About Sequoia Pumping
Delivering Trusted Septic Solutions Across the Central Valley Since the 1950s
Our Legacy of Septic Expertise in the Central Valley
Our story began in the 1950s when Donald E. Strickland pioneered the septic industry throughout Fresno’s Central Valley. Through dedication and hard work, he set the foundation for an industry that would serve the area for generations.
In the early 1970s, his son, Donald W. Strickland, continued the tradition of excellence in the septic industry. Over his 42 years of service, he installed thousands of septic systems across the region. Not only did he lead the way in installations, but he also became one of the first pre-cast septic tank manufacturers in the area. His tanks were used by many installers and are still in operation today, a testament to their quality and durability.
By the 1990s, the third generation of the Strickland family—Marc, Kelly, and Michael Strickland—joined the industry, carrying forward the family’s legacy. Having played a vital role in manufacturing, installing, and maintaining septic systems, they bolstered the company’s offerings by adding the area’s largest trucks, which opened new doors to help customers of all sizes, including commercial and industrial clients with their pumping needs.
In the Fall of 2024, Micah Bongberg joined the team and, today, we continue to serve customers across the Central Valley, providing expert septic tank pumping for customers of all sizes, advice on septic system repairs and installations, and septic system inspections. We’re proud to still work with many of our original customers, some of whom we’ve partnered with for decades and multiple generations. We also gladly welcome new customers with whom we hope to build long-lasting relationships well into the future to benefit future generations.
With decades of experience and a deep-rooted connection to our community, we remain committed to delivering reliable, professional, and trusted service for all your septic needs. If you think we can help in any way, don’t hesitate to give us a call at (559) 233-2400.
From installing thousands of septic systems in the 1970s under Donald W. Strickland to expanding our capabilities in the 1990s with Marc, Kelly, and Michael Strickland, we’ve been committed to solving septic challenges for generations. Today, with Micah Bongberg on the team, we continue to provide expert pumping, inspections, and repairs across the Central Valley.
