| PERC-RITE® DRIP DISPERSAL DESIGN INFO |
- The PERC-RITE® DRIP SYSTEM CONTROLLER is a "state of the art" control panel, activated by level sensing devices (standard mechanical differential float switches) located in a dosing tank downstream from the pretreatment process or processes. When activated by the rising level of effluent in the dosing tank, the controller will enable the disposal cycle. The system controller on a time clock basis will pump the effluent through the filter module and then to final drip dispersal.
- FILTER MODULE - Disc filters, automatic control valves, solenoid activated diaphragm valves, the flow meter are assembled in a heated enclosure and provided with a labeled wire harness for easy connection the the control panel.
- PUMP SYSTEM - The pump, Cool GuideTM and float switches for level
indication are provided for installation into the pump tank. The pump is a turbine 15 gpm pump and will be suitable for most residential installation. Reference lift and run table for
pumping limits.
- DRIPPER TUBING - The dripper tubing is pressure compensating dripperline for wastewater. The tubing delivers a nominal 0.65 gallons per hour (+/- 5% flow rate from 7 to 60 psi). The tubing functions as a turbulent flow emitter between 0 and 7 psi, ensuring that the nominal design flow is not exceeded at system start-up. The tubing is polyethylene with a 120 psi pressure rating.
- TOP FEED MANIFOLD SYSTEM - The Top Feed Manifolds are located at the highest point in the drip zone and provided with air release valves to prevent drain down of upper laterals in the zone to lower laterals in the zone, thus preventing saturation of the lower laterals after the pump shuts off. The system provides for the fastest possible pressurization of the zone and the most efficient method of providing drain down control. If the site is flat, Top Feed Manifolds may not be required.
Patent No. 5,984,574.
- SPECIAL FIELD MATERIALS - All special drip fittings and equipment are supplied by American Manufacturing Company, Inc. including the tubing insert fittings, connectors, flex tube and non- schedule 40 PVC standard fittings.
- STANDARD FIELD MATERIALS - All tanks, wire, standard pipe and fittings are provided by the contractor at the local site. The 1" supply and return pipes, the 1/2" pipe for installation between the top feed manifold system and the laterals and other misc. PVC pipe are to be purchased locally.
OPERATION
The system control panel is equipped with four 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 dose enable mode the cycle will initiate. The pump will activate and automatically backflush the disc 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 which 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.
The control system is equipped with a peak enable circuit to manage peak flows and excess water use event. If the water level rises enough to overcome the “peak enable” (third) float and the peak enable selector switch is on, the system will be cycled at the peak rate. The system will continue to cycle at an increased rate until the peak enable float is deactivated at which time the system will resume the normal dosing cycle.
In the event the water level continues to rise enough to overcome the “High Level” (fourth) float, the audio/visual alarm will be activated until silenced by pressing the Test-Normal-Silence switch to the silence position.

This information and the tables are exerpts from the "Perc-Rite® Drip System Designer's Guide" for the non-engineer designer. Procedures have been developed to size, layout and design a Perc-Rite® Drip system using tables instead of performing calculations. When advanced system design is required the designer must reference the design manual located on our web site and complete a detailed calculation sheet to determine suitability. The Perc-Rite® Drip System operates all components automatically including backflushing filters, field flushing, and timed dosing of drip tubing. Only those components which are special to the drip technology are purchased from American, all other items are purchased locally for better economy.

ZONE DETAIL NUMBERING SYSTEM
Each zone is designated by a "Z" indicating it is a Zone Detail Designation followed by three groups of numbers, the first is the number of zones, the second is the number of laterals per zone, the third is the runs per lateral.
_______ Z = Zone | _______ # Zones | _______ # Laterals | _______ # Runs/Lat |
| EXAMPLE 1 | |
___Z___ Z = Zone | ___3___ # Zones | ___3___ # Laterals | ___3___ # Runs/Lat |
This example shows a three zone detail with three laterals per zone and three runs per lateral.
ZONE DETAIL SELECTION PROCEDURE
Reference the site plan layout to determine the width across contour of the delineated area. From the site and soils evaluation determine the total amount of tubing required. The area divided by two is the total linear feet of tubing required. The total linear feet of tubing required. The total linear feet of tubing required. The total linear feet of tubing divided by the length across contour equals the minimum number of runs.
The total number of linear feet of tubing and runs will typically be more than the minimum since the preferred layout for flushing the supply and return lines will typically result in more than the minimum tubing. The preferred layout is the next largest zone detail. Increasing the number of runs in order to install a standard zone configuration is encouraged. This provides an additional safety factor to the tubing interface loading rate. Use the following step by step procedure to select a zone detail.

| Effluent Quality |
| 2 |
|
Number of Bedrooms |
| 3 |
|
Design quantity of wastewater to disperse. (120 GPD per bedroom) |
| 4 |
|
Enter the tubing run length. If run length is not on table, use the actual run length. Example: 85 ft. |
| 5 |
|
Length of supply line between hydraulic unit and farthest zone. |
| 6 |
|
Vertical lift from off level in the pump chamber and highest zone elevation. |
| 7 |
| ______ | Area GPD/ft2 per code |
|
Area loading rate required to treat and disperse wastewater. (See Loading Rate Chart) |
| 8 |
| ______ | Area Calculation (ft2) |
|
Total install area needed to disperse wastewater. (line 3 / line 7) |
| 9 |
|
Required total linear feet of tubing to disperse wastewater. (line 8 / 2) |
| 10a |
|
Number of runs (line 9 / line 4) |
| 10b |
|
Round up to next whole number to determine Min. # Runs. (Reference Zone Detail Table) |
| 11 |
|
Using Zone Detail Table, select zone detail from column with next higher Contour Run Length (line 4) and with equal or greater # of Runs (line 10b). |
| 12 |
|
Determine from Lift & Distance Table, cross Supply LF equal to line 5 with the appropriate number of laterals. |
| 13 |
|
Total linear feet of tubing provided to disperse wastewater. (# of zones x laters per zone x runs per lateral x Contour Run Length) |
| 14 |
|
Total linear feet of tubing per zone. (LF Provided / # of zones) |
| 15 |
| Will zone flush? |
| Y | N |
| ( ) | ( ) |
|
If #12 is greater than #6, the system will flush. Reference Lift & Distance Table for pump capacity determined by the length of run to the farthest field and the number of laterals. (For 1" supply and return only) |
