Our Story

Bio-Tech (Biological Technology Inc.) has provided exceptional waste treatment services since its founding. We specialize in the restoration and maintenance of waste treatment systems, including septic and aerobic systems, leach field repair, and waste vegetable oil removal. Our services cater to residential, commercial, and industrial clients throughout California.

Originally founded in 1972 as American Technology Inc., we became an independent corporation on May 1, 1992, under the name Bio-Tech. From the beginning, our focus has been to offer high-quality waste treatment solutions to underserved communities in our service areas. Over the years, we have built a reputation for excellence in the industry, with highly trained equipment operators who restore waste treatment systems to optimal functionality.

With over 34 years of experience, we have pioneered leach field remediation, using exclusive equipment to restore leach fields without the need for costly replacements or permits. Our services often become the only viable solution when space or conditions make installing new leach fields impossible.

We understand the importance of effective waste treatment. We ensure that your systems meet or exceed county, state, and federal standards. Timely identification and remediation of sewage or effluent discharge issues prevent violations, fines, and extra costs. Our team is committed to keeping your system running smoothly and in compliance with all regulations.

Our mission is to provide excellence in servicing our clients through clear communication, seven-day-a-week accessibility, and the highest quality of work in all our endeavors. We are a full-service firm that upholds the highest industry standards.
