We are South-Australian owned and operated and we service all parts of metropolitan Adelaide, rural and regional areas within SA and the Northern Territory. Ri-Industries was the first South Australian company to combine the manufacture, delivery and placement of septic tanks. With engineering experience that spans over 60 years, we have developed a number of associated products to deal with sewage and waste, most notably our Ri-Treat system. Our unique design has become a leader in South Australia for the management and treatment of waste water.
