All public sanitary sewers must be approved and inspected by PCWASA officials. An inspection of sewer, which will include video inspection and an air pressure test and mandrel, will be scheduled for all projects requiring an extension to the public gravity sewer system. Commercial inspections will be scheduled as needed for tap inspections. All inspections will be scheduled at least 24 hours in advance. However, the Authority reserves the right to perform random on-site inspections during the construction process.
