How much longer should the length of DI tubing be compared to its width?

The correct length of DI (drainage infiltrator) tubing should be 2 times longer than its width to ensure effective drainage and aeration. This ratio ensures that the tubing's surface area provides adequate flow and meets the necessary hydraulic criteria for efficient wastewater treatment. In septic systems, the design must consider factors such as soil absorption rates and the capacity for filtering effluent, which is supported by having tubing that is proportionally longer than its width.

A length that is twice the width allows for optimal fluid movement and distribution, reducing the risk of clogging and maximizing the system's functionality. This design principle is critical for the longevity and operational efficiency of septic systems, helping to prevent issues that may arise from insufficient tubing length in relation to its diameter.
