Water  & Wastewater

Water

South Africa is a semi-arid, water-stressed country. It is estimated that, based on current usage trends, water demand will exceed availability by 2025 (current estimates show that this has already been reached). The continuing trend in industrialisation and urbanisation of the population is expected to place further pressure on the country’s sources of water supply unless appropriate corrective action is taken.

There are six major water use sectors, namely, irrigation, urban use, rural use, mining and bulk industrial, power generation and forestation. The combined total water requirement for all user sectors for the year 2000 was 13 280 million m3/a.

Wastewater

South Africa has 986 wastewater treatment plants most of which are relatively small systems (half treat less than 0.5 Ml/day).

Although these are based on an ageing infrastructure, an in-depth survey showed that the need for additional or upgraded plant infrastructure or the need for additional funding is not the root cause of the poor performance at the majority of surveyed plants

The most pressing need is the critical shortage of trained, skilled and experienced process controllers and mechanical / electrical maintenance staff and the information necessary to guide optimised operations.

Challenges facing the Water and Wastewater industry

Water Industry

Balancing supply and demand by minimising waste

Instant municipal leak detection and what to do about it can be made automatically available to qualified personnel with any mobile device, for example. Automatic, remote monitoring and logging of meters saves a great deal of human resources and cost and also facilitates billing.

Water quality and availability

Monitoring water quality from source to destination through remote but collated measurements using today’s wireless SCADA and IIoT technologies can help with the early detection of anomalies.

Optimised use of effluent

Due to water scarcity all pollutants and effluent streams will increasingly need to be treated to ever higher standards before being discharged.

Lack of necessary skills

Many geographically-distributed companies are concentrating their knowledge base and information resources in a central location in order to maximise their efficacy.

Wastewater Industry

Establishing new skills and competencies

This is especially relevant in poorer communities. The lack of trained personnel is the single biggest challenge facing the wastewater industry in South Africa. This is an area where industrial automation and industrial IT technology can drastically turn things around in the short term and provide the breathing room required for long-term solutions.

Infrastructural, mechanical and electrical maintenance

this depends on personnel who, even if they don’t have the necessary training, can be guided remotely on proper maintenance procedures through mobile devices.

Network and infrastructure information

Geographically-distributed systems benefit from centralised SCADA and information systems backed by a central pool of expertise for event resolution and guidance.

Residue and sludge management / disinfection

Inadequate disposal and use of sludge were recorded at 81% of the plants while none of the plants included in the survey would comply with the new SA Sludge Guidelines. While training will help, measurement leads to quantifying performance against regulations.

Environmental impacts and regulatory compliance

30 % of plants require immediate intervention to avoid crisis situations such as an outbreak of waterborne diseases. In the short to medium term intervention would be required at more than 66 % of the plants. The Department of Water Affairs and Forestry requires a 95 percentile compliance to the conditions stipulated in the authorisation but if these performance criteria were strictly enforced, only 4 % of the surveyed plants are adequately operated and maintained.
