Bangkok’s Flooding Crisis: A Growing Concern

Bangkok, the capital of Thailand, is highly vulnerable to urban flooding due to its low-lying geography, heavy rainfall, and rapid urbanization. On average, the city receives 1,500 mm of rainfall annually, with peak monsoon months seeing up to 300 mm in a single day. However, its stormwater infrastructure, consisting of approximately 20,000 drainage outlets, is insufficiently maintained, leading to frequent waterlogging.

Recent studies have shown that 30-40% of Bangkok’s stormwater drains are clogged due to accumulated waste and debris. The impact of these blockages is severe:

• $500 million in economic losses annually due to infrastructure damage and disrupted businesses.
• Over 5,000 properties affected by flooding each year.
• Increased risks of waterborne diseases due to stagnant water accumulation.

The Logistical Challenge of Drainage Maintenance

The Bangkok Metropolitan Administration (BMA) has allocated approximately $50 million annually for drainage cleaning and maintenance. However, this traditional approach relies heavily on manual inspections and labor-intensive clearing, which is both time-consuming and costly. Key logistical challenges include:

• Limited workforce: Only 1,200 workers are assigned to maintain the city’s entire drainage network.
• Inefficient reporting system: Residents often report clogged drains after flooding occurs, leading to reactive rather than proactive maintenance.
• Environmental concerns: Heavy machinery and chemical-based cleaning methods have negative ecological impacts on Bangkok’s waterways.

AirLume - The Solution

AirLume technology presents a cost-effective, self-sustaining solution to Bangkok’s drainage issues. By utilizing air and renewable energy sources, our device prevents debris accumulation at storm drain grates, ensuring uninterrupted water flow. Here’s how it works:

• Rain-powered activation: The device operates only during rainfall, reducing energy consumption.
• Air-driven clearing mechanism: Pressurized air removes blockages from the grate surface in real-time.
• Zero maintenance requirement: Unlike traditional sensors that require frequent recalibration, AirLume is self-adjusting and long-lasting.

Long-Term Benefits

By integrating AirLume technology, Bangkok can expect:

• 50% reduction in clogged drains, ensuring smoother stormwater flow.
• $20 million savings in annual maintenance costs due to reduced manual labor.
• Enhanced flood resilience, minimizing disruptions to daily life and economic activity.
