Please be careful as there is a bit of rubbish and debris in this area and on a second visit I made to check the coordinates I even found an old plastic drink bottle with a syringe in it. I removed it from the area because it was safely contained in the bottle, but if you find any more do not pick up with your bare hands.
The Lane is is a popular access route between Sydenham Station, The Marrickville Metro Shoping Centre, and the local businesses in this mostly industrial part of Marrickville. There are also a lot of stray cats in the area.
The cache is a small bulbous screwtop container.
The other feature here is a huge storm water catchment reservoir which services the local area. The following excerpt is from the Sydney Water website.
'The Sydenham Pit and Pumping Station is of historic, aesthetic and technical significance. Historically, it is the first such infrastructure built in the Sydney Water system and is an intact and major component of the Marrickville low level stormwater drainage infrastructure that was built in response to increasing urban expansion since the 1870s in an area prone to flooding. Its large scale and labour intensive construction method of excavating the pit reflects the abundance of labour during the Great Depression and the type of public works undertaken to provide relief work for the unemployed. Aesthetically, the use of pitched dry packed ashlar sandstone walls to line the sides of the pit provides a pleasantly textured and coloured finish to the pit. It is a major landmark and dramatic component of the industrial landscape of Sydenham, particularly as viewed from the railway. The pumping station is a very good example of a utilitarian building displaying inter-war Mediterranean style architectural details. Technically, the pumping plant contains good working examples of 1930s pumps, particularly three Metropolitan Vickers pumps, and its original electrical mains equipment has been preserved in situ during upgrading in c.1992.'
