General Drip Design Definitions
Control
Electromechanical operational interface device used to operate the system. Automatic control is operation without human physical actions. Manual control operation is the operation of a system which bypasses or is not performed by automatic equipment.
Draindown
The action of effluent left in the distribution system after the pump shuts off that drains by gravity to the lower lines in the system.
Dripper Line Loading Rate
The amount of contaminants dispersed by the dripper line. This material shall be described in generally accepted engineering units such as gallons per day of water and pounds per day of contaminant (BOD, FOG, Solids, etc.)
Field Flushing
The routine maintenance act of cleaning drip tubing by opening the end of a lateral and creating scouring velocities in the same direction of flow in the tubing to remove solids which may plug an emitter.
Flow Equalization
Storage of effluent peak flows to provide for even time dosing of dripper lines. It is designed into system by distance between the enable float and the alarm float.
Lateral
One run or a series of runs connected at one end to a supply manifold and the other end connected to a return manifold.
Mechanical Filtration
Mechanical filtration of the applied effluent to prevent emitter plugging.
Monitoring
Periodic inspection of system for performance.
Pretreatment
Conditioning of effluent prior to dispersal by drip system.
Return Manifold
The pipe carrying field flushing wastewater from a zone.
Run
One continuous length of tubing run across contour connected to a supply line or return line or another run.
Standoff
The vertical and horizontal separation distance from receiving environment limitations.
Supply Manifold
The supply pipe feeding a zone to which laterals are connected.
Zone
A group of laterals dosed at the same time.
