This presentation will look at some of the commercial offerings of convenience stores and their impact on the wastewater stream

This presentation will review common wastewater characteristics and flow patterns as well as design considerations for different types of commercial facilities.

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.

In this presentation we are going to talk about direct discharge permit limits, the need for disinfection before direct discharge, and the different disinfection technologies that can be used to meet permit requirements.

One of the most critical parts of an onsite wastewater treatment system is the development of a healthy biomat, yet biomat is not something that can be purchased from a distributor. So, what exactly is the biomat and how does it form in a drainfield?
