The South Logan Water Association (SLWA) water system was originally constructed around 1971. In 1983, the Association expanded by its acquisition of the Russellville Water District No. 1. Farmers Home Administration (currently USDA-Rural Development) and the Community Development Block Grant program have provided funds to assist with system construction. The South Logan distribution system consists of approximately 260 miles of water line. The water system consists of 10”, 8”, 6”, 4” and 3” and smaller PVC lines. These lines also connect in four locations with the City of Adairville and two locations with the Todd County Water District. Up until going on line with LTRWC, South Logan also purchased water from the City of Russellville to serve several customers along the Newtown Road, north of Russellville. This area has since been transferred to the City of Russellville.
Prior to switching service with LTRWC, Adairville supplied water to the SLWA system at its normal operating pressure corresponding to the City’s tank overflow elevations of 744 feet. Several South Logan customers around the Adairville area were in the Adairville pressure zone. Approximately three miles north of Adairville, water was boosted to the higher pressure zone served by the Russellville tanks with a 325 gallon per minute pumping station located on US 431. A second, 100-gpm booster station was located at Mortimer for filling that particular elevated tank.
As of the end of March 2003, the South Logan Water Association began purchasing all of their treated water from the completed water system of the Logan Todd Regional Water Commission (LTRWC). The Commission’s water treatment facility is rated at 10 million gallons per day, and their distribution system consists of nearly 85 miles of pipeline and three storage tanks totaling 3,500,000 gallons in capacity. The 2009 average daily LTRWC usage within the South Logan system was approximately 390,000 gallons per day. The existing transmission and distribution lines generally radiate from Adairville, its former water supplier, and from the Association’s water storage tanks south of Russellville. The system is well laid out with many loops. However, there are some dead end and low-flow lines within the system that require frequent flushing.
Currently, the South Logan water system is comprised of over 260 miles of water distribution lines and operates from three water storage tanks with a total capacity of 736,000 gallons, serving approximately 1,659 customers in southern Logan County. The primary storage structure is a ground level tank, located just south of Russellville, and the tank has a total capacity of 436,000 gallons and an overflow elevation of 842 feet. The other tanks are elevated storage tanks, located in the Mortimer and Schochoh communities. The Mortimer tank is a leg-style water storage tank, and it has a capacity of 100,000 gallons and an overflow elevation of 746,000 feet. The Schochoh tank is also a leg-style water storage tank, and it has a capacity of 200,000 gallons and an overflow elevation of 800 feet. The Logan Todd Regional system initially supplies water to the SLWA system in two locations. The larger feed point is located at the base of the Association’s ground level tanks in Russellville, and the other is located north of Adairville near the Red River along US Highway 431 to serve the Mortimer tank. A small pump station is utilized within the system to serve and fill the Schochoh tank. Flow through each of these metering points and pump station is controlled by the LTRWC SCADA system, and pressure is regulated as flow enters to match the existing tank overflows. System pressures are normally maintained by the level in the respective storage tanks.
Prior projects:
1993 RD Project: This project financed the construction of the Mortimer Tank and several waterline extensions in areas not serviced (Keysburg in particular).
1998 RD Project: Included construction of a 436,000 gallon ground storage tank in Russellville plus ~100,000 LF of waterline extensions to serve new customers and improve hydraulic conditions. Press Release info at the time: “The South Logan Water Association has started work on a $612,000 expansion of its system to provide water to more residents of southern Logan County. The project includes line extensions totaling over 17 miles and a new water storage tank. Garrison & Mitchum Construction of Greensburg, Kentucky is the contractor on the pipeline work, and Kentucky Glass Lined Tanks of Russellville will be constructing the tank. The project engineer is McGhee Engineering of Guthrie. In addition to providing water service to approximately 50 families, the project also helps enhance service to current customers. The new storage tank will furnish much needed reserve capacity to help provide continuous water service during an emergency. The project also includes new lines to areas of the sytem that occasionally experience low pressures.”
2003 RD Project: Included construction of a 200,000 gallon elevated storage tank in Schochoh plus ~110,000 LF of waterline extensions or replacements to serve a few new customers but mostly improve hydraulic performance. Project Narrative, at the time, included: “The proposed project involves construction of nearly 19.4 miles of water line on eleven rural roadways. Some of these lines are being planned primarily to serve new customers in need of a safe supply of drinking water, while others are being built to improve hydraulic performance of the existing distribution system. The Schochoh area of southwestern Logan County experiences low pressure during high demand periods. Also, since the Association has gone online with the Commission, residents east of Adairville have experienced a drop in pressure because they are now being fed through undersized lines rather than directly off the nearby Adairville system. This problem will be corrected by the construction of a new 200,000-gallon elevated water tank. Other low-pressure areas will be assisted by building interconnecting lines to complete hydraulic circuits or “loops”. The loops will also improve the water quality by cutting down on the stagnant water in dead-end lines. Also included in the project are the placement of master meter stations and an up-to-date telemetry system to allow for the monitoring and control of the system in greater detail. The total estimated cost of the proposed project is $1,650,000.”
Of course, South Logan Wter Association has undertaken several smaller projects since 2003. Any projects, regardless of size, help to improve our sytem and the quality of service to our customers.
