Workers laying stormwater pipes in the Whanganui suburb of Castlecliff have hit a 113-year-old culvert - built to accommodate the city’s now-defunct tram line.
A report from Whanganui’s Archaeology North said a tramline from Gonville to Castlecliff was built in 1911.
At the time, the land surrounding the culvert was owned by the Matipo Land Company.
The company named streets in the area after native trees, such as Raupo, Kowhai and Matipo.
When the culvert was opened by Loaders contractors this week, a plumber’s box belonging to A.E Falconer and Co Ltd was found inside.
The report said the box was unlikely to be associated with the construction of the culvert and was probably deposited in the drain after its construction.
A Whanganui Chronicle article from 1950 said when the service started running, the total length of track “was only 4 1/2 miles [7.24km]”.
“With the completion of the full programme for serving Wanganui and suburbs the length of track increased to 17 miles [27.3km], and from an original cost of £45,000 the capital cost increased to more than £250,000,” the article said.
Whanganui District Council Three Waters project engineer Nikki Ni said the discovery of the culvert would not cause any delays to the project.
Last year, contractors installing a wastewater main on Nixon St in Whanganui East were slowed by 4575-year-old tōtara timber, which was discovered at a depth of about 8m. The timber continuously jammed the boring machine used for the project.
Ni said she had worked on four stormwater projects for the council over the past five years and this was the first time she had needed to call Archeology North.
“The contractor found the culvert on Monday [May 6] at around 4pm and Michael [Taylor] and Hamish [Crimp] from Archaeology North were on-site first thing on Tuesday morning,” she said.
“When you’re doing construction work there is always a risk that you’ll find something, but [the archaeology work] only took two or three hours.
“The culvert crosses our new stormwater alignment so we’ve had to cut through it. We’ve followed all the right procedures.”
