“…Alternatives to intermittent supply regimes exist as well, such as investing in water desalination capacity or raising prices for the limited supply available [135]. Studies have shown that users are willing to pay for improved domestic supply reliability [85,98,117,122,136,137].…”

Communities in many parts of the world, especially in developing countries, face obstacles in supplying continuous water to household consumers. Authorities often cite water scarcity as the cause, but we demonstrate that environmental constraints constitute only one aspect of a multi-dimensional problem. By asking what causes intermittent domestic water supply, this literature review (129 articles) identifies 47 conditions of intermittent systems and the causal-consequential pathways between them that can reinforce intermittency. These pathways span several disciplines including engineering, government administration and anthropology, and when viewed together they (1) emphasize the human drivers of intermittency; (2) suggest generalized interventions; and (3) reveal a gap in the literature in terms of meaningful categorizations of the reliability of intermittent supplies. Based on the reliability of consumers' water access, we propose three categories of intermittency-predictable, irregular, and unreliable-to facilitate comparisons between case studies and transfers of solutions.

“…Instead, people choose alternative means to obtain water of the desired quality like boiling, chlorination or filtering tap water, purchasing bottled water or a combination of these methods. In developing countries, such alternative measures can be less accessible and more expensive (Whittington et al 1991). For instance, Ferrier (2001) estimates that the average price of bottled water worldwide is 500 to 1000 times more expensive than tap water.…”

Household’s Perception of Water Quality and Willingness to Pay for Clean Water in Mexico City

Abstract:A 2011 survey of Mexico City's households revealed that families prefer alternative sources of drinking water instead of relying in the city's quality supply services. These include the purchase of bottled water, installation of filtration devices, and other means of water purification. The demand for better water quality was tested by estimating the household's willingness to pay (WTP), using a contingency valuation (CV) experiment through an open-format questionnaire and by estimating a censored econometric (Tobit) model. The econometric study revealed that the WTP for better water quality is influenced by variables related with distrust of the water quality provided by the City and the organoleptic characteristics of the water supply, as well as spending on bottled water or water purification technologies. The average WTP surcharge for better potable water quality is US$3.1 or 4.7% of the bimonthly water bill, which is about 0.22% of the average family income in Mexico City. The percentage of WTP to income is bigger in poor families. This suggests that improving water quality is of greater importance for lower income families. Findings are consistent with previous studies that estimated the WTP for improvements in the services that supply water to households in the city. These include reduction of inefficiency and intermittency of the supply along with water quality, improve measuring water meters, reducing the obsolescence of the infrastructure and increasing adequate maintenance. Our research is the first to estimate the WTP for better water quality in Mexico City and constitutes a reference point for those that address the problem of water quality and its impact on the welfare and income of families.

“…This implies that the overdependence on water tankers is both unjustifiable and unsustainable. Whittington, Lauria and Mu (1991) observed that, on annual basis, households in Onitsha, Nigeria pay water vendors over twice the amount required to operate and maintain a piped distribution system. In some cases, the source of water supplied by tankers cannot be guaranteed especially during periods of peak demand or scarcity.…”

Two multi-criteria decision analysis methods were employed to evaluate six water sources. The analytical hierarchical process (AHP) ranked borehole highest with a rank of 0.321 followed by water board with a rank of 0.284. The other sources ranked far below these two as follows: water tanker (0.139), rainwater harvesting (0.117), shallow well (0.114) and stream (0.130). The Technique for Order Performance by Similarity to the Ideal Solution (TOPSIS) ranked water board highest with a rank of 0.865, followed by borehole with a value of 0.778. Quality and risk of contamination were found to be the most influential criteria while seasonality was the least.
