Class IX Practical: Field Visits - Water/Sewage Treatment Plants or Vermicomposting Sites

Objective

To visit a water treatment plant, sewage treatment plant, or vermicomposting site to study their functioning and importance.

Guidelines

1. Site Selection & Permission: Choose one type of facility (Water Treatment Plant, Sewage Treatment Plant, or Vermicomposting Site) and obtain necessary permissions for a visit.
2. Observation & Data Collection:
   • Water/Sewage Treatment Plant: Observe the different stages of treatment (e.g., screening, sedimentation, filtration, chlorination for water; primary, secondary, tertiary treatment for sewage). Understand the purpose of each stage and the machinery involved. Note the input and output quality.
   • Vermicomposting Site: Observe the setup of vermibeds, the types of earthworms used, the raw materials for composting, and the process of converting organic waste into vermicompost. Understand the role of earthworms.
3. Interaction: Interact with the facility staff to gain insights into the processes, challenges, and benefits.
4. Note-Taking: Take detailed notes, sketches, or photographs (if permitted) of the processes and equipment.
5. Report Preparation: Prepare a detailed report on the visited site, including:
   • Introduction: Type of facility, location, purpose of visit.
   • Description of Processes: Step-by-step explanation of the functioning of the plant/site.
   • Key Components/Machinery: Description of important equipment.
   • Significance: Explain the environmental and societal importance of the facility.
   • Conclusion: Summarize key learnings.

Expected Outcome

A comprehensive report demonstrating an understanding of the functioning and environmental significance of water/sewage treatment or vermicomposting processes.
