4. Deep Test Hole Information indicates soil condition, percolation
rate, and water table elevation at the time and location of actual
testing and should be verified at the time of construction.
5. The contractor shall notify the local Board of Health ,if GROUNDWATER
or P]KRCIIED WATER is encountered at a higher elevation than .indicated
on this design plan.
6. Notify the local Board of Health when the system is ready, for
INSPECTION, prior to any backfilling.

(17) of Title V and replace with clean coarse sand and gravel, free
from fines, clay, organics, stumps, and waste construction
materials.
15. Unless specified in the Basis of Sanitary Design, this system is
NOT designed for the use of a garbage grinder, hot tub, or other

10. All construction litter and debris is to be removed
from the vicinity of the Haybale line daily.
11. Any substantial silt accumulation
overwashingagainst

A. PUMP TYPE: Myers E-3 1/3 hp. 1/8" solids -handling effluent
pump with 1" NPT discharge. 230v., 7 amp, 1 phase, 60hz.
B. ALARM CONTROL PANEL: EA-1 115v. with 20 amp pump circuit
and separate 15 amp alarm circuit.
C. FLOATS: Pump.... Proximity switch set at elevation shown on
plan
Alarm ... Myers P-M (NO) polypropylene switch with
stainless steel hardware
D. JUNCTION BOX: 100% waterproof polypropylene junction box,
attached to the end of the electrical conduit, is to be
installed directly under the pump chamber access to
facilitate pump, alarm, and float connections.
PUMP CHAMBER:
E. Pump chamber and septic tank seams, riser connections
(if any), and all plumbing joints are to be installed
100% WATERPROOF. Any groundwater or surface water
entering the system will severely limit the life span of
the leaching area.
h. DISTRIBUTION BOX cover is to be built up to finished
grade and is to be equipped with a "tee" on. the inlet
line.
G. A check valve is NOT to be installed in the plump
discharge line unless a 3/16 inch minimum weep hole is
inserted downstream of the check valve.
It. Electrical wiring between the main bldg. and pump
chamber is to be encased in conduit with proper;
fittings at each end to maintain a waterproof
connection.
I. Electrical installation shall conform with the N. E. C.
Code and any applicable local regulations.
J. Alarm system is to incorporate a pump disconnect switch
activated automatically when visual and audible alarm
sounds (Meyers EA-1 or equivalent).
K. PRESSURE LINE: 1-1/4" Schedule 40 Pvc minimum or
equivalent
L. PRESSURE LINE SLOPE: 5 % minimum to ensure all effluent
in pipe will backflow to pump basin when pump switches
off, and to prevent any depressions or pockets in the
pump line path that would continuously hold effluent.
M. In case of pump failure, the pump chamber and septic tank
are to be pumped by a licensed sewage hauler prior to
repairing of sewage pump. This procedure will ensure no
overload of the leaching area will occur when pump in
restarted.
N. A warning sign is to be placed on the pump chamber cover
stating: 1. disconnect power prior to serviciiifr, and 2.
proper ventilation to be used when working oti the pump
to prevent a build up of sewer gases-
0. A backup generator (adequate for slipplyint; the sewage
pump in case of electrical failure) is stone,*ly
recommended.
