Technical FAQs:
- All water, including reclaimed rain water, being used in situations that do not lead to human contact are not required to meet the water quality requirements.
- According to WELL Performance Verification Guidebook, water for human contact is conducted on cold water.
- If the restrooms are outside the WELL project boundary, the project is not required to meet the water quality requirements at these locations. Performance testing would only occur in fixtures within the project space. However, if the tenant space does not have a drinking fixture, the next closest fixture would be tested (for example: bathroom fixtures outside of the project boundary).
