Difaf is an environmental solutions provider and a technical design bureau born in Lebanon in 2014. The company is the product of its founders’ passion for environmental protection and for restoring degraded ecosystems. Our guiding principle is to improve the conditions of our water and environmental systems by promoting feasible interventions, green technologies, and ensuring project sustainability.
Difaf's approach to development is based on circular economy principles, participatory methods, and nature-based resiliency. Our decentralized solutions are therefore tailored, cost-effective, and in-line with natural processes. We guarantee to integrate these elements in all of our works as we consider them precursors to the success of truly green projects.

Technical Assistance for Wastewater Treatment Design & Installation (2019)Difaf was approached by ACF in order to execute an upgrade plan of the existing wastewater treatment plant, designed by ACF, with the collaboration of the Ministry of Environment. Difaf upgraded a tank into a trickling filter and incorporated into the system design an H2S removal system. Difaf was responsible for the procurement, installation and commissioning of the required items.
Geotechnical Study & Lake Designs to Increase Water Storage Capacity (2014)Difaf carried out an extensive study assessing the geotechnical aspects related to increasing the water storage capacity at Domain Taanayel, Bekaa, by either increasing the storage capacity of the existing lake and/or constructing additional reservoirs next to the existing lake. The end product was a complete design for building an oval lake and constructing a large earth reservoir. Difaf also supervised the implementation and monitored its success.
Water and Sanitation (WASH) Infrastructure & Needs AssessmentDifaf completed a comprehensive WASH needs assessment survey, evaluating the technical status of the water supply and wastewater infrastructure, prioritizing interventions according to a needs assessments for twelve refugee gatherings located within or around the Tyre Caza, Lebanon.
End-of-Program Evaluation for Intaj III - Solid Waste Management (2019)Difaf conducted an end of program evaluation for the program “Improved Networks, Training and Jobs (INTAJ III)” led by Mercy Corps and funded by DFID, with the evaluation focusing on the impact of the program and its outcomes on the target population of the regions of Chouf Souaijani, Iqleem al Kharoub, and Minnieh, mainly regarding solid waste management and recycling (SWM/R), and management and implementation processes. The evaluation lead to providing recommendations for the next phase of program implementation (FY 2019-2021) and its possible scale-up. The project goal was the improvement of stability and SWM/R service delivery while reducing grievances and improving perceptions and trust between community members in Lebanon.
Wastewater Treatment Solutions for Small Dairy Industries (2018-2019)Difaf was commissioned to assess, sample analyze effluent wastewaters from small-scale dairy industries and recommend appropriate treatment technologies tailored to the various contexts of the industries in Bekaa. Difaf will also be responsible of supervising the implementation of the technologies as well as commissioning procedures.
Establishing a Wastewater Treatment Monitoring Unit in the Bekaa Water Establishment (2018-Present)Difaf is leading a ten-month assessment, training and institutionalization of a wastewater treatment unit in the Bekaa Water Establishment. The aim is to empower and structure this unit in order to be able to continuously evaluate and monitor the status and functionality of the various wastewater treatment plants in the Bekaa region, as well as recommend solutions and optimization activities.
Ghzayyel River Flood Risk Assessment (2019)Difaf was commissioned to conduct a flood risk assessment of Ghzayel River (tributary of the Litani River) with the main benefit being the development of a site-specific riparian rehabilitation plan over the 25 km stretch of the river. Difaf developed a hydrological study and a hydraulic model of the river based on topographic data and hydrological information on the watershed. This model was used to map the flood-plain for different flood return periods and develop a flood risk assessment report for the area including recommendations and mitigation measures to be applied for the riparian rehabilitation project which will be designed and implemented by LRI.
Ostwane River Restoration (2017)Difaf successfully performed a full-scale erosion assessment of the banks of a tributary to River Ostwane and developed an erosion control plan using hard and soft engineering methods for each section. Difaf also designed and implemented erosion control and riverbank restoration methods using rip-rap, coir rolls, and revegetation of banks using herbs and trees.
Technical Guidelines for Water Extraction around Protected Areas in LebanonDifaf was commissioned to develop technical guidelines and policy recommendations for the Ministry of Environment to oversee the permit applications for water extraction in buffer zones of protected areas (all 15 nature reserves) in Lebanon.
