- B) Yes — collaborative actions at the watershed or basin level are valuable and disclosable ✓
- C) Only if the company is a water utility
- D) Only if required by local government
Explanation: Water is a shared resource; watershed-level engagement (e.g. with communities, other users, regulators) demonstrates stewardship.
Q2.5 A company invests in rainwater harvesting for non-potable uses. Under E3-2, this is:
- A) Not a valid water action
- B) A valid action that reduces dependence on freshwater withdrawal ✓
- C) Only relevant for agricultural companies

Q2.7 Which water action has the highest priority in the water management hierarchy?
- A) Wastewater treatment before discharge
- B) Reducing water demand at source (efficiency, process redesign) ✓
- C) Increasing storage capacity
- D) Securing additional water supply
Explanation: Demand reduction at source is the highest-priority approach, analogous to the pollution prevention hierarchy.
Q2.8 A company in a water-stressed region invests in desalination. Under E3-2, this is:
- A) A sustainability failure
- B) A valid supply-side action, but the disclosure should also address demand reduction and the energy implications of desalination ✓
- C) The preferred water management approach
- D) Not reportable under E3
Explanation: Desalination secures supply but is energy-intensive; a balanced disclosure addresses both supply and demand actions.
Q2.9 Actions to improve the quality of wastewater discharge are:

- B) Was removed — companies report absolute figures only ✓
- C) Was made mandatory
- D) Was changed to revenue-based only
Explanation: The intensity metric was removed, simplifying reporting to absolute volumes.
Q4.10 A water balance for a facility shows: Withdrawal 500 ML, Discharge 350 ML, Recycled 200 ML. What is the consumption?
- A) 500 ML
- B) 150 ML (500 - 350) ✓
- C) 700 ML (500 + 200)
- D) 200 ML
