About Us

Doña Ana Mutual Domestic Water Consumers Association (MDWCA) was founded in 1976, beginning with just 76 connections supplied by a single well. Since then, we’ve grown significantly and now proudly serve:

• Nearly 6,700 water connections

• 1,500 wastewater connections

• Over 15,000 residents

To meet our community’s needs, we operate 12 wells and 7 storage tanks with a combined capacity of 4.5 million gallons, along with a wastewater treatment plant capable of processing 200,000 gallons per day.

Growth Through Mergers

In 2013, our Association expanded rapidly through the merger of three neighboring water systems:

• April 2013: Acquired Fort Selden Water Company, adding service to approximately 400 homes

• December 2013: Acquired Picacho Hills Utility Company, bringing water service to 900 homes and wastewater service to 850 homes

• December 2013: Acquired Fairview Estates Water System, which served 52 homes

• December 2018: Acquired West Mesa Water System, which served 104 homes
