Water quality is essential for being healthy in urban areas. However, underground pipes in drinking water distribution systems have been licking significantly which increases pathogen intrusion into drinking water supplies from sources to consumers’ taps. Innonet presents antimicrobial pipes for improving drinking water quality delivered to consumers permanently and continuously, by incorporating antimicrobial biopolymer into the inner layer of pipes. Further tests prove a 99% reduction in air-borne pathogens in antimicrobial pipes in 24-hour contact time.
