Fairfield Glade Community is updating their Wastewater treatment system. The community is full of multiple amenities including lakes and golf courses, and lies between Knoxville and Nashville, within the city limits of Crossville. Since development began in 1970, the community has been served by a private water district and a private wastewater treatment system fed by gravity and low-pressure sewers. The original treatment plant, about 7 miles from the southernmost point of the development, used an extended aeration process and discharged to a stream called Bagwell Branch. After approximately 25 years of use, that system had become obsolete and undersized. It was then replaced by the lagoon system with 2.9 mgd design capacity and 0.86 mgd average flow. When the functioning of older systems became inadequate, the city devised an alternate dispersal method and has integrated the use of drip dispersal system pumps. The technology was developed for large agricultural irrigation projects and has been widely used with wastewater applications such as small commercial and housing clusters. The community’s total 16,000 building sites include about 10,000 still available. About 100 new homes recently started construction in both, and building continues. That means growth ahead for the treatment plant and its drip irrigation system.
The city of Memphis is also planning significant rehabilitations to their sewer system. Staring this year, there will be a 4 year Capital Improvement Program (CIP), which is intended to be a multi-year plan for capital expenditures to replace and expand the City’s infrastructure, vehicles and equipment. For program purposes the City defines a capital improvement as a major improvement or acquisition costing over $50,000 that will last 10 years or more. The program is updated annually to reflect the latest priorities, updated cost estimates and available revenue sources.
