Spencer, IA (KICD) — Spencer Municipal Utilities says this week’s temperature fluctuations is causing the soil to move, and that has caused at least four water main breaks. Sheldon also dealt with a leak this week that created an outage for several blocks – we’re not sure what caused that one.

SMU says compromised pipes typically lead to a drinking water advisory for affected homes. They say customers are contacted by phone if the utilities has current information on hand, and they also post advisories on the doors in affected areas.
