Renosterberg Local Municipality lies in the Northern Cape’s Pixley ka Seme District, with its
seat at Petrusville. The 2022 census counted 10,843 people across 5,529.3 km², down slightly
from 10,978 in 2011.
The municipality sits on the Orange River near the Vanderkloof Dam, one of South Africa’s
largest reservoirs, which anchors both irrigation farming and hydropower generation in the area.
The reservoir and hydropower station were built in the 1970s, flooding the valley behind
Petrusville and creating a large recreational lake now used for boating and fishing.
Petrusville and Philipstown are small farming towns typical of the southern Karoo, each
serving as a market centre for surrounding sheep and game farms.

Economy and Local Life
Vanderkloof Dam’s hydropower station and irrigation scheme are central to the local economy,
supporting citrus, lucerne and vegetable farming downstream. Sheep farming continues on the
surrounding Karoo veld, and the dam’s recreational lake draws weekend anglers and boaters,
supporting a small tourism trade around Vanderkloof town.
History
Petrusville was founded in 1876 on the Orange River; Philipstown followed in 1863 as a
Dutch Reformed Church parish town. Vanderkloof grew from the 1970s dam and hydropower
construction project, which flooded part of the valley and displaced some farms. Renosterberg
became a local municipality in December 2000.
