CMA TO HOLD ONE-DAY SEMINARS ON THE DESIGN OF CONCRETE OUTFALL SEWERS:
Article Date: 24 February 2009
 The Concrete Manufacturers Association (CMA) will be staging a series of seminars during May on the design of concrete outfall sewers at four different venues across the country.
Dates and venues are as follows:
• May 14th at BYTES Conference Centre, Midrand
• May 21st at HERMS Conference Centre in Port Elizabeth
• May 26th at University of Stellenbosch Business School, Bellville, W Cape
• May 28th at Assagay Hotel in Assagay KwaZulu-Natal.
The seminars will be presented by well-known pipe expert, Alaster Goyns. A Pr Eng with a Bsc Civil Eng and an MBL, Goyns spent 21 years in the concrete pipe industry before starting his own consultancy some 10 years ago, specialising in gravity pipeline and trenchless rehabilitation.
Goyns has written a several papers on sewer corrosion, having presented them both locally and internationally.
Since 1999 he has managed the Virginia Sewer corrosion project on behalf of the concrete pipe industry. He was a founder member of the sewer study group initiated in 1987 that motivated the inclusion of this experimental section during the construction of this sewer.
The implementation of this project and monitoring over the first five years was undertaken by the CSIR. Subsequent phases have been monitored by the concrete pipe industry in conjunction with the University of Cape Town. A series of pipe materials have been evaluated over 14 years in this live experiment under extremely aggressive conditions and the results have been used in a design manual for the prediction and control of corrosion in sewers. Copies of the manual will be provided at the seminar.
Anyone wishing to attend one of the seminars, which are free and qualify for CPD points, should contact Pam at the CMA on main.cma@gmail.com or on Tel: 011 805-6742.
