Pressure washing is a highly effective method for cleaning surfaces that have been left to gather dirt and dust for so long that any other technique would fall well short of the mark. There is a pretty good chance that you don’t know this, so let us be the first to tell you that this cleaning technique creates a lot of runoff that would be highly dangerous if it is allowed to contaminate drinking water supplies that are under the ground.
Hence, when you do some roof washing houston with pressure jets, you should consider using a reverse osmosis system to collect the water. This is because of the fact that this RO system will purify the water and remove all of its toxic components, and the truth of the situation is that this allows you to dispose of the water wherever you prefer without having to worry about any potential environmental disasters that it could create. However, the impurities that the RO method removes from the water need to go somewhere, so you might notice some grey sludge at the bottom of the machine once you remove the water.
This sludge is the aggregate impurities that you were trying to prevent from reaching groundwater aquifers and reservoirs, so it might not be a good idea to throw it in your garden. The fact of the matter is that this waste needs to be disposed of appropriately, and flushing it down the toilet would be a far safer disposal method for the most part. Whatever you do, don’t take it anywhere near drinking water otherwise it will get contaminated before you get a chance to mitigate.
