Islamic University of Lebanon support water conservation off campus through on rain water in the main form as an alternative to the water received from the Ministry of Energy at a rate of 80% of use. Noting that the water of wells is not used except in days of scarcity, allowing the rest of the surrounding areas to benefit from the surplus water available.
The university secures from its sources water for the agricultural areas surrounding the campus, (See figure 1) in agreement and coordination with the municipality and the owners of neighboring properties.
The university for its construction project incorporated architectural elements on the campus in which all the requirements related to the surrounding environment were developed and studied, including the lack of a source for use and drinking water, and the absence of an infrastructure that would cover the needs of the buildings included in the project. Consequently, the university infrastructure was equipped with the development of four networks to prevent contaminated water from entering the water system, as follows:
Rain water from the roads
The project is equipped with seven ground tanks with capacity of 1400 m3 with a water collection system from the roads. The collected water is used in the irrigation system of the agricultural lands surrounding the project.
Rainwater from the roofs and balconies
Ground tanks (from R1 to R4 .in blue color) with total capacity of approximately 2900m3 were built distributed over the entire project. Ceilings were designed diagonally to collect water and deliver it to the tanks separately, see next figure, the consumption rate of each student:
