Frequently Asked Questions






My water is cloudy. What causes this, and is it safe to drink?

Cloudy water is caused when dissolved gases in the source waters are released under atmospheric pressure and increased temperature. The gases present are mostly oxygen and carbon dioxide, and do not pose a threat to public health. The Water Authority has two wells that are the primary source of milky water, Plank Road and Kinns Road. Customers in that area, and north, will be most likely to experience milky water. If left in a glass for a minute or so, the air will dissipate from the water, although drinking the water without letting the air escape is not harmful.


My water is discolored. What causes this, is it safe to drink, and what do I do to get rid of it?

Discolored water results when water traveling through the water mains reaches high enough velocities to stir the iron and manganese sediment lying in the bottom of the water mains. Water main breaks, fire fighting activities, and extremely high system demand are typical causes of discolored water. There are no health risks associated with this type of problem, as the particulate matter causing the discoloration is simply iron and manganese oxides, and are not harmful. If you experience this problem, the easiest way to eliminate the discolored water from your system is to run as many cold water faucets, including bath tubs, sinks, and outside spigots, as possible at the same time. This will create a high enough flow rate from the water main to your home to clear out any sediment which may have found its way into your service line. If the problem does not clear up within a few minutes, it is possible that the sediment in the water main has not settled out yet. In this case, wait an hour or so and try it again.


Why does my hot water smell like rotten eggs?

 The most common cause of "smelly water" is a non-toxic sulfate reducing bacteria, scientifically known as Divibrio Sulfurcans. This bacteria creates the energy it needs to survive by converting sulfate (SO4 ) to the hydrogen sulfide (H2S) gas you smell in the water. When chlorine is added to the public water supply for disinfection purposes, these bacteria are destroyed, removing the odor associated with their presence. These bacteria can, however, under certain circumstances, reemerge within the water system inside the home. Long periods of no water movement, like a toilet that does not get used often, or a hot water tank that does not get "turned over" enough, can cause the chlorine to dissipate out of the water, creating an ideal environment for bacterial growth. This problem is even more prevalent in softened water containing sodium in place of calcium and magnesium. The added compounds of the salt to the water speed up the depletion of anode rods used to protect the inside of the tank from corrosive energies. Most new hot water tanks have these anode rods in them. The rapid depletion of the anode rod, or more precisely, the cathodic reactions that cause the depletion, create a release of hydrogen ions into the water which are then converted to hydrogen sulfide gas. There are three possible solutions to this problem. 1) Remove the anode rod from the hot water tank. 2) Increase the temperature inside the hot water tank to 140 degrees Fahrenheit which will kill the bacteria. 3)Chlorinate the hot water system. Directions for chlorination can be found on the Rheem web site under their FAQ section on smelly water.


I am re-siding my house and noticed the water meter's remote reader is attached to the existing siding. Do I need to have the Water Authority come out and remove it, or can I do it myself?

The remote can be removed from the siding by the homeowner by disconnecting the wire at the terminals and unscrewing the remote from the siding. When replacing the siding on the home, make sure to bring the wire back through the new siding for reattachment. Once this portion of the siding is complete, contact the Water Authority for a service technician to come out and reattach and recalibrate the remote.


My water bill seems unusually high. Is it possible that I used that much water?

Most customers have very consistent water usage from one quarter to the next. Sometimes summer lawn irrigation can produce some surprisingly high bills, especially for homes with automatic lawn sprinklers. If your bill seems high, check the reading on your meter to see if the meter was read correctly by the Water Authority. If the reading checks out, there are a number of tests that can be performed to try to find the cause of the additional usage. If you have an automatic sprinkler system, take a meter reading before a cycle and after a cycle to see how much water is used each time your sprinkler system runs. To see if something within the home is "stealing" water, take a meter reading before you go to bed at night, and then read it when you get up in the morning. If there was water used while you were sleeping, there is a good chance that something is leaking somewhere. The two main culprits for unintended water consumption within the home are toilets and water softeners. If the flapper valve within the toilet tank is leaking water into the toilet bowl, the tank will periodically have to fill to replace the lost water. This type of situation could go undetected for quite a while resulting in a high water bill for the customer. Water softeners periodically backwash themselves with fresh water to regenerate. Sometimes the backwash valve can get stuck in the open position causing water to be continuously wasted to the sewer system. This is a situation that very often goes undetected because there is little associated noise created other than a soft trickling sound in the sewer pipe. This can result in a lot of water being wasted and some really high bills. If you find this to be happening in your home, turn the feed to the softener off and bypass if possible, and get the unit repaired immediately.


A Boil Water Advisory has been issued for my area. What does it mean, and what should I do?

A Boil Water Advisory (BWA) is a preventative measure issued to protect the health of the community from water borne infectious agents. A Boil Water Advisory is issued only after careful consideration among representatives from public health, regulatory agencies and municipal departments. A Boil Water Advisory does not necessarily mean that a contaminant has been found to have entered the drinking water supply, in fact, most BWA's are initiated as precautionary measures only.

Create a supply of water for cooking, drinking and tooth brushing.

   1. Bring the water to a rolling boil for 1 minute. Timing starts when the water starts to bubble.

   2. Cool the water then place in clean containers for use or refrigerate.

Hot soapy water can be used for dishwashing and kitchen / bathroom surface cleaning. As a precaution, add one tablespoon of bleach per gallon.

Laundry water does not need to be treated. Unless otherwise noted, water for showering does not need to be treated.

If the water is not safe for drinking because of germs (bacteria, viruses or parasites), good hand washing with soap and water should be followed up with hand disinfection with alcohol-based disinfectant.


What is the Basic Service Charge found on my water bill?

The CPWA charges a quarterly basic service charge to all customers.  This charge is separate from usage charges and is a fixed charge based on meter size.  The charge covers costs that are the same or similar for all customers, including the cost of eventual meter replacement, the cost of customer billing and repayment of debt on infrastructure.


My bill says I have an intermittent or continuous leak. What does this mean?

Most of the water meters in the CPWA system have leak detection built in.  Every 15 minutes, the meter determines whether there was water use within that interval. 

If the meter sees usage in at least half of the 96 15-minute intervals in a 24-hour period, it will indicate an intermittent leak.  The most common cause of this is a toilet that is slowly leaking water through the flapper in the bottom of toilet tank, causing the toilet tank to refill periodically.

If the meter sees usage in every 15-minute interval in a 24-hour period, it will indicate a continuous leak.  Common causes are leaks in irrigation systems, water softeners stuck in backwash, or slow drips in faucets.


What is the average water use for a CPWA customer?

The national average for water consumption for a single person is 80-100 gallons per day.  This number drops a little as more people are added to the household, as some water-consuming tasks remain constant, regardless of the number of people (lawn watering for instance).  The average quarterly bill of all residential customers on the CPWA system is around 20,000 gallons. 


What is the hardness of my water and do I need a water softener?

The CPWA delivers water to its customers from a number of different sources, so the answer is not the same for every customer.  Generally speaking, customers south of Route 146, and all customers in Rexford, receive water from groundwater sources that are high in hardness.  The hardness is typically around 290 mg/l, or 17 grains/gallon.  High hardness can cause issues with calcium deposits on glassware, flatware, shower doors, furnace humidifiers, fixtures, etc.  Customers in this area may choose to install a water softener to alleviate these issues. 

Customers north of Ushers Road receive most, or all of their water from our connection to the Saratoga County Water Authority.  This water is extremely soft and a water softener should not be needed.

Customers in the section of the system between Route 146 and Ushers Road may see some varying level of hardness, as both groundwater and surface water sources can converge in this area.  If you regularly notice hard water issues within the home, consideration could be given to installing a water softener.

If you are in an area where the hardness level may be questionable, you can bring a sample of your water to the CPWA office in a clean container (a bottled water bottle is always a good one) for hardness testing by our treatment plant staff.


There are pink stains, or a pink jelly-like substance in my toilet or shower. What is it and what do I do to get rid of it?

Each year, a few customers call to ask us about pink stains or residues that occasionally develop in moist areas in their homes. They generally observe this in toilet bowls, around sink and tub drains, on shower curtains or other shower surfaces, and even in pet water dishes.  The customer naturally wants to know if there is something wrong with his/her water.

No, a pink residue is not a problem with your water quality, and is not harmful in this situation.  It is evidence of bacteria that are common inhabitants of our environment.  The most typical of these bacteria is one known as Serratia marcescens.

These bacteria come from any of a number of naturally-occurring sources, such as soil, mulch, dust, and surface waters, and they thrive in an environment that is moist and high in phosphates.  More people indicate the problem occurs in the summer months when temperatures and humidity are higher, and especially if windows are kept open for any length of time.

Serratia will not survive in chlorinated drinking water.  However, where water stands long enough for the residual chlorine disinfectant to dissipate, such as a toilet in a guest bathroom, or on a shower curtain, the pink color may develop.  Customers who remove the chlorine from their water by use of an activated carbon filter may also be more likely to experience the problem.

How Can I Get Rid of the Stains?

Once established, Serratia is difficult to eliminate entirely.  However, regular and thorough cleaning, followed by disinfection with chlorine bleach, is the best means to control the organism.

  • Wipe bathtubs, shower walls and curtains, and around drains in order to dry them, followed by spraying or misting with a product that contains bleach or other disinfectant.
  • For toilets, clean the bowl regularly. You may wish to add ¼ cup of bleach to the toilet tank, let stand for 15-20 minutes, and then flush the bowl a couple of times to fully rinse the disinfectant. Bleach should not be left in the toilet tank for prolonged periods, however, as it will damage the rubber seals and valves inside.
  • Use care with any abrasives to avoid scratching a fixture or surface, which will raise the likelihood of bacterial growth.
  • Clean pet water bowls in a similar manner. Leave a bleach solution in the bowl for 15-20 minutes, followed by thorough rinsing.

Clean off the pink residue, and then mist with a product that contains chlorine bleach.


What causes black rings around the toilet and faucet aerator?

The presence of a black jellylike substance in moist areas of the kitchen or bathroom is likely a fungus called Aspergillus niger that occurs naturally in our environment and travels through the air. Given the right growing conditions, Aspergillus niger will colonize and produce black stains on surfaces.

Typical Source: If water stands long enough it can lose its residual chlorine disinfectant. Constantly damp surfaces are also a prime growth site for black mold. It can commonly be found in the following locations:

• Kitchen and bath faucets (aerators)

• Dishwashers

• Washing machines

• Toilet tanks and bowls

• Showerheads

• Bathroom tile

• Shower curtains

• Drains

Kitchens and bathrooms are the most common sites for black mold because these areas tend to have a warm and humid atmosphere. These locations also provide the fungus with a source of organic nutrition from shampoo, soap, conditioner, hairspray, liquid dish detergent and food particles.

Cleaning Recommendations Once established, black mold usually cannot be eliminated entirely. To help reduce growth, treat areas with a spray product that contains bleach or another disinfectant. Improving ventilation in the affected area may also help reduce growth.

To clean your bathtub faucet:

• Scrub the inside with a toothbrush • Spray the inside with a disinfectant that contains bleach • Rinse thoroughly

To clean your sink faucet and aerator:

• Remove the aerator and soak in a bleach solution

• Use a toothbrush to scrub and loosen any black mold on the aerator screen and faucet opening

• Rinse thoroughly


Does the CPWA add Fluoride to the water?

The CPWA does not fluoridate the water it serves to its customers.  There is some naturally occurring fluoride in some of the CPWA’s source waters, but these levels are much lower than what a dentist would recommend for developing teeth.  Customer who are concerned about getting enough fluoride for good dental health should consult their dentist.


Can I connect my home or property to the CPWA water system?

The CPWA has a policy requiring that a property must have water main located immediately in front of, or across the street from, at least some portion of their property.  Properties that meet this criterion can connect and are required to complete an application for metered water service, pay the appropriate tapping, hookup and meter fees and have a contractor perform all work necessary to complete the connection from the shutoff on the property to the inside of the home.

Properties that don’t meet this criterion are required to extend water main to that location from its existing terminus.  There are a couple of ways that this can happen.


One way for a resident to extend water main to their property is to present an engineered drawing of the proposed water main extension to the CPWA for review.  Once reviewed and approved by the CPWA Administrator, the resident would then hire a contractor to install the water main per the approved plan.  The property owner would be responsible to pay all costs associated with the extension, including water main testing, the installation of the service line to the house and any fees due to the CPWA for inspection, connection and meter.  Once installed, the water main would become the property of the CPWA, who would be responsible for all future maintenance and repair of this line.

Creation of a Special District

The other way that water can get extended is to form a water district.  Residents in a given area, that are interested in receiving water service from the CPWA, can petition the Town of Clifton Park to create a special district to extend water service to their homes or properties.

The creation of a special district allows the Town to finance the project over an extended period of time and recover these expenses annually on the tax bills of the properties within the limits of the special district.  This spreads the cost out over a long period of time and makes it more affordable to the property owners requesting water service.

Once the petition is received by the Town, their engineer would determine the cost and feasibility of the extension and present these findings to the property owners within the proposed district area.  At that time, the property owners will each decide whether they are willing to incur the costs associated with the project.  The percentage of property owners within the district area that are willing to commit to the expense will determine whether the project proceeds or not.

Property owners within the special district area can expect to pay annually on their property taxes for the cost of installation of the water main until the bonds are paid off in full.  They can also expect to pay for installation costs of the water service to their home from the newly installed water main, as well as any hookup and meter fees due to the CPWA.


I have a leak in my water service line. Am I responsible for the repairs?

Customers of the Clifton Park Water Authority are responsible for repairs and/or needed replacement of their water services from the service valve (typically located at the edge of the public right-of-way) to the home’s interior plumbing.  The CPWA is responsible for repairs from the water main to the service valve.  Customers are also responsible for any repairs to internal plumbing inside the home with the exception of the water meter itself.

Customers performing repairs to, or replacement of, a water service line will need to inform the CPWA prior to commencement of work, as the repair will need to be inspected by CPWA staff prior to backfill.

Repairs to water service lines can be costly.  There are companies that sell insurance to homeowners, protecting them against unexpected large expenses for water line repairs.  The CPWA does not endorse any particular company, nor does it feel this type of insurance is necessary for all customers.  It is up to the individual homeowner to determine whether insuring against unexpected repair costs is worthwhile and which insurer they should purchase insurance from.
