Houston Water meets the Texas Commission on Environmental Quality’s drinking water requirements, including disinfection requirements designed to ensure safe drinking water free from contaminants, such as the amoeba naegleria fowleri.

Houston Water’s approved water treatment processes eliminate 99.9% of giardia and viruses, which ensures that other pathogenic organisms such as naegleria fowleri are also eliminated.
