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).
