Terms of Treatment

Distribution, sequential: Distribution method in which effluent is loaded into one trench and fills it to a predetermined level before passing through a relief line or device to the succeeding trench. The effluent does not pass through the distribution media before it enters succeeding trenches.

Distribution, serial: Distribution method in which effluent is loaded into one trench and fills to a predetermined level before passing through a relief line or device to the succeeding trench. Effluent passes through the distribution media before entering succeeding trenches, which may be connected to provide a single uninterrupted flow path.

Distribution, low pressure: (1) Application of effluent over an infiltrative surface via pressurized orifices and associated devices and parts (including pump, filters, controls, and piping). (2) Distribution via a network of small diameter laterals (typically 1 1 / 4 -inch) with small orifices (typically 1 / 8 to 3 / 16 -inch) installed in a soil treatment area.
