" Night is the best time to visit sewers, because the businesses dispelling the most waste are closed, and the flows are calmer. "
- Rose George

Rose George's observation about night-time sewer inspections highlights a practical consideration: during nighttime hours, businesses are typically closed, which means less waste is being flushed into the sewage system. Consequently, the flow within sewers becomes more manageable and predictable for inspection purposes.

Beyond its literal meaning, this quote also offers insights into urban infrastructure management and environmental awareness. The idea that night provides a clearer picture of sewer systems underscores the importance of understanding how city utilities function at their least active times. This perspective is crucial for engineers, planners, and policymakers who work to maintain and improve urban sanitation. Furthermore, it suggests that effective planning and maintenance often require looking beyond peak usage hours to grasp the full complexity of infrastructure needs.
