Can non-potable water sources be used in concrete mixtures?

Using non-potable water sources in concrete mixtures is generally not recommended because such water may contain contaminants, chemicals, or biological matter that can adversely affect the strength, setting time, and durability of the concrete. In the construction and civil engineering sectors, the quality of water used in concrete is crucial. The American Concrete Institute (ACI) and other standards typically stipulate that mixing water should be clean and free from harmful substances.

If non-potable water is used, there is an increased risk of poor performance of the concrete, which might lead to structural issues over time. Therefore, the most sound practice is to utilize only potable water or water that meets specific quality standards designated for concrete mixing, ensuring the integrity and longevity of the concrete structure.
