Sewer Lift Station Compliance

News and Updates.....

Interlocken Lift Station:  Council approved an agreement with Moltz Construction to be the Construction Manager/General Contractor for the station rehabilitation portion of the project at the October 12, 2021 meeting.  Moltz began site work in February while waiting for delivery of long lead items.  The overflow containment and site fencing were completed.  The remaining work was scheduled to begin in July however, due to material shortages and delays, the start date was postponed until September and then again delayed for a temporary power switch which needed to be completed by Xcel Energy.  Work started in earnest in December.  The contractor and staff are completing commissioning of the station.

Staff started with the Interlocken Lift Station due to its size (largest) and recent operations and maintenance issues including equipment and piping failures.  Council approved a consulting agreement on February 9, 2021 with Burns & McDonnell to complete the required Interlocken Lift Station Site Application and begin work on the design documents for the required renovation.  Work on the station was delayed due to equipment shortages. Interlocken LS Feb 2023

Background Information

The Colorado Department of Public Health and Environment (CDPHE) is the governing state agency for sewer lift stations within the state of Colorado.  Municipalities are required to receive approval from CDPHE to build and operate lift stations by submitting site applications for each station. Of the 13 existing lift stations Broomfield operates, there are four lift stations in which staff and CDPHE are unable to locate any existing/historic records or information on the site applications.  These four stations were designed and constructed in the 1980’s.  Since the written records for the site applications cannot be located, CDPHE has notified Broomfield of their noncompliance and is requiring Broomfield to become compliant.  Other municipalities who constructed sewer lift stations during the same timeframe are in similar circumstances and are being required to comply with CDPHE regulations.  In December 2017, Broomfield contracted with Burns & McDonnell Engineering Co., Inc. (B&M) to assist staff to work with CDPHE to determine if Broomfield would be required to submit Site Applications and what requirements would be necessary to bring the stations into compliance.  CDPHE held a series of meetings with stakeholders and reviewed information from municipalities, ultimately determining all sites would need to submit site applications and be compliant with current regulations in late 2019.
