If a Class 4 system is proposed, should you ask the property owner if there are any future additions or structures planned for the property?

• A. Yes
• B. No
• C. Only If Asked
• D. It Depends On Property Size

Answer: (A)

When designing a Class 4 on-site system, you must consider potential future additions or structures on the property. The reason is that future growth can change the wastewater load and how the system must perform over its life. By asking the property owner about planned expansions, you can determine if the design should be sized to handle increased flow, adjust the layout to protect the absorption area, or plan for expansions that won’t require a full redesign later. This proactive step helps ensure the system remains compliant and functional as the property changes, avoiding undersized capacity or costly retrofits later on. If you don’t ask, you risk designing for today’s conditions and quickly outgrowing the system. It isn’t about the property size; future plans can affect systems on any site.
