Whether the challenge is finding and implementing complex and unique engineering solutions, successfully completing a wide range of construction projects quickly and expertly, working tirelessly with local communities close to where the contracts are taking place or fastidiously instituting practices for the protection of the environment, Sanyati Construction, a JSE-listed construction company, has developed a reputation with colleagues and clients alike for doing things with a hefty dose of excellence.
The paper refers to the increased costs of construction materials and to the consequent need for improved understanding of material properties in order to make the most economic use of available materials. Developments in the structural design of pavements, particularly the effects of temperature and the sensitivity of design to certain input data, are discussed.
This article explains the thinking and planning of the Department of Water and Environmental Affairs (DWEA) (formerly the Department of Water Affairs and Forestry), and how it seeks to meet its responsibility to reconcile growing water needs from a limited supply, now and in the future.
The purpose of the Large Bulk Water Supply Reconciliation Strategy Study for the Vaal River System Study is to develop a strategy for meeting the growing water requirements of the industrial and urban sectors that are served by the Integrated Vaal River System (IVRS).
The Crocodile (West) River catchment area is one of the most developed river catchments in the country. It is characterised by the sprawling urban and industrial areas of northern Johannesburg and Pretoria, extensive irrigation downstream of the Hartbeespoort Dam and large mining developments north of the Magaliesberg. As a result, the Crocodile River is one of the rivers in the country that has been most influenced by human activities, and one for which more specific management strategies are of paramount importance.
The water requirements of the KwaZulu-Natal (KZN) metropolitan areas have been growing rapidly as a result of the expanding economy, urbanisation, several large new infrastructure projects and a general improvement in the existing water supply services. These trends are expected to continue in future and to deal with this situation the Department of Water and Environmental Affairs (DWEA , formerly DWAF), in collaboration with all major water services organisations, has developed strategies on how to meet future water needs up to 2030.
The Lesotho Highlands Water Project (LHWP) Treaty, signed in October 1986, envisaged the development of the project in a number of phases to transfer up to a maximum of 70 m3/s of water from the highlands of Lesotho to the Vaal River System in South Africa, and committed both parties to implement Phase I. Phase I has been implemented and commissioned.
The protection of South Africa's limited water resources is mandatory for ensuring the future sustainability of its people and economy. With a growing population and a thriving economy, abuse of the environment, especially rivers, is a convenient side-effect.
