Which of the following is NOT a requirement for concrete wash water?

The statement regarding the requirement that a container for concrete wash water must overflow regularly is not accurate. Proper management of concrete wash water is essential to prevent environmental contamination, and allowing a container to overflow can lead to spills and pollution of surrounding areas.

Instead, containers for concrete wash water should be leak-proof to securely hold the waste without risk of leakage. Additionally, hardened concrete waste must be properly removed to ensure that it does not contaminate the wash water and that disposal procedures are adhered to for liquid concrete waste. Each of these practices contributes to effective stormwater management by minimizing the potential negative impacts of concrete wash operations on water quality and the environment.
