An economy and ecosystem symbiosis: barrier systems for water conservation and pollution control

Read abstract
An awareness of the rate at which water resource development took place in South Africa being supply driven until relatively recent times leads to an appreciation of the changing philosophy in respect of water conservation and pollution control, as well as essential amendment to principles and procedures. Reconciling water demand and supply in catchments requires concurrent consideration of available water quantity and quality. This stimulates the need for change in the way we view water uses and brings about business opportunities in the sector. The review of infrastructure designs in support of water use and mining applications for industrial and mining waste has developed and transformed along with improved technology and changes in legislation since 1994 in South Africa. A containment barrier system comprises of both filter protected drains and low permeability liners which are visible in the short term until covered. They are required to perform effectively after initial use and are often inaccessible for the operating period and subsequent service life of decades or even centuries. This paper presents a regulators perspective of commonly repeated deviation from accepted norms and standards in the engineering profession as applied to pollution control facilities. Emphasis is placed on the standards of today with experience reflecting on the past five years of design reviews, leading to conclusions and recommendations for facility owners and practitioners. Examples of procedure, mechanisms, performance, specifications and socio-economic benefits are addressed. It is postulated that in the near future many mining and industrial developers will choose to improve containment standards of barrier systems as a component of reengineering water demands and for economic advantage while embracing contributions from ecosystem services.

Kelvin is the Chief Engineer: Integrated Development in the Department of Water and Sanitation, RSA. He has over 35 years experience which extends from large storage dam developments, through associated civil, environmental and mining infrastructure, to waste management technology. Having specialised in the field of fluid flow through natural materials and geosynthetics, he is a member of SANCOLD, the International Geosynthetics Society, and SA Institute of Civil Engineers; and formerly the Chairman of the IGS Technical Committee on Filters (2014 – 2018). He leads the Department of Water and Sanitation engineering services review panel which advises the Authorities on pollution control and other resource protection works for licensing purposes.

Conference Co-Chairs

Professor Andy Fourie
Professor of Civil and Mining Engineering
The University of Western Australia, Australia

Andy is a Professor in the School of Civil, Environmental and Mining Engineering at The University of Western Australia in Perth.
He has Bachelors and Masters degrees from the University of the Witwatersrand in South Africa, and a PhD from Imperial College, University of London. He has worked at the University of Queensland, the University of Witwatersrand and has been a visiting professor at the University of Alberta, the Catholic University of Valparaiso in Chile and the University of Colorado in Boulder. His research is in the field of mitigating the impact of mining and municipal solid waste disposal. Outcomes from his research have been incorporated in changes to environmental legislation in South Africa. He contributed to a series of Guidelines for managing mine tailings in Australia, as well as developing a document for the International Atomic Energy Association on barrier systems for retaining uranium mining waste.

Dr Angus Paterson
Managing Director
Paterson & Cooke Consulting Engineers (Pty) Ltd, South Africa

Angus is the managing director of the Cape Town office of Paterson & Cooke, having founded the company together with Dr. Robert Cooke in 1991. The company now has offices in South Africa, USA, Canada, UK, Chile and Australia.
Angus completed his Civil Engineering degree at the University of Cape Town in 1984 and continued post graduate studies, completing an MSc in 1986 and a PhD in 1991. His research work focused on the flow behaviour of high concentration backfill slurry pipelines.
Angus has been directly involved in analysis and design of slurry transport systems since 1987 and has worked on slurry pipeline projects throughout the world. These include long distance slurry pipelines, underground paste and backfill distribution systems and numerous conventional, thickened and paste tailings disposal systems.
