Practical Solutions for Manhole Odor Control and Inflow Prevention

Municipal Department of Public Works (DPW) administrators and managers face ongoing challenges in maintaining sewer infrastructure, including odor control and stormwater inflow prevention. Industrial Odor Control offers specialized products designed to improve system performance, reduce maintenance costs, and address these common issues efficiently.

Activated Carbon Manhole Odor Filter Insert

Hydrogen sulfide (H₂S) and other sewer gases escaping from manholes create odor complaints and potential health risks for workers and the public. The Activated Carbon Manhole Odor Filter Insert helps mitigate this issue by using 20 pounds of Darco H₂S activated carbon, which absorbs and neutralizes odors. The design allows for easy carbon media replacement without removing the insert, reducing labor time. This passive system requires minimal maintenance, providing a cost-effective approach to long-term odor management.

Wolverine Brand Plastic Manhole Inflow Protector

Excessive stormwater entering the sewer system through manholes can lead to overloaded treatment plants, increased operating costs, and sanitary sewer overflows. The Wolverine Brand Plastic Manhole Inflow Protector prevents surface water from entering through the manhole cover, reducing the risk of inflow and infiltration. Made from high-density polyethylene, this insert is durable, lightweight, and resistant to corrosion. Installation is simple, and the factory-installed nylon strap allows for easy one-person removal during inspections or maintenance. By reducing inflow, DPW managers can extend the life of treatment infrastructure and lower overall wastewater processing costs.

Breakthrough Indicator Sticker for Hydrogen Sulfide

Odor control measures are only effective if properly monitored. The Breakthrough Indicator Sticker for Hydrogen Sulfide provides real-time detection of H₂S gas breakthrough. This colorimetric indicator changes appearance when the filter media is saturated, giving maintenance personnel a clear signal that replacement is needed. Designed for outdoor conditions, the sticker is unaffected by rain or runoff, ensuring accurate and reliable performance.

Custom-Fit Solutions for Municipal Systems

Manhole structures vary by municipality, making standardized solutions less effective. Industrial Odor Control provides custom-fitted manhole odor inserts and inflow protectors, manufactured based on specific measurements to ensure a proper seal and optimal performance. A detailed measurement sheet and order form help DPW staff collect accurate dimensions for ordering.

For DPW administrators and managers, reducing odors, limiting stormwater inflow, and maintaining infrastructure efficiency are ongoing priorities. The Activated Carbon Manhole Odor Filter Insert, Wolverine Brand Plastic Manhole Inflow Protector, and Breakthrough Indicator Sticker for Hydrogen Sulfide provide practical, durable solutions to these common challenges. By implementing these products, municipalities can improve sewer system performance while reducing maintenance costs and public complaints.
