The City of Longmont has started its sewer rehabilitation program this week, targeting certain areas of the city to ensure the reliability and integrity of Longmont’s sewer system. This process will continue from now until December.
The city is targeting aging pipes to prevent future disruptions and protect the health of the public and the environment. These ongoing maintenance costs are covered through a portion of resident water rate fees.
There may be temporary lane closures while the city is completing the sewer infrastructure maintenance, but the City of Longmont will communicate with residents to prepare for potential disruptions. The city will attempt to reduce and minimize any closures that would prevent residents from accessing their homes and businesses.
Residents will receive a 24-hour notice before rehabilitation work begins in the area and this will typically occur between 8 a.m. and 5 p.m. Residents are asked to avoid using water during this time, including showering, laundry, dishwashing, and flushing the toilet. Backups can occur and may not be noticed until a day or two after the maintenance work is completed.
The city encourages residents to take proactive steps by checking P-traps in the floor, sink, shower, and bathtub drains. Make sure P-traps are filled with water as this will prevent odors from entering your home, especially during the rehabilitation work.
The American Society of Civil Engineers released a 2025 wastewater report card grading the nation’s sewer infrastructure. The nation received a grade of D+ for not spending the money needed to address aging infrastructure. Renewal and replacement rates decreased from three percent to two percent over the last decade and collection system failures increased from two to 3.3 per 100 miles of pipe. ASCE estimated a 70 percent shortfall of necessary funding for wastewater and stormwater infrastructure needs in 2024, emphasizing a need for communities to be proactive in rehabilitation and maintenance on sewer systems.
The city has a map that is regularly updated with the current work areas marked. Residents can contact Water Utilities at 303-651-8416 with any questions or visit the city’s sewer rehabilitation page for the latest updates.
