3.0 MAJOR COMPONENTS
The Paris water distribution system consists of an intake pumping facility, a water
treatment plant, a high service pumping facility, and transmission and distribution
systems. The treatment plant serves approximately 4874 retail customers and one
wholesale customer. The treated water transmission and distribution system consists of a
grid of mains ranging from 2 to 18 inches in diameter and has a total elevated storage of
2.45 million gallons (3 Tanks). The plant as of 2010 has an average use of 1.81 million
gallons per day and the plant’s total treatment capacity is 3.0 million gallons.
3.1 Distribution Piping
The City of Paris’ water distribution system is comprised of pipe sizes up to 18 inches in
diameter. The transmission mains from the water treatment plant consists of an 18 inch
line which splits off into two 10-inch lines and a 16-inch line. The two ten inch lines
extend into the center of the city. The 16 inch line runs directly to the 10th
street water
tank.
Figure 2. Schematic of Paris Water Distribution System
There are pipes of several different materials installed within the system. Table 1 displays
the material, the different size diameters and the total length of each material. The age of
the pipe material ranges depending on what section of the city you are in. Ages typically

range anywhere from 85 years old to less than 5 years old. There are ductile and cast iron
pipes that are 85+ years old. PVC pipes generally range from around 35 years old to less
than 10 years old. Asbestos cement pipes were all installed in 1976.
Table 1. Summary of Pipe Materials
3.2 Water Treatment Plant
3.2.1 Current Facilities and Operations
Paris’ water treatment plant draws water from Stoner Creek. Water is pumped into a
rapid mixer by raw water (low service) pumps. The water is pumped in at a rate of 2,100
gallons per minute. The flow rate is important in that all detention times throughout the
treatment process are based on this flow rate. Once the water has been pumped poly
aluminum chloride or alum, lime and sodium permanganate are added and thoroughly
mixed with the creek water. Dosages vary depending on the water conditions. Detention
time in this basin is one minute.
Water then flows into the coagulation basin where it is slowly mixed by two mechanical
paddles. As the water flows through, the chemicals reacting with the particulate matter
start to form what is known as floc particles. These particles continue to grow in size and
mass as they continue through this basin. Carbon is added when needed in this basin for
taste and odor control. Also sodium permanganate is reacting during this time to oxidize
any metals that may be dissolved in the water as well as oxidizing other organic materials
present. The detention time for this basin is forty minutes. Chlorine is added for
disinfection at the effluent of this basin.
The water then flows into the settling basins where the flow particles settle to the bottom.
The water then flows to the filters. The detention time in the settling basins is
approximately four hours.
There are four filters that are called dual media rapid sand filters. They utilize both sand
and anthracite as the filtering medium. The filters are equipped with rate of flow gauges
and controllers that maintain a constant and balance flow through each filter. The filters

retain any particles that may not have been removed in the settling basins. They filter at a
rate of two gallons per square foot per minute. Chemicals added in the filter effluent are
fluoride, ammonia and chlorine. Caustic soda is added to help control the pH.
When the water leaves the filters, it enters the clearwells were it is stored on site. The
treatment process is complete other than the contact time with the chlorine or
chloramines which are added after the filters. By the time the finished water reaches the
high service pumps, the chlorine contact time is complete and the water is then pumped
into the distribution system where it reaches the City of Paris customers.

3.2.2 Pumps
Paris Water Works has 5 pumps located at their water treatment plant and 1 booster pump
located off of their 19th
Street Water Storage tank. At the treatment plant there are 2 raw
water pumps, 2 high service pumps, and 1 wash water pump. Table 2 contains the
capacity, horsepower, and total head of each pump. Refer to Appendix A for pump curve
information for the 2 high service pumps and the booster pump.

3.2.3 Water Treatment Plant Discharges
The average daily demand in 2010 for the Water treatment plant was 1,810,000 gallons.
The maximum daily demand in 2010 was 2,870,000 gallons. Figure 4 and Figure 5
illustrate the average daily demand and maximum daily demands between September
2008 and May 2011.

3.3 Tanks
The City of Paris utilizes 3 storage tanks, Bypass, 19th
Street and 10th
Street Water Tanks.
These three tanks were constructed in 1985, 1950 and 1959 respectively. All tanks are
pressure tanks. Telemetry data is recorded via radio. Paris is currently working to
upgrade its telemetry system for its tanks. Table 3 shown below displays some general
characteristics of each tank.

3.4 Valves and Hydrants
The City of Paris currently has 465 valves installed within its system. The City of Paris
currently has 312 hydrants located across its distribution system. The City of Paris
typically performs fire flow tests on each hydrant every other year.
3.5 Water Quality Monitoring
Water Quality Monitoring— Samples are taken daily and tested in a lab to help ensure
the standards for water quality are met.
Continuous water quality testing is performed at the Paris Water Treatment Plant. Water
is tested for turbidity, alkalinity, hardness, iron, manganese, fluoride, pH, corrosiveness,
and disinfectant residual. Table 4 summarizes aspects of the 2010 Water Quality Report.
For the full water quality report refer to Appendix B. (City of Paris Combined Utilities,
2011)

In 2010 Paris Water works was in violation of its Chloramines levels, its Haloacetic
Acids levels, and its Total Organic Carbon levels.
“In August 2010 a team of Individuals from the U.S. Environmental Protection Agency
(USEPA) Technical Support Center (TSC) and the Kentucky Department of
Environmental Protection (KYDEP) conducted various studies to facilitate the
development of a chloramine distribution system optimization approach. The studies
included a review of selected historical water quality data, distribution system sampling,
kinetic studies, storage tank assessment, and evaluation of nitrification potential curves.
These studies began in August 2010 and concluded in January 2011.” (USEPA Technical
Support Center, 2010).
