Not sure when to pressurize an onsite wastewater system or why it may be required by code? This presentation explores shallow systems, optimal soil horizons and the use of pressure distribution. From design to installation we will explore the ins and outs of pressure distribution.

What is process design? How do we decide what unit processes are needed to meet the needed effluent requirements? This webinar will focus on different influent and effluent conditions that need to be considered when designing wastewater processes – from onsite subsurface discharge to point source discharges with tight limits.

Wastewater treatment is partly responsible for the sustainability of humans on Earth without significant numbers of deaths related to diseases that proliferate without proper water sanitation. Historically water treatment has often been seen as a burdensome and costly endeavor.

In most cases perception is reality; such is the case in the wastewater world. The centralized model is perceived to be the Cadillac and the decentralized model is perceived to be the “ugly stepchild”. Upon review of many measurement parameters the decentralized mode of wastewater treatment overturns these common misperceptions.

The objective of this seminar is to increase installers’ awareness of the conditions that exist in the subsurface environment during onsite system construction. The discussion covers geotechnical engineering fundamentals as related to onsite system construction, including soil unit weight, earth pressure, stress on buried structures, and slope stability. Soil stress with depth and the lateral extent of stress in soil will be addressed, as well as the effect of static and dynamic stress on buried structures. Publicly available construction videos will be used as case studies to tie the geotechnical engineering concepts to real-life situations.
