Vidler Water Company, Inc.

Vidler Water Company, Inc. ("Vidler") is a private-sector water resource company focused on the development of reliable water supplies in geographic areas lacking available water resources. We provide water development solutions for end users by identifying, acquiring and developing water rights, often within fragmented agricultural markets, and over time converting these water rights to higher valued municipal and industrial uses.

Vidler has aggregated expertise and fostered a work environment that is inclusive of many professional disciplines which stimulates rigorous and innovative problem solving in the water resource area.

History

The parent company of Vidler Water is D.R. Horton (NYSE: DHI). Vidler made its first water resource investment in 1995 when it acquired Vidler Water Tunnel which owned a water tunnel and associated water rights in Colorado. Vidler continued to make additional investments in water resources and water expertise with several strategic hires in the late 90’s. Vidler's technical depth includes expertise in the areas of geology, hydrology, hydrogeology, environmental permitting, project engineering, water rights and governmental relations.

Over the years Vidler has expanded its geographic presence beyond Colorado and has developed expertise, relationships and successful projects in Arizona, California, Idaho, Nevada, New Mexico, and Utah. Projects of note include the recharge project in Harquahala Valley, Arizona, and two major pipelines in northern Nevada.

In 1996 Vidler purchased land in Harquahala Valley and after just two years of permitting and construction, started storing Excess Colorado Water via the Central Arizona Project. The recharge project was expanded multiple times and over 250,000 acre-feet of long-term storage credits were stored before mothballing the facility in 2013. In addition, Vidler started working on the Fish Springs Ranch Importation Project in Northern Nevada in 2000. After 5 years of pumping and permitting and two years of constructing 35 miles of pipe, the North Valleys area of Reno has enough water to supply 16,000 new homes. Vidler also constructed a 5.5 mile pipeline to connect Carson City and Dayton Utilities in 2009.

In 2022, Vidler merged with D.R. Horton and currently functions as the water resource expert for the nation’s #1 home builder as well as pursuing large infrastructure projects across the southwest.

Our Vision

We believe that our fundamental mission is to help facilitate and support planned economic growth through the development of sustainable and reliable water supplies in geographic areas lacking available water resources.

We believe in saying no to hundreds of projects, so that we can really focus on the few that are truly important and meaningful.

We believe that a deep and broad understanding of the scientific, environmental and regulatory aspects of water resource projects achieved through the expertise and collaboration of our employees differentiates Vidler and allows us to develop innovative solutions in a way that other water resource investors cannot.

Vidler Team

Our Management Team has an average of 20+ years in the water resource business.

We come from different expertise and backgrounds, but we share a common mission to help solve water resources issues by focusing on sustainable and reliable water resource development. Across the Company, Vidler's professionals are focused on working cooperatively with all the various stakeholders in a water project which includes local governments, public agencies, environmental groups and project developers - while at the same time working to provide a fully permitted, sustainable project with a sound financial return to our parent company and its shareholders.

We believe we have the strongest team in the business with expertise in Geology, Hydrology, Environmental Permitting, Water Rights, Project Engineering, Political Affairs, Transaction Structuring and Analysis.
