GERMANTOWN, Tenn. (AP) - Army engineers have completed a $1.4 million project designed to protect a vital storm sewer channel that runs into a Mississippi River tributary in Tennessee.

The U.S. Army Corps of Engineers said Tuesday that it turned over the project in late March to the city of Germantown, a Memphis suburb. Engineers shored up Lateral D, a channel that runs into the Wolf River in east Shelby County.

Erosion of Lateral D was endangering an important sewage line that runs under it. A channel collapse could send millions of gallons of raw sewage into the Wolf, which runs into the Mississippi in Memphis.

Lateral D runs along woods, businesses and homes in the affluent suburb. Workers installed concrete pads, sheet pile walls and baffle blocks to fight erosion caused by rain.
