High on the list of experiences nobody wants to have is a sewer backup or overflow. Fortunately, that "yucky" experience usually can be avoided by being aware of what causes backups and avoiding those causes. The two primary causes of sewer backups and overflows are grease and roots.
Grease is the most frequent cause of sewer problems. If cooking grease or oil is poured down the drain or flushed down toilets, even when followed by hot water, it eventually cools down, congeals, builds up, and hardens, eventually forming a plug in both the home and the city sewer lines. Over time this situation will create backups and overflows. This unfortunate situation can be avoided if you allow the grease or cooking oil to cool, then dispose of it with the garbage. When the Water Services Department has to contend with sewer backups and overflows in the city sewer lines, there are consequences of both a financial and regulatory nature. So please, Cease the Grease, and help the city keep its sewers free from backups and overflows.
Plant roots are another frequent cause of sewer backups and overflows. The roots of shrubs and trees naturally seek any water source. The roots probe the sewer line seeking any opening, such as a crack or a poorly sealed joint. Once the sewer line is penetrated, the roots form a ball and block the line. The best way to avoid root blockages is not to plant trees and shrubs close to your home's clean outs or sewer service line. However, if trees or shrubs already are growing near the line, watch for reductions in flows down the drain. If a reduction in flow occurs, have a plumber check the line and clear the blockage if necessary.
It is important to note that home or property owners are responsible for cleaning and maintaining the sewer line that runs from the house to the connection with the city sewer main in the street or alley. The city, under City Code Section 28-5, will ONLY repair broken service lines within the public right of way. Please help us keep our sewer lines free of roots.
