This is a short section of the 24 inch (600mm) cast iron main pipe laid from the reservoir down the valley of Glen Creek and thence via Eden Street to Oamaru township. The pipe is in remarkably good condition. It is about 28mm thick and was cast in Christchurch by Anderson's Engineering a pioneer foundry which had a reputation for quality innovative work.
Pipes of 24 inch (600mm) 18inch (450mm) and 300 mm were made for the project and later some 250mm pipes were laid.
In 2011 a section of pipe was exposed and damaged (a fitting broken off) during road works in Thames Street. The pipe was a bare 500mm below road level and most of the network was similarly only buried at a shallow depth, heavy traffic on the roadways having not been predicted in 1880.
