Churchill County's first water treatment facility, the Sand Creek Water Treatment Plant, began operation in September 2007. The treatment facility was designed to meet water quality standards as required by the Safe Drinking Water Act, and has replaced water systems that were becoming obsolete in several subdivisions, mobile home parks, and commercial businesses along the westward corridor of Highway 50. Sand Creek currently services over 260 homes and businesses, with the ability to expand to 1,000 to 1,500 customers.
In 2005, Churchill County took over ownership and operation of the Pine Grove Wastewater Treatment Facility to accommodate rapid development in the area and prepare for the construction of larger more efficient wastewater treatment facilities. In 2009, the Moody Lane Regional Water Reclamation Facility was completed. This state-of-the-art wastewater treatment plant is the first in Nevada to utilize the revolutionary Membrane Bioreactor (MBR) technology. The Moody Lane Wastewater Treatment Plant is sufficient to meet the demands within the County's service area for 20 to 30 years.
