OLD CITY MAINS
BIG FUTURE PROBLEM
A short section of a 70-year-old underground water main, brought into the City Engineer's office yesterday, shows remarkable corrosion. Originally it was five inches in diameter outside, and five-eighths of an inch thick, but external oxidisation and internal rusting, with occasional borings to clean out the rust, have thinned the metal to little more than a quarter of an inch in thickness. Here and there rust has penetrated from the outside, and at such spots there are remarkable collections of nodules inside, some of them l£in thick, ugly excrescences like some fungoid growth.
Underground seepage is common in many places in Wellington. The piece of pipe was cut out in Manners Street. It is certainly one of the oldest city mains, but its condition raises speculation as to how later laid mains are standing up to the conditions. The City Council has set aside a sum for renewal of mains, and this work will have to be tackled as soon as labour and material are available. It will be one of the big post-war jobs.
