Developing countries, normally accompanied with water-constrained
conditions, tries to adapt gradually the World Health
Organization (WHO) guidelines for more flexible approaches as targets

Furthermore, the playing ground in the water supply sector is
more open to private companies [000] and they act as a monopoly of
governmental organizations in most of the countries, but in case of
Turkey, key actors of the total water management is still the local
governmental water authorities. There is a huge tendency of socializing
the water supply industry to share the financial burden of the Governments
[00] private sectors could participate in the process by delivering
professional service packages as in Public–Private Partnerships
(PPPs) models [000]. Water management authorities and companies
should not only consider the benefits of market value but also environmental
benefits or the increase in the availability of a scarce resource.
