Creating a rainwater harvesting working model using a plastic tray to collect rainwater, another tray for storage, a DC water pump, and a 9V battery is a practical and educational project.
Here’s a step-by-step guide to help you build this model:
Materials Needed
- Plastic trays (at least two)
- DC water pump
- 9V battery
- Flexible plastic tubing (to connect pump and trays)
- Small stones or gravel (for filtration)
- Mesh or cloth (for filtration)
- Hose connector (if needed for tubing)
- Hot glue gun or waterproof adhesive
- Scissors
- Ruler
- Marker
- Decorative materials (optional, for aesthetics)

1. Prepare the Collection Tray
- Collection Tray Setup:
- Choose a large, shallow plastic tray to collect rainwater. Ensure it has enough surface area to capture sufficient rainfall.
- Drill or poke small holes near the edges of the tray to connect the flexible tubing.
- Filtration System:
- Place a layer of mesh or cloth over the holes to prevent debris from entering the tray.
- Add a layer of small stones or gravel on top of the mesh for additional filtration.
2. Setup Water Storage and Pump
- Water Storage Tray:
- Place another plastic tray adjacent to the collection tray to store the harvested rainwater.
- Connect the storage tray to the collection tray using flexible plastic tubing.
- Ensure the tubing reaches from the collection tray to the bottom of the storage tray to allow water to flow down under gravity.
- DC Water Pump Installation:
- Mount the DC water pump inside the storage tray using a hot glue gun or waterproof adhesive.
- Connect one end of the flexible tubing to the outlet of the water pump.
- Ensure the tubing is securely attached to prevent leaks.
3. Connect Battery and Test
- Battery Setup:
- Connect the wires from the DC water pump to the 9V battery.
- Use wire cutters/strippers to expose the ends of the wires and secure them with tape or connectors.
- Testing the System:
- Place the entire setup outdoors or simulate rainfall using a watering can to fill the collection tray with water.
- Turn on the 9V battery to activate the water pump.
- Observe how the pump moves water from the storage tray through the tubing to simulate irrigation of an agriculture field or garden.
By following these steps, you’ll create a functional rainwater harvesting working model using plastic trays, a DC water pump, and a 9V battery.
