What is an SSO valve?

An SSO valve, or Sewer System Overflow valve, is a safety device used in wastewater management systems to prevent overflow and potential contamination during heavy rainfall or system blockages. It automatically opens to redirect excess flow to a controlled discharge point, ensuring that the system operates within safe limits. This helps protect public health and the environment by minimizing the risk of untreated sewage entering water bodies. SSO valves are essential components in maintaining the integrity of sewer systems during extreme weather events.
