3. What do I do if I think my bill is wrong?

If you feel there is an error with your bill call our Customer Service center Monday – Friday 7:30am – 6:00pm at 770.423.1000. Our staff can schedule a service order request to have your meter reading verified and checked for leaks.

4. How do I check for 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. To download a guide on reading meter and checking leaks, please .

5. If I have a water leak, does the County make repairs?

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

6. Can the County provide a list of plumbers?


7. Why do I have to pay for water when a pipe bursts at my residence?

It is Cobb County’s responsibility to provide water to all our customers at the water meter location. Cobb County Water System is not responsible for any private plumbing system issues. The home plumbing system consists of all the pipe and fixtures that are on your property after the water meter connection. All repairs and costs associated with a plumbing system failure are the responsibility of the customer.

In some cases Cobb County Water System may offer a nominal leak credit to offset a portion of the costs associated with a leak. For more information click here.

8. 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.

9. How do I read my meter?

Please to download a Guide on how to read your meter.

10. 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 7:30am - 6:00pm at 770-423.1000 and make a payment or payment arrangement.

11. 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.

12. 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.

13. If I have a sewer backup, who should I contact?

Contact our Emergency Service at 770.419.6201

14. My water tastes and smells funny?

Different factors can affect the taste and smell of your water. To report problems with your water call our Customer Service center Monday – Friday 7:30am – 6:00pm at 770.423.1000

15. 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.

16. 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.

17. Who can I contact for water quality questions and concern?

Contact our Customer Service center Monday – Friday 7:30am – 6:00pm at 770.423.1000

18. 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.

19. 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.

20. How often will I receive a water bill?

Approximately every month (every 28-32 days).

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

We bill approximately 175,000 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.

22. 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.

23. Does the Water System accept “Letters of Credit” from other

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.

24. 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 thirty-two day window.

36. 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 770-423-1000. 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 ($1.53).

37. 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.

38. 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 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)429-3432

The air in the pipes should rise to the highest point and be released, alleviating the noise problem.
