Boulder Drinking Water
(You can fill 5 gal bottles at El Dorado or Indian Peaks...with El Dorado evacuation, might be easier to get to Indian Peaks on N Broadway across from YellowPine Rd or where N Bld Spruce Cafe is located....across Broadway from that...small funky little office on West side of Broadway, must go there first). Or whatever other way you can do to be safe. They recommend not using tap water for drinking, cooking, brushing teeth, at least.
Here is one example close to us, and doesn't mention other possible sewage pipe damage within network of all flooded urban areas:
City officials have confirmed that an approximate 300-foot breach is allowing untreated wastewater to discharge directly into Boulder Creek. There is no immediate threat to Boulder or Lafayette drinking water. Boulder’s drinking water is drawn from reservoirs upstream of the city; Lafayette has been drawing its drinking water from Baseline Reservoir and has not been drawing drinking water from Boulder Creek.
The City of Boulder has notified federal, state and local authorities and is working on a temporary bypass around the breach to restore wastewater flow to the treatment plant. Officials are advising residents to continue avoiding flood water, and residents are being asked to minimize discretionary indoor water use, such as washing laundry. Industrial users are being notified to minimize wastewater discharges until Boulder’s system repair is complete.
