Analyzing Wastewater Treatment Systems Serving Residential and
Commercial Facilities for High Strength and Hydraulic LoadingMountain Horticultural Crops Research and Extension Center
Fletcher, NC August 20-21, 2008Sponsored by
NC State University
and the
Consortium of Institutes for Decentralized Wastewater Treatment (CIDWT)About the Course
There are many reasons why an onsite wastewater treatment system may not effectively accept and treat wastewater. When troubleshooting systems that are not functioning properly, it is critical to identify and fully understand the potential reasons for the malfunction. While wastewater strength may not be the cause for malfunction, it can certainly compound the problem and must be addressed in crafting the solution. This workshop is designed to provide specific guidance on evaluating wastewater treatment systems and wastewater sources to determine if organic and hydraulic loading is above what is expected from typical residential sources. The designer and service provider must consider not only the wastewater source, but also the treatment capability of the technologies and the long-term operation and maintenance needs of the system in order to ensure effective onsite wastewater treatment.The format of this program is lecture-style with PowerPoint slides to aid in discussion. Lectures focus on describing items that must be verified and recorded for a variety of facilities. The accompanying system analysis forms provide a detailed guide for reviewing current management practices being followed within various types of facilities.
Program Faculty
Dr. Bruce J. Lesikar serves as Associate Department Head, Professor, and Extension Program leader in the Biological and Agricultural Engineering Department at Texas AgriLife Extension Service. Bruce conducts research into the effectiveness of on-site wastewater treatment systems under various site, soil, and water table conditions; evaluates various innovative/alternative onsite wastewater treatment systems; evaluates water conservation practices; and develops informational resources describing water conservation, treatment, and reuse systems.William L. Stuth (Bill) has worked in the on-site waste industry since 1955, establishing Stuth Company, Inc. in 1962. He designed, installed and performed troubleshooting on on-site systems for 46 years, specializing in commercial high strength waste for the past 17 years. In 1985 Bill established Aqua Test. Inc., a wastewater management firm with a DOE accredited wastewater-testing laboratory. He developed and patented the Nibbler® wastewater treatment system used to treat high-strength commercial greywater, and also the Nibbler jr., and "Flo Filter". Bill works with engineering firms across the nation designing repairs. Because of the success of these repairs, companies ask for assistance when designing onsite systems with flows up to 50,000 GPD for new construction. Bill has traveled the United States extensively consulting and troubleshooting.
Dr. Dave Lindbo is an Associate Professor and Extension Specialist of nonagricultural soil science in the Soil Science Department, North Carolina State University. David has over 14 years experience conducting research on soil morphology and environmental relationships in several states He has developed many training courses in basic soil science, soil morphology hydric soils, and onsite wastewater issues for extension agents and consultants. His research interests include soil morphology-landscape hydrology-vegetation relationships, onsite wastewater systems, NPS water quality issues related to septic systems, and soil variability. David is a North Carolina Licensed Soil Scientist and an ARCPACS Certified Professional Soil Scientist.
Nancy Deal is an Extension Associate for NC State University Soil Science Extension and an adjunct lecturer for East Carolina University with 18 years of experience in environmental health with an emphasis in onsite wastewater treatment. She travels the state and the country developing and delivering training, education and technical assistance to homeowners, small communities, onsite professionals and local units of government regarding decentralized wastewater treatment. Ms. Deal is also engaged in research on system malfunction as related to best management practices (BMPs). Projects include soil and site evaluation and the use of water treatment devices in conjunction with decentralized systems.
