Extreme weather events and aging infrastructure are placing unprecedented strain on municipal budgets and sewer systems. For city leaders and financial officers, one of the most costly hidden challenges is rainwater infiltration.
During severe weather, traditional manholes allow substantial volumes of rainwater to enter sanitary sewer systems. This excess water forces municipalities to expend significant energy pumping and treating water that didn’t need treatment in the first place. Furthermore, this system overload is a primary driver of Sanitary Sewer Overflows (SSOs).
The financial and environmental toll of these overflows is staggering:
- The U.S. Environmental Protection Agency (EPA) estimates that up to 75,000 SSOs occur annually across the United States.
- Treating massive, unnecessary volumes of water strains municipal budgets through increased operational expenses and energy use.
- Non-compliance with environmental regulations due to SSOs can lead to substantial regulatory fines, diverting crucial funds from other community projects.
A Fast, Cost-Effective Solution Fortunately, managing this excess inflow does not require years of disruptive roadway construction. The patented Sewer Sentry Inflow Reduction Technology (US Patent 8,851,781) offers a proven, rapid-deployment solution. By replacing vulnerable manhole covers with a system featuring sealed openings and valve-reduced inflow, cities can stop surface water from overwhelming their infrastructure.
The return on investment is immediate and measurable:
- Energy Savings: By heavily reducing excess rainwater volume, municipalities experience drastically shortened lift station pump run times. Monitored systems have seen a minimum 30% reduction in energy demands for water processing.
- Overflow Prevention: In Louisiana’s West Ouachita Sewer District, rainstorm-related SSOs plummeted from 40 per year down to just 1 after implementation.
- Frictionless Installation: The retrofit utilizes the existing manhole frame. A standard three-man crew can install an average of 20 units per daytaking as little as 15 minutes per unit with absolutely no roadway construction or complex permitting required.
Municipalities can no longer afford to treat rainwater. By upgrading vulnerable access points, cities can immediately lower their operational costs, protect their citizens, and safeguard their local environments.
