Extension /Public Tender announcement Nbr 91190462 Mobile waste water treatment laboratory PN#16.2090.5-001.00 " Enhancing Water Resource Management" WAMA

Objectives

The overarching objective of this intervention is to enhance Lebanon's wastewater monitoring infrastructure by introducing a fully equipped, stand-alone mobile laboratory housed in a caravan. This self-contained unit will fill critical gaps in analytical capacity and enable real-time, on-site water quality testing at WWTPs currently operating without reliable laboratory access. The caravan labs will rotate between facilities (WWTPs) according to operational priorities and availability, reinforcing timely compliance monitoring and decision-making.

• Support operational wastewater monitoring: Deploy 2 mobile caravan laboratory capable of autonomous field operation, designed to be easily towed to WWTP sites across diverse geographic and operational contexts.
• Enable routine and decentralized testing: Establish a consistent field-testing routine to support influent and effluent monitoring in accordance with Lebanese regulatory and operational standards.
• Ensure compliance with Lebanese ELVs: Provide instrumentation and protocols to measure all key physio-chemical parameters required for alignment with Lebanese ELVs, reinforcing environmental and legal compliance.
• Detect process deviations and enable timely corrective actions: Improve the ability of WWTP operators to detect operational parameters early on, enabling them to quickly diagnose potential process faults and implement effective corrective measures before regulatory thresholds are exceeded.

Build institutional capacity within WEs: Use the mobile labs as a hands-on training platform to develop the skills of WE staff in laboratory 

• methods, quality assurance, reporting, and environmental monitoring practices.
• Accelerate data-driven decision-making: Enable rapid turnaround of analytical results at the site level to support immediate operational adjustments and reduce dependence on remote laboratory resources.
• Establish a scalable and replicable model: Demonstrate a flexible and cost-effective solution for wastewater monitoring that can be expanded to other regions or utility contexts.
• Promote safety and environmental accountability: Integrate robust safety features (e.g., ventilation, PPE protocols, spill containment, emergency systems) and ensure that monitoring results inform corrective action and institutional accountability.
• Protect public health and surrounding ecosystems: Allow timely identification of non-compliant discharges, support early mitigation responses, and safeguard aquatic and human environments.

Specific Objective

This mobile laboratory will serve as a cornerstone for strengthening wastewater sector performance, supporting Lebanese compliance frameworks, and institutionalizing high-frequency monitoring and technical autonomy across the Water Establishments.

Structure of the Tender (Lots)

This tender is structured into two separate lots, each covering a distinct scope of services. Bidders are invited to submit offers for one lot only or for both lots, depending on their interest and demonstrated capacity. Each lot will be evaluated individually based on the technical and financial criteria defined in this ToR. GIZ reserves the right to award the lots either separately to different contractors or jointly to a single contractor, depending on the outcome of the evaluation and in accordance with the principles of efficiency, transparency, and best value for money.

Contractors submitting offers for both lots must ensure that their proposals clearly distinguish between the two lots, with separate technical and financial documentation provided for each.
