Description:
No degree of treatment will insure the delivery of a safe water supplyto the consumer's tap when the distribution system is subject to cross-connections water pressure losses, frequent line breaks, open reservoirs and infrastructure deterioration. n one recent U.S. outbreak, water main break repairs did not include post,repair disinfection even though there was a substantial loss of water pressure over a few hours. n Lima, Peru, bacteriological data at the treatment works suggested plant effluent was excellent but as water proceeded out into the distribution system, water samples became increasingly contaminated with fecal coliforms possibly from blending ground water of questionable quality, numerous illegal connections to supply lines, water pipe leaks and daily losses in water pressure.
