The research addresses the problem of drinking water
that exists in Iztapalapa from Mexico City. Iztapalapa
delegation is the most populous and the one presenting most
drinking water problems in Mexico City. The problems
affect the entire delegation, especially highly marginalized
areas such as those found in the foothills of the Sierra de
Santa Catarina, San Juan and San Lorenzo Tezonco. The
main problems are quality and scarcity. The contingent
valuation method was used to estimate the willingness
to pay (DAP) of residents by improving water quality.
A survey was applied to 95 users. 42% of respondents
had the perception that water pollution is high, 38% of
pollution is regular and 12% said that water pollution is
very high. Regarding water scarcity, 39% said that this is
high, 42% that is regular and 12% which is very high. The
estimated average of willingness to pay was $ 5.00 dolars
per bimester, obtianing an approximate economic value of
$ 13.25 million dollars per year for the payment of water.
The variables that best explained the model were price,
age, education and gender. Variables like marital status,
family size, income, perceived water quality and water
scarcity perceived were excluded as these did not have an
explanation from the model for 95% of reliability.
