Hello!  I am Julie McWiggins and JM Waterworks. I am a one-woman powerhouse with a 25-year career in the local and regional water industry serving the City of Wenatchee, Greater Wenatchee Valley, and North Central Washington. I founded JM Waterworks in 2012 and am ready to expand back in the Wenatchee Valley to share my knowledge and expertise. 

I am a Washington State Department of Health certified Backflow Assembly Tester (BAT), Cross Connection Control Specialist (CCS), and a Water Distribution Manager IV (WDM4).  

What that means is I test and repair all backflow assemblies, can conduct a cross connection hazard survey for your water system, or even run your small water system as a certified operator. I am proud to be a L & I registered contractor:  licensed, bonded, and insured.

I service all backflow assemblies in the following water systems: Wenatchee, East Wenatchee, Cashmere, Dryden, Peshastin, Leavenworth, Entiat, Chelan, Manson, Rock Island, Crescent Bar, Quincy, Chelan County, Douglas County, and Grant County.

I am dedicated to what I know and have a deep commitment to safe drinking water, customer service, and the relationships I build on a day-to-day basis.  I would love to meet you or see you again!
