The Delaware SWCD has available for use an inflatable soil tunnel, a tool that helps teach about soil layers, drainage, organisms that live in the soil, soil variance among different land uses, and conservation.

The tunnel, very portable and available to schools for teachers to use, includes a trailer to store and haul the soil tunnel.  All schools inside Delaware County are welcome to use the soil tunnel free of charge.  Educational activities and talking points are included in the soil tunnel lending trailer.  Soil tunnel rental information for organizations outside Delaware County can be discussed by calling (740) 368-1921.


With information on the inside and outside of the Soil Tunnel, your visitors will have plenty of interesting details to explore!

Key Concepts the Soil Tunnel Covers:

  • Soil Layers
  • Soil Drainage
  • Soil Functions
  • Storm Water Pollution Prevention
  • Impacts of Land Use on Soil
  • Soil Organisms
  • Soil Conservation

Don’t have space outside? Maybe it unexpectantly rains on your event day. No problem. Use the Soil Tunnel inside as well.

Special Thanks

This tunnel and storage trailer were made possible through a grant received from the Ohio Environmental Education Fund.
