Rainstopper Field Notes
Insights on manhole inflow protection, product design, and real-world installations.
Five Real-World Uses for Manhole Inserts Beyond Inflow Protection
The “Swiss Army knife” analogy gets overused. But when a product consistently solves multiple real-world problems in the field, the comparison starts to make sense. Most municipalities first think about manhole inserts in terms of inflow and infiltration control. That...
Choosing the Right Manhole Insert Configuration for the Field Conditions
Most manhole inserts are ordered pretty routinely: standard stainless or HDPE, standard configuration, done. But conditions in the field are not always routine. Details like gasket selection, retention systems, handle style, and material choice can make a real...
Grease Trap Odors and Sewer Problems: Where Manhole Inserts Can Help
Restaurants, schools, and commercial kitchens rely on grease traps to help keep fats, oils, and grease (FOG) out of municipal sewer systems. When those systems are overloaded, poorly maintained, or servicing high-demand areas, the effects often show up beyond the...
Protecting Municipal Manholes During Construction
Why Sediment Control at the Structure Matters On active construction sites, sediment movement is expected. Mud tracks across pavement. Concrete splatter happens. Fine particles move with runoff. But when that material enters a municipal manhole or stormwater...
Case Study: Flood Mitigation, NY
The Challenge When Hurricane Sandy made landfall in 2012, New York City’s underground infrastructure was severely impacted. Treatment plants shut down. Underground utilities were flooded. Recovery extended for months. In the aftermath, the Metropolitan Transit...
Customization
In the real world, manholes rarely match the drawings perfectly. Frames are off by a fraction. Covers have been replaced over time. Drop rings show up where no one expected them. Field crews are left figuring out how to make a standard product work in a non-standard...
Made in USA
At Rainstopper, our manhole inserts have always been made in the United States, not as a marketing slogan, but as a standard. From sourcing materials to fabrication and assembly, every step of our process has remained 100% American-based since day one. That...
Patent Solutions
At Rainstopper, patents are not about protecting ideas for their own sake. They exist to solve problems that show up in the field, day after day, manhole after manhole. Over the years, we have developed and secured multiple U.S. patents related to manhole inflow...
