Q:Chloramine Public Notice March 7, 2007
For many years, public water systems have added Chloramines to drinking water as a primary or secondary disinfectant. This is because of concerns of formation of disinfection by-product as the result of using free chlorine. The City of Shawnee is conducting a pilot study to evaluate the viability of using Chloramines as post oxidant...

Q:Do I need to buy a water softener?
Some companies sell ''water softeners'' to reduce the hardness of the water. The softener's purpose is to improve the aesthetics or ''feel'' of the water. Hard water contains high concentration of calcium compounds. The calcium in the water can deposit on faucets and shower curtains as a heavy white residue (which is most easily cleaned with a rag soaked in vinegar). Shawnee's drinking water hardness fluctuates throughout the year between 75 to 100 parts per million or 4.3 to 6.0 grains per gallon (one grain per gallon equals 17.24 parts per million). Water is considered ''hard water'' above 250 parts per million. Therefore, residents on Shawnee's water supply have soft water, and do not need a softener. By the way, even hard water is fine to use and drink without a softener.

Q:How do I know that my water is safe to drink?
Shawnee Water Treatment Plant has trained laboratory technicians and uses the service of the ODEQ Environmental Services Laboratory to analyze the quality of the water. Personnel from the lab monitor water quality at the water plant and at homes and businesses around the city to make sure that the water is safe to drink. Sampling and analysis is done continually throughout the year to make certain that the water meets or exceeds all E.P.A. and ODEQ quality standards

Q:If chloramines are harmful to fish, how can people safely drink the water?
Chloraminated water is no different than chlorinated water for all of the normal uses we have for water. Water that contains chloramines is totally safe to drink. The digestive process neutralizes the chloramines before they reach the bloodstream. Even kidney patients can drink and bathe in chloraminated water.

Q:What about the 2012 Yield Study?
In 2011-2012 the City of Shawnee (City) contracted with CDM Smith to evaluate its three municipal water supply reservoirs: Twin Lakes #1 and #2 (collectively called Twin Lakes) and Wes Watkins Reservoir. The primary purpose of this project is to establish the expected water supply capacity from each reservoir when operated individually and when operated as part of a complete water supply system. Other project tasks included evaluation of each reservoir's watershed and development of drought management plan. This report documents the methods and results of the hydrologic assessment and provides recommendations for future actions.

For the purpose of this study, firm yield is defined as the average daily withdrawal from a water supply system that can be sustained through the available record of inflows without entirely depleting the system storage. The available record of inflows (1953 to 2011) includes the drought of record which is defined as the period July 1954 to April 1957. This analysis was conducted in accordance with the guidelines established in the 2012 update to the Oklahoma Comprehensive Water Plan (OCWP). Hydrologic estimates of streamflow for both of the ungaged contributing watersheds within the system were generated using transposition by area ratio method and a dynamic simulation model was used to simulate the drawdown and recovery of the multiple reservoirs.

The firm yield estimates for the Twin Lakes (in this study, Twin Lake #1 and Twin Lake #2 were modeled as a single reservoir with two connected volumes as described in Section 6.1) and Wes Watkins are presented in Table 1‐1. The table lists the firm yield of the reservoirs operating individually, and also conjunctively, in the preferred operating mode of balancing water surface elevation and constraining withdrawals to permit allowances.

Q:What are Chloramines?
Chloramines, also known as combined chlorine, are a combination of chlorine and ammonia compounds which are used to kill potentially harmful bacteria in water.
Dated:10/30/2007 3:40:06 PM Back to Top--^
Q:What are the major benefits associated with chloramination?
Better disinfection in the remote areas of the water system, therefore making the water safer to drink. Chloramines greatly reduce objectionable taste and odor in the water. Chloramines have been found to be very effective at reducing levels of by-products that are normally formed with free chlorine.

Q:What is the metal content of the water?
Shawnee water is surprisingly low in dissolved metals. The lake water contains negligible amounts (much less than 100 parts per billion) of Silver, Arsenic, Barium, Beryllium, Cadmium, Chromium, Copper, Mercury, Nickel, Lead, Thallium, Selenium, and Antimony. Small amounts (less than 5 parts per million) of naturally occurring Aluminum, Iron, Manganese Sodium, and Zinc are also present in the lake water. The treatment process removes nearly all of these metals from the drinking water. The metals content in the drinking water is always in compliance with E.P.A. guidelines.

Q:What special precautions should fish owners take with chloraminated water?
Chloramines are toxic to fish, reptiles, turtles and amphibians, just as chlorine is toxic and must be removed. Chloramines can be removed from the water by using a water conditioner containing a dechlorinator or by using granular activated carbon.

Q:What special precautions should kidney dialysis patients take with chloraminated water?
Chlorine and chloramines must be removed from the water used in kidney dialysis machines. There are two methods to accomplish this, by adding ascorbic acid or by using granular activated carbon treatment. Medical centers that perform dialysis are responsible for purifying the water that enters the dialysis machines. Dialysis systems already pre-treat their source water to remove chlorine. However some modifications may be necessary to remove the chloramines.

Q:Where does my water come from?
All of Shawnee’s water comes from the Shawnee Twin Lakes and Wes Watkins Reservoir. It flows by gravity from the lakes to the water treatment plant where it undergoes aggressive treatment to remove all particulates and is chlorinated to destroy any pathogens. The water is then pumped to water towers around the city and it flows by gravity to your home. The water treatment plant can treat 8.7 million gallons per day to replenish water as it is used by residents, businesses and industries.

Q:Why are chloramines a problem for kidney dialysis patients and aquarium owners?
Chloramines are harmful when they go directly into the bloodstream. In the dialysis process, water comes in contact with the blood across a permeable membrane. Chloramines in dialysis water would be toxic, just as chlorine in dialysis water would be toxic. Fish also take chloramines directly into their bloodstreams.

Q:Why does my water sometime taste or smell like swimming pool water
Chlorine is added to the drinking water as a disinfectant (required by Federal Law). The amount added is only enough to ensure that the water at your house is free of bacteria and parasites. Usually, this amount is about 1 milligram of chlorine for each liter of water (1 part chlorine per million parts of water). A slight chlorine odor or no odor indicates that the chlorine is working properly as a disinfectant. Some customers buy sink filters to remove the chlorine for taste reasons. This is fine, but do not let the filtered water set too long since it no longer has its disinfecting abilities.

Q:Why does my water sometimes look brown?
Brown water occurs when normal sediments in the water lines become agitated. Agitation can occur when the lines are turned off for repairs or when a line breaks. The brown color is from iron (rust) particles that come off the pipes with age. Although it is undesirable, the water is safe to drink. The color can stain white clothes in the washing machine. Try to eliminate the brown color by running your cold water for 15 to 20 minutes (run from an outside faucet). If the color does not go away, contact line maintenance and they will send a worker out to flush the brown water out of the lines at a nearby fire hydrant.
Dated:5/6/2004 9:49:30 AM Back to Top--^
Q:Why does my water sometimes look ''milky'' or ''cloudy''?
Cloudy water is usually the result of dissolved air in the water lines. Air may be introduced into the lines as a result of line repairs or fire hydrant operations. This condition is usually temporary, although it may take several hours for the air to dissipate in the lines. To check if the cloudy water is due to dissolved air, fill a glass with water and leave it on a counter for a few minutes. The water should become clear again. Cloudy water of this type is safe to use.

Q:Will chloramines be removed by boiling the water?
No. Boiling is not an effective method of removing chloramines from water.
Dated:10/30/2007 3:43:53 PM Back to Top--^
Q:Will chloramines dissipate, or dissolve, out of the water?
No. Unlike chlorine, which dissipates when water sits for a few days, chloramines may take weeks to dissipate.
Dated:10/30/2007 3:43:39 PM Back to Top--^
Q:Will there be any noticeable changes with chloraminated water?
When the chloraminated water first flushes out the chlorinated water there may be a slight taste and odor, and possibly discoloration for a short period of time. This will not compromise the safety of the water. Try running your water taps for a few minutes to flush it out.

It is our goal to provide sufficient and safe water at the lowest possible cost to the citizens of Shawnee. 

   The City of Shawnee utilizes the Shawnee Twin Lakes and Wes Watkins Reservoir as its raw water source. They have an estimated combined storage of 34,000 acre feet with a surface area of 2,436 acres and dependable yield of 4.3 MGD. The Wes Watkins reservoir has increased the raw water available to the community.   Wes Watkins estimated storage is 11,581 acre feet of water at Normal (municipal) Pool elevations; at its flood pool elevation, the reservoir volume will be 21,869 acre feet and the surface area will be 1,640 acres. The Pottawatomie County Development Authority is the owner and developer of this project in partnership with the City of Shawnee. The dependable yield of the Wes Watkins reservoir is 4.5 MGD. Water from the three lakes will be used on a rotating basis to protect the water rights and provide for the needs of the City, PCDA and other users.

The City of Shawnee has four water storage towers with a total capacity of 2.5 million gallons.










The Wastewater Collection Division, with a staff of 7 maintains 135 miles of sewer mains, and ten lift stations. This includes repair and replacement of sewer mains, manholes, and video inspection of sewer mains. One crew spends eight hours every day jet cleaning sewer mains to keep them flowing properly. This division has flushed millions of feet of sewer line over the years.

The Water Treatment Plant produces an average 4.4 million gallons of potable water each day. The water treatment facility is located on south Kickapoo near the North Canadian River.  The first plant was originally built in 1895.

The Northside Wastewater Treatment Plant increased to 3.0 million gallons per day by a $3,500,000 project completed in June, 1997. The plant currently treats an average of 1.59 MGD of wastewater each day, much of which comes from the industrial area located in the northern area of Shawnee. As a part of the Northside Plant expansion a new interceptor line was installed from Wolverine Road and Harrison to the plant. That project eliminated a lift station and provided increased capacity to the industrial areas north of the plant. Improvements at the plant included two new clarifiers, increased sludge digestor capacity, a new chlorine basin and chemical building.

The Southside Wastewater Treatment Plant currently treats an average of 2.27 million gallons of wastewater each day. It has a capacity of 3.0 MGD. The Southside Treatment Plant serves the area south of the ridge line that divides the city. This includes the central business district and the major residential areas of the City. Both plants have excess capacity. The population equivalent of the treatment plants is 46,000.

The Industrial Pretreatment Program was approved by EPA in 1983 and revised in 1993. Objectives of the program include the following:  

    1. Prevent the introduction of pollutants into the POTW which will pass through or interfere with the treatment operations and/or the use or disposal of the municipal sludge;
    2. Improve the feasibility of recycling and reclaiming municipal and industrial wastewater and sludge;
    3. Enforce applicable Federal Categorical Standards and requirements; and
    4. Generally, to reduce the environmental and health risk, of pollutants discharged to the wastewater collection and treatment system.
