What maximum variation in orifice discharge rates is acceptable over the entire pressure distribution system?

The maximum acceptable variation in orifice discharge rates in a pressure distribution system is set at 15%. This standard ensures that the system operates efficiently and effectively, allowing for uniform distribution of liquid within the septic system. Consistent discharge rates are critical for preventing overloading or underloading any given area within the distribution network. If the variation were to exceed this threshold, it could lead to localized saturation and ineffective treatment processes, ultimately compromising the entire system's performance and efficiency. Therefore, maintaining this 15% maximum variation is essential for the longevity and reliability of the septic system.
