With the completion of a sewer cleaning job, which must be done at the manhole?

• A. Complete and sign timesheets
• B. Wash down the truck
• C. Wash down street around work area, making sure the wash water is broomed into the M.H.
• D. None of the above

Answer: (C)

Controlling wash water at the work site is essential to prevent environmental contamination. The required action at the manhole is to wash down the street around the work area and direct the wash water into the manhole so it can be collected and treated within the sewer system. This keeps runoff from entering streets or storm drains. While administrative tasks like signing timesheets or washing the truck may be part of daily duties, they do not address how wash water is handled at the manhole itself.
