34 CHAPTER 5 WILLINGNESS TO PAY
The highest willingness to pay is to avoid a smell of chlorine in the cold water; the consumers are
willing to pay 64% more to avoid the chlorine smell. The willingness to pay to have water with no
smell at all is insignificant but positive. This indicates that the consumers find that the smell of the
water is very good at present, cf. Figure 5.14.

Avoid the cold water smells of chlorine even after boiling
The cold water has no smell at all
Note: The data is weighted by the age and gender distribution of the Poznan urban region, census 1996.
The water is chlorinated at present. The result here indicates that the consumers are not heavily
dissatisfied with the present smell of the water, but that consumers would be willing to pay higher
tariffs to avoid even more chlorine in the cold water.
If an investment in water services makes it possible to avoid using more chlorine consumers are willing
to accept higher tariffs.
The consumers are willing to pay both to avoid the water getting slightly coloured (with traces of rust)
and to have the water completely clear. This indicates that the water is not perceived completely clear
at present and that the water is not slightly coloured. The consumers are on average willing to pay
41% more on the monthly bill to avoid that the water gets slightly coloured, and they are willing to
pay 24% more to have completely clear cold water.
