Carefree – Liberty Utilities (Black Mountain Sewer) Corp. (Liberty Utilities) has owned and operated the Carefree Wastewater Treatment Plant (Carefree WWTP) located in the Boulders for more than 40 years,and has provided safe and reliable wastewater service to customers including the Town of Carefree and Boulders Resort residents. On Friday, November 30th, Liberty Utilities ceased the flows of wastewater going into the Carefree WWTP and instead began conveying its wastewater flows through an interconnection with the City of Scottsdale to the City of Scottsdale Water Campus.
In 2007, Liberty Utilities, the Boulders Homeowners Association, (BHOA)and the Town of Carefree entered into a series of discussions about closing the Carefree WWTP located in the Boulders. In late 2010, the Arizona Corporation Commission (ACC) ordered the closure of the Carefree WWTP to address concerns expressed by the customers within the area of the Carefree WWTP. While Liberty Utilities operated the Carefree WWTP within compliance of applicable regulations, Liberty Utilities partnered with concerned stakeholders and agreed to close the plant as requested by the Town of Carefree, the BHOA and Liberty Utilities’ customers.
