I. Purpose
l. The purpose of this Certification is to allow the use of the System in
Massachusetts on a General Use basis.
2. With the necessary permits and approvals required by 310 CMR 15.000, this
Certi�cation authorizes the use of the System in Massachusetts.
3. The System may be installed on all facilities where a system in compliance with
310 CMR 15.000 exists on site or could be built and for which a site evaluation in
compliance with 310 CMR 15.000 has been approved by the local approving
authority; or by DEP if DEP approval is required by 310 CMR 15.000. The
System is used for disposal of wastewater from a Title 5 septic tank designed in
accordance with 310 CMR 15.223 to 310 CMR 15.229.
4. The System is approved for use at facilities with a design flow less than 10,000
gallons per day (GPD).
II. Design Standards
1. The System is a pressure distributed subsurface wastewater drip dispersal (disposal)
system that replaces a soil absorption system(SAS) designed in accordance with 310
CMR 15.000. The System is designed to distribute septic tank effluent and pressure
discharge it at a depth of at least 6 inches below finished grade. The System includes a
pump chamber, a filter module/hydraulic unit and drip dispersal zone(s) with drip tubing
incorporating discharge emitters. The dispersal zone(s) include small diameter flexible
polyethylene tubing with pressure compensating emitters. The emitters are located at
two foot spacing within the tubing. They operate on a pressure differential across the
emitter, with wastewater discharged in small doses. Dispersal field dosing is timed and
controlled electronically to provide pre-programmed volumes of effluent for discharge to
� each dispersal zone(s). The System includes two-stage (the ASD models) automatic
backwashing disc filters within the filter module. The system allows periodic
, backwashing of the filtration system and forward-flushing of the dispersal tubing with
the dirty effluent conveyed by return line to the septic tank. All drip tubing and shallow
manifolds shall be designed to drain into the soil upon completion of the pump cycle.
The Systern includes two-stage automatic backwashing disc filters within the filter
module and air vents in each dispersal zone. Each zone shall have air release valves at
the high points of manifolds and check valves on each return rnanifold.
2. The System may be installed in the A,B or C soil horizon at a depth of at least 6 inches
below the finished grade, or in fill material meeting the specifications at 310 CMR
15.255(3).
3. All access ports and manhole covers shall be installed and maintained at grade to allow
for maintenance of the System.
4. The control panel including alarms and controls shall be mounted in a location always
accessible to the System operator. System unit malfunction and high water alarms shall

each be connected to an independent power source from the operating pump(s) run from
the main power source of the facility
' 5. The System may be installed in soils with a percolation rate of up to 60 minutes per inch
(MPI). The System shall not be installed in Class N soils as defined in 310 CMR
15.243.
6. No System shall be designed and constructed with less than 4001inear feet of drip tubing
or a soil absorption system area of less than 800 square feet
7. The S stem is e uivalent to a ressure distribution s stem desi ned in accordance with
Y 9 P Y g
the Department's Pressure Distribution Guidance.
8. The System does not require a five foot over dig as indicated at 310 CMR 15.255(5).
9. System control units, valve boxes, drip dispersal lines, conveyance lines and other
System appurtenances shall be designed and installed to prevent freezing per Company
recommendations.
10. The System design, installation and operation including design loading rates shall be in
accordance with the Department's, Guidance for Desi�n, Installation and Operation of
Subsurface Drip Distribution Svsterns as a Renlacement for Conventional Title 5 Soil
Absorption Systems for Disposal of Septic Tank Effluent, dated October 27, 2006 as
revised below:
a. Drip tubing may be installed with a vibratory plow, a static plow, a narrow
trencher (<6"width), by hand trenching, or by scarifying the surface and
bedding the drip tubing in clean sand meeting the requirements for fill
material in Title 5 at 310 CMR 15.255(3) with cover consisting of sand and
topsoil meeting the 6 to 12 inch depth requirement. Vegetative cover must be
` replaced for installations where it is rernoved or buried during installation.
. b. The drip tubing may be installed at 24 inch spacing.
c. When the reserve area is proposed between primary drip lines, the primary
drip lines must be spaced a minimum of 24 inches apart.
11. Effluent tee filters shall be a requirement for septic tanks.
12. Dosing chambers and pumps shall be designed in accordance with 310 CMR 15.231.
Timed dosing with multiple small doses of the drip tubing shall be required for these
systems. The dosing chamber between the septic tank and the drip dispersal system, shall
be sized and equipped so as to permit timed dosing of the daily sewage flow and shall
have a 24 hour reserve storage capacity for system malfunctions.
13. The System shall be equipped with a control panel to regulate dosing frequency/volume,
record the number doses, field flushing events and other pertinent information.
