Field notes
The comparison table exposes several operational differences between jurisdictions, including pump-out intervals, minimum interceptor sizes, and permit requirements. The page also distinguishes hydromechanical traps from gravity interceptors and points readers to sizing methods including PDI G-101; the extracted homepage does not confirm how the interactive calculators behave.
