Who We Are

African Environmental Development is a relatively small, but specialist company, concentrating on all aspects of water management and hydrology, relating to environmental management, environmental monitoring, environmental engineering and solving of environmental challenges for its clients.

Who Our Clients Are

Our clients vary from mines and industries that may have an impact on the environment or might have other water- of hydrology-related issue, to environmental management consultants that do not have the necessary capacity in water engineering and hydrological aspects, to local authorities, town planners, consulting engineers and private individuals.

Company Background

With the ever-increasing awareness of the environment, in particular, the aquatic environment, and the interaction this aquatic environment has with both people and the business and industrial sector, it became apparent that many businesses or authorities can no longer provide these services to the extent and thoroughness that is required.

For the above reasons, African Environmental Development, based in the Gauteng Province of South Africa, was formed to assist such companies, mines, authorities and individuals that do not wish to employ aquatic or hydrology specialists on a full-time basis, by providing these services on their behalf. African Environmental Development has the capacity to address all aquatic and hydrological issues.

African Environmental Development was formed in 1998 and forms part of a much larger network of environmental management and engineering specialists, covering aspects from the physical environment including hydrogeology, soils and water to the natural environment, such as fauna, flora and ecological systems in general, as well as civil and mechanical aspects such as the modelling of flood lines. In short, African Environmental Development will provide solutions to whatever environmental challenges you may encounter. Our core business remains, however, water management, hydrology and water pollution control.

In addition to management of the aquatic environment, African Environmental Development also specialises in the development of environmental management software, in particular, software to do water and salt balances. Our environmental management software is regarded as being unsurpassed, as we develop industry-specific environmental management modelling programs. Apart from the above, the software we developed to carry out the modelling of flood lines is, as far as we know, not equalled anywhere in South Africa.

African Environmental Development originated out of the mining industry in South Africa, with gold, platinum coal and base-metals mining accounting for a large part of our background. As the ore bodies, which have been mined for well over a century, slowly become depleted, the gold mining industries in Gauteng, Northwest Province and the Free State are gradually winding their operations down, leaving many environmental challenges, and in particular, water-related issues, behind and placing a high demand on our services. The format of the mining industry is also undergoing a metamorphosis. While the traditional large mining corporations are becoming less involved in mining, the smaller-scale, more cost-effective, mines are beginning to replace these on land, previously mined and developed by the larger corporations. This places a very specific, and often, a highly complicated, environmental management responsibility on these new-generation mines. African Environmental Development has ample experience in these types of matters to assist these companies; especially as far as the issues around water pollution and acid mine drainage is concerned.

What We Can Deliver

African Environmental Development can provide the following services to its clients. Adequately qualified specialists will perform all the services listed below, ensuring legal compliance in all respects of the products we deliver:

Water Care

  • Provide a comprehensive aquatic science consultancy service. We have the capacity of addressing any water-related and aquatic environmental issue and to develop solutions to mitigate problems that may be encountered.
  • Provide all monitoring services relating to surface- and groundwater. These include the treatment, discharge and re-use of water and includes the analyses of water, both chemically and biologically (river bio-monitoring), the interpretation of results and the development of management or remediation action plans, where problems are identified. We can carry out monitoring relating to any of the following Dept of Water Affairs-approved aquatic biomonitoring protocols:
  •  SASS (South African Scoring System)
  •  IHAS (Invertebrate Habitat Assessment System)
  •  IHIA (Intermediate Habitat Integrity Assessment)
  • MIRAI (Macro-invertebrate Response Assessment Index)
  • PES (Present Ecological State Class)
  • EIS (Ecological Importance and Sensitivity Category)
  • Auditing of water care installations and the aquatic environment.


  • Hydrological modelling of various return period design storms and determining the flood lines for specific rivers or streams. These flood lines could range from return periods as short as 2 years, through 5, 10, 25 and 50 up to 100-year return periods. The flood lines are made available both electronically in an AutoCAD or Shape file format and through hard copies signed by our engineer.
  • Sizing of culverts and bridges in accordance with specific return period design storms.
  • Auditing of dams to identify and eliminate safety risks.
  • Design of small potable and sewage water care installations.

Software Development

We have the capacity to develop any type of PC-based application, however, we specialise in the development of water management applications. An example of this is the development of Water and Salt Balance software for various industries.
