3.Project Description

3.1Project Components

The Project is divided into two main components:


  1. The Awali-Beirut Water Conveyor

  2. Improvement and rehabilitation of the water distribution network in Beirut and its suburbs

The first component includes conveying of water from Joun to Khalde via an underground tunnel where it would be then piped through conventional means (piping through road service corridors) to two storage reservoirs in Hadath and then to a third reservoir in Hazmieh. The Awali-Beirut Water Conveyor sub-components are summarized in Table 3 -21 and their geographical locations are illustrated in Figure 3 -2.

Figure 3 2 Geographic location of project components



Component 2 will comprise the following:

  • The construction of 16 reservoirs (between 500 m3 and 1000 m3 storage capacity each) and associated pumping stations distributed across the various distribution zones in the project area;

  • The replacement and/or installation of approximately 187 km of distribution network across the project area in Ein El Delbi, Southern Beirut and parts of the Metn area;

  • Installation of 200,000 household meters in portions of the project area to be selected by the GBMLWWE and to operate on a volumetric tariff basis;

  • Installation of bulk meters at the reservoirs and distribution chambers;
  • Table 3 -22 and Table 3 -23 show characteristics of the above mentioned reservoirs and pumping stations along with areas they serve. This information is to be confirmed in final stages of the design of the second component.
