Rain Water Harvesting Geomembrane Pond
- Geomembrane Material: High-Density Polyethylene (HDPE) – widely used due to its durability, resistance to UV degradation, and excellent chemical stability.
- Geomembrane Thickness:
- For small ponds: 0.8mm
- For large ponds or high-stress areas: 1.2mm
- For small ponds: 0.8mm
- Liner Protection Layer:
- Geotextile fabric – placed between the soil and geomembrane to protect it from punctures and improve stability.

- Pond Shape:
- Trapezoidal – common design for maximizing storage capacity while maintaining structural stability.

- Slope Design:
- Gentle slope on the sides to facilitate water flow and prevent sediment build-up.

- Drainage System:
- Inlet pipes – to channel rainwater into the pond.
- Outlet pipes – controlled release of stored water.

- Overflow Mechanism:
- Spillway – to prevent overtopping during heavy rainfall.

- Water Storage Capacity:
- Calculated based on the pond dimensions and desired water usage.
