Ein Bokek WWTP

Ein Bokek Wastewater Treatment Plant
Advanced wastewater treatment in a unique tourist area along the Dead Sea
Location: Ein Bokek, Hamei Zohar, Neve Zohar – Tamar Regional Council
Project Type: Wastewater Treatment Plant (WWTP)
Client: Tamar Regional Council / Regional Authorities
Project Status: Completed
Balasha Jalon Role: Full design services (preliminary and detailed design)

🟦 Project Overview
The Ein Bokek Wastewater Treatment Plant serves the hotel zones of Ein Bokek, Hamei Zohar and Neve Zohar, as well as the communities of the Tamar Regional Council. The facility was originally constructed in the early 1980s in response to rapid growth in tourism activity in the Dead Sea region.
In the late 1990s, the plant underwent a significant upgrade to accommodate the continued expansion of tourism in the area. Following the upgrade, the WWTP comprised four treatment modules – two original modules and two newly constructed ones.
The project is characterized by a unique engineering challenge associated with the treatment of wastewater with exceptionally high salinity levels, resulting from the plant’s proximity to the Dead Sea.

🟦 Balasha Jalon’s Role
Balasha Jalon Infrastructure Systems Ltd. provided preliminary and detailed design services for both the original construction and the subsequent upgrade of the wastewater treatment plant, integrating all required engineering disciplines.

🟦 Engineering Challenges
The project involved several key challenges, including:
• Treatment of wastewater with exceptionally high salinity concentrations
• Operation of the facility within a sensitive tourist environment
• Adaptation to continuous growth in seasonal wastewater loads
• Compliance with stringent effluent quality requirements for reuse

🟦 Balasha Jalon’s Solution
The solution was based on an integrated design approach, including:
• Implementation of an activated sludge process based on Low F/M – High SRT
• Integration of reliable treatment systems resistant to harsh environmental conditions
• Design of a system enabling reuse of treated effluent for public landscape irrigation
• Provision for future expansions and upgrades

🟦 Project Components – Liquid Treatment

Process Technology:
Activated sludge – Low F/M – High SRT

Main Components:
• Screens
• Grit removal systems
• Oxidation ditches with aeration discs
• Clarifiers
• Effluent filtration and disinfection
The treated effluent is reused for irrigation of public green areas surrounding the hotel zone.

🟦 Project Components – Sludge Treatment

Process Technology:
Aerobic stabilization

Main Components:
• High SRT sludge stabilization basins
• Equalization tank

🟦 Key Design Parameters
• Average daily design flow: 5,100 m³/day
• Average BOD load: 1,700 kg/day
• Effluent quality: 15/15/10 (BOD / TSS / N)

🟦 Project Added Value
The project demonstrates Balasha Jalon’s expertise in the design of wastewater treatment facilities in unique and sensitive environments, providing engineering solutions tailored to extreme climatic conditions, elevated salinity levels, and the operational demands of an active tourist region.
