FAQ Topics

What are the current water rates?
Do you offer budget billing?

No, because budget billing does not promote conservation. A customer on budget billing may not realize that they have a leak or other water-related problems at their property.

Should I continue to pay my bill if my meter is not functioning properly, I am disputing a balance or I have an adjustment pending?

Yes, we recommend that you call our Customer Service center Monday – Friday 8:00 am - 5:00 pm at 770-419-6200 and make a payment or payment arrangement.

What happens if my bill is not paid by the due date?

If your bill is not paid by the due date shown on the bill, you are subject to a $10 late fee and your service may be disrupted.

If my service has been interrupted, is there a reconnect fee?

Yes, there will be a $50 administrative fee during normal business hours. A premium fee of $75.00 is added for after hour service restoration, Monday – Friday between 6:00 PM - 8:00 PM. The premium fee must be paid the next business day by noon to avoid service disconnection.

How often will I receive a water bill?

Approximately every month (every 28-32 days).

I get paid at the beginning of the month. Can you change my billing cycle to coincide with my pay date?

We bill approximately 197,000+ customers per month. Because we send out so many bills, we bill customers daily. We have the county split into cycles. We read 1 or 2 cycles per day and bill the same day. Your billing date is based on which cycle you live in. Unfortunately, there is no way for us to manually change your billing cycle.

When do I get my deposit back?

A deposit shall be held on the account for a period of not less than 24 months. After an account has established a perfect payment record for a consecutive 24 months period, the deposit shall be refunded back to the account. A perfect payment record shall mean there are no incidents of delinquency or returned checks or a regular pattern of payment when past due.

Does the Water System accept “Letters of Credit” from other utilities?

No, letters of credit from other utilities are subjective documents and are not regulated, nor is there a standard to which they are compared. We believe requiring a cash deposit on water bill accounts reduces losses thereby assuring the lowest rates for all of our customers.

When should I expect my first bill?

You should expect your first bill within 35 days upon activation. Cobb County Water System strives to read water meters in a consistent manner and reach all of our customers within twenty-eight to a thirty-two-day window.

Can I pay my bill over the phone?

Yes, Customers have the ability to make payments on their account over our Interactive Voice Response System at 770-419-6200. Payments will be posted immediately.

What are the system requirements for using the online payment option?

All major browsers.

Is there a fee for making a Credit Card Payment?

No, our customers may choose to pay with American Express, Master Card, Visa, Discover or Visa/Master Check Card at no charge.

How long does it take the bill to process using the online payment option?


What if my consumption goes up into a higher tier because of an extended billing period caused by Cobb County Water System?

Please call Cobb County Water System at 770-419-6200. If Cobb County Water System fails to read within our preferred 28-32 day window and consumption is placed in an upper tier Cobb County Water System will adjust your bill for the difference between the higher and lower tier. This credit is only provided if your usage is pushed into the next tier by our failure to read within that 28-32 day window. For example, if your use is normally 3,000 gallons and you are billed for 4,000 gallons due to an extended billing period; Cobb County Water System will credit the difference between the first tier and the second tier for the 1,000 gallons billed at tier 2.  Visit our current water rates and use our water calculator.

Why are the sewer charges higher than the water charges?

This is primarily due to the cost of building, maintaining, and operating both the sewage collection system and treatment plants capable of removing contaminants in wastewater prior to returning it to lakes and rivers. Our treatment processes meet or exceed all state and federal standards.

Why are street light charges on my water bill?

When the program began for street light service, there was no billing system in place. Utilizing the Cobb County Water System’s existing billing system proved to be cost-effective; whereas, creating a separate street light billing system would have significantly added costs. The street light funds go to the county’s general fund to pay for utility costs and other maintenance associated with providing this service. For street light repairs/outages, please use the online form, or contact your power company at one of the numbers listed below:

Cobb EMC: 770-429-2100
Marietta Power: 770-794-5125
Georgia Power: 1-888-660-5890
Greystone: 770-942-6576

How do I check for water leaks?

A small leak, about the size of the head of a pin, dripping at one drop a second can add up to 7 gallons of water per day. A large leak, the kind most often found in toilets, can waste 200 gallons of water or more per day. Check out the following when you suspect a leak:

  • Faucets – Check faucets in the bathroom and kitchen periodically. Most often, worn washers are the cause of dripping faucets.
  • Sprinkler System – Broken sprinklers heads or damaged underground pipes are common sources of sprinkler system leaks. Watch your system run at least once a month to spot problems early. Usually, leaks are easy to fix. Do-it-yourself books with easy to follow instructions are available at libraries and stores.
  • Toilets – Check for toilet leaks often. The most common cause of a leaking toilet are:
    1. Float device set too high, which causes water to run into the overflow tube and
    2. A warped or cracked flapper. Toilet leak kits are available. The kit contains tablets that are dropped into the toilet tank. After the tablets are placed in the tank wait 15 minutes, then check the toilet bowl. (Remember, don’t flush during this time.) If the water in the bowl changes color, you may have a leak. Download a guide on reading meter and checking leaks.
If I have a water leak, does the County make repairs?

No, the Water System is not responsible for leaks between the meter and the house or in the house. The maintenance and repair of pipes and fixtures after the water meter are the sole responsibility of the customer. This includes any charges associated with a leak.

Can the County provide a list of plumbers?


Who do I contact if there is a lot of water pouring out of my meter box or running down the street?

To report a large volume leak, call our 24-hour Emergency Dispatch at 770-419-6201.

Is every property eligible for the program?

This program is available for Cobb County Water System’s customers that are billed commercial water rates including multi-family housing, schools, businesses, hospitality, etc. The property must have been built in 1992 or earlier and have toilets that use more than 1.6 gallons per flush. The goal of the program is to retrofit these properties with high-efficiency fixtures. Buildings constructed during 1993 and after were required to have low flow toilets because the Federal Energy Policy Act of 1992 mandated low flow fixtures in all new construction.

Does my property have to be a Cobb County Water System customer to take advantage of this program?

Yes. In order to qualify for this program, your property must receive a water bill from Cobb County Water System. The rebate is a credit on the account holder’s water bill. We cannot issue a credit if there is no water bill. We do not issue cash or checks for the rebate program.

How can my business participate in the program?

As long as the property was built in 1992 or earlier, the property can purchase EPA WaterSense labeled toilets and submit the original receipts, and proof of both installation and property age to:

Cobb Water only has a fiduciary responsibility with the account holder of the master metered water account, not the individual residents within the community. Cobb County Water System will only issue a credit to the community’s water account.

We cannot give individual rebates to condo owners without a Cobb County Water System account. We only have a fiduciary relationship with our account holder. If the condo association wishes to participate in the program, the association president or management company should review the procedure for participating in the rebate program and determining how they will credit participating residents.

These toilets have been certified by a third party to ensure high performance and long-term water savings. Look for the WaterSense Label to ensure the product installed qualifies for the rebate.

Do I have to rebate the entire property to participate in the rebate?

No, but we will only process one commercial rebate per property. It is most beneficial to the property to rebate as many toilets as possible at once. The cap on the rebate program is 100 toilets per property. How a property handles this is up to them.

If you have a particular plumbing situation where none of the approved toilets will fit in your existing home, please contact Cobb Water at 770-528-8214, prior to purchasing them to discuss the situation.

How do I participate in the program?

Will I automatically get my credit?

The toilet rebate program has a designated annual budget. Customers are advised to check with the Water Efficiency Office to see if funds are available. The Water Efficiency Office cannot guarantee funds will be available when your application is received. The customer must have purchased a toilet from the approved lists and be in a home built prior to 1993.

What is a WaterSense High-Efficiency Toilet?

These toilets are the only toilets eligible for a $100.00 rebate. WaterSense is the Environmental Protection Agency's labeling program for water efficiency, modeled after the Energy Star labeling program. The WaterSense labeled toilets only use an average of 1.28 gallons of water per flush and have passed rigorous third-party testing standards.

Why do the lists have tanks and bowls listed separately?

Most toilets are sold in two pieces. Be sure to get both a tank and bowl that are listed together on the toilet lists. A representative at the retailer should be able to assist you with this. Make sure and bring the lists with you to the retailer.

Do I have to buy the toilet at a particular store?

No. As long as the toilet is WaterSense labeled, a customer can buy it from any retailer, even online, but we do need the original invoice sent in with the application. Cobb Water System advises customers to keep a copy of the receipt, for their records.

No. The decision on installation is up to the individual customer.

Are all of these toilets available at all retailers?

Probably not. Cobb County Water System has informed local retailers about the program and encouraged them to carry stock. No retailer will have every toilet, but approved toilets are available locally.

Can Businesses qualify for this program?

The residential toilet rebate program is for single-family customers only.  We now have a commercial rebate program and you may be eligible.  More information can be found in the Commercial Toilet Rebate Program.  

What if I own rental property. Can I get the rebate?

If the property meets the program qualifications a rebate will be issued as a credit to the water bill of the account holder at the rental property. If you are not the account holder it will be credited to the current water account holder's bill (renter). Cobb County Water System will not become involved in renter landlord disputes.

I heard that EPD lifted the level 1 drought response. Are there still water restrictions in place?

Yes. All Cobb County residents should follow the non-drought outdoor water use schedule required under the Water Stewardship Act of 2010.

How do I test to see if my lawn needs water?

Use the step test to evaluate if your lawn needs to be watered: 

  • Place your foot firmly on your turf area.
  • Watch how quickly the turf springs up to cover your footprint.
  • If the turf springs up immediately (a few seconds) your turf is probably not in need of watering.
  • If the footprint remains or the turf slowly rises to eventually cover it your turf is in need of a deep watering.
How do I know if my plants need watering?

 Visually Inspect plants to see if they require water before irrigating on your day.

  • Check plants in the early morning or late evening. Plants checked in the heat of the day will always appear to need water.
  • If the plant is wilting; yellow or grayish in appearance; has dried edges or browning, or loss of flowering the plant is probably in need of water.

For more information on proper plant and landscape maintenance visit our Outdoor Water Use page or call the Water Efficiency Office at 770-528-8214.

Why does my water taste and smell funny?

Different factors can affect the taste and smell of your water. To report problems with your water use our online report form or call our Customer Service center Monday – Friday 8:00 am – 5:00 pm at 770-419-6200.

Why is my water “cloudy” or “milky” colored?

When water has been shut off at the main, this sometimes causes air in the lines. The color that you are seeing is probably due to this. You can check by filling a glass with water and letting it sit for a short time. If the water clears up, there is air in the line. To remove air from the line, turn on the cold water taps in your house and let them run for 5-10 minutes.  If water discoloring persists, email us the issue you are experiencing.  

What are the white particles in my water?

This may be due to a faulty dip tube in your hot water heater. Sometimes the plastic in the tube breaks down and this can clog your faucets and showerheads.

Who can I contact for water quality questions and concerns?

I have an open drainage ditch on my property. Does the County maintain that for me?

If the Water System has to make repairs, how long will the water be off?

The repair crew will work as efficiently as possible until the repair is completed. Unless some complications arise, you can expect to have the water turned on within 8 hours.

I reported a leak in the road over a week ago and it is still not fixed. How long does it take?

Cobb County takes management of the system very seriously. We have a leak repair prioritization policy. The most severe leaks, causing the most damage and water loss, are repaired first. Due to limited staff, this may mean smaller leaks take a little more time to repair.

What should I do if my pipes are making noise?

Usually, noise from pipes results from air in the lines. Go to the water spigot at the front of the house and run the water for a few minutes. Next, go to the highest point in the house, usually an upstairs shower. Turn on the cold water in the shower for approximately 5 minutes. The air in the pipes should rise to the highest point and be released, alleviating the noise problem.

What is an Easement?

An easement is a right provided to a person or entity to use someone else's property. The property owner usually transfers this right while retaining ownership through execution of an easement document. See our brochure entitled "Easements: What You Should Know," (PDF) for more information on easements with the Cobb County Water System.
