How to Take Your Class on a Field Trip of City Sewers Without Risking Their Health

Teaching a class of high schoolers about civil and structural engineering can be challenging at times. There are only so many places you can go for field trips that will be safe for the youngsters to go. City sewers combine both structural and civil engineering, but unfortunately, trips into city sewer systems pose major health risks for the kids. It takes a little creative thinking, but this field trip is still possible when you use a sewer camera rental. Here is how.

First, Rent the Sewer Cameras

If you can rent more than one camera, that is a good option because it will be easier for students to learn if they can break into smaller groups to use the cameras. If not, you will all have to take turns using and viewing the camera. Be sure you know how to use one before showing your students how to use it as a broken rental means that the school may have to buy it.

Second, Locate Several of the Nearest Drainage Sewers

The biggest hazard with taking a "walk" through the sewers is the sewage and the gases, namely ammonia and methane. The camera(s) lets you circumvent the gases and still see and map out the city sewer system below your feet. Find the nearest drainage sewer openings along the sidewalks, preferably on streets that are not very busy. These are the "doors" into the sewer system that your students will "walk" through with the cameras and experience a bird's eye view.

Third, Show Your Students How to Use the Camera(s) and What You Expect From the Project

Show the teens how to use the sewer camera and how to maneuver it through the drains and into the sewers themselves. One or two students will have to feed the camera line while another student calls out which direction to feed it. They are learning cooperation skills while they explore.

Then instruct them as to what the project is meant to do. For example, studying civil and structural engineering may entail running the camera out several yards into the sewer system and creating a map of the structures the camera encounters. Encourage the students to be as accurate with details as they can, and include anything unusual they see while they explore the sewers with the camera(s). Use the maps the students draw against any city planning maps in the courthouse to see how closely and accurately the students came to mapping out a section of sewer.
