Tenders Are Invited For Optimization Of Water Distribution System Through Pump Replacement And Solar System Reconfiguration

Tenders are invited for Optimization of Water Distribution System through Pump Replacement and Solar System Reconfiguration. Closing Date: Saturday, 31. May 2025 Intervention Sector(s): Water sanitation and hygiene Michel Daher Social Foundation (MDSF), established in 2014, is a Lebanese NGO dedicated to addressing the unique challenges faced by communities in Central Bekaa. Committed to creating an environment where individuals can achieve their highest potential, the foundation focuses on community health care, economic and human capacity building, sustainable community development, and livelihood. MDSFs mission is rooted in providing support to help people overcome life challenges and to make a positive impact on the Bekaa community. Project Overview: The project aims to increase access to safe and reliable water services among communities in Zahle Caza, Lebanon, with a focus on improving the capacities of the Bekaa Water Establishment (BWE) and enhancing water services for the upstream and downstream communities of Jdita. Thethe project includes technical and material capacity strengthening, community engagement, facilitation of allocation agreements, and activation of the regional water network. Scope of Work Water and Solar Systems Reconfiguration As the current status of the facility stands, the water distribution is directly from the pumps to the consumers, this configuration requires more energy to drive the water towards the end- user. However, with the existing water tank available at the facility, another configuration can be implemented, where the pumps drive the water towards the tank and then redistributed it towards the end-user with the assistance of the potential energy (gravity). By using the water tank as the main distribution unit, the existing submersible pumps can be reduced to ones with a smaller power rating. Pump 1 will be replaced by a 120 HP (90 kW) pump, whereas Pump 3 can be replaced by two 100 HP (75 kW) pumps, thus reducing their energy usage. The outcome of such a reconfiguration will provide near-full autonomy to 2 pumps. To cover the replacement of the pumps with smaller-rated units, the solar pumping system will need to be redesigned to support them. Currently, the existing solar pumping system size is 273 kWp: this system shall be reconfigured to be able to supply both pumps. This reconfiguration should include two VFD (one VFD is needed per pump) and the reconfiguration of wiring in the existing solar pumping system, including wiring and electrical boards. The system primarily utilizes solar energy, switching to EDL and diesel generators when necessary.
