Wet Weather Concerns at Combined Sewer Wastewater Treatment Facilities

The treatment plants that serve combined sewer systems are readily impacted by storm factors. Wet weather impacts are not only due to the amount of rain or snow melt but also due to: the age and physical condition of the collection system; the level of groundwater around the sewer lines and manholes; the presence of footing drains and drainpipes from the roofs of structures leading into the sewer pipes; how the storm and sanitary sewers are joined together; the storage capacity in the collection system; the storage capacity of each unit of the treatment plant; and the plan put into operation to prevent hydraulic overloading in each step of the treatment process.

When the volume of sewage flow is greater than the capacity of the treatment plant, whether it be for combined sewers or sanitary sewers, it may be diverted into surface bodies of water which will contaminate these waters with physical, chemical, and biological agents leading to potential disease or injury to people, destruction of shellfish areas, lowered dissolved oxygen ratios, permanent or temporary closing of bathing beaches, and severe aesthetic concerns about floating debris, oil slicks, etc.
