Interceptor 002 & 005
Pioneering Advanced Waste Interception in Malaysia
Developed by The Ocean Cleanup, the Interceptor is a fully solar-powered river cleaning technology designed to extract plastic and solid waste.
The deployment of the Interceptor system in Malaysia marked a significant milestone in advancing river rehabilitation technologies within the country. Sungai Klang was selected as a priority river for implementation due to its strategic importance as a major urban river system, high pollution load from upstream urban activities, and critical role within Selangor’s economic and development corridor.
Recognising these factors, LLSB — through its mandate under the Selangor Maritime Gateway (SMG) — facilitated the adoption and deployment of the Interceptor system as part of a broader, integrated river rehabilitation strategy.
How it Works
Solar-Powered Waste Extraction
River Deepening and Widening
Dredging operations to increase the river's capacity and improve water flow, reducing the risk of overflow during heavy rainfall.
Riverbank Strengthening and Bund Construction
Construction of protective barriers along the riverbank to manage overflow during periods of heavy rainfall and prevent erosion.
Hydraulic
Optimisation
Optimisation of river flow using SPS technology to improve the overall performance of the river system and reduce flood risks.

As of 2025
- ✓A total of five log booms remain in active full-time operation.
- ✓Log Boom Kinrara has been decommissioned due to land-related constraints.
- ✓Log Boom Mini Taman Sentosa operates on an as-needed basis, given the relatively low volume of waste in its designated area

Log Boom System
The Log Boom System is a hydraulically engineered river management solution designed to intercept, control, and consolidate floating debris across upstream and midstream river environments. As part of LLSB’s Integrated River Management System (IRMS), the Log Boom functions as a strategic containment and flow-guidance mechanism, ensuring efficient waste capture while maintaining optimal river flow dynamics.
From Passive Barrier to Engineered Solution
Unlike conventional floating barriers, LLSB’s Log Boom System is developed through hydraulic flow analysis and engineering studies, allowing each installation to be customised based on river-specific conditions:
- ✓Flow velocity and discharge patterns
- ✓River geometry and width
- ✓Tidal influence and water level fluctuation
- ✓Waste load distribution and movement behaviour
Key Capabilities
- ✓Captures up to 800–900 metric tonnes of waste per month
- ✓Directs and consolidates floating debris for controlled collection
- ✓Adapts to dynamic river conditions, including high-flow and tidal environments
- ✓Enables strategic placement across upstream pollution sources

Measurable Results
Since the implementation of SMG river rehabilitation efforts, water quality has shown measurable improvements — from Class V (highly polluted) to Class III (suitable for Irrigation & Fishery of Common species).
57%
of recorded days showed water quality at Class III or above in 2025, reflecting a positive shift in overall river conditions.
