In Lebanon there are four types of natural water that is not drinkable:
1. heavy water (dissolved calcium and magnesium) in the hills above the coast
2. salt water on the coast
3. fertilized water (high dissolved nitrate) in the interior of Lebanon and Bekaa,
4. spring water (low in minerals) mainly in the mountains.
For each type of water a customized filtration system is needed in order to make it drinkable. Currently, water in public facilities is not suitable for human consumption, as these institutions do not have enough funds from the government to improve the quality of their services and infrastructure.
Especially, public schools are facing a number of illnesses and a decline in school results due to absenteeism and poor student concentration as children become sick in class. An urgent need for the installation of water filtration systems was discovered.
Composition of water purification system
- Carbon filter
- Sediment filter (50 or 30 microns)
- Filter and Sediment (5 or 1 micron)
The carbon filter treats the water color and taste. Through the other filters small deposits are removed from the water. These filters are connected to a closed water tank, which is directly connected to the water network of the Water Authority. In order to kill all bacteria in the water, ultraviolet light is used.
The water filtration system must be at least changed every four months.
The ultraviolet lamp weakens its function after 85,000 hours. It should be changed annually or if it is disrupted. This device works on electricity and is connected to an electric valve, so that if the power is cut off, water can still be filtered.
Teachers and parents of the schools have been taught on how to exchange the filter.
The following process is undertaken for each potential school in order to identify the suitable filtration system:
1. Water analysis (3 weeks)
2. Filter specifications (1 week)
3. Purchase of equipment and installation (16 weeks)
4. Water analysis after installation (4 weeks)
5. Oversee continuation of the project after funded by the parents' committee, the school administration and the municipality of each zone.
The Rotary Clubs in Lebanon will be responsible to partner with local companies to install customized water filtration systems at each of the schools. The parents' committee, the school administration and the municipality are all responsible for the continuity of the project. Agreements have been signed with the latter to take care of the change of filters in schools in order to make the project sustainable.
