Fire Flow Test

If you are required to have a Fire Flow Test prior to development plan approval, please follow the procedures as listed below (NOTE: CCWS can only test fire hydrants on public r.o.w. within its jurisdiction):

Submit the attached application with all applicable data to the Cobb County Water System, Engineering & Records Division along with:

A.  An 8½" X 11" location map that clearly shows the site location. (Aero Atlas quality or go to Cobb County GIS Homepage).

B.   A check for $100.00 made payable to the
Cobb County Water System
660 South Cobb Dr. Marietta, GA 30060.

It may take up to three (3) weeks to complete the Fire Flow Test, depending on weather and other factors. A Fire Flow test is required for all projects. Copies of the Fire Flow Test must be shown on the plans. The test cannot be over 6 months old.

The 24-hour clock will not be provided by Cobb County. The Design Engineer will be responsible for providing a 24-hour pressure recording if/when required by the Fire Department.

Construction plans cannot be approved without the Fire Flow Test results being on the water plans. Please consider this when preparing your development schedule.

See a copy of the Fire Flow Test application.

Plan Review

Site Plan Review

The Plan Review Section reviews all civil construction plans for new developments and re-developments applying for a Land Disturbance Permit (LDP) to ensure compliance with Cobb County ordinances and standards.

All land-disturbing activities in unincorporated Cobb County must be reviewed and approved via the issuance of a LDP. To apply for an LDP and start the Plan Review process, please contact Community Development Site Plan Review at (770) 528-2147 or visit the Site Plan Review page for more information.

Commercial Building Permit Review

If you need a building permit in Cobb County (or a certificate of occupancy), there are three different scenarios regarding building permits/CO’s and the commercial permit application in Cobb County. The CCWS is involved in two of the scenarios and they are listed below.

1. Within Unincorporated Cobb County:

If the address is in unincorporated Cobb County, you can apply for 3 permit types (new tenant, vacant tenant or remodel) at Cobb’s new Citizen’s Access portal.  Note: you’ll need to create a user account before submitting plans.

Once your submittal is accepted by Cobb County Community Development, automated emails will be sent by ComDev to CCWS and to the Fire Marshal’s office (FMO).  When CCWS receives the email, either we will let you know what we need to see for a pre-review and where to send it, or we will release the project through to permitting.

For projects other than the three permit types above (such as a new building or a building addition), use the procedure outlined in #2 below (for city projects).

2. Powder Springs, Acworth or Kennesaw City Limits:

If the address for your project is within the city limits of Powder Springs, Acworth or Kennesaw, you will still fall under the jurisdiction of Cobb’s Fire Marshal, but you will not be obtaining a permit via Cobb County Community Development; therefore, you will be unable to use Cobb’s Citizen’s Access portal. Instead, you will request an appointment with Cobb Fire online at their website.   When it opens, scroll down and you will see the links below to request an appointment for plan review with the FM as well as the link for the commercial permit application:

     "Effective Monday, March 6, 2017, all requests for [fire marshall] plan review appointments must be scheduled through our [FMO] online process."

  • Plan Review Appointment Request
  • Commercial Permit Application

The Fire Marshal’s office will then send you a form-letter email confirming the date/time of the meeting and details of items required for review.  One item on the list will be the Commercial Permit Application Form (found on the same page as the appointment request), which they will instruct you to complete and send to the Water Department electronically.  Once you complete the first page electronically online, print it as a pdf, and send it to us immediately after requesting the appointment. There is a link at the top of the 2nd page ([email protected]) that you can click on and it will open an email box to submit the application to our office. Include a short description or scope of work on the project.

When we receive your application, it will initiate our review and we will let you know what we need to see and where to send it, or, if no CCWS approval is required, we will sign your form indicating same and return it to you.  You will then print the application form and take it with you to your meeting with the Fire Marshal.

3. Austell, Marietta, or Smyrna City Limits:

If the address is within the city limits of Austell, Marietta or Smyrna, you would not fall under the jurisdiction of Cobb’s Fire Marshal. Instead, you would submit your project to the City in which the business will operate. Determination of jurisdiction (city limits) can be made using the property search page at the Cobb Tax Assessor’s website. Note that although the project is within the city limits of one of these three municipalities, it may be a Cobb County Water System customer, so the city may have you contact our office.  We’ll need the address to make this determination and to let you know how we can coordinate a CCWS review with a non-Cobb Fire project. If the address is not in the CCWS service area, we will have no further involvement.
