Does a DIS require a chemical injection port?

A Distribution Inlet System (DIS) in a septic system is designed to evenly distribute wastewater among various components of the system, promoting efficient treatment and preventing overload. The inclusion of a chemical injection port can play a crucial role in maintaining the overall health of a septic system.

Including a chemical injection port is recommended as it allows for the introduction of necessary chemicals that can help in maintaining the biological processes essential for breaking down solids and preventing issues such as clogging or odors. These chemicals can also aid in the treatment of the effluent before it reaches the drain field, supporting regulatory compliance and enhancing system longevity.

While it’s important to acknowledge that not every system may require a chemical injection port depending on specific circumstances or regulations, having it as a standard recommendation serves the function of supporting optimal performance of the septic system in most cases. This option reflects a broader understanding of septic system management practices that prioritize both effectiveness and regulatory compliance in Illinois.
