DN500mm Asbestos Cement Trenchless Rehabilitation Including 8 Bends, Total 173 Meters - South Africa
The client, Sun City Resort in the Bojanala Region of North West province of SA, used the Lock Down (announced by our {president Cyril Ramaphosa to begin on March 26th 2020,) as the perfect time to conduct routine maintenance to the hotels, casino and water parks. One such project that was tackled was the main water supply pipeline at the Valley of the Waves due to the high level of water loss (1000’s of litres weekly) that was taking place.
After an investigation using CCTV Inspection, Pipeline Location, pressure testing and other condition assessments systems, Orsco (Pty) Ltd identified many misplaced joints, broken and jammed butterfly values, numerous pinhole leaks and not pipe material degradation due to age (the pipe being more than 28 years old,). The entire pipeline was found to be in very poor overall condition.
After survey results were analysed by our surveying technicians & lining rehabilitation engineer Mr Alaster Goyns recommendations were made and forwarded to Mr Bret Hoppe & Mr Thulani Malinga of Sun City that rehabilitation of the DN500 was necessary.
