The following case study is the third installment of a larger water resource research project. In the beginning of this project, questions were raised on which sector of water use would be examined. We chose to study the public supply, domestic, and commercial sector for a few reasons. Out of all the sectors of water use, public supply, domestic, and commercial and the irrigation and livestock sectors were the only ones to see increases in withdrawals (million gallons per day) from 1990 to 2010. In 1990 the irrigation and livestock sector accounted for 1% and accounted for 1.3% in 2010. This sector saw a 15% increase in water withdrawals over that twenty year period. In 1990 the public supply, domestic, and commercial sector accounted for 9% of all water withdrawals and 12% of all water withdrawals in 2010. This sector saw an 18% increase in total water withdrawals over that same twenty year period and had an increase of over 100 million gallons per day. Figure 1. (Sources: Solley et al., 1993 and Mauphin et al., 2014) Thus the public supply, domestic, and commercial sector has a much greater impact on Tennessee’s water use which is why this sector will be the subject of the study. Public supply water use is withdrawals made by private and public water suppliers who deliver it to customers who use the water for domestic, commercial, and industrial users as well as municipal water needs such as firefighting. Public supply water users can include water companies, private water companies, municipal water departments, regional water authorities, institutions, residential developments, mobile home parks, and homeowner associations (USGS, 2010). When a water use investigation occurs, each water system user supplies monthly data ... ... middle of paper ... ...asin transfer permits may also be needed in order to regulate distinct water withdrawals from surface water and aquifers that will not be returned. Water withdrawal registrations are needed before tapping a water source at “greater-than-threshold” amounts. This only asks that information be taken and filed to the appropriate agencies, no permits are required. Water wells are to be designed, built, and managed to the standards and rules of the state of Tennessee. Local requirements can vary in strictness depending on the county or municipality that you are in. Intake structure which are built for taking surface water from streams, rivers, or lakes, are going to require extra permitting for the work and design involved. They are currently taking measures in order to include more water supply planning and coordination, in a place of historically abundant water sources.
