Climate change has gotten so bad that we already starting to see unusual and disastrous weather events occurring on a more or less regular basis, and this is often leading to situations where previously mild rain spells are turning into destructive storm fronts in some way, shape or form. A lot of cities that are a bit too low in their geographical terrain get flooded during the rainy season, and it is usually quite necessary for them to figure out how to drain the flood water at any given point in time.
A big part of the reason why that is the case has to do with the fact that allowing flooded areas to stay exactly how they are can result in widespread infrastructure decay, so finding a solution to remove this water from the affected areas is definitely something that is becoming a rather high priority for governments all around the world. One thing that these governments can use is a Houston power washing machine. It might surprise you to hear this, but on a fundamental level a pressure washer is basically just a machine that pumps water from a source and emits it with a lot of force and intensity.
Placing the feeder pipe of your rig into the flood stricken area will slowly but surely make the water levels decline. At eight gallons a minute it would take a while before the flood is gone entirely, but using a pressure washer can at the very least help you to make a reasonable amount of headway. At its core, the pressure pump in your rig can be used for any purpose including flood remediation all in all.
