Click on the links below for a list of contractors in each county that are certified to install or maintain the NuWater BNR Series systems.  Please note that each provider needs to also be licensed by the county in which the work will be completed. 

If installation, inspections and/or maintenance services are provided by an uncertified contractor, the warranty will be null and void. 

Confirmation that an installer, inspector or O&M provider is trained & certified by NuWater and licensed by your county can be obtained by contacting your county's environmental health department.

If unable to determine which providers are certified through your county health department, you may request by email information on your local NuWater Certified Providers.  Please email to This email address is being protected from spambots. You need JavaScript enabled to view it.
