Dayton, Ohio – As the Lenten season brings an increase in traditional meals such as fish fries and seafood dinners, officials in Montgomery County are reminding residents and businesses to properly dispose of cooking grease in order to protect the local sewer system.
County leaders say the seasonal rise in frying and cooking with oils can lead to a significant increase in grease entering household drains. When grease is poured down sinks or toilets, it can create serious problems inside underground pipes and wastewater systems.
Officials warn that even small amounts of grease can cause major issues if it is not handled properly.
County Officials Warn of Sewer Problems During Lent
According to Montgomery County Environmental Services (MCES), grease from cooking oils and fats can harden once it enters sewer pipes. Over time, the hardened material can stick to pipe walls and build up layer after layer, eventually creating large blockages.
These blockages can lead to costly clogs, sewer backups, and potential system failures. When grease accumulates in the system, it can slow down or completely stop the flow of wastewater, creating a risk of sewage backing up into homes, streets, or nearby waterways.
Officials say the buildup also puts pressure on sewer infrastructure and water reclamation facilities that are responsible for treating wastewater.
In severe situations, large grease deposits can disrupt operations at treatment plants and increase the cost of maintaining the systems that keep water safe for the community.
Montgomery County leaders are encouraging residents to be especially mindful during Lent, when many families prepare meals that involve frying fish or seafood.
“Grease may seem harmless when it’s poured down the drain, but it can quickly cause issues,” said Commission President Carolyn Rice. “Taking a few extra minutes to dispose of grease properly helps protect our sewer system and prevents costly problems for residents and the county.”
Simple Steps to Dispose of Grease Safely
To help reduce the risk of sewer blockages, Montgomery County Environmental Services is urging both residents and restaurants to follow a few simple steps when dealing with leftover cooking grease.
Officials recommend that after cooking with oils or fats, people should first allow the grease to cool and solidify. Once the grease has cooled, it should be poured into a non-recyclable container, such as an empty milk carton, coffee can, or jar.
When the container becomes full, it can then be safely placed in the trash.
Authorities stress that grease should never be poured down the sink, toilet, or any household drain.
By following these simple practices, officials say residents and businesses can help prevent blockages, protect sewer systems, and reduce the risk of costly infrastructure problems.
County leaders emphasize that proper grease disposal not only protects pipes and treatment facilities but also helps maintain a cleaner and healthier environment for the entire community throughout the busy Lenten season.
