Today’s LOS system includes multi-stage turbine pumps, dicyclopentadiene (DCPD), and ProSTEP polypropylene tanks, passively self-cleaning filters, plug-and-play electrical and control connections, and remote monitoring capabilities.

This presentation explores Combined Treatment and Dispersal (CTD) systems—passive technologies that deliver NSF/ANSI Standard 40 effluent without control panels, air pumps, with minimal maintenance.

This presentation will explore how collection, treatment, dispersal, and even operation and maintenance share common principles across centralized and decentralized approaches. We’ll dive into real-world examples of large-scale decentralized systems handling daily flows once thought achievable only through centralized infrastructure.

This presentation will help designers, engineers, and contractors be able to recognize and respond properly for an improved system design, installation efficiency and how best to cover their liabilities.

This presentation advocates the mandatory implementation of secondary safety lids—internal barriers designed to prevent accidental entry into septic tanks, even if the primary lid is dislodged or removed.
