Band 8 Strategy Framework for Water Content

1. Water System Reading Approach

  • Identify system type: Natural cycle, treatment process, or distribution network
  • Recognize flow patterns: Direction and sequence of water movement

  • Treatment terminology: Filtration, sedimentation, disinfection, purification
  • Infrastructure vocabulary: Reservoir, pipeline, pump station, storage tank
  • Environmental concepts: Watershed, aquifer, contamination, conservation

Example Walkthrough: Water Treatment Plant Process

Sample Passage Extract:

"Municipal water treatment follows a systematic multi-stage process to ensure safe drinking water. Raw water first enters the intake structure where large debris is removed through basic screening. The water then flows to the sedimentation tanks where suspended particles settle to the bottom. Following this, the water passes through sand filtration systems that remove smaller contaminants. The final stage involves chlorination to eliminate harmful bacteria and viruses before distribution..."

Practice Example: Urban Stormwater Management

Passage Context:

"Modern cities employ sophisticated stormwater management systems to prevent flooding and protect water quality. Rainfall is first collected by storm drains throughout the urban area. This water flows through underground conduits that transport it away from populated areas. Before discharge, the stormwater enters retention ponds where sediments settle and pollutants are filtered. Finally, the treated water is released into natural waterways where it rejoins the broader hydrological system..."
