Manhole Testers

Cherne Manhole Tester Equipment consists of specialized inflatable sealing systems used by water and wastewater utilities to conduct infiltration and inflow testing on manholes, determining how much groundwater or surface water enters the sewer collection system through damaged joints, covers, or structures. These testing devices help utilities identify problematic manholes that contribute to system overflows, treatment plant overloading, and regulatory compliance issues by isolating individual manholes and measuring water infiltration rates under controlled conditions.
