In-Depth Information
The proposed technologies for concept scenarios 1 and 2 have a strong
focus on the reuse and recycling of water, nutrients and energy. Table 5
shows examples for technologies that allow a recovery of nutrients, energy
and reuse of water.
TABLE 4:
Key objectives and characteristics of the three concept scenarios.
Scenario
Key objectives
Characteristics of technologies under
this scenario
1. Local
identity
The goal of this scenario is the
conservation of local identity
which is related to the cultivation
of chinampas and the prevention of
external influences.
In this concept scenario individual
technical solution are preferred over
centralized ones to become more
independent from Mexico City.
2. Economic
development
The goal of this scenario is economic
development with a strong focus on
agriculture. In the mountainous areas
where no agriculture is practiced,
there is a focus on community
development.
In this scenario there is a strong
emphasis on sanitation systems that
allow the reuse of nutrients and the
water in the chinampas or in some
other areas to improve the agricultural
production. In the hilly area, community
technologies are the main feature of this
scenario.
3. Centraliza-
tion
The main goal is a strong
connection to the development of
Mexico City and integration into the
planned urbanization.
All infrastructure services are
centralized as much as possible.
