DRIP SYSTEM OPERATION
The system control panel is equipped with three float switches and controls the timed doses to be discharged. The water level must be high enough to overcome the "Redundant Off" (Bottom) float in order for the pump to run. When the water level rises high enough to overcome the "Dose Enable" (second) float and the timer is in a dose enable mode, the cycle will initiate. The pump will activate, automatically backflush the disk filters, then dose the lead zone. The pump will continue to run for the length of time as set on the pump run timer to provide a complete dose. The system will remain off until the preprogrammed off timer enters a new cycle enable mode. At that time the control will activate another cycle and dose the new lead zone (as long as the "Dose Enable" float is still up). This process will continue until the water level drops below the "Dose Enable" float and the pump run timer has timed out. Each zone will automatically receive a field flush each 50 cycles to clean the drip tubing.
If the water level rises enough to overcome the "High Level" (third) float, the audio/visual alarm will be activated until silenced by pressing the Test-Normal-Silence switch to the silence position. The alarm circuit must be manually reset when the "High Level" float returns to its normal position.
Pressure Compensating Dripperline for Wastewater
The dripperline for wastewater is used for both surface and subsurface effluent disposal and recharge. American uses the perfect hydraulic delivery system, considered to be the world's most accurate pressure compensating dripperline. The patented self-flushing, free-floating diaphragm cleans itself during operation. The drippers are located every two feet in the 1000 foot rolls and provide 0.61 gallons per hour per emitter. In most applications the tubing is placed two feet on center providing one emitter for every four square feet of total area.
This is an aireal view of a shopping center system in Maryland with 6 different shaped zones to work around a road, well and pond.
Where is the drip field? Even when the other grass is dormant, drip systems promote crop uptake.
This large flow system in Virginia is an open farm field with good slope. Little site disturbance helps control erosion during installation.
This contractor in Delaware developed his own five gang plow for large system installation.
Large flat sites are conductive to multi-plow installation.
When dealing with any sloping site, such as this one Virginia, the draindown after the pump shuts off can be controlled by a top feed manifold layout.
Ditches need to be wide enough to work in, but don't need to be excessive.
This view shows the far end (the last return) of a system.
Zone valves feed from the bottom of a zone, but the manifolds are located at the top.
