John Cascio is the President of John C Cascio Septic Service, bringing decades of experience, technical expertise, and scientific knowledge to the field of onsite sewage treatment and disposal systems. Since entering the industry in 1998, John has built a career defined by precision, problem-solving, and a deep understanding of environmental health.
John began his career on August 31, 1998, immediately after graduating from Florida State University with a Bachelor of Science in Biological Sciences — a scientific foundation that shapes how he approaches soil composition, environmental factors, and the biological processes behind wastewater treatment.
Graduated from Florida State University, building the scientific foundation for his career.
Certified the same year he entered the septic industry on August 31, 1998.
Earned licensure to design and install onsite sewage treatment systems.
Achieved the field's highest distinction after two decades of hands-on experience.
John is proficient in every aspect of onsite sewage treatment and disposal, with particular strength in system design, soil analysis, and navigating complex permitting — including variance processes when standard solutions won't work.
Designs systems that meet regulatory standards while performing reliably over time.
Evaluates soil characteristics and site limitations to guide every design decision.
Navigates variance processes to develop even the most challenging properties.
Manages technically demanding, large-scale installations from start to finish.
A recent highlight of John's work includes the installation of a 22,000-square-foot drip irrigation drainfield for a package plant serving a school — a project that demanded careful planning, precise execution, and a thorough understanding of both system design and site conditions. John also consistently achieves permit approvals for advanced treatment systems on properties where others encounter obstacles.
John is the father of three children who mean the world to him. He spends much of his free time creating memories with them, from amusement park trips to family cruises.
A passionate surfer, John has recently taken up riding the FlowRider — combining his love of the water with a new challenge, and reflecting the same energetic approach he brings to his work.
