2. Main idea
Implementation
of dry latrines to provide the
surrounding communities of lake Atitlán - in the
developing process - of decent and efficient
services that also contribute to clean the
villages and natural wealth.
The eco latrine model doesn’t use water and
substitutes the cesspool (highly polluted) with
containers that decompose the solid excretes
making them less contaminant or, in the best of
cases, takes advantage and uses them as a
fertilizer.

3. Objectives
Avoid
contamination of the phreatic
cloak in lake Atitláns basin.
Improve the life conditions of rural
inhabitants.
Create a volunteer program to install
and control the sanitary units.

4. Goal
Develop
the Project in 3 phases:
◦ Phase 1: installation + training.
◦ Phase 2: change of deposit + use control.
◦ Phase 3: use control + residue stock.
Install
an average of 100 units’ semi
annually.
Favor a population of 1200 people
annually.
