Springrove dam is located on the Mooi River, about 2 km south east of Rosetta village. The catchment area is 339 km². The dam will have a gross capacity of 139,5 million m³ at full supply level. The dam is classified as a category III dam in terms of the SANCOLD 1991 guidelines and rated as a large dam.
The dam incorporates an earth fill right flank section, a 70m long and 33m high Roller Compacted Concrete (RCC) crest, a RCC non-overspill left flank, an 18m long outlet block on the right flank .
Concrete and RCC is produced on site, using two wet batch plants. The crest section consists of 95600 m³ RCC and the dam wall and affiliated structures, 45000 m³ of conventional concrete.
The RCC mix has a high paste volume and is relatively new technology in South Africa, the mix consisting of 50 kg Cem I cement and 110 kg fly ash per m³. The strength specification of 15 MPa had to be achieved after 365 days.
Although a wet and rainy day, it was an interesting experience to watch RCC being produced and placed.
