During a recent government meeting, officials discussed the limitations of the city's wastewater treatment plant, particularly its capacity to handle stormwater. The plant is designed to process an average of 6.5 million gallons per day, but the challenges of accommodating sudden surges in stormwater were highlighted. Officials explained that constructing a facility capable of managing four times the current capacity would incur astronomical capital and operational costs, making it impractical for the city.
The conversation also touched on the financial implications of stormwater management. Currently, only 15% of stormwater is required to be treated, yet the city is spending significant resources on treating the remaining 85%, which is not mandated. This inefficiency is exacerbated by the combined sewer system, which complicates the discharge of stormwater without mixing it with sanitary sewage.
Officials noted that during recent heavy rainfall, the plant received over 22 million gallons of water, far exceeding its normal intake. Such events disrupt the biological processes within the treatment plant, leading to compliance issues and potential fines. If the city fails to meet state-mandated capture rates, it risks receiving a consent order, which could result in fines ranging from $25,000 to over $1,000 per day for non-compliance.
The meeting underscored the urgency of addressing these challenges proactively. Officials emphasized the importance of securing grant funding to support necessary capital investments and avoid being placed on a state-imposed compliance schedule. The discussion concluded with a recognition of the complexities involved in modeling the city's combined sewer overflow (CSO) system, which lacks real-time monitoring data, making it difficult to predict and manage stormwater flows effectively.
