INTRODUCTION

This Perc-Rite Drip System Designer's Guide is 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. The tables have conditions which allow the designer considerable flexibility to layout systems in a variety of siting conditions without being required to do engineering calculations to determine design suitablity. When advanced system design is required, outside the limitations of this design procedure, the designer must reference the design manual located on ou web site and complete a detailed calculation sheet to determine suitability. Reference our web site at "americanonsite.com".

The Perc-Rite Drip System is a unique fluid handling system for dispersal of effluent wastewater in soil systems. The system incorporates filtration, time and level controlled application and ultra low rate drip distribution. In conditions where aerobic dispersal, such as "Low Pressure Distribution", of septic effluent is required or where land application with the use of conventional soil absorption fields are not acceptable, this system offers a unique method for subsurface distribution of the waste water effluent.

Preconditioning Treatment requirements for Perc-Rite Drip Systems are minimum. The process will accommodate virtually any type of pretreatment process, septic tank (anaerobic), aerobic, lagoon, or any type of treatment facility. Only primary treatment (the removal of large settleable solids) of sewage is necessary for the operation of the system. Local soil and site conditions may require additional treatment for excessive organics, oil and grease or other contaminants.



Virtually No Site Disturbance during installation of the field distribution lines causes very little soil disturbance. The effluent discharge volume from each emitter hole is very small. The installation of the system has very little site impact even in established lawns or park areas. After installation there are virtually no visible indications that the installation site is being used for disposal purposes. This system is especially suited for landscaped or wooded areas near buildings, trailer parks, apartment complexes or residential subdivisions.

TYPICAL LAYOUT



SYSTEM COMPONENTS

  1. 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.


  2. 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.


  3. 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.


  4. 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.


  5. 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.


  6. 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.


  7. 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.


DESIGN PROCEDURES

  1. DEMAND ANALYSIS - Local codes determine the amount of wastewater to design for. Many codes have a safety factor or peak flow factor in the prescribed design flow. Others are based on more of an average usage. In either event, the designer must determine what the peak (design) flow is. The Perc-Rite Drip System will disperse the average flow through out each day unless the "Peak " float is enabled at which time the system will disperse effluent at an accelerated design daily flow rate. Record the peak design flow on line 1 of the worksheet.


  2. SITE AND SOILS EVALUATION - Soil evaluation is required on each site and the procedures used are not included in this manual. however the results of the evaluation are used. The designer must determine from the information provided by the evaluator the "Design loading rate". The design loading rate may be expressed as the "area" or as the linear feet of tubing required. The delineated area for installation and the installation depth needs to be determined. Long and narrow runs along contour are best. Be sure to adhere to applicable State and local codes. The Soil Loading Rate Table provided should be used as a guidence tool only. The professional judgement of the evaluator and designer should determine the wastewater application rate for any specific site. Record the selected loading rate on line 2 of the worksheet. The total linear feet of tubing required is line 1 divided by line 2. Record the total linear feet of tubing required on line 3 of the worksheet.


  3. DELINEATE AREA - On a site plan or a site sketch, the designer should layout the area of installation on contour. The width along contour should be determined and this distance will determined the necessary down slope distance in order to allocate sufficient total area. The distance down slope will dictate the number of runs which can be install in the dispersal site. Make sure enough runs can be installed for the total wastewater capacity and the amount of tubing required. Site conditions determine the run separation. Runs can vary from 1' to 3' separartion but are more frequently from1-1/2' to 2' on center.


  4. SELECT ZONE DETAL - Once the area and number of possible runs is determined, a standard zone detail is selected based on the width accross contour ane the number of runs that are needed and can be installed. See the Zone Detail Table. Determine how wide the system can be based on the delineated area on the plan. Then determine how many linear feet of tubing is needed. Match the number of runs across contour that can be installed. From the table select the zone detail for the site. Record the selected zone detail on line 4. Record the total linear feet provided on line 5. Record the total linear feet per zone provided on line 6. Record the dose gpm and FF gpm provided on line 7. See the Zone Detail Table and Dosing & FF Flow Table.


  5. LAYOUT SITE - On a site plan or site sketch show the route for the supply and return pipes. Show the distance the supply and return pipes travel. On a site plan or site sketch show the layout of the tanks, hydraulic and the control panel. Determine the length of supply line run and record on line 8, determine the lift to the field and record on line 9.


  6. DETERMINE SUITABILITY - Reference the Lift and Run Table to determined by the length of run to the farthest field and the number of laterals, if the layout is suitable for 1" supply and return only. If the selected zone detail is included in the zone table and the lift is inexcess of the required for the length of run in the pump table, record a Yes in line 10 of the worksheet.

AREA DELINIATION

A complete site evaluation includes a surface characterization of topographic features and horizontal setbacks, a subsurface (soil) evaluation, and the accurate delineation of the soil adsorption area. This delineation is best performed by the site evaluator. The area should be marked and measured in the field to insure protection of the area and a representative final adsorption area design. Tools required would include a measuring tape to dimension the site, stakes to delineate the area, and a leveling device such as a builders level, locke level, or clinometer to determine contour.

Care should be exercised to insure accuracy on sites with limited area, and those that are topographically complex to minimize site skewing, account for topographic contour wrapping, and verification of available area. The header ditch(es) area should be as perpendicular to topographic contour as possible.



SOIL LOADING RATE TABLE
This is based on a standard tubing spacing between runs of 2 feet on center. Therefore a typical area loading rate would be a number which is one half the linearfeet loading rate number. For example, for a 1.2 gallons/L.ft./day rate would be equivalent to 0.6 gallons/ft2/day. Spacing may be changed for specific site conditions. For example: a tubing loading rate of 0.4 is an area load of 0.2. By placing the tubing 1' on center, the resulting area loading would be at 0.4, or 1/2 of the area. This can only be done with proper site and soil evaluation.

Site suitability, loading rate, and installation depth determination must be assigned based on thorough site/soil evaluation. The characterization of a soil based receiver site involves a systematic evaluation by trained individuals. Conditions to consider consist of a variety of topographic and soil conditions such as landscape position, slope, soil depth, depth to water table, depth to restriction, soil consistence, clay mineralogy, compaction, density, and site geometry and uniformity.

Drip dipsosal lends itself to shallow installation. Typical depths are from 6-18", with 8-10" preferred and 18-24" installations infrequent. Separation to limitations should always be maximized while maintaining a consistent depth on contour in a permeable horizon.

Refer to state and local regulatory requirements for appropriate site suitability guidance.



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.

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.

  1. Determine width across contour.
  2. Determining number of runs that can be installed in area.
  3. Select a standard zone detail from under the column for contour with which has enough tubing to satisfy total tubing requirements.
  4. In the event more runs are needed to yield enough tubing for the site, the tubing may be placed closer than 2' on center.
EXAMPLE;
Contour width=125 Feet
Tubing required=2400 Linear Feet

From the table the linear feet of tubing provided in 125 foot runs will be between 2250 LF and 2500 LF. Therefore select 20 runs for 2500 LF. The zone detail could be:

___Z___
Z = Zone
___4___
# Zones
___5___
# Laterals

# Runs/Lat

Finally confirm that the number of runs can be installed into the delineated area.

RUN TIME TABLES
The run time tables are based on the gallons per day the system is designed for. The run time numbers are based on the average daily flow rate. Selecting the run time is the last design step that is performed. Based on the number of zones and the number of laterals per zone, the run time is selected based on the average gallons per day. For even distribution and minimizing draindown events, the run time is calculated to provide from 3 to 5 times the vloume of drip tubing plus the top feed manifolds. Therefore, the number of doses per zone will vary in order to maintain optimum dispersal.

INSTALLATION INSTRUCTIONS

  1. Prepare field location for installation. Verify contour and design. No wet weather installation. No activity on drainfield other than minimum to install system. Clearing of vegetation to be performed with minimal site disturbance. Do not park equipment or store materials on drainfield area.


  2. Set pretreatment and pump tanks.


  3. Dig header ditch for field manifold.


  4. Install dripper tubing. Horizontal spacing between dripper lines shall be as specified and installation depth shall be as specified. Install on contour.


  5. Install loops (flex tubing) and construct field supply / return manifolds. All PVC pipe and fittings shal be PVC SCH 40 type 1 rated for pressure applications. All glued joints shall be cleaned and primed with purple (dyed) PVC primer prior to being glued. All cutting of PVC pipe, flexible PVC and/or dripper tubing shall be accomplished with pipe cutters. Sawing of PVC pipe, flexible PVC and/or dripper tubing shall be followed by cleaning all shavings or sawing should not be allowed. All open PVC pipe, flexible PVC and/or dripper tubing in the work area shall have the ends covered with duct tape during construction to prevent construction to prevent construction debris from entering the pipe. Prior to gluing all glue joints shall be inspected for and cleared of construction debris.


  6. Dig ditches for conveyance lines, pump supply line, and flush return line. Install. Connect supply / return lines with manifolds.


  7. Place Central Unit and mount control panel. Connect conveyance, supply, and flush return lines to hydraulic unit.


  8. Set switch tree in pump tank.


  9. Install electrical (and phone line if applicable). Check power supply and power up unit.


  10. Provide one day volume of clean water for startup. Prior to startup of the drip disposal system the air release valves shall be removed and each zone in the system shall be flushed as follows: a) using an appropriate length of flexible PVC pipe with a male fitting attached to the air release connection to direct the flushing away from the construction are, b) flush the zone with a volume of water (clean water to be provided by contractor) equal to 1.5 times the volume of the pipes from the central unit to the air release valve, c) repeat this procedure for each zone (the flushing of the system is accomplished by manual override of the control panel by the manufacturer of engineer.) Once completed replace and glue air relief valves.

    If existing septic tanks are to be used, they shall be pumped out by a commercial septic tank pumper, checked for leakage or other problems, and replaced if necessary. After the tank is emptied, the tank shall be rinsed, pumped, and refilled with clean water. Debris is septic tank shall be kept to a minimum since it could clog the disk filters during startup. (Disk filters are not backflushed during startup and any clogging could cause incorrect rate of flow readings for the controller.)


  11. Pressure check all fittings and lines. Inspect field and loops. Find leaks and repair.


  12. Check setup values against calculated values. Set run time for Central Unit.


  13. Backfill once lines and fields are determined to have no leaks. backfilling is to be controlled to prevent the damaging of pipes or fittings. Once completed, drainfield area should be graded to shed surface water with additional clean soil as necessary. Establish fescue or other turf cover, cut long (6-8").


OPERATION AND MAINTENANCE FOR PERC-RITE® DRIP SYSTEM

The PERC-RITE® DRIP SYSTEM has been developed to automatically monitor operational functions. the system is designed to be easily fixed after it breaks, in other words periodic monitoring can confirm good operating conditions but there are no maintenance procedures necessary until a mechanical component becomes in need of repair. Further, any malfunction or breakage of a mechanical component will result in a failure similar to any traditional system, a wet spot in the field, a backup or a high level alarm.

The MONITORING FREQUENCY should be no more than traditional systems. The most important component for the operational success is owner awareness. All onsite systems have a finite hydraulic capacity. Drip systems have no storage capacity in the soil system so storage or flow equalization must be provided in the pump tank. The owner must be aware system exists and the peak flow limitations for usage.

After a successful installation and startup the system should be inspected from one to three months after the owner takes occupancy to confirm operational compliance and to inform the owner of the operational characteristics of the system. The system should then go on a schedule of annual inspections to monitor usage and inspect system for wear in order to minimize emergency service requirements. Each system is provided with an owners manual. The local dealer has a more detailed installation and maintenance supplement manual. If more than septic pretreatment is provided, more frequent monitoring may be required. Provide monitoring frequency a the rate determined by the most sensitive component.

An OPERATIONAL CHECKLIST is provided in the dealer's supplement manual for determining satisfactory operation of the system. The following topics are covered:

1.  Field Conditions
2.  Check septic tank and pump tank condition
3.  Check operation of pump, control and valves
4.  Check zone dose rates
5.  Evaluate and record meter for usage
