Successful Sewer Rehabilitation Project
In 1997, the City of Cordova contracted with The Cassady Company to upgrade their wastewater treatment facility.

After a careful review of Cordova’s wastewater treatment plant and sewage collection system, it was decided that in lieu of upgrading the treatment plant, the infiltration, inflow, and exfiltration should first be handled in the collection system. To accomplish this goal, a three phase project was prepared to rehabilitate three areas of the existing collection system.

The City of Cordova sought grant monies through the Alabama Department of Economic and Community Affairs (ADECA) and a project of approximately $650,000 was prepared.

The first step of the project was to clean and video portions of the sewer system. The video revealed that the system was constructed mainly of vitrified clay pipe with joints every four to six feet.

In the Cordova area, there has been a lot of subsurface mining and settlement around the City. This activity was evident in the sags, cracks, and breaks in the sewer line joints. After a thorough review of the video, the following rehabilitation methods were considered: Insituform, pipe bursting, slip lining, and complete replacement. Due to the shallow depth, location of pipe, and quantity of pipe, the cost to rehabilitate this line favored the complete replacement of sewer line, manholes, and laterals
within the right-of-way.

The project was successfully completed cutting out approximately 50,000 gallons per day of infiltration and inflow.

Plans are in the works for Phases II and III of this project.

The approach by the City to put off enlarging the treatment plant will buy them additional time because of the capacity gained from ending the inflow and infiltration of the system. This project, constructed and completed within the time schedule and budget, was considered very successful by the City of Cordova.

Cassady’s Comments
Since we last published our newsletter, we have made a few changes. Most importantly, we have added new personnel. Many of our clients have had the opportunity to meet our new engineer, Angela Jones, and our draftsman, Brian Green.
