I recently had a situation were I cleaned a large roof with no gutters and I caught as much SH runoff as I could in buckets. That worked quite well, however, I didn't know what to do with the solution in the buckets. This isn't covered in any of the modules. Can anyone help me out as to what to do with the runoff or lead me to education for proper disposal practices?
a sanitary sewer is usually okay, not a storm drain. Or you can use it to clean some concrete on jobs. if you put it in the ground, I would spread it out, away from trees, storm drains and let the dirt just naturally perk the solution away.
I like to reuse the collected chemical for cleaning the driveway and or decks. Use a push broom to move it around after you dump it out from place to place.
John's suggestion above is the correct way to dispose of unwanted run-off though.
