In a recent government meeting, officials addressed ongoing flooding issues in a triangular area between the Lincoln and Emmons pump stations and the River Drive Chamber. The discussion highlighted extensive testing and investigations conducted to identify the root causes of the flooding, which have been exacerbated by outdated infrastructure and improper documentation of the sewer system.
The area, originally designed as a combined sewer system, has faced significant challenges since regulatory changes in the 1980s. Officials revealed that they discovered multiple inflow points contributing to the flooding, including a bulkhead that was leaking approximately 500 gallons per minute into the system. Immediate corrective actions are scheduled, including the replacement of problematic infrastructure.
The meeting also underscored the aging condition of the RTB pump station, which is over 41 years old. Officials noted that the station's pumps are nearing the end of their life cycle, with operational issues such as floats failing to function correctly. This has led to delays in pump activation during heavy rain events, resulting in significant water accumulation in the wet well.
To mitigate these issues, the city plans to replace three of the six pumps at the RTB with more powerful models, aiming to enhance the system's efficiency. Additionally, a detailed analysis of the electrical systems at the RTB is underway to ensure they can support the new pumps.
Officials emphasized the importance of proactive management during rain events, stating that personnel will need to be present to manually activate pumps until the automation system is fully operational. A report detailing the findings and proposed solutions is expected by the end of October, with plans to utilize ARPA funds for necessary upgrades.
Residents have expressed frustration over persistent flooding, and officials reassured the community that measures are being taken to address their concerns. The city is committed to ensuring that citizens have dry basements and that flooding issues are resolved effectively.
