In a recent government meeting, officials addressed the severe flooding that impacted the community on two occasions within a week, resulting in significant challenges for the local wastewater management system. The storms, which brought between four to five inches of rain in just one hour on both Wednesday and Saturday, overwhelmed the wastewater plant, which typically processes around 4 million gallons daily but peaked at 22.2 million gallons during the storms.
Officials noted that the flooding was exacerbated by stormwater infiltrating the sanitary sewer system, often due to improper connections from downspouts and footer drains. This influx of rainwater led to backups in residential basements, with many homeowners experiencing clear water flooding due to the capacity limits of the sewer pipes.
The meeting highlighted the urgent need for infrastructure improvements, including the installation of additional equalization basins and larger pipes to accommodate increased rainfall, which has become more frequent due to climate change. A comprehensive flow rate analysis and system study, authorized by the council, is set to be presented later this month, outlining recommendations for enhancing the system's capacity.
In response to the flooding, officials discussed a rebate program for homeowners and businesses installing check valves to prevent stormwater from entering the sewer system. The program offers up to $1,000 for proper installation, although many existing installations have been found to be ineffective due to improper placement.
Additionally, the council discussed waiving extra trash fees for residents affected by the flooding, allowing them to dispose of flood-damaged materials without incurring additional costs. A motion was made to implement this waiver until the end of July, with logistics for managing the increased waste still to be determined.
As the community grapples with the aftermath of these storms, officials emphasized the need for proactive measures to mitigate future flooding risks and improve the resilience of the wastewater management system.
