Branxholme is a rural locality in Southland District, on the Ōreti River to the north-west of Invercargill. It sits near the city, not inside Invercargill City. This is farming country rather than a township, and it has no verified village centre of its own.
The name is widely known because the Branxholme Water Treatment Plant, on the river, supplies drinking water to Invercargill and Bluff. The same riverbank is part of Southland railway history: obsolete steam locomotives were once tipped here to hold the line against erosion.

About Branxholme
Southland District Council lists Branxholme among the communities of the Ōreti Ward and the Ōreti Community Board. In published lists of the district it sits with the Wallacetown group of localities, on the plains north-west of Invercargill.
Māori-language reference works describe it as a nohanga, a small settlement, in the Murihiku district. No separate Māori name for the locality has been confirmed.
The ground here is the Southland Plains: river gravel and silt washed down over a long time, with the Ōreti River as the defining feature. The locality is working farmland. There is no verified main street, shopping strip or school inside Branxholme itself. Everyday errands mean a drive to Invercargill.
What makes the place matter beyond its own paddocks is water. Invercargill City Council draws city supply from the Ōreti River at the Branxholme Water Treatment Plant and sends it south to Invercargill and Bluff. The plant is council infrastructure on the outskirts of the city, not a park or a visitor centre.
The river crossing is also a railway place. The line west of Invercargill, once the Wairio Branch and now the Ohai Industrial Line, meets the Ōreti River at Branxholme. Soft ground and an awkward bend made the embankment hard to hold, which is why the bank became both a waterworks site and a locomotive dump.
Water from the Ōreti
The treatment plant takes source water from the Ōreti River. From there, a trunk pipeline runs to the water tower in Gala Street, Invercargill, and the network serves both Invercargill and Bluff. The pipeline this main replaced was installed in 1958.
Invercargill City Council has since replaced almost 11 kilometres of that aged main with a new line, which the council describes as fully operational, with an expected life of more than 100 years.
The plant and the pipeline are working assets. They are not set up for casual visits. Fenced water-supply land, riverbanks and construction corridors should be left alone. If you are passing on a public road, the interest is in understanding where the city’s water starts, not in entering the site.
Railway History on the Riverbank
The loose rock and mud at the Ōreti crossing gave the railway an unstable formation. Rock and debris tipped in to steady the line did not stay put after heavy rain and floods.
In 1927, when scrap steel was uneconomic, New Zealand Railways sent the hulks of fifteen stripped steam locomotives to Branxholme and tipped them into the river as a bulwark. The dump is on the eastern bank, just north of the line, where the river runs beside the railway in a bend before passing under the bridge.
The best-known recovery is Rogers K 88 Washington, dumped in 1927, lifted in 1974 with help from the Southland Vintage Car Club, New Zealand Railways and Invercargill City Council, and returned to service in 1982 at the Plains Vintage Railway near Ashburton.
Other hulks and parts have been salvaged in later years for preservation or spare parts. The dumpsite sits with the city waterworks. It is not a staffed museum, the bank can be muddy and unstable, and remaining material should not be disturbed.
Getting Around
Branxholme is a drive-to locality. There is no confirmed passenger train stop, and no regular town bus has been verified for the settlement itself. Roads are rural, and the landmark most drivers will recognise on a map is the river crossing of the Ohai Industrial Line, together with the water treatment plant.
This is not a walking or swimming destination with confirmed public facilities. No official swim site, track or reserve has been verified here. The river is a working water source and a flood-prone bank, so treat it as private and operational land unless you are on a clearly public road.
