility. Maintaining the property with a regular sweeping routine can help mitigate any possible liability.
While Asset management and safety are important reasons to perform power sweeping, the environmental concern is just as valid. Storm drains catch runoff that contains pollutants and materials that work their way into our local waterways and storm systems. The accumulation of potentially hazardous materials in our natural resources will have residual effects on our health and the environment. Regular sweeping can break the cycle of pollutants in stormwater runoff.
