Situation:

Recognizing that rapid population growth in Cumberland County may lead to a shortfall of potable water, the Nashville District of the US Army Corps of Engineers selected GKY to estimate future water needs and evaluate strategies for ensuring an adequate supply.

Solution:

In the absence of zoning or other land use plans, GKY met with officials from the county and other municipalities to assess county-wide GIS parcel data and historical water sales information. We used this data to develop population, commercial and industrial projections for a 50-year timeframe.

We then used IWR-MAIN software, an industry standard, to project water demand and quantify the potential benefits of alternative water conservation programs. In a follow-up phase, GKY will evaluate the environmental, legal, economic, and yield implications of existing and potential water sources to recommend a robust, long-term plan for meeting the county’s growing water demand.
