Under the Authority of the Tennessee Department of Environment and Conservation; (TDEC), T.C.A. 68-221-701 Rules of TDEC Division of Water Resources Chapter 0400-45-01-.17, the City of Millington is required to prepare and maintain an Emergency Operations Plan; (EOP), in order to safeguard the water supply and to alert the public of unsafe drinking water in the event of natural or man-made disasters. Emergency Operations Plans shall be consistent with guidelines established, reviewed, and approved by TDEC. The EOP shall include a Drought Management Plan; as part of the EOP. TDEC has granted the City of Millington Board of Mayor and Aldermen the authority to administer and enforce the guidelines set forth in this Drought Management Plan; RESTRICTED USE OF WATER-“in times of emergencies or in times of water shortage, the municipality reserves the right to restrict the purpose for which water may be used by a customer and the amount of water which a customer may use”. The City of Millington will recognize the Ground Water Quality Control Board (GWQCB) for Shelby County and will make decisions based on GWQCB supplemental information. Millington, Tennessee is a municipal corporation chartered and organized under the laws of the State of Tennessee. The City of Millington owns and operates 2 water treatment plants and 1 distribution system serving the citizens of Millington. The Mayor of Millington has the authority to implement a drought management plan and the Water Plant Manager has been given the responsibility to complete the plan. Purpose of the Drought Management Plan. Typically drought has not affected the Millington water source in past years. The purpose of this plan is to reduce water demand in the event of a drought where existing water supplies are inadequate to meet current demand for potable water. The significance of taking into account water use on average and during peak water demand (though it may not reflect an extreme or exceptional drought) is that system officials can identify water uses that have the potential to be reduced more readily and easier. The point here is to identify potential discretionary or non- essential water uses. Because water use data reflects a typical peak summer water use but not necessary a moderate, severe or extreme drought, additional water use could be expected by residential customers on the system to water lawns, wash cars, take extra showers, wash driveways, etc. For many years Millington has had a total of 7 connections with neighboring water systems. These connections would be available to reduce water demand and supplement available water supplies in the event of a drought when water supplies are inadequate to meet current demand. However since their sources are also groundwater, a drought that affects the City of Millington would likely affect them. 3 Drought Management Plan within the Context of an EOP. Development of Millington’s drought management plan and EOP were assigned to the Water Plant Manager. This person organized a team of individuals, including employees and local officials to help organize and frame the plan. Millington’s EOP addresses line breaks, power outages, contamination of water supply, and earthquakes. The EOP is not available for public scrutiny. The drought management plan focuses attention on managing supplies and demand during a declared drought. The Planning Committee. The Millington drought management plan is a separate component of the Emergency Operation Plan (EOP). It was developed by the Water Department staff of Millington, but included the local official team in its development and review. Unlike the EOP to which the drought plan is an “annex,” the drought plan includes a standby rate structure, restricts some water uses and in some cases bans other water uses at times. The drought management plan was approved by the Mayor and Board of Aldermen. The final approval process was the normal process used by the Mayor and Board of Aldermen to allow for public comment. The drought committee met on August 30, 2016. The Management Team consists of the City Manager, Mayor, Public Works Director, Safety Officer, Water Plant Manager, and the Water and Wastewater System Manager. These individuals work together discussing their thoughts in their areas of expertise to make highly educated decisions on when to implement the different phases of the drought situations. System Characteristics and Risks. The City of Millington obtains all water from 2 aquifers using a total of 6 wells. First is the Fort Pillow Aquifer which Millington operates 4 wells at a depth of 1,400 feet. 2 of these wells produce approximately 1,200 Gallons per Minute each and the other 2 of these wells produce approximately 900 Gallons per Minute each. Second is the Memphis Sand Aquifer which Millington operates 2 wells at a depth of 500 feet. 1 of these wells produce approximately 650 Gallons per Minute and the other well produces approximately 800 Gallons per Minute. The Memphis Sand Aquifer wells are used as stand-by wells while the Fort Pillow Aquifer wells are the main wells. The Millington Water System has approximately 3,158 water connections. Using the household factor of 2.60 persons per household for Shelby County this is equivalent to approximately 8,211 persons. The Millington Water Treatment Plants are conventional groundwater plants with a design capacity of approximately 3.15 million gallons per day. Average usage for the system is approximately 1,000,000 gallons per day. On August 13, 2007 there was a finished water flow amount of 1,664,000 gallons. Both water plants operated properly with no restrictions implemented on the system. The treatment plants use 6 wells as their raw water source. The treatment process consists of aeration, pre-chlorination, fluoridation, flash mixing, flocculation, coagulation, sedimentation, filtration, and post-chlorination. The distribution system contains 3 underground water storage tanks along with 1 elevated tank for a combined storage capacity of 2,300,000 gallons. These tanks in turn supply approximately 55 miles of various size water mains. The following information shows normal operation figures: 4 Month / Year Monthly Usage Average Daily Gallons Maximum Daily Gallons June 2015 27,755,000 925,167 1,155,000 July 2015 30,072,000 970,065 1,151,000 August 2015 29,786,000 960,839 1,128,000 September 2015 29,057,000 968,567 1,146,000 October 2015 30,558,000 985,742 1,659,000 November 2015 25,274,000 842,467 1,035,000 December 2015 24,846,000 801,484 886,000 January 2016 28,060,000 905,161 1,468,000 February 2016 24,130,000 832,068 1,335,000 March 2016 25,096,000 809,548 945,000 April 2016 25,263,000 842,100 1,301,000 May 2016 27,164,000 876,258 1,110,000 Goals, Objectives, and Priorities. The initial goal of the drought management plan was to provide water to all priority uses as established by the water system under worsening drought conditions (three levels). The water uses and levels of water availability take into account the maintenance of public health and safety, sustaining economic activity, preserving critical environmental resources and life activities. General Water Uses in Order of Priority: Hospital and medical facilities Nursing homes and elderly care facilities Human Consumption (Drinking water, domestic cooking, bathing, toilet use) Fire protection (structural facilities, and hazardous situations) Pets (animal hospitals, kennels) and livestock Environment (Erosion, Aquatic Habitat) Commercial Uses (Restaurant, Laundry, Office, Retail) Industry and Manufacturing (Sanitation, Process, Cooling) Recreation (Pools, Athletic Fields) Landscape (shrubbery) watering (Home and Commercial) Lawn watering, Vehicle Washing (Home and Commercial) Interconnections, Mutual Aid Agreements, and Backup Sources. All maps and drawings of the distribution system are located at the office of the Water/Wastewater System Manager. These maps and drawings contain the location of all known valves and water lines. The following is a list of the interconnection valve locations along with detailed drawings for Memphis Light Gas & Water and Naval Support Activity valves. Approval for use of water from these neighboring utilities must be made before opening the associated interconnection valve by contacting Memphis Light Gas & Water at 590-8016 or Naval Support Activity at 874-5792 Monday – Friday and 874-5744 during Nights, Weekends, and Holidays. 5 VALVE 1 Quito Road @ Shelby Road VALVE 2 VALVE 5 (Naval Support Activity) Cuba Millington Road @ VFW West Driveway Dakar @ Hornet VALVE 3 VALVE 6 (Naval Support Activity) Raleigh Millington Road @ Sykes Road Dakar @ Memphis VALVE 4 VALVE 7 Shipp Road East of Highway 51 North Crosspointe Church – South Of Driveway Ordinances, Policies and Legal Requirements.
