Pressure washing is a highly effective method for cleaning a variety of surfaces, from driveways and sidewalks to decks and siding. However, once the cleaning process is complete, you may find yourself faced with the issue of dealing with the dirty water left behind. It’s important to properly dispose of this water to prevent environmental damage and ensure compliance with local regulations.

First and foremost, it’s crucial to avoid letting the dirty water flow into storm drains, as these drains typically connect directly to local bodies of water such as rivers and lakes. The chemicals and contaminants in the dirty water can pollute these water sources and harm aquatic life. Instead, consider diverting the water to a grassy area or a garden, where it can be absorbed by the soil and filtered naturally.

In some cases, you may need to use a sump pump to remove the dirty water from your cleaning area. A sump pump is a device that can efficiently remove water from a designated area and redirect it to an appropriate drainage system, such as a sewer or a septic tank. This method can be particularly useful if you’re dealing with a large amount of dirty water or if you’re pressure washing in an area without easy access to natural drainage options.

Another option for handling the dirty water is to collect it in a containment system, such as a large plastic tank or a specially designed water collection device. These systems can be connected directly to your pressure washer and will capture the dirty water as it’s generated. Once the cleaning process is complete, you can then transport the collected water to a designated facility for proper disposal or treatment.

Remember, when pressure washing, it’s essential to be mindful of the environmental impact of your actions. By taking the necessary steps to remove and dispose of the dirty water properly, you can ensure that your cleaning efforts are both effective and eco-friendly.
