Where should signage be placed when irrigating with reclaimed water?

• A. On the controller
• B. Not required
• C. On the main valve
• D. Around reclaimed pond

Answer: (D)

When irrigating with reclaimed water, the main practice is to clearly identify non-potable water at its source so everyone knows it isn’t for drinking and to prevent cross‑contamination. Signage belongs around the reclaimed pond because that area marks the source of the reclaimed water and is the most visible place people will encounter the water before they approach the irrigation system. Placing signs here ensures immediate awareness for anyone near the water, from operators to maintenance workers, and helps meet safety and regulatory expectations for warning about non-potable water. Signs on a controller or main valve don’t alert people who are approaching the water source, and saying signage isn’t required isn’t accurate. Placing signs around the pond provides clear, early communication about the water type and helps protect workers and the public.
