This does not necessarily indicate a problem with your septic tank. If the odor is near the house, it is probably coming from the vent stack on the roof. You will probably notice this odor primarily in the morning or late afternoon when the air is cooler. You may also notice this odor if there is no wind and the air is stagnant or if it is windy and the odor from a close neighbors vent stack has been blown into the yard. Excessive amounts of water being used all at once can push air up thru the vent and occasionally cause odor as well.

If it becomes a nuisance, there is the option of purchasing a charcoal vent filter. We do sell them, and it is up to the customer to install them.
