M&M Irrigation & Illumination is a Residential
Sprinkler Evaluation and Education organization.
MMII was formed in 2014 to be an installation, service, and repair company in the irrigation industry. The goal of the company was — and still is —Water Management Through Efficient Irrigation.
In 2015, Michael Mueller, founder and owner of MMII, began to execute residential sprinkler evaluations in Tarrant County and the City of Allen. In the first year, he completed approximately 750 evaluations.
Over time, the company successfully grew. By 2025, MMII was executing approximately 5,000 evaluations per year.
These evaluations are done for the Tarrant Regional Water District (all of Tarrant County), the North Texas Municipal Water District (some, but not all, cities in the district), and the Cities of Allen, Coppell, and Celina.
The company contracts with TX Licensed Irrigators to perform the evaluations. Each evaluator holds a license with the state of Texas to operate in the irrigation industry. These licenses ensure that all evaluators have passed background checks and are legal citizens of the United States.
All evaluators have multiple years of experience in the irrigation industry — most of them in excess of 20 years.
The company is headquartered in Bedford, Texas, and is operated and administered by Michael together with his wife, Mary, and their daughter, Kaci.
