Onsite Septic

CSI manufactures Flowtite® fiberglass tanks for both aerobic and anaerobic septic applications. Our watertight tanks are a cost-effective, long-term solution for private homes, commercial developments, industrial and municipal applications. Government and state regulation of septic storage is changing to help reduce infiltration and exfiltration contamination. Flowtite fiberglass septic tanks, also referred to as cisterns, eliminate leakage problems inherent in concrete septic systems. Our tanks are engineered to meet and exceed current requirements and standards. We offer IAPMO Z1000 approved tanks in various sizes up to 12’ diameter including fiberglass baffles and other accessories.


EPA statistics show that onsite septic systems serve approximately 25% of the entire US population and account for almost 40% of new residential development septic needs. The cost of expanding municipality services begins to out pace profitability which leads to planned developments relying on onsite septic designs for proper wastewater management.
