Union City Electric

Ph: (731) 885-9212

Union City Electric serves the city of Union City and some of the surrounding areas.


The circuits serving our commercial areas have split circuits to provide a high level of reliability.

Rates are some of the lowest in the Tennessee Valley.


The system has the ability and capacity to serve most any requested load. Both industrial customers and industrial parks receive the benefit of substations adjacent to all industrial park locations. Some existing industries and future industries with adequate load levels could expect a dedicated distribution circuit for the ultimate in reliability.


The Tennessee Valley Authority serves the system with generation and transmission via a multi-line transmission system to a central point. The sub-transmission system is then taken from this point and provides loop service to the city, providing complete redundancy in case of equipment failure. The distribution system is very compact with short lines, greatly enhancing reliability. The system’s local, well-trained and experienced crews insure quick response and short outages. The management team stands ready to provide any new customers the highest degree of reliability at the lowest possible cost.


Water Supply

The City of Union City is fortunate to have an abundant supply of quality water from the Wilcox aquifer which is 600 feet in depth with a protected clay layer which is 50 feet in depth. The water plant’s treatment process consists of aeration, filtration, corrosion control, chlorination, and fluoridation. 406,350 gallons of treated water is stored at the plant clearwell.

The plant’s three high service pumps move the water from the clearwell into Union City’s 600 miles of distribution lines and five water tanks located throughout the service area. The water tanks have a combined capacity of 2,050 million gallons. This storage is used to meet system demands and fire flow requirements.

The Union City water system meets all state and federal regulatory requirements. Laboratory tests are performed daily to insure that the highest quality water is produced for the community.

Water Availability

The plant is an iron removal plant that is fed with four deep ground wells. Pumping on average 4 MGD of water, with a design capacity of 10.2 MGD, with five overhead water towers ranging from 250,000– 500,000 gallons. A new tank will be erected in the industrial park and will have a 500,000 gallon capacity.

The chemical makeup of our finished water is as follows:

  • Ph 7.0
  • Fe (iron) 0.0ppm with our raw water being 0.5ppm
  • Alkalinity 68ppm
  • Hardness 48ppm This is considered soft water
  • Fluoride 0.7ppm
  • CL2 1.6 ppm
  • Aquadene 0.3ppm This is a corrosion inhibitor for our distribution system
  • Powdered lime is used for ph adjustment.
  • Raw Water is aerated to remove any gasses such as H2S and will start the iron oxidation process
  • Treatment also consists of fed cl2 for disinfection.

The water plant is under constant monitoring to ensure un-interrupted supply to all industries and customers.
