2 IMESA I MQS enables asset-intensive organisations to leverage ongoing information communications technology (ICT) innovation, coupled with expert advisory and support services, to deliver tangible performance improvements," explains Knight. “The backbone of our offering is our proprietary GIS-centric software, which is 100% developed by IMQS; is benchmarked against the best available globally; and forms a vital part of the AM toolbox,” Knight continues. “For each client, we first design the data model so it delivers the information required to reliably monitor the nature, extent, and status of the portfolio, and at an appropriate level of detail. Then – once we’ve mapped out every asset – its precise location, health and performance is recorded at a frequency appropriate to its use via IMQS’s intuitive GIS Web-interface, which is automatically integrated with IMQS’s digital asset register.” Within the NEXTEC Group, IMQS forms part of the Infrastructure Consulting Division, which includes GLS Consulting (GLS) and JOAT. GLS is an expert in the analysis, planning and management of water distribution, sewer, and electricity reticulation systems, while JOAT is a leading specialist in water systems’ optimisation. “The founders of GLS started IMQS as a digital front-end to their engineering businesses. This was the foundation for the continued evolution of the current IMQS AM business model, moving from desktop software to the web and now the cloud,” Knight explains. Today, IMQS employs some 100 specialist personnel, interacting with around 70 AM clients, the bulk of which are municipalities. IMQS works across all infrastructure asset classes – like water, wastewater, roads, electricity, and buildings – to provide an integrated and holistic AM model. “Over the past 15 years, we’ve worked directly with more than 120 municipalities. We’ve also started to engage more at a provincial level. A current example is the Western Cape Department of Transport and Public Works, where our scope includes schools, hospitals, and provincial buildings,” says Knight. AM defined But what is AM? Essentially, it is about using a systematic methodology to optimise the value of assets to achieve the best and most cost-effective result over their life cycle, which in the case of public infrastructure is service delivery. Based on global experience, key aspects of management practice that are required are reflected in SANS 55001: 2014, though the way these are applied need a keen appreciation of the objectives and the operational context. Staying current with the latest AM trends, Childs is a World Partners in Asset Management (WPiAM) board member, as well as a council member of the Southern African Asset Management Association (SAAMA). One of the key developments is the South African Qualifications Authority’s (SAQA’s) recognition of the AM Global Certification Scheme (GCS) recently launched by SAAMA in partnership with WPiAM. There are three designations, namely Certified Senior Principal in AM (CSAM™), Certified Practitioner in AM (CPAM™), and Certified Technical Specialist in AM (CTAM™). “This is a major step forward as it recognises AM as a profession that makes a key contribution worldwide in getting the COVER STORY INFRASTRUCTURE ASSET MANAGEMENT SOLUTIONS MADE IN SA Forming part of the NEXTEC Group of Companies, IMQS is a specialist software and engineering services provider with a solid track record for implementing intelligent infrastructure asset management (AM) programmes within municipalities. IMIESA speaks to IMQS’s Rob Knight, CEO, and Rob Childs, Executive: Professional Advisory & Support Services, about what AM means in practice. WORLD-CLASS

IMESA 3 COVER STORY infrastructure delivered that we need as a society - across a wide range of industries and sectors, public and private,” says Childs. For the bulk of municipalities struggling with ailing infrastructure, Childs says that improving AM practice is the key to restoring balance to the blend of operations, maintenance, upgrades and new works. To function effectively though, AM programme implementation requires an in-depth education process at all levels within organisations and the infrastructure processes must integrate effectively with enterprise resource planning systems, especially in terms of financial accounting and management. “One of the greatest threats to effective AM is poor procurement practice. This is especially the case where municipalities pursue maintenance initiatives without effective planning and prioritisation. Expenditure can then occur in a fragmented/siloed way with the risk of major cost overrun and wastage implications. Procurement managers must keep life-cycle cost optimisation top of mind,” stresses Childs. Plan, Build, Operate and Assess IMQS’s AM methodology is systematic, virtual, and structured on a Plan, Build, Operate and Assess approach, supported by the applicable software module(s). At the heart of the IMQS platform is the IMQS Project Control System (PCS), which enables users to centralise all project-related data on one easy-to-use and spatially enabled platform for all applicable asset classes. PCS’s two core benefits are: • dynamic tracking and management of capital and operational projects in line with life-cycle asset management criteria • effective oversight, with a clear audit trail. An example of how this works in practice is the City of Tshwane, which has hundreds of projects ongoing, worth billions of rand. “Attached to each of those projects we have recorded completion certificates, invoices, etc., so it’s a transparent system that greatly minimises the risk of irregular expenditure,” Knight explains. It all starts with a plan Planning is not a once-off event, but an ongoing process of understanding and influencing demand, designing for a future state while, in parallel, assessing the current network’s condition and need to upgrade or renew assets. IMQS provides specialist advisory services on strategic and tactical decision support tools and solutions for the design, modelling, and prioritisation of activities. All municipalities are required to draw up and implement Integrated Development Plans, informed by future spatial development frameworks and plans for ongoing maintenance – the upgrading and expansion of infrastructure forming the backbone. An example would be plans to respond to forecasted water and wastewater treatment demand over a 5-, 10- and 15-year horizon. IMQS’s mandate is often to provide a roadmap for the improvement of management practice relating to an organisation’s AM, which starts with an ‘as is’ assessment of management practice. It’s a test at any point in time about the skills and capability of a client to manage their assets. “Based on that, we provide a plan to improve those capabilities over time,” says Knight. Pursuit of the roadmap inter alia enables the efficient application and management of capital for existing and new infrastructure works. And indeed, visible competency and corporate commitment in this area, in itself, can elevate the ability to access capital funding. Maintenance Management For repairs, IMQS’s geospatial, mSCOA compliant Maintenance Management software package, which links directly to the municipality’s AM register, proves invaluable. The programme integrates, automates, and unifies all maintenance-related data sources, processes, and reporting. It also makes municipal engineering tasks easier in terms of key aspects like incident logging and scheduling. An example is the issuing of a works order for an intervention like a burst pipe or pothole repair. Maintenance Management ensures that the correct tools, trained technical personnel, repair instructions, infrastructure locations, and materials are assigned the first time, significantly reducing cost overruns, like overtime, as well as rework. The same cost-saving principle applies to planned future work. More niched software tools include IMQS's Road Infrastructure Management System and its subset, the Pavement Management Module (PMS). They provide a clearly defined set of procedures for collecting and analysing relevant data so that maintenance and management needs for entire road networks can be identified, alternative treatments assessed, prioritised, and budgeted for. Another allied product is IMQS’s Wayleave software, which enables effective planning where multiple works are planned for the same section, e.g. a new pipeline, fibre optic cabling and a road reseal. The first prize would be to complete all three jobs at the same time. Rustenburg From a case study perspective, Rustenburg Local Municipality is an example of an AM success story. IMQS started to roll out its programme with the municipality some three years ago. “We started from scratch, focusing initially on water and sanitation infrastructure in partnership with GLS to establish a digital representation of their networks. Today, they are one of the biggest users of our Maintenance Management system, which has been integrated into their call centre,” Childs explains, adding that Rustenburg is now also a DBSA pilot study in terms of the latter’s asset care programme, and part of a potential national initiative. “The final piece of the AM puzzle is the ongoing assessment of data quality. That enables decisions on where improved or enhanced data acquisition opportunities can add value, as well as influencing the selection of new technologies to further enhance life-cycle cost optimisation,” adds Knight. South Africa shows the way Within the AM world, South Africa is recognised as a trailblazer, with leaders like IMQS continuing to refine its techniques as new Internet of Things tools become available. “South Africa faces major infrastructure challenges and opportunities and, in this respect, effective AM certainly serves as a positive catalyst for socio-economic growth,” Knight concludes. www.nextec.co.za • Organisational Asset Management Framework and Competency Development Roadmaps • Asset Management Objectives, Performance, Risk and Financial Management Strategies • Prioritisation and Budgeting • Integrated Strategic and Sector Asset Management Plans • Strategic optimisation of maintenance management • Financial Asset Management and Accounting IMQS ASSET MANAGEMENT ADVISORY AND SUPPORT SERVICES

4 IMESA IMESA MISSION STATEMENT To promote excellence in the engineering profession for the benefit of municipalities and their communities.

IMESA 9 WELCOME President’s Welcome Message Our last in-person conference was in 2019 before the beginning of Covid-19 restrictions. It is sobering to reflect on the impact that the pandemic has had since then on every aspect of our individual lives, our communities, our country and globally. Thankfully, we can now put that behind us and once again host a physical event where public and private stakeholders can map a way forward. It is a pleasure to be able to welcome you to our 85th IMESA Conference hosted by our Northern Provinces Branch. This year’s theme, which is ‘Adapting to our changing world’, has never been more relevant as we engineer our way through the very real fallout from climate change, as well as global conflicts, to hopefully build a better future. Our thanks go to the sponsors and exhibitors who contribute so much to our conferences. Thanks also go to the Local Organising Committee (LOC) and Head Office staff for all the hard work that goes into organising and coordinating a successful and interactive conference. IMESA is hosting the second 2022 board meeting for the International Federation of Municipal Engineering (IFME) and, this time, we have the privilege of an address by their President, Sanne Hieltjes, as well as invaluable international input on the topic of ‘Climate Change, Technology and Stewardship – adapting infrastructure assets for a changing world’ by the conference’s keynote speaker, David Jenkins from the Institute of Public Works Engineering Australasia. The conference papers this year cover crucial topics like solving flooding problems using sustainable urban design systems (SUDS), as well as the opportunities for independent water production in South Africa. In addition, we will be hearing from representatives of National Treasury and other government authorities on our discussion panel. There will be Q&A sessions throughout and ample opportunities to network with speakers and representatives in the Exhibitors’ Hall. I invite you all to take full advantage of the wealth of experience and information offered over the three days and to participate in all the activities on offer. Bhavna Soni President, IMESA

10 IMESA The Small Coastal Storm Water Outlets guidelines can be downloaded from the knowledge base library on the IMESA website under Stormwater. Guidance for local authorities regarding reclamation and reuse of water was identified as a priority in 2019 and IMESA was called on to support the development of guidelines in a project sponsored equally by the Water Research Council (WRC) and IMESA. We are proud to announce that the Water Reclamation and Reuse Guide for South African Municipal Engineers was completed this year, and the final document was launched by the WRC on 1 September 2022. The guideline can be downloaded under Water in our knowledge base library. IMESA will present training workshops based on these guidelines, starting with a pre-conference workshop in Johannesburg on 1 November 2022 and then rolling out to Cape Town, Durban, Gqeberha and George in 2023. The development of a best practice guideline for Design Flood Estimation in Municipal Areas in South Africa was also identified as a critical aspect for municipalities. This was initiated as a project by IMESA and co-funded by the WRC. The project has made good progress, and the guideline will be showcased at the Knowledge Bar at the 2022 IMESA Conference. Strategic Liaisons Engagements with external bodies were limited last year but IMESA has had valuable interactions with National Treasury, ECSA, SALGA, CESA, SAICE, the WRC and others this year. Civil Engineers South Africa (CESA) – The Excellence Awards presented jointly by CESA and IMESA every second year could not be held in 2020 but submissions were called for and evaluated in 2021, with the winners being announced and presented at a special awards ceremony held in Cape Town in November 2021. A Memorandum of Understanding between IMESA and CESA was signed this year and we look forward to more interaction that benefits all our members. Engineering Council of South Africa (ECSA) – A full audit by ECSA of IMESA as a CPD-licensed body took place in July 2022. IMESA was commended for following the required protocols for the verification of CPD service providers and the accreditation of CPD activities. Further interaction will take place to ensure that IMESA keeps up to date on all relevant legislation and requirements. At a meeting held in January 2022 with Mr Cox Mokgoro, acting CEO of ECSA, I explained my vision of ethics being made a compulsory component of CPD for engineers as an extension of the ECSA Code of Conduct. South African Forum for Engineering (SAFE) – Several meetings have been held this year. The forum will continue as intended in its original MoU, as it is proving to be a valuable opportunity for professional bodies As my term as IMESA President rapidly comes to an end, I am reminded that one of my key mandates was to motivate for ethics to be made a compulsory part of the CPD cycle for registration with the Engineering Council of South Africa (ECSA), by requiring registered practitioners to attend an ethics presentation annually during their five-year registration cycle. I have presented the concept to ECSA and will continue to work for this as I firmly believe that engineers’ adherence to ethics is crucial to move forward with any success, especially in our municipal environment. Both civil and municipal engineers must stand together in ensuring that we live up to the Code of Conduct for Registered Persons in terms of the Engineering Professions Act (Act No. 46 of 2000). From IMESA’s perspective, our role is to assist and empower our members and to work within the three spheres of government to make municipal engineering processes and projects more efficient and effective. This is crucial for the successful implementation of South Africa’s economic reconstruction and recovery plan, and the revitalisation of our construction industry. The disastrous floods earlier this year in KwaZulu-Natal highlighted this priority. In terms of current and future spatial planning, we need more advanced research on extreme weather predictions along the lines of those countries that need to design and build for potential seismic activity in earthquake zones. Not easy, of course, given the extensive unpredictability of climate change impacts. But with the information we do have available, we can certainly construct far more robust structures. As municipal engineers, we also need to urgently address the pressing issue of informal settlements within our towns and cities. These settlements occur wherever open land is available, irrespective of whether its above or below a known floodplain. It’s a potential disaster waiting to happen and can and should be prevented. Of equal importance is the regular updating of municipal asset management registers, with examples including transportation infrastructure and water/ sanitation networks. Preventative and predictive maintenance is a key factor in ensuring the current and future sustainability of the municipal landscape. IMESA Projects With Covid-19 restrictions now repealed completely, we can restart our training programme. IMESA technical courses are being planned for 2023 and the details will be shared with members as soon as the schedule is confirmed. 2022 President’s Address PRESIDENTIAL ADDRESS 2022 President’s Address

IMESA 11 PRESIDENTIAL ADDRESS representing a wider range of engineering disciplines to discuss issues legislation and regulations. South African Local Government Association (SALGA) – Although there have been fewer opportunities for interaction this year, IMESA has maintained contact with SALGA at a national level for support on communication with municipalities. Water Research Commission (WRC) – IMESA has sponsored two projects in joint ventures with the Water Research Commission as described above. Work on both projects will be completed this year and will address critical issues in municipal engineering. National Treasury – The efforts for professional bodies and other stakeholders to consolidate and prioritise their issues for National Treasury have achieved some positive outcomes but there are several supply chain management and interpretation of policy issues that have not been addressed yet or have been referred back to the municipalities. It might be more effective for IMESA to approach the representatives of National Treasury, CoGTA, CIDB, SALGA, MISA and SAICE that they have held meetings with previously. International Federation of Municipal Engineers (IFME) Between 22 and 24 June 2022, associations from around the world gathered in Rome for the International Federation of Municipal Engineering’s Annual Convention. This included IFME’s first of two board meetings for the year. As the President of IMESA, I had the honour of representing South Africa at this convention, sharing key infrastructure challenges with municipal engineering counterparts from Asia, Europe, North America and the Middle East. Presentations focused on ways to achieve a sustainable green transition within the urban context. Key topics included the reimagining of sustainable urban spaces, smart mobility and asset management. The latter topic is especially important in managing and progressively upgrading ageing infrastructure, particularly water and sewer pipelines. Stemming non-revenue water losses remains a global concern, both from an environmental and financial perspective, so this is an aspect where a great deal of IFME knowledge sharing takes place. The second IFME board meeting, being hosted by IMESA, coincides with IMESA’s 85th Annual Conference in November 2022. Exco and Council This year sees the election of a new IMESA President as well as the Executive Committee and Council for the 2022-2024 period and I will be handing over as IMESA President to the capable hands of Mr Sibusiso Mjwara at the 2022 IMESA Conference opening function. I wish him well with taking IMESA forward and will be happy to support him during his tenure. The new Exco and Council members will no doubt also play their part in taking IMESA forward in our fast-changing world. Membership and Branches The last year has been difficult to navigate with Covid-19 again impacting on our annual conference, which had to be held online in 2021, and preventing many of our branches from holding their usual activities. Our Exco and head office staff have worked hard to keep IMESA’s finances in good order. There was a drop-off in membership, sadly indicating the tough times faced by many members, but it is encouraging to see many returning and new members rebuilding with IMESA this year. At our Strategic Planning Meeting in March 2022, several priorities were identified regarding branches. The Free State/Northern Cape branch is to be re-established after the retirement/relocation of branch committee members. Branches are to be set up in neighbouring countries for IMESA to support their local municipalities and to bring in more members from the Southern African region. A Branch Chair Forum has been formed to discuss local issues, share lessons learnt and refer matters to Council. We encourage members to get involved at the branches and to let us know how we can provide more technical development opportunities and assist members to conquer common engineering challenges. IMESA has branches covering the following regions: • Northern Provinces (Gauteng) • Free State/Northern Cape (Bloemfontein/Kimberley) • KwaZulu-Natal (Durban) • Border (East London) • Eastern Cape (Port Elizabeth) • Southern Cape/Karoo (George/Mossel Bay) • Western Cape (Cape Town) • SADC countries.

12 IMESA Finances and Investments The loss of income from not being able to hold the 2020 IMESA Conference and holding an online event for the 2021 IMESA Conference has required careful management. Thanks to the efforts of our Operations Director: Finance, with the support of Exco/Council and head office, the Institute continues to operate and maintain a secure financial position. Alternative income sources are being considered for future security when membership contributions and conference activities might not be sufficient. Obituary Sadly, we have noted the passing of several members: Barend Deminey, Corné Du Toit, Mansoer Mallick, Johan Abram Landman, Andries Lötz, and Giulio Gerald Govoni. These members will all be remembered for their individual contributions to IMESA and will be commemorated at our AGM on Wednesday, 2 November 2022. In Summary This Conference is just one of the ways IMESA uses to promote excellence in engineering, not only through innovation and technology but also by supporting ethics and professionalism. To the optimist, the glass is half full. To the pessimist, the glass is half empty. To the engineer, the glass is twice as big as it needs to be.” We all know that South Africa has many challenges such as scarce water resources, high water loss, aged infrastructure, climate change and limited finances, to name a few. IMESA would like to create platforms that will assist the municipalities to resolve these challenges in the most efficient and cost-effective ways. To do that, we need the support of the various municipalities, their municipal managers and their respective mayors to meet with IMESA on the different platforms and to work together to resolve South African challenges. Another IMESA priority is to support young engineers by providing training, workshops and mentoring, as well as encouraging them to uphold all professional engineering principles. They are our future engineers to support the municipalities and provide service delivery to South African citizens. To end on a lighter note, I leave you with this quotation: “To the optimist, the glass is half full. To the pessimist, the glass is half empty. To the engineer, the glass is twice as big as it needs to be.” PRESIDENTIAL ADDRESS Between 22 and 24 June 2022, associations from around the world gathered in Rome for the International Federation of Municipal Engineering’s Annual Convention. This included IFME’s first of two board meetings for the year

LOC WELCOME WELCOME LOC Chair Address I t is with immense pleasure that, as LOC Chair, I welcome you to the 85th IMESA Conference, hosted by the Northern Provinces Branch. We are honoured and privileged to have delegates from all over South Africa attending, including our exhibitors and sponsors, and all our IMESA members who make up a large contingency of those attending. This year highlights the attendance of IFME (International Federation of Municipal Engineering) from various parts of the world, including Australasia and Europe – we look forward to hearing from them. As a collective entity, it is our responsibility to work towards solutions that not only institute measures that drive sustainability, but also provide education to all those attending. Our theme this year – ‘Adapting to our Changing World’ – is particularly relatable, as each one of us can clearly see how our world has already changed and is changing. We are pleased that our papers represent all disciplines in the industry, and we thank our speakers for the many hours spent on their presentations. I am confident that the content to be delivered by our peer-reviewed speakers will stimulate relevant dialogue pertaining to this thoughtprovoking theme. Events to look forward to include our opening function and the inauguration of the new IMESA President, a golf day at the well-known Benoni Country club, our ever-popular technical tours, and our very popular social evening, which is not to be missed. For our delegates who bring their companions, we have a very exciting companions programme over a three-day period. This takes place away from the conference but will ensure that the companions have a lot of fun while enjoying some of what Gauteng has to offer – a mere tip of the iceberg. This year’s panel discussion on Wednesday afternoon is bound to conjure up some very well debated points, which may be discussed further over the remaining days. It is sure not to disappoint. I must highlight the fact that our Conference wouldn’t be a success today without our exhibitors and sponsors with whom we have forged relationships over the years, and we thank them for their continued support. Our Local Organising Committee has done a great job in terms of assisting Head Office’s Conference Department with this year’s Conference. We know that the success is attributed to hard work and I thank all those who are involved and the time they have offered up. IMESA 13 Gavin Clunnie LOC Chair, IMESA Many thanks to the Team that contributed to the overall success of the Conference.

24 IMESA SPONSORS HERRENKNECHT AG Mechanized tunnelling for South Africa´s water and sewage projects Herrenknecht looks back on 45 years of experience in mechanized tunnelling. As the world´s leading manufacturer of tunnelling equipment, Herrenknecht maintains a close partnership with its customers, who have successfully completed countless tunnelling projects worldwide. Based on an international service network and reliable technology not only for tunnelling, but also for pipeline installations and shaft sinking, Herrenknecht provides mechanized solutions for ambitious upcoming projects and their successful completion. Tunnels for sustainable underground infrastructure Population growth goes hand in hand with the need for today's cities to develop sustainable infrastructures for traffic, supply and disposal networks. As space is restricted on the surface, more and more utilities like power cables are moved underground. Existing sewage networks have to be expanded, new large-capacity schemes have to be built to meet future requirements in volume or growing challenges in flood protection. Water transfer and supply tunnels and the implementation of seawater desalination plants require long tunnels, on- and offshore. In all kinds of ground conditions In mechanized tunnelling three different shield have been established on countless pipe jacking and segment lining projects worldwide: Slurry Shields (AVN/AVND/Mixshields), Earth Pressure Balance (EPB) Shields with screw conveyor and Open Shields with conveyor belt behind the cutting wheel (Single/Double Shield, Gripper). Each of these proven methods has advantages in its special application range. In changing ground conditions along the alignment, combined solutions can be considered. Lining methods for small-diameter tunnels For South Africa´s upcoming water and sewage projects, the mentioned machine portfolio will be needed to cover the range of prevailing ground conditions. In the small diameter range of tunnel ID of up to 4 meters, pipe jacking and segment lining can be considered. Pipe Jacking has a long tradition in the trenchless construction of sewer networks or link sewers. On an international scale, technological advance and valuable experience gained by the contractors have pushed the boundaries in pipe jacking in terms of achievable drive length and tunnel diameter. At the same time, small-diameter segment lining is considered for 3-meter inner diameters and larger, as was the case for the main collectors on Doha´s IDRIS project and Singapore´s deep tunnel sewerage system. Basis of project success in tunnelling The decision to plan and execute a small-diameter tunnelling project whether with pipe jacking or segment lining is mainly driven by the specific project requirements such as length, diameter or depth of the tunnel. Clients and planners need a broad knowledge about the available technological alternatives to go for the best-suited method. Subsequently, the close cooperation of technology supplier and contractor to design the tunnelling equipment will ensure a safe and reliable project execution. herrenknecht.com/en Herrenknecht AVN 1000 lowered into launch shaft on Cape Flats - Khayelitsha Main Water Supply Pipeline Project - 2021

As a growthoriented individual, he has committed to developing both his technical and management abilities, holding postgraduate degrees in transportation engineering and business management. His contributions and mindset in the workplace have made him one of the young provincial directors at Siyazi Group of Companies. PAPER 6 ESAIAS OOSTHUIZEN Siyazi Group Esaias Oosthuizen is a public transport specialist with an MEng (Transportation) and is especially well known for his success in the development of liaison structures between the authorities and the taxi and bus industries. He has an effective way of working with the industry at all levels, particularly at grassroots level. It is acknowledged that he understands the taxi operations better than most planners. He is uniquely equipped to interpret the real operations and shortcomings of the public road transport system owing to his involvement in the planning of infrastructure and also the many surveys he conducted in different parts of South Africa over more than 30 years, coupled with his close relationship with members of the taxi industry. He could help to improve the accuracy of taxi-related modelling, for example in conjunction with specialised computer packages used for modelling purposes. The results and applications of the ITP process could be of great value and would probably outperform any other similar combination. SPEAKERS

48 IMESA PAPER 1 Rajiv Paladh & Jay Bhagwan THE OPPORTUNITY FOR INDEPENDENT WATER PRODUCERS IN SOUTH AFRICA President Ramaphosa highlighted the need for Independent Water Producers to contribute towards South Africa's water security future during the 2020 budget speech. The Water Research Commission initiated a study that explored this opportunity within the South African water legislative and institutional framework. This paper thus presents the findings from the study, and details future steps that need to be completed to establish Independent Water Production in South Africa. An Independent Water Producer (IWP) is an entity, which is not a publicly owned utility, but which owns and operates facilities to produce water for sale to customers. Customers can include utilities, central government, municipalities and end users (industry or farmers). There are two broad pathways for the introduction of IWP in South Africa. This is either the introduction of IWP within the existing legislative and institutional framework or amending the current framework to allow for the introduction of IWP within the existing water value chain. Including IWP within the existing legislative framework may require the introduction of additional regulations to prevent unintended consequences. The opportunity for IWP in South Africa exists around desalination, wastewater reuse and small scale production for industry. IWP could therefore be implemented by focussing on Water Boards and Water Services Authorities (WSA) that: • Are developing programmes around desalination and wastewater reuse; • Have strong credit ratings; and • Would benefit from streamlined processes for procuring these projects. An alternative approach would be to develop a single off-taker with sovereign guarantees to procure water from IWP on behalf of Water Boards and WSAs. Industry will develop its own water supply to ensure security of supply in the appropriate conditions. This additional supply and possible redundancy is useful for building resilience in the broader water sector and the national economy. However, it does pose threats to municipal revenue. Restrictions and uncertainties created in the regulations around water sector intermediaries are the biggest barrier to industry doing this and should be improved. However, these activities should not be subsidised through public funds. The study raises several key questions and positions on the role and inclusion of IWPs in the water sector. A key question is around the issue of what independence actually means in the South African landscape. Any issues of licensing and allocation of water resources raise the conflict of independence. Key Presentation Impact Points: 1. What is Independent Water Production? 2. How could IWP be implemented in South Africa? 3. Key steps towards the introduction of IWP in South Africa. PAPER 2 Tjeerd Driessen QUANTITATIVE FLOOD RISK ASSESSMENTS FOR THREE TOWNSHIPS IN JOHANNESBURG USING HIGHRESOLUTION MODELLING This project focused on the widespread illegal dumping in river floodplains which predominantly comprises of building rubble and fill material for creation of platforms and development of shacks. The proliferation of these informal developments is no longer sustainable as it is already resulting to encroachment of the floodplains, unsafe living conditions, damage to existing infrastructure and possible increase in flood risk due to changes in the river hydrology. These impacts are expected to worsen if no interventions are taken. The objective of this study was to assess the flood risk increase due to illegal dumping along the water courses in Alexandra, Kaalfontein and Diepsloot. This project was commissioned by City of Johannesburg and implemented by Johannesburg Road Agency. Six state-of-the-art, cloud-based, two-dimensional flood models were developed using Digital Terrain Models with 1m horizontal resolution. For each area, two flood models were generated; one representing the 2012 (pre-dumping) situation and one representing the 2019 (post-dumping) situation. An extreme value analysis of the rainfall events of the three areas was done to determine the normative rainfall durations and depths which were required to force the hydraulic models. A total of 28 modelling scenarios were simulated using combinations of different time horizons (2012 and 2019), different areas and different return periods (ranging from 5 to 100 years). Not only were the flood lines derived for each scenario, but also water depth maps, water level difference maps and flood hazard rating maps were generated. This gave a good first insight how the response of the river system changed as a result of the illegal dumping of building material in the floodplains. A quantitative flood risk assessment was performed to gain a deeper understanding of the economic impact of floods and how the flood risk changed between 2012 and 2019. This assessment was performed using a Global Flood Risk Tool which is a cloud-based platform that quickly and accurately calculates flood damages and flood risk as a product of the modelled flood hazard maps, land use maps and vulnerability functions of the exposed assets. The study found among others that during a 100-year return period event water level increases of up to 1.8m could occur as a result of the illegal dumping. Also, the economic flood risk (i.e., expected annual direct flood damage) increased by 12-15% for Kaalfontein, 33-34% for Diepsloot and 8-10% for Alexandra between 2012 and 2019. Key Presentation Impact Points: 1. Townships are often located in flood-prone areas and face increasing risks to flooding. 2. A deep understanding of the flood risks of urban rivers is required. 3. Quantitative flood risk assessments can assist with prioritising interventions, support urban planning, assist disaster risk management, create awareness among communities and is a stepping stone towards social resilience.
