About Us

Markout Water Supply Corporation was incorporated in Texas on May 31, 1965.  In early 1988, the corporation was granted Non-Profit status by the Internal Revenue Service.  The purpose of the Corporation is to provide continuous and adequate drinking water to every customer who requests service in its CCN (Certificate of Convenience and Necessity).  Markout’s CCN covers approximately 6,000 acres of land in the south Forney area.  Service is obtained by purchasing an equity membership in the system and Markout currently serves nearly 1100 members.  As a water utility, Markout is regulated by the Texas Commission on Environmental Quality (TCEQ) and the Public Utility Commission (PUC).  Markout also holds a membership with the Texas Rural Water Association (TRWA) and is actively involved in the legislative proceedings that affect rural water systems.

The Corporation is governed by a Board of Directors who are all members on our water system that have been elected to serve by the membership.  The Board of Directors meets monthly to discuss the operations of the Corporation.  The annual membership meeting is held in the Month of April each year and all members of the system are encouraged to attend.

For the past several years, the Markout Board of Directors has been seeking ways to reduce water costs, staffing, and operational costs.  We are excited to tell you that the City of Mesquite (Mesquite), working with the City of Forney (Forney), has agreed to acquire Markout Water Supply’s (Markout) service area.

On October 19, 2020, the membership vote regarding merging with the City of Mesquite passed.  Mesquite is now in the process of obtaining approval for the merger from the Public Utility Commission (PUC).  Upon the PUC’s final approval, which may take about 4- 6 months, Markout will be dissolved and all members will become Mesquite’s customers.  Then, according to an agreement already in place between Mesquite and Forney, the cities will work together to physically separate the Grayhawk Subdivision from the distribution system.  This will allow those who live within the Grayhawk Subdivision to receive water, sewer, and sanitation services directly from the City of Forney.


Most of Markout’s geographic area is within Mesquite’s city limits and extraterritorial jurisdiction, so it makes sense for Mesquite to acquire the entire area and then split off what lies in Forney’s city limits and for Forney to serve its own citizens.  By removing Markout’s costs from the delivery of water, the costs will be more manageable for all customers.

Markout Water was needed and filled a great purpose when it was established in 1965 because there were no cities nearby to provide water to those living in the rural area.  Today, the cities are literally within our service area and it no longer makes sense for Markout to exist.

Even though the City of Mesquite will become your new water provider, you won’t see any changes in our procedures for several months.  Your invoices will look the same and are due on the 15th of each month.  Our drop box at the Markout office will continue to be available for you to drop payments and the credit card payment process will remain the same.  Inframark, LLC will continue doing our field work until further notice.
