The Impact

We examine the impact of poor water quality on avoidance behavior by estimating the change in bottled water purchases in response to drinking water violations. Using data from a national grocery chain matched with water quality violations, we find an increase in bottled water sales of 22 percent from violations due to microorganisms and 17 percent from violations due to elements and chemicals. Back-of-the envelope calculations yield costs of avoidance behavior at roughly $60 million for all nationwide violations in 2005, which likely reflects a significant understatement of the total willingness to pay to eliminate violations.

Water Charges

Governments in developing countries face financial constraints to ensure supply of clean drinking water. They may benefit from increasing water charges for those who are be willing to pay little extra in lieu of their demand for improvement in water quality and service. To check the plausibility of this proposal, we investigated drinking water supply and quality, and welloff consumers demand for improved service delivery in Shah-Rukun-e-alam and Mumtazabad towns in Multan city of Pakistan. Qualitative data obtained through a questionnaire survey was analyzed using descriptive and regression techniques. Qualitative information obtained through semi structured interviews was helpful in designing survey questionnaire and to elaborate quantitative results. Results reveal that the respondents accord high importance to the provision of safe drinking water than to other daily household needs. The demand for improvement in water supply parameters exceeds the demand for improvements in water quality parameters, with the reliable supply being the most demanded improvement. Majority realize the government’s budget constraints in improving service delivery. Most respondents would pay PKR 100 in addition to what they are paying now. Their willingness to pay (WTP) this amount correlates with their awareness on water and health nexus, and depends household income, number of children under 14 years age and awareness of actual water quality tested through laboratory. Besides recommending raise of water charges by PKR 100 per month per household in both towns, the service quality improvement may consider interventions such as mobile water testing laboratory and awareness campaigns motivate citizens to pay for safe drinking water.

If consumers detect an off-flavor in their drinking water, they are likely to believe that it probably is not safe. Water utilities will be defeating their best efforts to provide safe drinking water if they only meet health-related regulations and do not provide water that is free of off-flavor problems. The purpose of this paper is to explore the current U.S. regulatory environment and discuss how these regulations can adversely impact the control of off-flavors in drinking water. Utilities should adopt a water quality goal that allows them to not only meet the minimums of the regulations, but also meet the customer's highest standards - water that is free of off-flavors.

This study characterizes the decrease of the hydraulic conductivity (permeability loss) of a metallic iron-based household water filter (Fe0 filter) for a duration of 12 months. A commercial steel wool (SW) is used as Fe0 source. The Fe0 unit containing 300 g of SW was sandwiched between two conventional biological sand filters (BSFs). The working solution was slightly turbid natural well water polluted with pathogens (total coliform = 1950 UFC mL−1) and contaminated with nitrate ([NO3−] = 24.0 mg L−1). The system was monitored twice per month for pH value, removal of nitrate, coliforms, and turbidity, the iron concentration, as well as the permeability loss. Results revealed a quantitative removal of coliform (>99%), nitrate (>99%) and turbidity (>96%). The whole column effluent depicted drinking water quality. The permeability loss after one year of operation was about 40%, and the filter was still producing 200 L of drinking water per day at a flow velocity of 12.5 L h−1. A progressive increase of the effluent pH value was also recorded from about 5.0 (influent) to 8.4 at the end of the experiment. The effluent iron concentration was constantly lower than 0.2 mg L−1, which is within the drinking-water quality standards. This study presents an affordable design that can be one-to-one translated into the real world to accelerate the achievement of the UN Sustainable Development Goals for safe drinking water.

Access to safe drinking water and potential water degradation have played a role in many water-related investment arbitrations. This paper looks at two different types of investment cases that have emerged with an impact on water: First, it analyses cases that have arisen from privatizations in the water sector. They mainly concern problems connected with physical access to water and affordability. Second, it discusses cases concerning investments in other industries that have the potential to degrade water quality or to have a negative impact on the maritime environment. Using these typical constellations it focuses on the methodology tribunals adopt to deal with potential tensions between the right to water and investor rights.

Abstract Nonfunctionality of engineered water sources after two catastrophic cyclones—Sidr in November 2007 and Aila in May 2009—created acute scarcity of safe drinking water in coastal Bangladesh. The objective of this study was to estimate households’ willingness to pay (WTP) for disaster resilient water sources in Dacope upazila of Khulna District in southwestern coastal Bangladesh. By applying the double bounded dichotomous contingent valuation method to a dataset of 250 randomly selected households, we found that the mean WTP is BDT 263 and that inaccessibility to functional safe drinking water sources is the most significant determining factor of households’ WTP. Projecting mean WTP for a disaster resilient water source project in the study area, we measured a present value of aggregate WTP over project’s life span worth about BDT 624 (USD 7.37) million, which is about 14.30 times the present value of project’s aggregate establishment and maintenance cost. However, charging the local inhabitants a water tariff at mean WTP would lead to the exclusion of around 50% of the people from getting access to the improved water services or create a free riding problem. Through simulation exercises this study determined that the socially optimal water tariff is BDT 50 per month. This tariff would not only generate revenue of more than five times the project cost but would also create access to disaster resilient improved drinking water sources for almost 99% of the people.

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.

Although the United States Safe Drinking Water Act (SDWA) theoretically ensures drinking water quality, recent studies have questioned the reliability and equity associated with community water system (CWS) service. This study aimed to identify SDWA violation differences (i.e., monitoring and reporting (MR) and health-based (HB)) between Virginia CWSs given associated service demographics, rurality, and system characteristics. A novel geospatial methodology delineated CWS service areas at the zip code scale to connect 2000 US Census demographics with 2006–2016 SDWA violations, with significant associations determined via negative binomial regression. The proportion of Black Americans within a service area was positively associated with the likelihood of HB violations. This effort supports the need for further investigation of racial and socioeconomic disparities in access to safe drinking water within the United States in particular and offers a geospatial strategy to explore demographics in other settings where data on infrastructure extents are limited. Further interdisciplinary efforts at multiple scales are necessary to identify the entwined causes for differential risks in adverse drinking water quality exposures and would be substantially strengthened by the mapping of official CWS service boundaries.
