Does Making Sure Storm Drains Are Clean Stop Sewer Backup? Storm drains may not be the first thing you think about when a sewer backup happens, but they should be. One question many homeowners ask is, does making sure storm drains are clean stop sewer backup? The short answer is yes, it can make a big difference. But there’s a bit more to the story. Let’s dig into how storm drains work, their connection to the sewer system, and what steps you can take to keep everything flowing smoothly—especially during heavy rains. What Are Storm Drains and How Do They Work? Storm drains are those metal grates you see along roads, sidewalks, and parking lots. They’re designed to catch rainwater and channel it away from streets and properties to prevent flooding. Do Storm Drains Connect to the Sewer System? In some areas, stormwater and sewage use the same pipes. This is called a combined sewer system. In newer neighborhoods, stormwater usually flows separately from sanitary sewage. However, both systems can be overwhelmed during intense storms. Where Does Storm Drain Water Go? Where does storm drain water go after entering those grates? It typically flows into nearby streams, rivers, or retention ponds—often untreated. Keeping storm drains clear of pollutants is crucial for local water quality. Can Stormwater Go to the Sewer? In combined systems, yes—stormwater and sewage travel together. During storms, the volume of water increases quickly, pushing both into the same network of pipes. If the system can’t handle the load, backups and overflows happen. Does Making Sure Storm Drains Are Clean Stop Sewer Backup? Let’s get to the heart of it—does making sure storm drains are clean stop sewer backup? Keeping them clear helps reduce pressure on the drainage system, preventing sewer issues. The Connection Between Blocked Storm Drains and Sewer Backups When storm drains are blocked with leaves, trash, or dirt, rainwater has nowhere to go. Water backs up into the street, and in combined sewer systems, it can reverse into basements and bathrooms. That’s when things get messy—literally. What Happens When Storm Drains Are Clogged? Flooding. Road damage. Basement leaks. And yes—sewer backups. Blockages slow down water flow and force it into unwanted places. Cleaning them out allows the system to do its job correctly. Can Storms Cause Sewer Backup? Absolutely. Heavy rain can overwhelm even the best-maintained systems. If storm drains are blocked, the sewer backup odds increase. It’s not just a rainy-day inconvenience—it’s a risk to your home’s safety. Why Do I Have Sewer Gas After Heavy Rain? That foul odor after a storm? It could mean your traps dried out or your sewer system got overloaded. Cracks or weak seals can also let gas sneak into your home. How Do You Prevent Sewer Backup in Heavy Rain? You can’t control the weather, but you can prepare your property. Here’s how: Keep Storm Drains Clean and Free of Debris This is step one. Cleaning storm drains may seem minor, but it plays a significant role in preventing backups. How Often Should Storm Drains Be Cleaned? Check and clear them monthly, especially before and after storms. Fall is an especially critical time with all the leaves falling. Install a Backwater Valve to Prevent Sewage from Flowing Backward This one-way valve stops sewage from backing into your home. It’s a wise investment for older homes and flood-prone areas. Maintain and Inspect Your Sewer Line Regularly Tree roots, grease, and sediment can build up over time. A camera inspection once a year can catch issues early. Avoid Pouring Grease and Non-Flushable Down the Drain Even if it looks like it goes down, it can harden and block your pipes later. Grade Your Lawn Away from the Foundation If your yard slopes toward your house, rainwater will follow it. Reshaping your lawn can direct water away instead. Seal Foundation Cracks and Basement Openings Water will find any tiny gap. Sealing cracks protects your basement from sewer and stormwater leaks. Use a Sump Pump with a Battery Backup System Sump pumps push water out of your basement. During storms, a battery backup keeps it running even if the power goes out. Disconnect Downspouts from the Sewer Line Make sure your roof runoff isn’t dumping directly into your sewer pipes. Redirect them into the yard or a rain barrel instead. Reduce Water Use During Heavy Rainstorms Flush less, delay laundry, skip the dishwasher. The less water you send into the system, the lower the chance of a backup. How to Clear a Storm Drain Here’s how to clear a storm drain safely and effectively without damaging the system: 1. Remove Surface Debris Using a Rake or Broom Sweep away leaves, trash, and sticks covering the grate. Clear a wide area around the drain. 2. Clear Leaves, Trash, and Sediment by Hand or With Tools Wear gloves. Use a small shovel or trowel to scoop out any gunk blocking water flow. 3. Avoid Using Chemicals or High-Pressure Hoses Harsh chemicals can harm local waterways. High-pressure water may push debris further into the system. 4. Check for Signs of Deeper Blockages The clog may be deeper if water still pools after clearing the surface. That’s a job for a professional. 5. Perform Routine Inspections to Prevent Future Clogs Make it part of your home maintenance checklist. Especially before the rainy season rolls in. What to Do When the Sewer Backs Up If the worst happens, don’t panic—but don’t wait. Stop Using Water in the Home Immediately Every flush, wash, or run of the faucet adds more pressure to an already stressed system. Protect Your Property from Further Damage Move valuables and furniture to higher ground. Place barriers in doorways if flooding begins. Ventilate the Area and Avoid Contact with Wastewater Open windows. Wear gloves and boots. Sewer water contains bacteria that can make you sick. Check If the Backup Is Local or Widespread Ask your neighbors or check online reports. If others are affected, the city may need to respond. Contact a
