Sustainable water supply

• What is the focus of sustainable water supply?

  To ensure water resources are used sustainably
• Why are massive engineering works not always the answer to water insecurity?

  They may not provide a sustainable solution
• How can we ensure sustainable use of water resources?

  By using water resources sustainably for everyone
• What are the key strategies for sustainable water supply?

  • Use less and reuse more water
  • Fix leaking reservoirs and pipes
  • Fit dual-flush toilets to save water
  • Buy efficient washing machines
  • Irrigate farmland using drip systems
  • Fit homes with water meters
• What is water conservation about?

  Trying to use less water
• How can dual-flush toilets contribute to water conservation?

  They use less water per flush
• What is the benefit of efficient washing machines?

  They use less water
• How does drip irrigation help in water conservation?

  It directs water exactly where needed
• What is the purpose of fitting homes with water meters?

  To monitor and reduce water usage
• What are the indicators of effective groundwater management?

  1. Monitoring groundwater extraction rates
  2. Ensuring natural replenishment occurs
  3. Implementing laws to prevent over-extraction
  4. Encouraging sustainable agricultural practices
• What can be done to prevent excessive groundwater extraction?

  Passing laws to limit extraction rates
• Why is it important to monitor groundwater extraction?

  To ensure it is not extracted faster than replaced
• How can farmers be encouraged to use less artificial fertilizers?

  By promoting less toxic alternatives
• What happens when groundwater supplies are shared between countries?

  International agreements are needed for management
• What is the role of international agreements in groundwater management?

  To ensure shared supplies are managed fairly
• What type of fertilizers are mentioned in the study material?

  Artificial fertilizers
• What is the impact of artificial fertilizers on farmland?

  They can lead to toxic industrial waste
• What is necessary when groundwater supplies are shared between countries?

  International agreements are needed
• What happens if one country takes an unsustainable amount of water from an aquifer?

  Other countries may struggle to meet needs
• What is a challenge in agreeing on water extraction from aquifers?

  Determining how much water each country should take
• Why is recycling water considered more sustainable?

  It reduces the need for new water extraction
• What does 'Grey' water refer to?


  Recycled water that is reused immediately
• What is the primary use of most recycled water?

  Irrigation and industrial processes
• What is a limitation of using recycled water for drinking?

  It may not be safe enough for consumption

  Irrigation of crops
• How does using recycled water help in drought conditions?

  It provides an alternative water source
• What are the environmental benefits of recycling water?

  It conserves natural water resources
• What is a disadvantage of using recycled water for irrigation?

  It may contain harmful substances
• Why is it important to treat recycled water before use?

  To remove contaminants and pathogens
• How does the use of recycled water impact agricultural practices?

  It allows for more sustainable farming
• What is a key factor in the sustainability of water use?

  Efficient recycling and management
• How can communities benefit from water recycling initiatives?

  By ensuring a reliable water supply
• What is the overall goal of implementing water recycling programs?

  To promote sustainable water management
