The water sector is set to continue to face severe challenges in meeting the financial requirements for maintaining, extending and upgrading new and ageing water systems in the face of growing water scarcity, stricter regulatory requirements and competition for capital. The gap between the required financing and the projected financing is said to be growing but there are no good estimates available. The purpose of this paper is to present a recent analysis of the investment requirements of the water sector in OECD countries, Brazil, Russia, India and China up to 2030, taking into account the likely impact of socio‐economic trends, internal politics, environmental challenges and technological change.

In order to estimate the required financing, present expenditures as a percentage of GDP were analysed. Estimates of projected annual GDP growth coupled with an evaluation of the impact of country specific socio‐economic, political, environmental and technological trends were used to derive projections for future investment needs.

The estimated level of infrastructure investment requirements to 2030 as determined by this study is considerably higher than had been expected and higher than for the energy, telecommunications and transport infrastructure sectors.

The findings have enormous implications in terms of the ability of service providers for their business models and in raising the necessary finances.

This is one of a very few studies to report on the potential scale of the overall future investment requirements of the water sector that has been undertaken. Previous works have focused mainly on sub‐sectoral goals such as meeting the Millennium Development Goals and so have under‐reported the scale of the financing problem.

The purpose of this paper is to present a methodology to evaluate the capital investments in infrastructure projects managed by private operators considering uncertainties in the operation and maintenance of the infrastructure components.

The methodology described in this paper is based on two major sources of information: deterioration curves of the infrastructure systems obtained from Markov chain models and the value of flexibility obtained from a real options analysis.

Using this methodology, it is possible to determine whether there is value if project managers adopt flexible strategies in determining capital investments. These strategies refer to the opportunities of postponing, deferring or canceling capital investments required to maintain the operation of the infrastructure systems.

The model utilizes Monte Carlo simulation and real options analysis to overcome the complexities associated with the solution of the differential equations that represent the variability of the main factors in the project cash flow.

The methodology presented in this paper can be used by public officials, private investors, and asset managers to determine the value of flexibility associated with the strategies required to maintain the operation of infrastructure assets.

Minimal private participation for infrastructure development continues to affect developing economies like South Africa. This study aims to determine the perceived occurrence of challenges delaying the delivery of water infrastructure assets and the role of both public and private financing for infrastructure development.

Quantitative approach was used, and questionnaires were administered to stakeholders that have participated in delivering water infrastructure assets in South Africa. Of the 96 returned questionnaires, 91 were usable, representing 61 per cent response rate. Data from the survey were analysed using descriptive and exploratory factor analyses. The reliability test represented a value of 0.945, indicating internal consistency.

Data analysis revealed that corruption, hostility, weak project structuring, high fiscal deficits by state government, cost recovery constraints, high credit risk for private financing and unreliable planning and procurement processes are major challenges delaying the delivery of water infrastructure assets. More so, municipal government remains the key custodian of water infrastructure delivery with limited support from private capital as a result of political administrative instability, legislation and policy uncertainty and inadequate risk-adjusted returns.

Emphasis should be made on eradicating corruption and non-transparent financial management to improve municipal creditworthiness and amending and implementing much improved legislation and foreign inclusion. Additionally, financial models to complement the existing mechanisms of financing water infrastructure projects should be sought and used. Complete eradication of infrastructure challenges envisages to reduce fiscal deficits, improve service delivery and enhance the competitiveness and productivity of the economy.

The purpose of this paper is to develop an investment valuation model using the mezzanine debt mechanism based on blue bonds that explicitly allude to public–private partnerships (P3s) and project finance (PF). Additionally, this study proposes the financial captured value (FCV) theory for measuring how much financial value lenders may capture by becoming sponsors through financing of sustainable infrastructure systems (SIS).

The investment valuation model was validated through the Aguas Claras wastewater treatment plant as a case study.

The empirical results show that lenders may capture financial value by converting outstanding debt into equity shares throughout the operation and maintenance stage. Furthermore, case study results provide new insights into the implications of the debt–equity conversion ratio on the relationship between the sponsors’ internal rate of return and the FCV.

The most significant limitation is the lack of primary and secondary information on blue bonds. Thus, robust statistical analyses to contrast results were not possible.

Researchers and practising professionals can improve their understanding of how mezzanine debt, P3s and PF into an investment valuation model allows financing SIS using a non-conventional financial mechanism. The recommendations will benefit both the academia as well infrastructure industry in bridging the gap between design theory and practice.

Sustainability components have not been addressed explicitly or combined in the financing’s structuring. Therefore, the investment valuation model could be considered a novel methodology for decision making related to financing and investment of SIS.

Targets set out by state institutions, with respect to supplying water to deprived communities, seem to be idealistic and not realistic. Study envisioned to assess challenges of financing water infrastructure projects, and determines the role of the state towards infrastructure development by holistically planning and engaging with the private sector.

The study adopted a quantitative approach, whereby a questionnaire survey was conducted among different stakeholders involved in water infrastructure projects in South Africa. Data gathered were analysed using percentages, mean item score and standard deviation.

The study revealed that most challenges affecting the success of the financing of water infrastructure projects in South Africa are corruption, hostility towards private participation, cost recovery constraints, high fiscal deficits by state government, unreliable planning and procurement processes, and a rapid increasing number of municipalities that lack technical and administrative capacity to plan implement, operate and maintain water assets.

This research paper investigates projects’ financing challenges with a broad inspection on the role of the public sector. The apparent role of the international structures such as OECD, IMF and World Bank had no influence in the study. From the findings, it is clear that the central government and state institutions lack the necessary resources to accelerate infrastructure development, water infrastructure in particular. The study, thus, recommends a complete expansion and development of state capacity as well as improved collaborations with the private sector to drive the success delivery of services to the public.

Improved and flexible regulations and legislative guidelines are required to ensure that both sectors fulfil their side of the bargain, with an ultimate goal of meeting the predetermined targets of supplying adequate water to the deprived communities.

The purpose of the paper is to examine the impact of infrastructure investment and development on economic growth in Brazil, Russia, India, China and South Africa (BRICS) countries. The effect is examined for each country separately and also collectively by combining each country.

Ordinary least square regression method is applied to examine the effects of infrastructure investment and development on economic growth for each country. Panel data techniques such as panel least square method, panel least square fixed-effect model and panel least square random effect model are used to examine the collective impact by combining all countries in BRICS. The dynamic panel model is also incorporated for analysis in the study.

The results of the study are mixed. The association between infrastructure investment and development and economic growth for countries within BRICS is not robust. There is an insignificant relationship between infrastructure investment and development and economic growth in Brazil and South Africa. Energy and transportation infrastructure investment and development lead to economic growth in Russia. Telecommunication infrastructure investment and development and economic growth have a negative relationship in India, whereas there is a negative association between transport infrastructure investment and development and economic growth in China. Panel data results conclude that energy infrastructure investment and development lead to economic growth, whereas telecommunication infrastructure investment and development are significant and negatively linked with economic growth.

The study is novel as time series analysis and panel data analysis are used, taking the time span for 38 years (1980–2017) to investigate the influence of infrastructure investment and development on economic growth in BRICS Countries. Time-series regression analysis is used to test the impact for individual countries separately, whereas panel data regression analysis is used to examine the impact collectively for all countries in BRICS.

Within the new public management (NPM) context, this paper aims to examine the inclusion of equity issues in pricing policy development and implementation in the water industry in Australia.

A review of literature relevant to the pricing of water shows equity issues have four dimensions which tend to be, at best, only implicitly considered. An empirical illustration employing a transaction cost framework is provided of a case in which change in pricing mechanisms was strongly suggested.

An equity paradox emerges as an explanation of why 63.7 per cent of Queensland urban water entities chose not to adopt the user-pays pricing mechanism for water. This suggests that the balance between “equity” and “efficiency” continues to be required in policy development for water pricing. Equity of access and that of distribution continue to be significant factors. As well, equity of interest and of return must be considered, especially under a user-pays pricing mechanism.

In respect of NPM considerations, it is argued that consideration of the four dimensions of equity in the implementation of a water pricing policy will resolve contradictions with, and paradoxes met in dealing with efficiency.

The argument used in the paper is interdisciplinary. References and terms used include those which are social, economic, and environmental from an accounting and management perspective.

This paper aims to report on the partial findings of a research project on risk allocation in public–private partnership (PPP) water projects. It identifies risk factors encountered in PPP water infrastructure projects, evaluates their associated risk levels and presents an authoritative risk factor list to assist the sector institutions to understand the important risks associated with such projects in Ghana.

A ranking-type Delphi survey was conducted to develop a rank-order list of critical risk factors.

Twenty critical risk factors with high impact on water PPPs were established. The top-five risks relate to foreign exchange rate, corruption, water theft, non-payment of bills and political interference.

Being the pioneering study, it holds implications for practitioners. By prioritising the risks according to their relative impacts on the success of water PPP projects, public and private participants will become more aware of and leverage efforts and scarce resources to address those significant factors with serious consequences on projects objectives. The paper adopts a research approach that can be used by future researchers in similar environments where PPP is novel and experts are hard to find.

This paper focuses on the long-term situation with water resources, and water sector in particular, analyzed through a Foresight study. The authors attribute particular attention to implication for Russia, which is relatively better positioned regarding the availability of water resources. However, the country still faces challenges related to the protection of water resources, drinking water supply, water networks, consumption patterns, water discharge, treatment and re-use. The present study aims at identification and analysis of trends, factors and uncertainties in water supply, demand, use and re-use with a particular focus on sustainability of water systems; water use by households and industry; and new water services and products.

Research methodology in this paper involves a horizon scanning exercise for the identification of the key trends, factors and uncertainties along with the identification of weak signals of future emerging trends and wild cards in the form of future surprises, shocks and other unexpected events that may disrupt the preservation of water resources and the future of the water sector. Trends characterize broad parameters for shifts in attitudes, climate, policies and business focus over periods of several years that usually have global reach. These are usually experienced by everyone and often in similar contexts. Trends may represent threats, opportunities or a mixture of them, identified through underlying processes, possible events and other future developments.

A key systemic restriction of water use for the next decades both globally and in Russia relates to competition between agriculture, energy, manufacturing and household water use. Given that the amount of renewable water resources is almost fixed and even decreases because of pollution, circular economy solutions for water use will be required. Implications of the global trends identified in the study for Russia are dependent on the overall situation with water resources in the country. Russia has sufficient water supply: the overall intake of water for drinking and economic purposes in Russia amounts to 3 per cent of the total water resources, two-thirds of which are discarded back to water bodies. At the same time, there are substantial problems associated with the extremely uneven distribution of water resources across the country, as well as high “water intensity” of the Russian GDP. The Russian water sector is currently not very attractive for investors. Moreover, it has significantly less lobbying opportunities than other infrastructure sectors, and this complicates its institutional and financial positions. Meanwhile, there have been some positive changes with regard to activities with a short pay-off period.

The paper offers one of the first studies on the future of Russian water resources with a focus on the water supply and sanitation sector. A comprehensive approach to trends identification (not found in other studies on Russian water resources) allowed authors to identify social, technological, environmental, economic, policy and value-related global trends and uncertainties. Moreover, implications of these trends and uncertainties, as well as Russia-specific trends, were outlined.

This paper aims to identify and evaluate the most significant risk factors that strongly affect the implementation of public–private partnership (PPP) water supply projects. PPP for water supply infrastructure services has seen continued growth over the past two decades, following public sector’s budgetary constraints and inability to provide infrastructure-based water services efficiently and cost effectively. However, these projects are often subjected to major risks leading to failures.

Following extensive literature review and case study analyses, an international questionnaire survey was conducted with practicing and experienced PPP experts to establish the significant risks in PPP water projects. Both the probability of occurrence and severity of 40 risks were evaluated by the expert panel to determine their significance and impact on water projects procured under the PPP arrangement.

The paper presents a derived risk factor list, ranks the factors and describes the “top-ranked” risk factors as: poor contract design, water pricing and tariff review uncertainty, political interference, public resistance to PPP, construction time and cost overrun, non-payment of bills, lack of PPP experience, financing risk, faulty demand forecasting, high operational costs and conflict between partners.

This factor list broadens PPP stakeholders’ view of important project risks, rather than relying on culture-dependent studies – an area that has received less attention in PPP risk management research. The identified risk factors would provide governments and investors a useful tool in implementing constructive water PPPs by facilitating the development of risk mitigation strategies, particularly for developing countries with poor risk management practices.
