Floodwaters recede and wastewater backups diminish; customer assistance needed

City requests customer help to identify localized backups as crews continue to respond  


After extensive efforts, the City of Boulder Utilities Division has restored the ability of primary sanitary sewer pipelines to deliver wastewater from neighborhoods to the Wastewater Treatment Facility on 75th Street.

Sewage back-ups have slowed as flood water rececedes

These efforts, combined with receding floodwaters, should allow pipes serving neighborhoods to drain and relieve backups into homes and businesses.  Flows reaching the wastewater treatment facility have decreased, from an excess of 50 million gallons per day (following the flood event) to 31 million gallons this morning.

 

While flows still remain at approximately two times the normal rate for this time of year, the change reflects a significant decrease in the amount of groundwater and floodwater entering the wastewater collection system and has allowed crews to access key pipelines to remove dirt and debris.

 

Given the extent of major flooding, it is likely that numerous blockages and damaged pipes impacting smaller areas remain.  In order to allow those issues to be addressed more efficiently, the city is requesting that residents and businesses who are still experiencing backups contact the Public Works Call Center at 303-413-7100 as soon as possible.   Updated information from customers will help crews more quickly locate and resolve issues in the city’s more than 355 miles of pipe and approximately 9,200 manholes.

 

The Public Works Call Center is open Monday through Friday, from 7 a.m. to 7 p.m.  If the public need remains, the city will extend call center hours over the weekend to be open from 9 a.m. to 4 p.m. on Saturday and Sunday.
