Preventing Backflow (Cross Connection Control)

In order to ensure safe, clean drinking water for all customers, and in adherence to Kansas regulations, WaterOne is obligated to require the installation of a backflow prevention assembly (BPA) to protect the potable (drinking) water system. Generally, water quality within plumbing systems and water distribution mains is preserved as long as water pressure is maintained. However, certain hydraulic situations may cause the reversal of flow from private plumbing systems into our distribution system, or even from individual plumbing fixtures (like a toilet) into your plumbing system. This is called backflow and it's important to prevent it.

Backflow is prevented by controlling cross connections. A “cross connection” is any actual or potential connection between a public or a consumer's potable water system, and any other non-potable liquid or gas. If backflow occurs and these cross connections are not properly protected, the drinking water within the distribution system, or even your private plumbing system, could be compromised.

We require affected customers to:  

  1. Install a containment backflow prevention assembly (BPA) on water service to:
    • Commercial property
    • Dedicated commercial irrigation lines
    • Fire lines
    • Multi-Family Residential Units four stories and above
    • Single-Family Residential Units with a Dual Water Supply Agreement        
    • Other uses as determined by WaterOne
  2. Install isolation BPAs as required by the Plumbing Code and WaterOne for the protection of the customer's plumbing system
  3. Test containment and isolation backflow prevention assemblies using a certified tester:     
    • After initial installation
    • Annually thereafter
  4. Submit completed test reports to WaterOne

Staff reviews plumbing plans for the protection of the distribution system and the customer's plumbing system.

It is at the sole discretion of WaterOne’s staff to suspend water service if the premises poses a health risk to the public water supply. 

Annual test reports should be submitted via the online form whenever possible. Failure to submit using the online form may result in a delay in processing. Please see our FAQ Document for using the online form for automated processing. New/Removed/Replaced test reports, or Fire Flush only test reports, must be submitted using the old form, and may be e-mailed (preferred) or faxed to Cross-Connection Control:

Fax:    913/895-1822
