Inspection and Relocation of Pressure Sewer in 2023 and 2024

In 2023 and 2024, Varpaisjärvi Earthworks and Water Technology commissioned several diving inspections from Unwa Oy. The inspections focused on a pressure sewer and its location on the shoreline of Ainola in Korpilahti.

In 2023, one of our tasks was to install lifting ropes on the old pressure sewer, enabling the contractor to lift it up and perform the necessary installation work.

We also carried out diving inspections for both the new and old pressure sewers. A detailed inspection report was provided to the client after each check.

In 2024, Unwa Oy divers conducted a location survey for the pressure sewer pipeline. An extension joint was installed in the pipeline, followed by another diving inspection.
