Privatization is a complex issue in many developing countries; therefore, it is vital to examine the obstacles that prevent its proper implementation. The goal of this study is to identify and analyze the barriers to private sector investment in the Water and Sewage Industry (WSI) and to suggest effective ways to attract the private investors to this sector.

The obstacles to private sector investment in the WSI were identified by conducting a desktop literature review and interviewing an expert panel, using the fuzzy Delphi technique. The most important barriers were identified and categorized. A structured survey was then developed and distributed to private sector investment experts. The Fuzzy Analytic Hierarchy Process (FAHP) was applied to further examine the responses and to rank the identified barriers.

The results showed that the greatest barrier to privatization is the weakness of insurance companies in controlling investment risks, and the second greatest barrier is the weakness of the country's capitalist culture. A review of recent success stories revealed that these barriers can be overcome with transparent price policies and increased interaction between the public and private sectors, which motivate private investors to invest in the WSI.

The elicitation of this study can be useful to both private and public sectors for the development of infrastructure projects, particularly for the WSI.

Quantifiable data produced in a national report by the Environment Agency of England and Wales entitled Water Pollution Incidents in England and Wales 1997 and published by the Stationery Office in 1998, identifies over 3,723 substantiated pollution incidents across England and Wales in 1997. Within the generic sector classed as “Industry” the construction industry was the most frequent polluter responsible for 22 percent of all substantiated water‐related pollution incidents in that sector. The report also identified that a significant number (28 percent) of all substantiated pollution incidents across England and Wales are directly attributable to mineral‐based fuels and oils, many of which are used extensively within the construction industry. This paper seeks to locate the possible causes and effects for some of that oil‐based pollution, discusses the issues and identifies a unique and radical client‐motivated solution within the UK to reduce and mitigate the undesirable impacts upon the environment. Evidence produced by the oil industry shows the enormous amount of one particularly aggressive pollutant – hydraulic oil – which remains annually, unaccounted for. Hydraulic oil is used in most tracked earthmoving machinery; the sort of machinery most closely associated with construction work carried out near to watercourses. Biodegradable hydraulic oil is much more considerate to the environment, but is more expensive and not usually installed in new plant and machinery. The paper argues that on a life cycle basis the use of biodegradable oil is viable and feasible and that there are many external factors that make its usage desirable.

To compare the profitability and technical efficiency of firms in a monopoly industry, airports, operating with different degrees of market power and under differing regulatory regimes, minimalist in New Zealand and interventionist in Australia.

Unlike previous privatisation studies, this study measures efficiency and profitability separately. Using data envelopment analysis (DEA), the technical efficiency of privatised airports is assessed, and this independent measure is used in regression analyses to determine whether efficiency, regulation or privatisation is related to airport profitability.

For firms with monopolistic characteristics operating under minimalist regulation, profitability is related to market power, not efficiency improvements. For firms operating in a regulated environment, profitability is related to regulation, which constrains market power but does not impede efficiency.

This study is limited by its small sample size and its generalisability due to its single industry and regional focus. However, the findings support assertions that the impact of privatisation cannot be assessed independently of industry structure and regulation.

Policy makers considering SOE privatisation in non‐competitive markets should introduce either competition or regulation if firm efficiency is a desired outcome.

Academics and policy makers should be aware that privatisation and competition are not only complementary, as per the extant literature, but they are essential bedfellows. In the absence of competition, regulation is required to control for market power.

State-owned enterprises (SOEs) are essential tools to further policy objectives across the world. However, in the past few decades, heated debates on the performance of SOEs vis-à-vis private sector enterprises have surfaced. In India, SOEs have long played an important role in the economy and only recently have undergone the trend of privatization. The purpose of this paper is to analyze existing research and to conclude whether private enterprises perform better than SOEs.

A review of available literature on performance comparisons of public and private sector enterprises is carried out, and differences between public and private enterprises are studied. Finally, theoretical propositions on the differences in objectives of public and private enterprises in the Indian context are enumerated. Three propositions are tested using data on Indian SOEs available in the public domain.

Performance comparisons of public and private enterprises have focused merely on technical productivity or financial aspects and have thus left out the wide scope of social, economic and political objectives of SOEs. Literature on the nature of SOEs indicates that there are certain fundamental differences in the objectives of public and private sector enterprises. Further, the basic theoretical assumptions tested have been found to be, prima facie, valid in the Indian context. The paper thus establishes a case for further research to develop a comprehensive technique for the comparison of public and private sector enterprises in the Indian context.

Extant research on the subject of comparing public and private entries has limited itself to technoeconomic considerations and has not taken into account the different objectives/nature of these enterprises. The study established a case for diverging from the present discourse privatization and private sector supremacy. The same could have far-reaching consequences for policymakers, especially in developing countries.

The bulk batch fabrication process of thick film technology has been utilised in the design and production of miniature amperometric dissolved oxygen sensors based on potentiostatic and voltammetric operation. Three different polymers have been investigated as membrane materials – cellulose acetate, PTFE and PVC. PTFE has been deposited on the devices by aerosol spray and PVC and cellulose acetate by screen‐printing. These methods have been shown to be effective membrane fabrication techniques, and have significant implications in the field of chemical sensors as a whole. All the membrane covered devices investigated were found to exhibit sensitive and linear responses to dissolved oxygen. The effects of temperature and flow rate on sensor response have been investigated and the use of PVC and PTFE in place of cellulose acetate have been shown to reduce both effects. These membranes have also been shown to reduce the detrimental effects of fouling observed on the surfaces of cellulose acetate covered devices as they are powered in tap water.

Investigates the green cost attributable to water consumption in the hotel industry and accommodation operations in Hong Kong. An abatement cost approach plus a prorated model were used in the green costing. The study surveyed 20 hotels on the energy consumption in 1994‐1996 and performed green costing on the major water uses in hotels. Results indicate that green costs per room, attributable to water consumption in hotels range from HK$3.657 to HK$7.641. Implications for green reporting at property level and industry level are discussed, and recommendations are made for future research.

Pakistan is an agricultural country having the world's largest canal irrigation system. Indus basin that covers 70 percent of irrigated area for crop production is the major source of water in the country. Owing to rapid increase in population and uncertain environmental conditions, this water is not adequate to cope with the crop water requirement and needs additional means to provide extra water for agricultural purposes. The main source of irrigation is canal and ground water but the quality of ground water is so poor for the sustainability of agriculture system. To cope with the present demand, use of municipal sewage water that consists of domestic liquid waste, as well as industrial effluents, is becoming a common practice. The present study aims to reflect the hazardous effects of sewage water on the environment, with the main focus on heavy metals and chemical composition of soil and vegetables.

Industrial effluent was collected from one ghee mill, one flour mill, three textile industries and three hosieries located in Faisalabad, an industrial city of Pakistan highly affected with water pollution. All water samples were analyzed for pH, EC, SAR and RSC. Water analysis was also carried out for various nutrients and heavy metals (K⁺¹, P²⁺, Fe²⁺, Cu²⁺, Zn²⁺, Mn²⁺, Ni²⁺ and Pb²⁺). Soil samples from various depths (0‐15, 15‐30, 30‐60, 60‐90 and 90‐120 cm) were taken to analyze for EC, pH, SAR, Na⁺¹, SO₄, K⁺¹, P²⁺, Fe²⁺, Cu²⁺, Zn²⁺, Mn²⁺, Ni²⁺ and Pb²⁺ after irrigation with canal water and sewage water. Cadmium, lead and copper concentration was determined in various vegetables grown in areas irrigated with canal water and industrial effluents to determine their final concentration in the final product ultimately affecting the human health.

Although the sewage water is a source of many nutrients, it also includes a significant amount of heavy metals like Fe²⁺, Cu²⁺, Zn²⁺, Mn²⁺, Ni²⁺, Pb²⁺ and pathogens. Extensive use of this effluent for irrigation purpose has resulted in an upsurge of such metals in soils and various crops, which ultimately resulted in clinical problems in human beings.

The present study reflects the composition of sewage water and heavy metal accumulation in soil, as well as crops. It further highlights the different potential hazards to humans due to these contaminants.

Sewage, particularly the domestic variety, is the major polluter of the aquatic ecosystem in developing Asian countries. Besides eutrophication, it causes a number of waterborne diseases. The growing urbanization in relation to deteriorating water quality; existing practices of sewage management through treatment; reuse and recycling; as well as the legal support to curb pollution are discussed in regard to China, India, Korean Republic and Jordan. Some meaningful suggestions are made for improved sewage management and pollution control.
