1. The system shall not be installed In wet or frozen soils.
2. Do not park, drive large equipment, or store materials on the dispersal area. No activity should occur on
dispersal area other than the minimum required to install the system.
3. All installation and construction techniques shall conform to state and local codes pertaining to on-site sewage
systems and the permit for the site.
4, The installation shall be in accordance with specifications and procedures as supplied by the Manufacturer of
the equipment.
5. The contractor shall be certified to install this type of system and should hold a pre -construction meeting with
the individuals responsible for the site design and inspections. The meeting should be held prior to the beginning
of the site work to ensure protection of the site conditions and to ensure that the system is installed_
according to design.
6. If site conditions are determined to require the installation of the system to deviate from the design plans, all
work shall stop Immediately and the DesignerandHealth Agent shall be notified. Any ongoing work shall be
the sole responsibility of the contractor.
7. 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
Hill material in Title 5 at 310 CMR 15.255(3) with cover consisting of sand and topsoil meeting the 6" to 12"
depth requirement. The designer may indicate for the tubing to be installed up to 24" below grade.
All drip tubing is to be installed parallel with the contour.
Vegetative cover must be replaced .for installations where it Is removed or buried during installation.
8. All cutting of rigid PVC pipe, flexible PVC and drip tubing of size 1 1h" or smaller shall be accomplished with
pipe cutters approved by Manufacturer.. No sawing of PVC, flexible PVC or drip tubing of size 1 112" or smaller
is allowed. All rigid PVC pipe, flexible PVC and drip tubing in the work area shall have the ends covered with duct
tape after cutting to prevent construction debris from entering the pipe. Prior to ggluing, all joints shall be inspected
for and cleared of any debris. All PVC pipe and fittings In the field shall be SCH 40 All glued joints shall be cleaned and
primed with PVC primer prior to being glued. All force mains shall be tested for leaks prior to being backfilled by
pressurizing the system and observing for leakage.
9. The Hydraulic Unit is to be placed on a bed of 4"- 6" thick of Y4"- 1'fj" gravel for drainage.
If standing groundwater is a problem In the vicinity of the Hydraulic Unit, o screened drain to daylight is -
required.
Cold Climate Construction Standards
"Pere -Rite Drip Dispersal Systems
1. "Top feed" manifolds are to be used to allow for proper manifold drainage. Top feed manifolds are to be
located slightly higher than the drip tubing.
2. All attempts should be made to place the Hydraulic Unit with an open southern exposure for warming purposes.
3. The supply and return lines shall be Installed below the frost line. The vertical sections of pipe that connect to
the supply and return lines shall be insulated SCH 40 PVC pipe. Insulation shall be minimum 1/2" thick foam (or
equivalent). �" Rigid Foam Insulation may be Installed under the Hydraulic Unit to protect the supply and return
lines in extreme conditions. Sufficient ground cover around the hydraulic unit 1s required for insulation. All pipes
entering and leaving the hydraulic unit shall elbow vertically down 90 degrees to a depth below the frost line
prior to extending away from the unit horizontally. Additional insulation inside the hydraulic unit is encouraged.
Insulation to consist of blue board, bagged Styrofoam, peanuts or equivalent. If fiberglass Insulation is used it
must be sealed to prevent It from becoming saturated.
4. Dense vegetative cover is to be established over the supply trench, return trench and drip tubing prior to the first
exposure to freezing temperatures. If vegetation cannot be established, then trenches and tubing are to be covered
with a thick layer (minimum 6") of mulch, straw/hay, etc. until such turf cover is established.
Established vegetation height over the dispersal area should be a minimum 4'-6" throughout winter months.
5. Contractor shall insulate all "air release valves." Insulation to consist of blue board, bagged Styrofoam peanuts, or
equivalent. If fiberglass insulation is used, it must be sealed to prevent it from becoming saturated release valves
shall be placed below the ground surface Inside a valve box but at an elevation above the highest
drip line in that particular zone.
6. All loops connecting drip runs shall be slightly elevated (minimum 1"- 2") so that they drain into the drip tubing
after the pump shuts off. It Is the contractor's responsibility to ensure these loops stay elevated during and after
the loops are backfilled.
7. All conduit entering into the control panel shall be sealed to prevent condensation inside the panel.
