Yes, the water is safe. The substance you see is manganese, which is a natural precipitant of treated water and normally adheres to the sides and bottom of the water main. When the pressure and/or flow of the water changes the manganese can scour off the walls of the main and get into your home or business. Manganese is a natural mineral and is not harmful. Discolored water happens when a water main is bumped or moved, as in construction, or there is a change in the pressure and/or flow within the pipe, such as what happens when a fire hydrant is opened, a valve is operated or a main is broken.
Discolored water can be caused by many factors, i.e., construction in the area, lightening strikes, operation of a fire hydrant, natural ground movement, and adding additional pumping capacity to the water system. Because most of these factors can not be anticipated or controlled by Central Arkansas Water, it is necessary to address the situation after it has happened.
- Determine if the discoloration is in your hot water or your cold water. If only your hot water is affected the problem most likely is in your hot water heater and you will have to address it as a maintenance issue.
- If your cold water is affected, use as little hot water as possible to keep the discoloration out of your hot water tank.
- If your water is just slightly discolored the color of a brown paper bag or lighter, open all and only your cold water taps and let them run 5-6 minutes.
- Flush your toilets 2-3 times.
- If the initial cold water flush does not clear up the problem, wait about an hour and repeat flushing. This amount of water should not affect your water bill.
- Do not wash laundry in discolored water, it will discolor light clothes. If your water becomes discolored during a laundry in cycle, keep the laundry damp until the water clears. Rewash the clothes, DO NOT USE CHLORINE BEACH.
Most often low pressure is a problem with the private plumbing and not something Central Arkansas Water can remedy. Things like galvanized piping, faulty pressure regulators, and stopped up faucet screens can cause low pressure. At the customer’s request Central Arkansas Water will perform a pressure and flow test at the meter to confirm there is adequate water to and through the meter. A comparison test will be done at an outside faucet if one is accessible at the front of the house. A note will be left reporting the results. The customer need not be home at the time of the test.
To ensure that water pressure is sufficient to all our customers, it is necessary for Central Arkansas Water to maintain a higher pressure in the water mains than is recommended for your plumbing. Refer to the Arkansas Department of Health (ADH) Plumbing Codes (Arkansas Plumbing Law) for approved ways to regulate the water pressure after it leaves the water meter. The water meter does not regulate the pressure in any way.
Central Arkansas Water does not have any records on how your plumbing lines are run, where your shutoff valve is or where your pressure regulator might be.
Water is delivered to your neighborhood by a water main system. Generally a street will have only one main running down it. To get the water to the customers on the opposite side of the street Central Arkansas Water will run a SERVICE underground from one side of the street to the other. The main is probably on your side of the street and we have to dig in your yard to tap into the main for the service line.
Leaks on mains, services, valves, and fire hydrants will not affect your bill. Some meter leaks on the outlet side of the meter can have an affect on your consumption and if that is the case you will be advised so you can contact Customer Service for an adjustment.
Central Arkansas Water maintains the public mains, valves, fire hydrants, services, valve boxes, meter boxes and water meters in our system. We also maintain approximately 1 – 2′ of pipe on the outlet side of the meter. This is referred to as a ‘tailpiece’. Any leaks at the connection to the “tailpiece” and on up to and into the structure is considered plumbing and is not maintained by Central Arkansas Water. Some commercial properties have “Private Facilities” and those are NOT maintained by Central Arkansas Water. Contact Central Arkansas Water if you are not sure if your facilities are maintained by Central Arkansas Water.
The valve on the water meter is for use by Central Arkansas Water personnel. If we inspect the meter and find the shutoff valve operates to our satisfaction it will be left as is. The Arkansas Health Department Plumbing Code requires the customer to have a shutoff valve outside the meter box that will shut off the water to the entire structure in case of an emergency. It is a good idea to locate your shutoff valve, be sure it is in good operating condition and mark it so it is easily operated in case of an emergency.
When it is necessary to excavate on your property Central Arkansas Water will make every effort to return the site to the condition we found it. Depending on the time of year this can take several weeks if sod and plant material is not available at the time of the initial excavation.
Meters, like other equipment, age with time. We change out meters to ensure accurate use of the meter.
As soon as the new grade is established call Central Arkansas Water’s Distribution Dispatch 501-377-1239 and they will send someone to adjust the boxes. Be sure to give Central Arkansas Water a few days notice because it is not always possible to respond to such requests immediately.
Arkansas state law requires anyone making an excavation to notify owners of underground utilities of their intent to dig in a specific location. The white lines are the area of the intended excavation and the colored lines are the location of underground utilities. You may want to visit the Arkansas One Call Home Page for more details.
It is not always necessary to issue a Boil Order every time the water is turned off. There are several factors that are considered before a Boil Order is issued. If it is determined a “Boil Order’ is required you will be notified either by a door hanger or signs posted in the affected area. Additionally the media will be notified for broadcast.

Central Arkansas Water personnel are not plumbers and are not qualified to answer plumbing questions. You may find it helpful to visit the Arkansas Department of Health site and browse the “Plumbing Law” section, Division of Protective Health Codes Services Page.
Keeping our customers informed is a priority with Central Arkansas Water. If Central Arkansas Water has a planned project that requires the water to be off, every effort will be made to notify our customers prior to the shutdown.
However, many times there are spontaneous breaks or breaks caused by contractors hitting the water lines. In those emergency situations we will respond as rapidly as possible to get the water shut off, make repairs and get the water back on. Even in an emergency we will make every effort to keep our customers informed.
Because Central Arkansas Water employees are not plumbers, we do not specifically identify plumbing problems or answer specific plumbing questions. To get the problem repaired the Arkansas Plumbing Code allows a property owner to make repairs on his own plumbing lines. If you are not the property owner and/or do no feel you can make repairs, we recommend you check the Yellow Pages for a licensed plumber for advice and assistance.
A cross-connection is a DIRECT, INDIRECT, or a POTENTIAL connection between Central Arkansas Water’s distribution system and another system of questionable quality. For example, the most common cross-connection is a common garden hose. If the garden hose happens to be connected to chemical applicator, at the same time there is a reduction in system pressure, water can be sucked back through the hose and into the public water mains.
Normally water flows from the distribution system through the customer’s meter and into the facility. Backflow is the reverse of flow of water from its normal direction back into the distribution system. This occurs when a cross-connection exists.
Backflow may occur when there is a loss of system pressure or the customer’s water pressure increases above that of Central Arkansas Water’s distribution system.
Two types of backflow are BACKSIPHONAGE and BACKPRESSURE.
- BACKSIPHONAGE occurs when low or negative pressure on the supply side of the system causes the reversal of the normal flow of water. It may be caused on the supply side of the system when there is a break on a water main, increased water usage during fire fighting, or when a motorist hits a fire hydrant and causes damage.
- BACKPRESSURE occurs when the water pressure within the customer’s plumbing system exceeds the pressure of the water utility’s distribution system. Backpressure may be caused by differences in elevation, booster pumping, or a chemical injection system.
The primary hazard associated with cross-connections is contaminated water being drawn back into the public water system. If consumed, the contaminated water can cause serious illness.
The Arkansas Department of Health has documented numerous cases of backflow on public water systems within the state and across the country. Backflow incidents are not always documented; therefore, it is unknown just how often incidents occur.
In 1995, the Arkansas Department of Health amended Act 96 of 1913 (Rules and Regulations Pertaining to Public Water Systems) and mandated that all public water utilities institute a Cross-Connection Control Program. The intent of the program is to locate, identify, and eliminate, or protect against, all potential cross-connections. Customers found to have a cross-connection or a potential cross-connection must be isolated from the public water system. Central Arkansas Water requires the installation of a Reduced Pressure Zone Assembly (RPZA) on all water services where a potential cross-connection may exist. RPZAs, unlike older non-testable devices such as swing check valves, dual check valves, and atmospheric vacuum breakers, are testable in place to assure proper operation.
Central Arkansas Water requires the installation of an RPZA on the water service of all facilities that pose a potential hazard to the public water supply.
State regulations also require the protection of the public water system from the potential of backflow from Fire Sprinkler Systems. The installation of a Double Detector Check Valve Assembly (DDCVA) is adequate unless the Fire Sprinkler System has additives or a secondary water source is present. In this situation, we require the installation of an RPZA.
Underground Irrigation Systems pose a high health hazard and also require the installation of an RPZAs.
All commercial and industrial customers within the Central Arkansas Water service area periodically will receive a survey questionnaire in the mail. We ask that you complete and return the Survey Form to us. Central Arkansas Water then will determine whether state regulations require the installation of an assembly. In some cases, it may be necessary for Central Arkansas Water personnel to perform an on-site inspection. If the survey requires an on-site inspection, a service charge is applicable.

The Arkansas State Plumbing Code (ASPC) mandates that only licensed plumbers may install assemblies. If the assembly is on a Fire Protection System, then only personnel licensed by the State of Arkansas and holding a Registered Mechanical Engineer license or employed by a company licensed by the Fire Protection Licensing Board may install assemblies. The vent of the relief valve on the RPZA shall be between 12″ and 30″ above ground. Horizontal clearance shall be 30″ between the assembly and an adjacent wall, 12″ on the opposite side, 8″ at each end, 6″ above the highest point, and 12″ underneath the assembly. Assemblies 3″ or larger in diameter shall have adequate support and all installations must have a strainer and blow-off. An assembly cannot be mounted in a vertical position unless it specifically designed for this orientation.
RPZA’s must be installed above ground on the customer’s side of the meter and before the first point of use. If the installation is inside a building, it must be in a location providing adequate drainage for discharge.
Central Arkansas Water recommends that if the assembly is to be in service year around, an enclosure be provided to prevent it freezing. Enclosures also may discourage vandalism and theft. As of 2003 the Arkansas State Plumbing Code (607.14.1) requires outdoor enclosures for backflow devices comply with ASSE 1060.
The ADH mandates the testing of assemblies within 10 days of installation and annually thereafter.
Only personnel with Assembly Tester Technician certification from the ADH may test backflow assemblies in the Central Arkansas Water service area. Only personnel with a valid license from the Arkansas Fire Protection Licensing Board and the AHD may test assemblies on Fire Protection Systems. A listing of Certified Assembly Tester Technicians may be found in the Yellow Pages under “Backflow Prevention Devices & Services,” “Sprinklers – Lawn and Garden,” and the plumbing section. The following web sites also provide listings of testers:
Under the Arkansas State Plumbing Code, the customer is responsible for all costs associated with the installation, testing, and maintenance of backflow assemblies on their premises.
The hardness of the water provided by Central Arkansas Water is between 1.0-1.7 grains/gallon or 17-29 mg/L. This is considered a “soft” water.
Chlorine is added to the water for disinfection. It kills disease-causing microorganisms called pathogens. The Safe Drinking Water Act requires that a chlorine residual be maintained throughout the entire distribution system. To accomplish this, sufficient amounts of chlorine must be added at the treatment plants and at booster chlorination sites located in certain areas of the distribution system.
The white particles are possibly pieces of the dip tube from your hot water heater. Several manufacturers of hot water heaters used polypropylene dip tube between 1993 and 1996. These dip tubes have a tendency to fail and break up. If you run out of hot water quickly, this is a sign your dip tube has failed. Another test is to clean the aerator and then run only cold water. If the particles do not appear, run your hot water and see if the particles appear. If so, this is a sure sign they are coming from your hot water heater. If your dip tube has failed, you need to either replace the dip tube or your hot water heater. It is a good idea to flush your hot water heater annually.
Yes, to the level of 0.8 mg/L as recommended by the Arkansas Department of Health. Fluoride in drinking water has been shown to decrease the incidence of tooth decay. USEPA has established an upper allowable limit of 4.0 mg/L for fluoride.
Coliforms are generally harmless bacteria that are found in the intestines of warm-blooded animals. The presence of coliforms indicate that the water may be unsafe to drink because pathogenic bacteria are also found in the intestines of animals and humans. This is why coliforms are called indicator organisms. The presence of coliforms in a water sample indicates that pathogenic bacteria may also be present.
No. Drinking water is disinfected to kill all the pathogenic (disease-causing) organisms. Most microbes are harmless.
Yes. Central Arkansas Water has never had a compliance violation of the federal Safe Drinking Water Act or the State of Arkansas’ Rules and Regulations Pertaining to Public Water Systems.
Call the Central Arkansas Water laboratory at 501-223-1574 with all water quality problems except discolored water. Laboratory personnel will sample your water and investigate. If you are experiencing discolored water, call the Distribution Department’s dispatch center at 501-223-1550.
Central Arkansas Water uses conventional treatment at both its water treatment plants. The treatment processes include coagulation, flocculation, sedimentation, filtration, and disinfection. Raw water from Lake Winona and Lake Maumelle flows to the Ozark Point Treatment Plant and the Jack H. Wilson Treatment Plant.
The water first enters the treatment plants at flash mixing chambers, where the coagulant aluminum sulfate (alum) is added for particle removal, and lime is added for pH adjustment. Activated carbon is added seasonally for taste and odor control. Water then flows to the flocculation basins where the water and chemicals are gently mixed to form “floc”, which consist of agglomerations of suspended particles such as silt, bacteria, and algae. The water then flows into sedimentation basins where most of the “floc” settles out and is removed from the water. The water then flows downward through filters of sand and anthracite where any remaining “floc” particles are removed. Before and after filtration, chlorine is added for disinfection.
Finally, fluoride is added for the prevention of cavities in children’s teeth, phosphate for minimizing corrosion in the distribution system piping, and lime for final adjustment of the water pH.
For Central Arkansas Water, monitoring and testing of the water begins at the raw water source and, for some potential contaminants, continues to the tap. Our laboratory and treatment personnel conduct approximately 155,000 water quality test every year at the various stages of water production, treatment, and delivery-an average of 425 tests per day.
In addition, the ADH performs approximately 600 water quality analyses on samples collected from our raw water sources, Lake Maumelle and Lake Winona; our treatment facilities, the Jack H. Wilson Treatment Plant and the Ozark Point Treatment Plant; and our distribution system of more than 2,200 miles of water mains.
