Hasa's Story

HASA, Inc. is a manufacturing company primarily engaged in the production, sale, and distribution of sodium hypochlorite and related products to the industrial, water treatment and swimming pool markets in the western United States. It has long been dedicated to both the needs of its customers and the impeccable standards of its product.

Don Wilson, the company’s forefather, began his career as a Michigan State University Graduate Chemical Engineer over half a century ago. After a career with Standard Oil Company of Indiana, he moved west and began his affiliation with HASA, Inc.; taking it from a struggling small divergent company, to a specialized, widely recognized industry leader.  HASA, Inc. was established in 1964 and expanded to its present location in 1972. The corporate office, located in Saugus, Southern California, encompasses a manufacturing facility, warehousing and administrative offices.

Mark S. Wilson continued to build upon his father, Don Wilson’s leadership and commitment to excellence. In 1982, Mark expanded the company with a second plant in Eloy, Arizona, and again in 1996 when a third facility in Pittsburg, Northern California was completed.

HASA, Inc. persevered in extending its influence by opening plants in Longview, Washington; Dallas, Texas and most recently, Bryan, TX 77807.

With its well-planned expansion, HASA, Inc., already a recognized leader in the swimming pool and water treatment industries, has been successfully able to service customers throughout California, Nevada, Arizona, New Mexico, Texas, Washington, Oregon, and Idaho.
