Factors Associated

This study aims to analyze the factors associated with willingness to pay for improved water supply system in rural Tanahu, Nepal. For this purpose, one hundred and twenty seven households were proportionately distributed among wards 5, 6, 7 & 8 and selected for data collection. Structured questionnaire was used to collect the data. Chi-square test was used to find the factors associated with willingness to pay for improved water supply system. This study shows that there is no any significant association between willingness to pay for improved water supply system and social, demographic and economic variables. However, water source, dental pain, water quantity, want for change are water fetching time have significant association with willingness to pay for improved water supply system. Cases of Jaundice is significantly associated with willingness to pay for improved water supply system However, there is no significant association between willingness to pay and satisfaction from WUC activities, water purification, diarrhea, dysentery, seasonal flu, and suffering from worm. So, it can be concluded that type of water source, quantity, fetching time, will for change, and prevalence of some disease (Jaundice, Dental Pain) are the major factors influencing willingness to pay for improved water supply system in the study area.apriya Journal of Interdisciplinary Studies, Vol. 5 (December 2016), Page: 1-13

Abstract Discontentment with a piped supply system of drinking water has become a significant concern in Bangladesh's urban areas in recent years, necessitating the improvement of different aspects of the system in question. Therefore, by conducting a discrete choice experiment on 115 households out of a systematically selected 161 households, this study aims to estimate the willingness to pay (WTP) for an improved safe drinking water supply by considering the trade-offs made by urban dwellers for the proposed improvements to an existing water supply system in the Khulna City Corporation (KCC) area of Bangladesh. The primary results show that the total WTP of households is estimated at BDT 243.6 (≈US$ 2.87) per month, implying that respondents are ready to pay for improvements to the water supply attributes of water quality, regularity of supply, water pressure in taps, and filtering. A revenue stream for an improved water supply system is also being developed, suggesting that investment in improving the system would be a ‘no-regret’ decision and economically sustainable.

In The Beginning

<p>Investigations of tap water and its source groundwater reflect combined features of regional hydrological processes and human activities including the changes in water supply system (WSS). In this context, multi-parameter characterization can present a reliable tool to propagate the geochemical “fingerprints” of water source from natural or artificial mixing. If the geochemical composition of different water source end members is significantly different, we can estimate the proportions of source water and their changes from particular source to tap.</p><p>To test this hypothesis, we performed a 24 hours sampling experiment of tap water in April 2019 at selected location in Ljubljana (i.e. at Jožef Stefan Institute), where groundwater from two different water fields and aquifers (i.e. from Kleče at Ljubljansko polje and Brest from Ljubljansko barje) is mixed. In-situ measurements of temperature, electrical conductivity and pH were performed and 25 water samples were collected hourly for determination of isotopic composition of oxygen (<em>δ</em><sup>18</sup>O), hydrogen (<em>δ</em><sup>2</sup>H) and dissolved inorganic carbon (<em>δ</em><sup>13</sup>C<sub>DIC</sub>), <sup>87</sup>Sr/<sup>86</sup>Sr isotope ratio and major (Ca, K, Mg and Na) and trace elements (Ag, Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, Tl, U, V and Zn).</p><p>The diurnal variations of parameters are not very large; however, temporal differences of some parameters (e.g. Ba, Mg) indicate that proportion of groundwater from Kleče and Brest water fields changed during the experiment. Based on observed temporal differences during the 24 hours experiment we could identify three different patterns: a.) higher values in the beginning and at the end and lower in between (i.e. <em>δ</em><sup>18</sup>O, <em>δ</em><sup>13</sup>C<sub>DIC</sub>, Ca, Na, B, Ba, Cr, Li, Sr); b.) lower values in the beginning and at the end and higher in between (i.e. K, Mg, As, Mn, V) and c.) higher values at the beginning of experiment (i.e. Cd, Co, Cu, Fe, Mo, Ni, Pb, Sb, Zn). The first and the second pattern (a and b) indicate the mixing of different groundwater from different water fields with different geochemical characteristics. The third pattern (c) however indicates the influence of release of elements due to corrosion of water supply system. Based on results of 24 hours experiment and additional information on functioning of water supply system changes in proportion of water from Kleče and Brest water fields will be estimated.</p>

PurposeThe purpose of this paper is to support the development of effective strategies that enhance community water supply systems. The study examined service constraints and willingness to pay for better services in community-managed water supply services using empirical evidence from beneficiaries of a small-town water supply system in Ghana.Design/methodology/approachA survey design of both descriptive and exploratory research is adopted, the descriptive survey handles the quantitative aspect, while the exploratory survey handles the qualitative aspect. The authors collected data using a structured survey questionnaire from 387 beneficiaries who were public standpipe and domestic users. Descriptive statistics, Kendall's coefficient of concordance and Cragg's two-step model were the methods of analysis employed.FindingsThe respondents ranked lack of capacity (managerial) as the topmost constraint of the community-managed water system. The findings indicate that 57% of the beneficiaries were not willing to pay, whiles 43% were willing to pay. Also, results from Cragg's two-step regression model indicate that different sets of factors affect willingness-to-pay and amount-to-pay decisions. The study revealed that while a willingness-to-pay decision is influenced by income, education, marital status and customer service, the estimated-amount-to-pay decision is more influenced by income and education.Originality/valueBuilding on the empirical evidence, the findings indicated that the water and sanitation management team can increase the current fee of GH¢ 5.00/1 m3 (≈US$ 0.87) by increasing beneficiaries charge for a bucket of water from GH¢ 0.10p (≈US$ 0.017) to GH¢ 0.21p (≈US$ 0.036) for better services within the community. Importantly, the additional charge should take into consideration income and education which were noted to significantly influence the beneficiary's amount-to-pay decision for better services in the community-managed water supply system.

Special Focus

The aim of that research is to analyse the evolution of human activities close to Lake Bolonha, one of the main surface water sources for the Water Supply System in downtown Belém and Ananindeua, is investigated. Research consists of three stages. Stage 1 characterizes the environs and evaluates the importance of Lake Bolonha within the urban context. Stage 2 identifies human activities in the last ten years in the environs of the water source. Stage 3 analyzes impacts and environmental degradation risks, with special focus on vegetation around the lake. Results show that urban expansion reduced riparian vegetation and triggered sewerage flow into the lake, compromising self-cleaning capacity in the medium and long term, with an increase of pollution/contamination. The administration should develop and intensify activities to avoid irregular land occupation, establish a sewerage system and restitute the riparian vegetation lost. Lake Bolonha is highly relevant for the water supply system of approximate one million people of Belém and Ananindeua within the metropolitan region of Belém, Brazil.

Abstract The paper presents the main types of surface water incidental contaminations and the security method against incidental contamination in water sources. Analysis and assessment the collective water supply system (CWSS) protection against incidental contamination was conducted. Failure Mode and Effects Analysis (FMEA) was used. The FMEA method allow to use the product or process analysis, identification of weak points, and implementation the corrections and new solutions for eliminating the source of undesirable events. The developed methodology was shown in application case. It was found that the risk of water contamination in water-pipe network of the analyzed CWSS caused by water source incidental contamination is at controlled level.
