Stop paying to treat rainwater.
Reduce inflow at the cover. Vent safely.
Different factors, including climate change, are placing increasing strain on sewer systems, leading to Combined Sewer Overflows, Sanitary Sewer Overflows, health risks, and infrastructure damage, resulting in costly long-term consequences.
Our technology provides solutions for both cities and homeowners, ensuring that excess water is kept out of the sewer system. For cities, this improves efficiency and reduces the risk of flooding, while for homeowners, it protects their infrastructure, saves on treatment costs, and helps safeguard the environment with Sewer Sentry.
Sewer Sentry replaces the standard manhole cover with a patented system that limits stormwater inflow into the sewer network while still allowing hydrogen sulfide gas to vent safely and helping protect infrastructure.
The Clever Cleanout acts as a relief valve on the main sewage line coming from your house, helping to prevent sewage backup into your home during blockages and heavy rainstorms while keeping the snakes and rodents out.
Sewer Sentry replaces the cover with a patented system that reduces inflow while still venting H₂S safely.

We’ve gathered answers to the most common questions we receive about Sewer Sentry. Click on any question below to explore more and discover how our solutions can help improve your wastewater system.
A sanitary sewer overflow (or SSO) occurs when the sewer system becomes overwhelmed by additional water. Normally, sanitary sewers are designed to handle wastewater from homes and businesses, but during rainstorms, extra water from rain can enter the system.
This extra water can come from manhole covers, open or broken cleanouts, and roof gutters tied to sewer service where rainwater gets into the sewer system. When the amount of water exceeds the capacity of the sewer system, it causes the sewage to overflow, leading to spills into the environment.
Rainstorms overwhelm sanitary sewer systems quickly due to the sudden surge in water entering the system. Normally, the system is designed to handle a steady flow of wastewater from homes and businesses.
However, during a rainstorm or storm surges from a hurricane, a large amount of water can enter the system at a much faster rate than the system can hold. This quick influx of water exceeds the system’s capacity, leading to overflows and spills onto beaches, waterways, and on the streets.
The Sewer Sentry System is a patented, engineered solution that replaces standard manhole rings and covers with specially designed components that block rainwater inflow and help prevent sewage overflows. By stopping excess water at the source, the system reduces strain on sewer infrastructure and lowers the risk of backups and flooding.
The Sewer Sentry System is built for long-term durability. It has been rigorously compression tested in accordance with ASTM D4280-12 standards and can withstand 6,000 pounds of load in multiple directions without cracking or deforming. This ensures reliable performance under real-world traffic and infrastructure conditions.
The System dramatically reduces inflow during rainstorms, lowering the sewer system’s exposure to corrosive gases. This efficient management of sewage overflow eliminates unnecessary costs at the pump stations and reduces environmental pollution caused by untreated sewage.
Yes, the Sewer Sentry Riser is designed to allow harmful gases to vent, making it safe. If the water level rises, a ball check valve prevents the rainwater from entering the manhole.
The Sewer Sentry System is available in sizes of 24 Inch, 26 Inch, and 32 Inch, with heights of 4 Inch and 7 Inch.
Sewer Sentry prevents excess stormwater from entering sewer systems, reducing the likelihood of overflows during heavy rain events. By stopping inflow at the source, the system lowers the release of harmful gases and untreated wastewater that can occur when infrastructure is overwhelmed.
As extreme weather events become more frequent, wastewater infrastructure must adapt. Sewer Sentry strengthens system resilience by limiting inflow during storms, helping municipalities reduce failure points, manage peak loads, and respond more effectively to climate-related stress on sewer networks.
By preventing rainwater, debris, and contaminants from entering the system, Sewer Sentry improves treatment efficiency and reduces unnecessary processing. This leads to lower energy use, reduced operational strain, and less waste generated across treatment facilities.
Sewer Sentry helps prevent sewage overflows that can contaminate rivers, wetlands, and coastal environments. By keeping wastewater contained and managed, the system supports the protection of freshwater resources, biodiversity, and sensitive ecosystems.
Inflow is a major contributor to sewer overflows and infrastructure failure, especially in aging systems. Addressing inflow at the source is one of the most effective ways to improve system performance, reduce environmental risk, and extend the life of existing infrastructure.
