You awaken one morning to find work crews and loud equipment outside your house. You learn that they are in the process of rehabilitating city sewer lines, something that has rarely, if ever, crossed your mind. Or maybe the problem is located down the street, and you’re not sure why workers with large and noisy vehicles are parked and blocking the street at your house.
The American Water Works Association has released its State of the Water Industry Report for 2014, which identified the top industry issues – infrastructure, long-term supply, financing for capital improvements and public understanding of the value of water resources, systems and services.
Wastewater collection systems are underground and out of sight. However, when a sewer rehabilitation project accounts for nearly one-third of a city’s wastewater system, it affects the community in a big way. LDA Engineering recently assisted Morristown Utilities Commission with the rehabilitation of the Spring Creek basin, much to the city’s benefit.
“We realize that you may never walk a mile in one of our nation’s heroes’ shoes, but you do have the opportunity to walk alongside them to honor what they’ve done.”
This is what I read about “Carry the Load,” a group of people walking from West Point, New York, to Dallas, Texas, to bring recognition to the true meaning of Memorial Day. I fell in with the group at a fire station in Chattanooga, was immediately handed a U.S. flag and jumped in line behind a group from the Chattanooga Fire Department, a veteran honored with the Purple Heart, several representatives from Abraham Baldwin Agricultural College and various other supporters.

Back when I was engaged in nonpoint source stormwater pollution research, the famous opening line of Bulwer-Lytton’s 19th century novel, “Paul Clifford,” invoked an image different than what the author intended. I imagined that it was raining and nobody was looking. But since then, all of that has changed. It’s still raining, but somebody is looking.

Chattanooga is a perfect place to appreciate all types of engineering. Described as the River City, Scenic City and Gig City, the Tennessee town owes its legacy to engineers.
Stroll across Market Street Bridge. Run down the Tennessee Riverwalk. Ride your bike around
VA’s Raccoon Mountain Reservoir or drive over Chickamauga Dam. These are only a few of the examples of the engineering feats that serve as the foundation for this City.he River City, Scenic City and Gig City, the Tennessee town owes its legacy to engineers.

Because infrastructure lies underneath the surface, most people only become aware of its necessity when something goes awry. However, a recent bill introduced in the U.S. House of Representatives intends to make it easier to fund much-needed water infrastructure projects.

A project with layers of perks that extend beyond the scope of the initial problem are more likely to be funded by cities. Other single-solution projects are increasingly being postponed or canceled entirely in favor of ones with multiple benefits to the city and its taxpayers.
Assessing the Capacity of a Small Community’s Sanitary Sewer System
In 2010, the U.S. Environmental Protection Agency (EPA) notified the City of Oak Ridge, Tennessee (City), that it must upgrade its sanitary sewer system to eliminate sewer overflows. The notice was a “tall order” indeed. The major components of the Administrative Order were to:
- Document previous sanitary sewer overflows;
- Prepare a sewer overflow response plan, or SORP;
- Implement a management, operations and maintenance program, or MOM;
- Complete a system evaluation and rehabilitation plan, or SERP; and (5) implement the rehabilitation plan.
