The Cost

Water is increasingly becoming a scarcer commodity, particularly in large cities of developing countries. Drinking water is an important use of water which has been catered for by most of the local governments. However, it is provided with a varying degree of reliability and the cost of this is not known. Consumers would like to pay for a reliable water supply besides what they pay for the normal water supply (both quantity and quality of water supplied). This paper presents an application of the contingent valuation method (CVM) for estimating the value of reliable water supply in National Capital Territory (NCT) – Delhi. The study implications and the lessons accruing from it are also summarized.

Water scarcity is an alarming issue in the developing world. Due to population explosion, the supply of water to households is becoming difficult. And as the quality of water supply infrastructure is deteriorating, clean water is getting mixed with sewage and becoming a cause of waterborne diseases. This study was carried out in the city of Lahore, Pakistan, to find out the willingness to pay (WTP) for improved water supply by using Contingent Valuation Method (CVM). This study explores the relationship of WTP with socio-economic factors, i.e. income, accommodation and employment. Moreover, questionnaires were administered to randomly selected 200 respondents. For statistical analysis stepwise linear regression, Pearson correlation and chi square were employed to find out the variables that determine WTP for improved water supply quality. Results showed that income was the variable that most significantly impacted the WTP for improved water supply. The WTP amount was found to be 0.70 USD. People were not generally satisfied with the water supply quality. Unavailability of water for 1–2[Formula: see text]h per day was commonly reported by the respondents. However, more studies should be conducted with a larger sample size to enhance our knowledge about water supply situation in Lahore.

Nowadays，our country has a relative density of population, so once a fire occurs  in  the  building, personnel  evacuation  is more difficult. Since fire and water have no mercy and the fire spreads quickly, it will endanger people’s life and property safety if unable to fully guarantee the quality of water supply and drainage for fire control. Scientific and rational water supply and drainage  system  for  fire control  can  effectively increase the efficiency and speed of fire rescue, reduce people’s property loss and improve  the  residential safety index of the building itself. In view of this, this paper mainly analyzes the characteristics and design key points of water supply and drainage engineering for fire  control  in  high-rise buildings.

The purpose of this study is to estimate and analyze the willingness to pay  and fax tor the factors that affect the willingness to pay at High School in the of Semarang. The method used is Contingent Valuation Method (CVM) and multiple linear regression analysis. The number of samples in this study were 238 respondents, the sampling technique was done by snowball sampling. The results of this study indicate that the average willingness to pay (WTP) of households in High Schools in Semarang is Rp.559.034,00. Factors that have a significant influence on WTP values are income variables, number of household dependents, age and length of access. Whereas the factors that have no effect on willingness to pay (WTP) are parents' education variables. Based on the results of the study, the suggestions that can be put forward are the management or the government to improve the quality of the Vocational School as well as the development of a transparency policy on the collection and allocation of user fees and other resources.

As an important construction link in the construction project, the quality of the water supply and drainage directly affects the overall quality of the construction project. Because of the strong function of the water supply and drainage project, the construction quality is easily affected by the construction method. For this reason, construction enterprises should attach importance to the mastery of water supply and drainage construction methods. And further understand the relevant precautions of construction water supply and drainage construction, in order to achieve the purpose of improving the quality of water supply and drainage construction.

Water Supply Services

The assessment of existing water supply services was carried out through selected performance indicators with the aim of using that data in future for strategic planning of urban Mardan. The key performance indictors studied were selected to assess both the quantity and quality of water. The quality of water was assessed by turbidity, pH, and E-coli tests for samples collected at the start, middle, and tail end of the distribution system. The quantity of water supplied was measured by calculating discharges from water tapes at the three selected locations in the distribution system. A total of thirty samples were collected from ten union councils out of fourteen covering urban Mardan. A number of issues are highlighted in the overall water supply infrastructure and short, mid, and long term remedial measures are recommended. The results are presented in the form of an interactive map using Google Earth and VBA based dynamic database. It was found that the overall quality of water is generally acceptable for drinking. However, the presence of bacteria is an issue in many cases which needs to be resolved. A significant decrease in discharge is observed in the distribution systems away from the source due to leakages and illegal connections. A comprehensive overhaul of both management and infrastructure is required for sustainable and satisfactory level of services.

This document proposes a methodology for assessing the quality of water distribution service in the context of intermittent supply, based on a comparison of joint results from literature reviews and feedback from drinking water operators who had managed these networks, with standards for defining the quality of drinking water service. The paper begins by reviewing and proposing an analysis of the definition and characterization of intermittent water supply (IWS), highlighting some important findings. The diversity of approaches used to address the issue and the difficulty of defining a precise and detailed history of water supply in the affected systems broadens the spectrum of intermittency characterization and the problems it raises. The underlined results are then used to structure an evaluation framework for the water service and to develop improvement paths defined in the intermittent networks. The resulting framework highlights the means available to water stakeholders to assess their operational and management performance in achieving the improvement objectives defined by the environmental and socio-economic contexts in which the network operates. Practical examples of intermittent system management are collected from water system operators and presented for illustration purposes (Jeddah, Algiers, Port-au-Prince, Amman, Cartagena, Barranquilla, Mexico, Cancun, Saltillo, Mumbai, Delhi, Coimbatore …).
