Crossville City Council continues to look at water supplies versus demands estimated over the next 20 to 50 years as they work to make sure adequate water is available to communities on the plateau.
During the January work session, Greg Davenport, engineer for J. R. Wauford & Co. spoke to the council about the report they have been working on and talked about the next steps the council would want to consider.

reviews a list of recommended options with the
Crossville City Council during the February work session
Davenport pointed out that Crossville has been studying water supply needs for over 20 years and several reports have been presented with various recommendations and to date, only two projects have been done. The first is the pipeline between Lake Tansi and Meadow Park Lake for raw water and the second is the renovation of the 1938 dam at Meadow Park Lake.
In addition to studies, Davenport told the council that a large amount of modeling of Holiday Lake, Meadow Park Lake and Tansi have been done to determine maximum yields
According to Davenport, the estimated demand for water under moderate growth for 20 years is 8 to 9 million gallons per day (MGD) and for 50 years 11 to 12 MGD. Currently, the firm yield of the city's water reservoirs is 9.42 MDG. The maximum production capacity with the city's current water treatment plants is 7.5 MGD. In order to reach the maximum capacity, Davenport said likely the best plan for the city to increase the water treatment capacity would be by pumping raw water from Holiday Lake to Meadow Park Lake and expanding the Meadow Park Lake treatment plant.

Possible projects to meet future needs include raising the height of Meadow Park Dam to hold additional water from Holiday Lake, Lake Tansi and a possible water harvesting project from the Caney Fork River.
The city could expand the Holiday Lake water plant but it is 50 years old and could be more costly. Davenport said the firm could put together cost estimates for the various options and bring them back to the council at a future date.
