The Big Bear City Community Services District Sewer Department has two Combination Cleaning/Vacuum Trucks in our fleet which are commonly referred to as Hydro's. These trucks are some of the most valuable pieces of equipment in the Sewer Dept. They are used every day for routine sewer line cleaning and are vital to breaking line stoppages. They are equipped with high pressure jetting hoses that clean our lines, clear roots, and break stoppages. These trucks also have powerful vacuums that can be used to suck up grit, grease, debris and overflows.
