The Environmental Protection Agency (EPA) estimates there are at least 23,000 and 75,000 sanitary sewer overflow (SSO) events per year - not including sewage backups into buildings - in the United States. These SSOs are responsible for discharging between three and ten billion gallons of wastewater into our communities each year. The four critical points of infiltration causing these SSOs are:
- pipe joints
- lateral connections
Avanti injection grouts are designed to address each of these critical points of infiltration in structurally sound pipe.
