POTW is public owned treatment works. They are referring to the treatment facility that waste water goes to.
At the 'Bama RT I won a 5 gallon kit of PowerStroke. I had a nasty retaurant to clean and had lots of greasy 'crete. I used the PowerStroke as instructed and was really impressed. I made a 5 gallon bucket of solution and to get the 4 to 1 dilution I shot where needed with an Xjet. On less greasy spots probably would have done fine to downstream. They definitely made a customer out of me.
Both the greenness/safety of the alternatives (usually butyl based) and the hazzards of this main base can often be exagerated without an ounce of attention to concentration levels during real world use, dilution, or natural neutralizing. Being it hard to guess at how much strength is left after cleaning with it it would be best to neutralize either an acid or a base and not let it go down stream. What's detrimental or harmfull to the environment in case of NaOH is the salt left over is no good for freshwater aquatic life. It's not that it is crazy toxic.. heck it is used in food, household products galore, as a water ph adjuster,, you name it.
