Following completion of a sewer cleaning job, which action must be performed at the manhole?

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

Answer: (C)

After a sewer cleaning job, controlling wash water and debris is essential to prevent pollution. The required step is to wash down the street around the work area and broom the wash water into the manhole so it enters the sanitary sewer system for treatment. This keeps contaminants from flowing into storm drains and the street, meeting environmental and safety requirements. Washing the truck or completing timesheets aren’t addressing the immediate need to manage runoff, so they aren’t the required action in this situation.
