What is the minimum liquid depth for a type III interceptor?

The minimum liquid depth for a Type III interceptor is 24 inches, which is crucial for its effective operation. Type III interceptors are specifically designed to separate and remove oils, greases, and other floating materials from wastewater. This depth ensures adequate retention time for the wastewater, allowing for the proper settlement of solids and the floating of grease.

With a minimum depth of 24 inches, the interceptor can maintain a level of separation efficiency that reduces potential clogging in downstream plumbing, protects the municipal sewer system, and ensures compliance with environmental regulations. A shallower interceptor may not provide sufficient space for the proper functioning and settling processes, potentially leading to ineffective treatment and increased risks of backups or overflows.

Therefore, adherence to the 24-inch minimum liquid depth in a Type III interceptor is essential for the system's overall effectiveness and reliability in handling wastewater.
