ELECTRICAL AND ELECTRONIC

1.1   Specialized Electrical and Electronic Expertise
The specialized experience and expertise as achieved with the completion of many dams, pumping stations, 
water care works as well as water treatment works are applied. The company Buro Tech Consulting Engineers has
an intimate experience with the rather specialized control of water related and treatment plants. The specific
experience of personnel in electrical and electronic engineering can be summarized as follows:

  • 40 Pump stations with largest capacity:                          24m³/sec
  • 10 Sewerage plants with largest capacity:                       20 Meg liter/day
  • 15 Water treatment works with largest capacity:          120 Meg liter/day
  • 4 Dam walls for DWAF:                                             Wolwedans, Inanda, Glen Mellville & Nandoni Dams

It is believed that the experience to date has earned Buro Tech Consulting Engineers the right to be a serious
contender as Electrical Consulting Engineers for the mentioned services. Buro Tech is also proud of the fact that
personnel employed in the Electrical Department of DWA & F forms part of their reference list..

1.2   Energy Effective Design
The electrical installation of every dam will be audited and re-designed where applicable for energy effectiveness
compliance with SANS 204. The optimization of energy consumption thus forms a very important criteria in any
design. The following fields are inter alia addressed:

1.2.1   Selection of Motor/Pump set Combinations - If Applicable
The most efficient pump set combination is selected and running costs are capitalized over a period. Incentives
and penalties are therefore applied as required by DWA & F to motivate suppliers of equipment to make the most
energy efficient selections of equipment.

1.2.2   Electricity Tariff
The existing electricity tariffs will be studied to ensure that the most suitable and lowest tariff is applied by the
electricity provider.

1.2.3   Power Factor Correction - If Applicable
The power factor of all plants is corrected to the most economical factor as required by the electricity tariff. Central
or individual correction studies are performed.

1.2.4   Variable Speed Drives (VSD's) - If Applicable
The application of VSD drives is considered where required for water demand control or process flow
requirements. The cost savings can be significant.

1.3   Process Control, Instrumentation and Automation
The latest technology and best fit for purpose control and automatization philosophies are considered and applied
during the design stage of any project. Final selections are performed in collaboration with the client.

1.4  Electrical Distribution
A proper analysis is carried out for power planning, evaluation and reporting purposes. Multi-level voltage systems
are modeled, load flow analysis, comprehensive fault level studies, voltage and transient motor as well
protection studies are performed

The Following computer aided software design programs are applied:

  • ReticMaster for voltage depression and load flow studies.

The supply authority is consulted to determine the least depressions of voltages on the supply network as well as
to determine the best voltage and substation configurations.

1.5   General Electrical
The electrical designs and layouts will be carried out according to the directives of the Client should it be available.
The Standard specification of the Client will be applied as well as the other documentation as required by the
Client's Electrical Division. Co-ordination will also be done with other divisions such as the Mechanical Division.

Lighting designs is performed with the application of the following software design programs:

  • Relux:              Internal Lighting
  • SABS 098:      Street Lighting
