Ten robotics students from Mishawaka Catholic School might have a solution to groundwater contamination in St. Joseph County.

Some subdivisions have the contamination due to overflowing septic systems.

The students presented their solution to the Country Regional Water and Sewer District board Thursday.

They developed a special sensor system that detects water or sludge levels in the riser lid of the septic tank. A phone app alerts people to clean the tank.

The county set up a 10-member working group to teach people about the problem, but that was put on hold about two years ago.

Engineering professors believe the students have an innovative solution with real-world practicality.

"Over time we thought of ideas and eventually somebody came with this amazing idea of a septic lid that scanned and watched how high your water level was," said Frances Pairitz, Mishawaka Catholic School sixth grader.

The team is competing as part of First Lego League Saturday in Fort Wayne.

They could have a chance at the global competition in the spring.
