1. Introduction
BPM (The Best Project Material Co., Ltd) is a leading manufacturer of geosynthetics, specializing in high-quality Composite Geomembrane solutions. This case study demonstrates how our product successfully addressed a major leakage issue at a water reservoir project in Southeast Asia.
2. Client Background
A government water management agency in Indonesia was struggling with chronic leakage in a critical irrigation reservoir. The existing lining system had failed due to UV degradation and poor seam strength. They needed a reliable, long-term solution to prevent water loss and soil contamination.
3. The Challenge
Reservoir area: 25,000 m²
Depth: 8 meters
Problem: 30% water loss due to liner failure
Requirements:
UV-resistant material
High puncture resistance
Minimum 20-year lifespan
4. Why Composite Geomembrane?
BPM recommended our Composite Geomembrane because:
Superior Strength: Combines geotextile backing with HDPE membrane for extra durability
Excellent Seam Integrity: Special welding technology prevents leakage at joints
UV Protection: Contains carbon black additives for sunlight resistance
Cost-Effective: Longer lifespan reduces replacement costs
5. BPM’s Solution
We provided:
Material: 2.0mm thick Composite Geomembrane with:
Tensile strength: 28 kN/m
Puncture resistance: 500 N
Carbon black content: 2.5% for UV protection
Installation Support: Sent technical team to supervise installation
Quality Assurance: Provided third-party test reports (ASTM D6392, ISO 9001)
6. Implementation Process
Site Preparation: Our team helped level the reservoir base
Installation: Used thermal welding for all seams
Testing: Conducted spark testing on all welds
Completion: Project finished 2 weeks ahead of schedule
7. Results & Benefits
After 18 months of operation:
Zero Leakage: No water loss detected
Cost Savings: Reduced water pumping costs by $15,000/month
Environmental Protection: Prevented soil erosion and contamination
Client Satisfaction: “BPM’s Composite Geomembrane outperformed all our expectations” – Project Manager
