Power Washing and Roof Cleaning Forum

When we did the Architecture building at UVA we had some difficulties meeting their strict new policies. If we cleaned with any chemical we had to capture 100% and dispose of in a sanitary sewer. If we used water only, we had to capture and then could dump it on the ground in any area where there was grass or gravel with no run off to sidewalks/driveways. We choose to use hot water to clean. Finding what we needed took some time, a wasted drive to Richmond and back to meet with a sediment control supplier who didn't have whet we needed.

I ended up using inflatable drain plugs and tractor trailer inner tubes and sand bags. There was a recessed drain system on a deck area we used the drain plugs, sucked out the dirty water to a tank, then opened the drain valve to discharge to a grassy area. In another place we used the inner tube to block the storm drain, another piece of inner tube covered an 8 inch piper from a grate to the garage. We pumped it out t as was collected to a grassy area.

These changes were sprung on us at the last minute. Due to time restraints we had to improvise and go the MacGyver route.  The whole capture and move thing was a PITA! Dirty water cannot go into storm sewers. Interesting!
