What is Sanitary Sewer Overflow (SSO)

Sanitary sewer overflow (SSO) occurs when untreated sewage is discharged from a sanitary sewer system before reaching a treatment facility. This can happen through sewer line blockages, system malfunctions, excessive inflow and infiltration, or hydraulic overload during heavy rainfall events.


What Are Some Causes of Sanitary Sewer Overflow (SSO)

SSO can be caused by various factors, including grease and debris buildup in sewer lines, root intrusion, structural defects in pipes, improper sewer design or maintenance, and aging infrastructure. In addition, heavy rainfall or snowmelt can overwhelm sewer systems, leading to hydraulic overload and subsequent overflows.


Impacts of Sanitary Sewer Overflow SSO

The impacts of SSO are far-reaching and can have serious consequences for public health, the environment, and infrastructure. Untreated sewage contains pathogens, bacteria, and pollutants that can contaminate water bodies, posing risks to human health and aquatic life.


Sanitary Sewer Overflow can also cause property damage, basement flooding, and erosion, leading to costly repairs and cleanup efforts.


How Can You Prevent Sanitary Sewer Overflow

Preventing SSO requires a multi-faceted approach that addresses both structural and operational factors. This includes regular inspection and maintenance of sewer infrastructure, proactive measures to remove fats, oils, and grease (FOG), and debris from sewer lines, implementation of sewer separation projects to reduce inflow and infiltration, and investment in infrastructure upgrades to increase capacity and resilience.


Environmental Concerns of Sanitary Sewer Overflow

SSO poses significant environmental concerns, including water pollution, habitat degradation, and ecosystem disruption. Untreated sewage contains high levels of nutrients, pathogens, and contaminants that can degrade water quality, harm aquatic ecosystems, and jeopardize human health. Moreover, sanitary sewer overflow can contribute to algal blooms, fish kills, and beach closures, impacting recreational activities and tourism.


Financial Implications of SSO for Municipalities

The financial implications of SSO for municipalities are substantial and can include costs associated with emergency response, cleanup and remediation, infrastructure repairs, regulatory fines and penalties, litigation, and damage to public health and property. In addition, sanitary sewer overflow can result in lost revenue for wastewater treatment facilities and increased insurance premiums for municipalities.
