At an initial glance, flat surface power washing may appear to be one of the most basic and easy power washing applications for a new business to launch.
As a power washing consultant will tell you though, this is not true. "Flat surface cleaning" generally refers to pavement, asphalt, concrete, or interlocking bricks – not wooden decks. In addition, most of this type of power washing occurs on commercial, industrial or multi-family properties, such as apartment buildings, all of which present their own considerations to take into account.

Wastewater Recovery and Disposal
These surfaces and locations present some of the biggest challenges because of local ordinances regulating wastewater emissions and control. These areas often lack a vegetative buffer to absorb wastewater, and have multiple storm sewer drains that professional power washers will have to be aware of. So in addition to providing basic power washing services, a pressure wash consultant will advise you to provide for wastewater recovery and disposal.
Flat surface cleaning for automotive service locations, gas stations, and similar businesses is even more challenging as the chance of having contaminated wastewater is high from contaminants located on the surface. For example, the cleaning of a dumpster will result in contaminants such as oils, hydrocarbons, and plant/animal fats that cannot be disposed of through a standard stormwater drain.
Failure to be aware of local ordinances and federal regulations on the appropriate handling of wastewater can have expensive consequences. For example, recently a fast food restaurant contracted with a power washer to clean the area around a dumpster at the restaurant. The power washer failed to provide for wastewater recovery and disposal, and as a result, the city fined the restaurant owner $6,000 for improper disposal of contaminated wastewater.
