Sanitary Sewer

Smithfield City contracts with Logan City for Wastewater Treatment. Smithfield City Public Works are responsible for the operation and maintenance of the City's sewer collection system. This includes all the main sewer lines and manholes generally found in every city street. Properties are connected to the collection system through a pipe known as a sewer lateral. The sewer lateral runs from the end of the structure to the city main sewer pipe in the street.  Property owners are responsible for the maintenance and installation of the sewer lateral from the house or business to the connection into the main sewer line. The main sewer lines collect the sewage and transport it to the Wastewater Treatment Plant located in Logan City.  Once at the plant the sewage is biologically broken down into solids and clean water. To prevent backups and buildups, routine operation of the jet cleaning equipment is performed. This operation maintains the system by using high-pressure water along with mechanical cutters to remove roots, rocks, grease and other such buildup. The portable lateral camera also helps identify problem areas and evaluate maintenance operations.

If a backup occurs
First take action to protect people and valuable property. You may call the city and we’ll check the main sewer. Any blockages found in the main lines will be promptly cleared. If the main line is not blocked, we recommend that you call a plumbing or sewer contractor to check your sewer lateral line. Maintenance and repair of the lateral serving the home or business is the responsibility of property owner/occupant. Regardless of the location of the blockage. 

Back up Prevention
Taking notice of what is flushed down toilets and sinks can prevent most backups. DO NOT flush the following materials (or similar items) down toilets/drains. These items can plug the main and cause damage to you and other property owners connected to the main line. 
• Large quantities of toilet paper
• Paper towels
• Feminine napkins (plastic applicators)
