Sydenham Pit & Pumping Station

The Sydenham Pit and Pumping Station were constructed in 1941 in response to the increased urbanization of the Marrickville area. The pit is lined with sandstones block and forms a critical part of the local storm water infrastructure and it is also of historic, aesthetic and technical significance.

This site provided challenges to traditional inspection techniques as a result of its tall, steep, inaccessible walls and hazardous water. Abyss provided a remote inspection (at up to 20 m of distance), locating and geo-tagging faults and reporting high-definition images of the less than 2 mm wide cracks and other defects, reducing drastically the complexity, safety risk and cost of the inpection operations.
