Irrigation + Lighting Specialists, serving the San Francisco Peninsula for over 40 years.

The San Francisco Peninsula has a history of beautiful landscapes combined with the challenge of responsible water usage. Randy Thomas and Tom Woodhams co-founded 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. Previously a long-time employee, Robert Porterfield now serves as owner of Peninsula Irrigation Co. Alongside he and his wife, a small team of dedicated employees continue our legacy of expertise, quality and work ethic that has defined us for over 40 years.
