Grootdraai Dam is a composite structure comprising a central concrete gravity section 360m long and two earthfill flanks giving a total crest length of 2 180m and a maximum wall height of 42m above lowest foundation level. The dam was completed in 1982 and was built primarily to support the water needs of the SASOL I, II and III coal to petrol plants at Secunda, ESKOM's, Tutuka Power Station as well as the Matla, Duvha, Kendal and Kriel power stations located on the coal fields in the adjacent Olifants River basin.
