Wow , I will have to stakeout mine and see what they are doing in Maryland.
If pressure washing was more regulated, they would have reclaim, I spoke with the guys pumping the grease traps the other day in my area, and the county is on Sam's club once a month testing. That vacuum they use have some serious lift. They clean the grease trap every 6 weeks and the crud crust was at least 18" the technician said, but Sam's Club would not do it more often.
