The City of Olathe requires all Cross Connection systems to have an approved backflow prevention assembly installed to protect the City's water system from contamination.

Additionally, the City requires annual testing of all commercial backflow assemblies, as stated in the City of Olathe Municipal Code (Section 15.08.090) as well as Kansas State Statute 65-163a. Testing of the device(s) must be performed by a certified backflow tester, and results must be submitted online to Aqua Backflow by the test due date.

Frequently Asked Questions

What is backflow?
Backflow is the reversal of flow in a water system from the normal or intended direction of flow, possibly back into the water system. It creates the opportunity for potential contaminants and pollutants from private plumbing connections in your home or business to enter the main water distribution system.

What is cross connection?
Cross Connection control is any connection between the public water supply and a source of contamination or pollution. Potential commercial/residential hazards:

Irrigation systems
Coffee brewers
Fire sprinkler systems
Boilers
Ice machines
Mop sinks
Shampoo sinks
Carbonators

When are backflow tests due?
Commercial assembly tests are due based on their original install date. Aqua Backflow will send out reminder letters prior to due dates.

Why is backflow testing required?
With time and wear, devices can fail and no longer prevent backflow from occurring. By having a backflow preventer installed and tested annually, it helps the City to ensure safe water for our customers by eliminating the potential risk of Cross Connection.

What if I don't use my irrigation system?
The City no longer requires testing of residential irrigation backflow devices, but it is still highly recommended. If you would like to remove or cap off your system permanently, an Individual Trade Permit is required.
