The Trevor basin dry-docks waste water culvert takes the waste water and drainage water from the dry docks next to the canal in the Trevor basin. The dry docks are located behind a swivel bridge and can be flooded and drained as part of the ongoing maintenance and repair of canal boats. The culvert is built into the retaining wall of the Trevor basin docks area and its exit measures 0.5m wide x 0.7m high.
