Talk centred on evaluating Windhoek’s production boreholes water quality set for next week

The Namibia Scientific Society will host a talk from David Silas’ research, titled, Windhoek production boreholes water quality evaluation using Geographic Information System (GIS) Based geostatistical algorithm-the findings, on 6 February at 19:00.

In his talk Silas will emphasise on how, the contemporary threats of climate change have prompted the dependency on production boreholes as a sustainable supply for domestic water in Windhoek, therefore, maintaining the production boreholes water quality is a vital intervention for a city like Windhoek.

His research aims to provide an overview for evaluation of water quality for production boreholes in Windhoek, through applying GIS and geostatistical algorithms, were, the production boreholes water quality parameters namely, chloride, iron, temperature, ph and electrical conductivity were sampled and analysed from existing production boreholes owned by the City of Windhoek.

Silas created maps of each parameter using geostatisical (kriging) approach, which, showed that this method is appropriate for environmental spatial distributed parameters. His study discovered that pro-active measures must be taken into consideration before the water from production boreholes is used for domestic purposes and that water from some production boreholes in certain areas of Windhoek is not safe for consumption due to high temperature causing bacteriological contamination.

David Silas is a GIS analyst at Excel Dynamic Solutions Pty Ltd. He graduated with a Bachelor’s degree in Geo-infromation Science from the Namibia University of Science and Technology (NUST) in 2019. He is a member of Youth Earth Scientist (YES) Network initiated by the Ministry of Mines and Energy and the Society of Petroleum Engineers (SPE) initiated by National Petroleum Corporation of Namibia.

Furthermore, he is part of Pycon Namibia a non-profit organisation that offers training in data analysis, machine learning and artificial intelligent using phython programming language. He is passionate about science and the use of advanced technological tools to find solutions to challenges facing communities.

Following reverse listing, public can now acquire shareholding in Paratus Namibia


20 February 2020, Windhoek, Namibia: Paratus Namibia Holdings (PNH) was founded as Nimbus Infrastructure Limited (“Nimbus”), Namibia’s first Capital Pool Company listed on the Namibian Stock Exchange (“NSX”).

Although targeting an initial capital raising of N$300 million, Nimbus nonetheless managed to secure funding to the value of N$98 million through its CPC listing. With a mandate to invest in ICT infrastructure in sub-Sahara Africa, it concluded management agreements with financial partner Cirrus and technology partner, Paratus Telecommunications (Pty) Ltd (“Paratus Namibia”).

Its first investment was placed in Paratus Namibia, a fully licensed communications operator in Namibia under regulation of the Communications Regulatory Authority of Namibia (CRAN). Nimbus has since been able to increase its capital asset base to close to N$500 million over the past two years.

In order to streamline further investment and to avoid duplicating potential ICT projects in the market between Nimbus and Paratus Namibia, it was decided to consolidate the operations.

Publishing various circulars to shareholders, Nimbus took up a 100% shareholding stake in Paratus Namibia in 2019 and proceeded to apply to have its name changed to Paratus Namibia Holdings with a consolidated board structure to ensure streamlined operations between the capital holdings and the operational arm of the business.

This transaction was approved by the Competitions Commission as well as CRAN, following all the relevant regulatory approvals as well as the necessary requirements in terms of corporate governance structures.

Paratus Namibia has evolved as a fully comprehensive communications operator in Namibia and operates as the head office of the Paratus Group in Africa. Paratus has established a pan-African footprint with operations in six African countries, being: Angola, Botswana, Mozambique, Namibia, South Africa and Zambia.

The group has achieved many successes over the years of which more recently includes the building of the Trans-Kalahari Fibre (TKF) project, which connects from the West Africa Cable System (WACS) eastward through Namibia to Botswana and onward to Johannesburg. The TKF also extends northward through Zambia to connect to Dar es Salaam in Tanzania, which made Paratus the first operator to connect the west and east coast of Africa under one Autonomous System Number (ASN).

This means that Paratus is now “exporting” internet capacity to landlocked countries such as Zambia, Botswana, the DRC with more countries to be targeted, and through its extensive African network, Paratus is well-positioned to expand the network even further into emerging ICT territories.

PNH as a fully-listed entity on the NSX, is therefore now the 100% shareholder of Paratus Namibia thereby becoming a public company. PNH is ready to invest in the future of the ICT environment in Namibia. The public is therefore invited and welcome to acquire shares in Paratus Namibia Holdings by speaking to a local stockbroker registered with the NSX. The future is bright, and the opportunities are endless.
