LEWISTON, Minn. – A pressure problem with the Lewiston water system was resolved after a few hours, but people still were advised to boil water before using. Erik Fredberg, public works director, said in an update that the system was still being monitored to be sure it was operating as designed. The boil advisory would remain in effect until the state Health Department gives an OK. This, Fredberg said, was expected sometime Saturday. What caused the problem? Fredberg said a combination of factors led to what he called “a sensor/programming failure.” Contractors were brought on-site to identify, resolve, and re-test the system, he said.
