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 dispersal lends itself to shallow installation. Typical depths are from 6-18". 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.

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.

Increasing the number of runs in order to install a standard zone configuration is encouraged. This provides additional safety to the tubing interface loading rate. use the following step by step procedure to select a zone detail.

1. Determine width across contour.
2. Determine 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 (under certain conditions).

From the table the linear feet of tubing provided in 100 foot runs will be between 600 LF and 800 LF. Therefore select 8 runs for 800 LF. The zone detail could be:

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

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:
