<p>Scope: Integrated solid waste management system incorporating two sanitary landfill sites in former quarries - Naameh (south of Beirut) and Bsalim (north of Beirut). Design validation per British standards, construction supervision, and operation/maintenance oversight. Impermeable composite lining, comprehensive environmental control systems: leachate collection and treatment, landfill gas control, surface water management and monitoring, groundwater and air quality monitoring. ~11 million tons of waste from Greater Beirut Area and Mount Lebanon (50% of Lebanon's population) over 18 years. Final capping with hydroseeding vegetation ongoing at Naameh. Biogas conversion to electrical power supplied to nearby villages. EIA studies, contract management on behalf of CDR.<br>Challenge: Achieve three CDR objectives: control chaotic waste management situation in Beirut following civil war end, ensure landfill sites designed, constructed, and operated per British standards (most stringent globally), and control environmental impacts throughout project lifecycle. Naameh landfill location in valley within old quarry added significant complexity requiring extensive infrastructure works. Manage politically sensitive waste facility serving 50% of country's population in post-war environment with limited institutional capacity.<br>Approach: EIA studies identified potential impacts and recommended mitigation measures. Controlled and validated design development process ensuring British codes and standards compliance - most stringent sanitary landfill requirements globally. Supervised and controlled construction activities quality throughout implementation. Supervised day-to-day operation and maintenance activities over 18-year operational period. Ensured environmental monitoring practices implementation - leachate treatment, gas control, surface/groundwater monitoring, air quality monitoring. Managed contract on behalf of CDR client. Naameh valley/quarry location necessitated extensive infrastructure works successfully delivered despite complexity. Biogas produced converted to electrical power supplied to nearby villages - converting environmental liability into community benefit.<br>Status: 18-year operation completed, final capping works ongoing at Naameh with hydroseeding vegetation</p>
Solid waste management
Construction supervision
Laceco responded to the above objectives by:
Designing a consistent urban framework that nevertheless provided a diversity in the individual architectural character of buildings.
Curating a seamless pedestrian experience in a site that had a challenging topography and was exposed to dominant winds.
Anchoring the site along three platforms linked to each other by a continuous game of terraces, stairs, suspended bridges and esplanades that gently slope down the length of the development.
Conducting value engineering and cost optimization studies to preserve economic viability of the development.
Laceco responded to the objectives by:
Preparing EIA studies to identify the potential impacts and recommend the necessary mitigation measures.
Controlling and validating the design development process to ensure compliance with British codes and standards.
Supervising and controlling the quality of construction activities.
Supervising day-to-day operation and maintenance activities.
Ensuring the implementation of environmental monitoring practices.
Managing the contract on behalf of the Client.
Interesting facts:
The British standards are the most stringent when it comes to sanitary landfills design.
The Naameh landfill location in a valley within an old quarry site added a challenge and a complexity level to the design process and necessitated extensive infrastructure works.
The biogas produced from this landfill is converted to electrical power that is supplied to the villages in the vicinity of the landfill.
