Hidro-Tech was founded by Rudolf Viljoen in the Free State Province in 1986. Initially, the focus of the company was to provide pumping solutions to the Free State mining customers, although a number of mechanical and electrical pumping installations were also undertaken. By 1989, Hidro-Tech Sales and Projects (Pty) Ltd was well established, focussing on sales of pumps as well as contracting, concentrating on water and wastewater pumping stations and pipeline installations.

The company relocated to the Western Cape in 1993, opening a branch office in Bellville. The Cape Town branch concentrated on sales, with a couple of minor mechanical and electrical contracts being completed. In June 1999, the original Hidro-Tech Sales and Projects (Pty) Ltd was unbundled, and Hidro-Tech (Pty) Ltd was formed as a separate entity.

WE OPERATE A FULLY EQUIPPED WORKSHOP led by a qualified foreman with pump fitters and turners.
All repair work is performed in house; we can also attend to On Site repairs when required.
