New Director Announced

Columbia City Manager Tony Massey is pleased to announce his appointment of a new Wastewater Department Director. Mark Williams will officially step into his new position, with his promotion effective as of Monday, July 1st.

“I feel confident in appointing Mark Williams to this position,” said City Manager Massey. “He has demonstrated both a technical ability and enthusiasm that make him the best person for the job.”

Williams brings more than 28 years of experience, working in Columbia’s Wastewater Treatment Plant starting as an operator trainee in 1985, working his way up to Treatment Superintendent in 1992. Most recently, he has served as the Interim Wastewater Director following the retirement of Mike Anderson, who retired in April after 33 years of service with the City of Columbia.

In his new position, Williams will manage a large-scale professional services and construction contracts, oversee the wastewater utility, wastewater treatment, industrial pre-treatment, and sanitary sewer collection system. The Wastewater Department currently has a nearly $12 million annual budget and a staff of approximately 50 employees. Williams says, he has only become more interested in the field over his time working in the field and he is looking forward to both the challenges and opportunities of his new position.

Mark Williams is a native of Columbia and graduate of Central High School. In addition, Williams holds an Industrial Technology Certificate from Columbia State Community College, a Grade 4 State of Tennessee Operators certificate and will complete the necessary requirements for a Grade 2 Collections certificate in November.

What We Do
The Columbia Wastewater System consists of collection facilities and treatment facilities designed to transport and remove pollutants from the wastewater generated by users within the service area.

A Brief History
The Collection System is divided into basins and sub-basins. These basin boundaries are typically defined by the natural topography of the land. Pump stations are used only when wastewater must be transported to another basin. The Columbia Wastewater System currently operates 21 remote pump stations.

The Columbia Wastewater System operates a conventional activated sludge treatment facility. The facility went "on-line" in March of 1979 with a major upgrade in 2000. The Wastewater Treatment Plant has the design capacity to treat 14 million gallons of sewage each day. The facility is staffed 24 hours per day. Our operating employees must have State of Tennessee certification and license based on the conditions of our National Pollutant Discharge Elimination System Permit and the State of Tennessee regulations. Laboratory analysis must be performed daily for self-monitoring reports and for process control. Columbia Wastewater System is continually adapting to new rules and regulations issued from the State and the Federal Governments.

Funds to operate the wastewater system are generated by service fees charged to customers of the Columbia Wastewater System. City property taxes do not fund the wastewater system
