SETLL - Soil Environment Technology Learning Lab

Ohio State University Extension
Reuse of Reclaimed Wastewater Through Irrigation
To meet the goal to eliminate the discharge of pollutants to Ohio's streams and lakes, we study year-round wastewater reuse. Using wastewater nutrients to grow plants prevents water pollution. New disinfection systems are studied to protect the public health from wastewater pathogens.
Site and Soil Evaluation
Workshops and field days are held to teach installers, inspectors and designers of onsite sewage treatment systems what they need to know about soils. Extension bulletins are also available on soil suitability and evaluation.
Wastewater treatment systems in a Chinese village
Le Jia Cun is a small village in Shandong Province, China. Through a collaboration between OSU SETLL and the Shandong Academy of Agricultural Sciences, the village constructed a a simple, low cost sand bioreactor system.
Soil Environment Technology Learning Lab
Created in 2000, Drs. Karen Mancl and Brian Slater have offered educational programs and conducted research in onsite wastewater treatment systems for Ohio.
Protecting Ohio's streams and lakes using low-cost technology
The wastewater treatment plant at a turkey slaughterhouse meets all the discharge requirements to protect the Whitewater River, an important recreational waterway. The 200,000 gpd sand bioreactor treatment system saved the company $10 million and preserved over 100 jobs.

  1. Sand Bioreactors - alternative to a mound or aerobic system

    Jun 10, 2016

    Have a challenging lot and looking for a low-cost, easy to maintain treatment system?  Consider a sand bioreactor.  Buried in the yard, sand bioreactors are low profile and quiet.  The effluent is extremely clean and once disinfected can be discharged to a stream with an NPDES permit or irrigated on the lot.  To find out more read the new fact sheet Sand Bioreactors for Onsite Wastewater Treatment.
