Sewer Line – The sewage smell you're experiencing could be a result of the sewer line being damaged. If this is the case and the leak is close enough to your home, the waste water would leak into the ground and make its way to the sump pit in your basement. Solution: This is best handled by professionals.Mar 22, 2019,
One of the most common causes of sewage smells is a clogged drain. When your home's wastewater has nowhere to go, the odors will come back up the drain they should be going down.Dec 21, 2020
Sewer odor comes from the breakdown of human waste and includes harmful gases like hydrogen sulfide and ammonia. Small doses of these gases won't harm you, but chronic exposure can be toxic.
Sewer smells from your yard: The sewer line runs under the front of your home, so if you begin to detect unpleasant odors of sewage rising from your front yard, it's a tell-tale sign of a broken sewer line. The yard will also become soggy, as if recently watered—just much, much smellier.
As the wind blows over the house, the air currents that are supposed to carry the gases up and away can instead carry the sewer gas down into the yard. Extending the vent pipe can help diffuse the odors, carrying them away from the yard. Carbon filters can also be placed on the top of the vent to help control odor.Mar 25, 2021
Blocked Drain FieldnnSometimes, either because of freezing temperatures or because a solid has caused a blockage, the drain field can become clogged, and the liquid cannot escape from the main tank properly. When this happens, the tank can fill up and overflow, causing the sewage odor to come up through the ground.
