Expected Treatment Level in a Soil Based Treatment System.

SSSA Onsite Wastewater Conference, Innovation in Soil-Based Onsite Wastewater Treatment April 7-8, 2014, Albuquerque, NM Session Selection: Design and Evaluation of Pretreatment Technology Title of Paper: Soil Based Treatment Abstract Infiltrator Systems Inc. has research ongoing; the research should be completed prior to the conference but will not be complete at time of Abstract submittal, September 30, 2013. Until the research is completed it is confidential. I spoke to Mr. Buchanan and he mentioned that it would be acceptable to propose a presentation on the research as this type of problem with timing is common in the research environment. If there is a problem, such as the research is delayed, then as a substitute I have the following abstract that could be utilized: Presentation: Onsite Wastewater Treatment System Drainfield Malfunction: Causes, Investigation, Prevention, and Correction Abstract: The lifespan of an onsite wastewater treatment system drainfield is influenced by numerous factors, including siting, vertical separation distance, maintenance, wastewater flow volume, septic tank volume, as well as other factors. The presentation will review methodologies to diagnose problem site systems. The intention is to have the presentation serve as a learning tool on the potential causes, how to investigate and once the problem is understood then recommending a proper solution. The presentation will review: Malfunction investigation basics, septic tank investigation, function of the tank, drainfield investigation, and malfunction issues and examples.
