November 29, 2021, South Lebanon - In the midst of the fuel and electricity crises that are affecting the water supply in Lebanon, the South Lebanon Water Establishment, in partnership with UNICEF and Sabil Consortium through funding from the European Union (EU), announced the inauguration of its Maaroub water system consisting of regional reservoirs, upgrading of the Yanouh Pumping station, installation of the main pumping line from Yanouh water station and the gravity lines to connect three villages. The project has been developed to ensure the sustainability of water provision to more than 135,000 people through a system relying on gravity pumping and solar energy.

This new sustainable scheme includes two reservoirs with a total storage capacity of 5,000 cubic metres (2,500 cubic metres per reservoir) and is powered by a sustainable energy source based on a solar-powered system. This will contribute to reducing reliance on the public electricity grid and backup diesel generators, thereby ensuring sustainable and environmentally friendly working and operating mechanisms while maintaining sustainable operation for the infrastructure. The reservoirs’ elevated location allows water distribution by gravity to villages that will benefit from the system, reducing operational energy costs.

Dr. Wassim Daher, Director-General of the South Lebanon Water Establishment, stressed the importance of the partnership with UNICEF, Sabil Consortium, and the EU, which has resulted in a series of key projects vital for the development of the infrastructure of the establishment’s facilities and all levels of production, distribution, and maintenance.

Dr. Daher highlighted the critical support provided by the EU through UNICEF and other partners, especially regarding the construction of 13 reservoirs distributed throughout the various villages and districts of South Lebanon last year, as well as projects to connect water stations and reservoirs and the provision of control, operation, and energy systems.

The South Lebanon Water Establishment Director-General said: "I am confident of the establishment’s capacity to meet current and future demands on water in the project's area. Also, I would like to invite the resident population to join us as new subscribers, and I emphasize the importance of current subscribers to maintain their goodwill and commitment to paying their water bills".

“I would like to extend my thanks to Maaroub municipality for their permanent cooperation and for granting the establishment the Maaroub regional reservoirs location," he concluded.

“The Maaroub project, implemented by UNICEF and the Sabil Consortium, is a successful example of the strong partnership that the EU Delegation has built with the South Lebanon Water Establishment,” said EU Deputy Head of Cooperation, Alessia Squarcella. “Yet, the municipalities of Toura, Jennata, Deir Qanoon Al Nahr, Bedias, Burj Rahhal, and Abbaseyeh should be connected, and we are working to ensure this in the near future.”

“While the project guarantees a solid infrastructure and the operating costs of wells and electric generators will be reduced for nine towns, challenges to ensure the provision of sustainable and continuous water service to all must be addressed.” 

“In the current difficult circumstances Lebanon is experiencing, there needs to be a serious reflection at national and local levels on the challenges facing access to water to ensure sustainability of the service. Responsibility for this lays on everyone”.

“Public commitment to paying due water bills is a cornerstone for water system stability and continuity, with municipalities playing a leading role to encourage the families to subscribe and make the necessary efforts to get water bills paid and with the water establishments ensuring equal access to water for all,” Squarcella added.

Yukie Mokuo, UNICEF Representative in Lebanon, remarked that ongoing access to the public water supply is essential to all communities, especially during these extremely difficult times, where critical services including water and sanitation, power networks and healthcare are under huge strain”. “UNICEF is working closely with the four water establishments in Lebanon, and we congratulate the South Lebanon Water Establishment and the Sabil Consortium for the successful implementation of this critical system thanks to the commitment of the EU, which is consistently working with UNICEF and partners to reach the most vulnerable children and families with safe and clean water,” she said.

Sabil Consortium Representative, Mirdza Abele, explained the technical details of the Consortium’s (Action Against Hunger, Care, CISP, and ACTED) contribution to the project and thanked partners for their support: “We thank the European Union for their complete confidence and support throughout the execution of this strategic and economically sustainable project, South Lebanon Water Establishment for their constant cooperation, and to UNICEF for its contribution by supporting the project.” “We congratulate all those who contributed to the success of this project, particularly the teams of CISP, Action Against Hunger, and Care, for their great efforts and amazing coordination in achieving this project,” she concluded.

South Lebanon Water Establishment’s plan includes three phases, serving three towns on the first phase and expanding to six additional villages on phases two and three. The implementation of these phases depends on the availability of sufficient and sustained funding.




Notes to editors


Technical notes about the project:


  • The Maaroub project provides the solid infrastructure for a reliable water service for all with an adequate volume of water to meet the demand surge. This ensures a strong pillar for the water system in the Southern region, creating an enabling environment for the water establishment to meet the current and future water demand.
  • The two regional reservoirs were equipped with a sustainable energy source by installing and operating a solar-powered electricity production system constructed and fitted on-site to handle control, flow, and management rooms.
  • Connected wells in nearby Yanouh feed the reservoirs through a main pumping line from Yanouh water pumping station that delivers a flow capacity of 214 l/s. UNICEF provided materials and equipment for both and the gravity distribution lines, while the Sabil Consortium carried out excavation works and the installation of the main pumping line from Yanouh to Maaroub (8km with a diameter of 400mm) in addition to the rehabilitation of Yanouh pumping sets and two wells (wells no. 1 & 4) and the distribution lines to the three villages benefiting from the first phase of the project - Maaroub, Al-Hallousiyeh, and Terfilsieh.
  • The Maaroub water system project design is distinguished by its reliance on the principle of pressure balance and gravity pumping, for which the Maaroub regional reservoirs, with a total capacity of 5,000 m3, are mainly supplied by water sources from the Yanouh water pumping station. The pumping volume from this station to the reservoirs was increased to a pumping capacity of 214 l/sec and pumped back by gravity through Maaroub system water to the secondary water distribution networks of the beneficiary villages, with a total production capacity of 18,490 m3.
  • The project will reduce the operating costs of wells and electric generators for nine towns, including maintenance costs. Regional storage and distribution operations will be organized within an advanced control system that is powered by solar energy. In addition to the reservoir, it includes control, operation, and management rooms that have been established and equipped to ensure optimal conditions for the success of the project.
  • The South Lebanon Water Establishment plan requires that the Maaroub water system supply the nine towns over three phases. The first phase is operated and supplied by gravity from the Maaroub reservoirs to the municipalities of Maaroub, Al-Hallousiyeh and Terfilsieh. At a later stage, the second and third phases will connect six additional villages – Deir Qanoun Al Nahr, Abbasieh, Toura, Bidias, Jennata and Burj Rahal— with the Maaroub reservoirs. The implementation of these phases depends on the availability of sufficient funding.
