How can buildings reduce pressure on city-wide water infrastructure?
W09 ? ONSITE NON-POTABLE WATER REUSE | OPTIMIZATION
Buildings can reduce pressure on city-wide water infrastructure by minimizing the use of municipally sourced water for applications that do not require potability, such as irrigation and flushing toilets.

What are some key aspects of designing and operating a healthy non-potable water system?
W09 ? ONSITE NON-POTABLE WATER REUSE | OPTIMIZATION
Key aspects include treating and monitoring water quality before reuse, ensuring water capture and reuse does not create stagnation, performing periodic checks on storage tanks, avoiding commingling of potable and non-potable water pipes, and managing smells and odors to avoid health perception issues.

What is required in the safety plan for non-potable water systems regarding key team roles?
W09 ? | Part 1 Implement Safety Plan for Non-Potable Water Capture and Reuse
The safety plan must include a list of key team roles for design, operations, maintenance, and third-party inspection of the non-potable water system.

What must the safety plan describe to ensure protection against pathogen exposure?
W09 ? | Part 1 Implement Safety Plan for Non-Potable Water Capture and Reuse
The plan must include an analysis of how human exposure to pathogens through ingestion and inhalation is minimized, including strategies for cross-connection control and backflow prevention.

What should the process flow diagram in the safety plan display?
W09 ? | Part 1 Implement Safety Plan for Non-Potable Water Capture and Reuse
The diagram must display non-potable water sources, conveyances, storage units, treatment devices, and points of use, emphasizing where makeup potable water may be added.

What information must be documented annually through the WELL digital platform?
W09 ? | Part 1 Implement Safety Plan for Non-Potable Water Capture and Reuse
Projects must submit documentation of the startup procedure, maintenance logs, results from verification tests (when applicable), and third-party inspections.

How must non-potable water systems be distinguished for occupants?
W09 ? | Part 1 Implement Safety Plan for Non-Potable Water Capture and Reuse
Projects must provide visual evidence of conspicuous signage to clearly distinguish potable from non-potable water and informative displays highlighting the safety features and conservation goals of the system.
