The San Francisco Peninsula has a history of beautiful landscapes combined with the challenge of responsible water usage. Randy Thomas started Peninsula Irrigation Co. in 1978 and developed a focus on the unique needs of our area. Since then we continue to specialize in Irrigation and Lighting, while embodying the values of high-quality work and great customer relationships that are part of our legacy.

Today we still operate as a small family-run company. Randy’s son Nate along with his wife Joanna work with a small team of dedicated employees to continue our legacy of expertise, quality and work ethic that has defined us for over 40 years.
