The wastewater generated from washing out refuse bins and containers must adhere to which requirement?

The correct choice encompasses all the stated requirements regarding the wastewater generated from washing out refuse bins and containers.

First, the disposal of these wastewater streams must not negatively impact the environment or public health. Allowing the wastewater to run onto the surface of the ground can lead to contamination of the soil and waterways, creating unsanitary conditions and posing health risks. Adhering to regulations that prevent this scenario is crucial.

Second, passing the wastewater through a grease trap before it enters the sewerage system is essential when the wastewater contains oils or fatty substances. Grease traps are designed to capture these contaminants, preventing blockages and ensuring that the sewage system operates efficiently without becoming clogged or damaged.

Lastly, while the wastewater cannot simply be disposed of with regular garbage, this is an integral part of managing refuse-related wastewater responsibly. It highlights the need for proper treatment and disposal methods instead of contributing to waste streams that might not be managed adequately.

Thus, all these requirements work together to ensure the safe and responsible handling of wastewater from refuse bins, making the choice encompassing all options the right answer.
