Effective sewer gas mitigation is one of the most pressing challenges for modern utility managers and municipal engineers. Managing aging collection systems often feels like fighting a two-front war against corrosive, odorous sewer gases and surface water inflow. Traditionally, addressing these dual issues required complex, highly disruptive construction and entirely separate mitigation strategies.
Fortunately, managing your infrastructure no longer has to be a costly headache. At Sewer Sentry, we believe in working smarter. That’s why we’ve developed the Sewer Sentry® Retrofit Dual Solution—a single, highly innovative approach designed to stop surface inflow and handle sewer gas mitigation safely, all without the heavy costs of traditional rehabilitation.
The Urgent Need for Inflow Control and Sewer Gas Mitigation
When surface water enters your sanitary sewer system through vulnerable manhole covers, it leads to a cascade of expensive problems. This inflow eats up valuable wastewater treatment capacity, increases operational costs, and can ultimately lead to Sanitary Sewer Overflows (SSOs). According to the Environmental Protection Agency (EPA), SSOs pose serious environmental and public health risks, often resulting in hefty regulatory fines for municipalities.
At the exact same time, hydrogen sulfide (H2S) gas is building up within the system. Without proper sewer gas mitigation, this highly corrosive gas destroys concrete infrastructure from the inside out and creates severe odor complaints from the surrounding community.
1 Product. 2 Massive Benefits
The Sewer Sentry Retrofit is designed for ultimate efficiency, tackling both of these major infrastructural threats at once. Instead of tearing up the street to replace entire manhole assemblies, our unique system utilizes your existing frame.
By combining a specialized drop-in gasket with our proprietary new cover, you instantly upgrade your vulnerable structures. This creates a watertight seal against inflow while safely venting dangerous gases.
30-Minute Installation with Zero Roadway Disruption
Municipalities are rapidly adopting the Retrofit Dual Solution because of its seamless deployment:
- Rapid, 30-Minute Installation: Your utility crews can upgrade a manhole and move on to the next one in just half an hour, drastically reducing labor costs.
- No Roadway Disruption: Because we use the existing frame, there are no jackhammers, no heavy excavators, no repaving, and no frustrating traffic detours for your local businesses and residents.
- Stops Inflow instantly: Keep your valuable treatment capacity from being wasted on excess stormwater.
- Vents Gas Safely: Protect your concrete assets by allowing hazardous, corrosive H2S to escape naturally.
- Cost-Effective Scalability: Stretch your infrastructure budget further by avoiding full structural replacements.
Comprehensive Assessment Before You Spend
We know that a great product requires an excellent deployment strategy. That’s why Sewer Sentry is committed to being a dedicated partner in your infrastructure management. Before you spend valuable Capital Improvement Plan (CIP) dollars, we help you make data-driven decisions to prioritize your highest-risk structures for sewer gas mitigation.
Our comprehensive utility services include:
- System Analysis & Inflow Assessment: We help identify your most vulnerable structures where stormwater inflow is costing your utility the most money.
- H2S Logging Studies: We pinpoint high-corrosion and high-odor areas to protect your underground infrastructure and improve community relations.
- Surcharge and Storm Event Evaluation: Gain a deep understanding of how your collection system behaves under maximum stress during severe weather events.
- Targeted Pilot Installations: Try the Retrofit Dual Solution in your most problematic areas to prove the concept and measure the exact results before committing to a system-wide rollout.
