· INSTALL NEW ANCHOR SYSTEM FOR THE SEPTIC TANK.

· INSTALL NEW PRESSURE DOSING EFFLUENT MOUND DRAINFIELD

SYSTEM, WITH 4” OF BOARDSTOCK INSULATION OVER CHAMBERS.

§ MOUND SYSTEM CONTAINS:

§ 6 ROWS OF 9 CHAMBERS, FOR A TOTAL OF 54 CHAMBERS AND 611

SQ FT OF TREATMENT AREA (DISTRIBUTION PIPING IS COVERED

WITH INFILTRATOR CHAMBERS, GEOTEXTILE, AND BOARDSTOCK

INSULATION).

· PUMP-OUT, LIME, ABANDON AND CRUSH IN PLACE THE EXISTING

SEPTIC TANK. ABANDON EXISTING DRAINFIELD IN-PLACE, REMOVE

MONITORING PORTS. COMPACT, LEVEL AND LANDSCAPE AREA.

· FINAL LANDSCAPING: COMPACT, LEVEL, GRASS SEED, AND FERTILIZE

AREA. CLEAN UP SITE. ENSURE DRAINAGE DOES NOT POOL UP ALONG

SEPTIC SYSTEM. MOUND OVER SERVICE LINE, SEPTIC TANK, REPS UNIT,

AND DRAINFIELD TO COMPENSATE FOR SETTLEMENT. ENSURE

ABSORPTION FIELD DESIGN CRITERIA

· 4 BEDROOM HOUSE

· DESIGN FLOW RATE: 150 GAL/DAY/BEDROOM

· TOTAL DESIGN FLOW: 600 GAL/DAY

· SOIL TYPE @ 4FT IS: POORLY GRADED GRAVEL W/ SILT - USCS

CLASSIFICATION: GP-GM

· SOIL TYPE @ 8FT IS: SILTY GRAVEL - USCS CLASSIFICATION: GM

· TEST HOLE DEPTH WAS 10.5FT.

· IMPERMEABLE LAYER IS ASSUMED TO BE 10.5FT.

· GROUNDWATER ENCOUNTERED AT 7.5FT.

· A PERCOLATION TEST WAS INCONCLUSIVE DUE TO A 0.04 MIN/IN

PERCOLATION RATE AND THE WATER IN THE TEST HOLE COULD NOT

GET HIGHER THAN 2IN DURING THE TEST.

· THE LOADING RATE FOR GP SOILS IS 150 SQ FT/ BEDROOM.

· DESIGN WILL BE BED-STYLE DRAINFIELD (SOIL ABSORPTION FIELD)

· IT WILL INCLUDE 2FT OF 3” MINUS COARSE-GRADED SEWER ROCK

· THE SYSTEM WILL HAVE 2FT OF COARSE-GRADED FILTER SAND DUE

THE PERCOLATION RATE AND GROUNDWATER AT 7.5FT IN THE TEST

HOLE.

· IT WILL INCLUDE UTILIZING PERFORATED PIPE, CHAMBERS,

GEOTEXTILE FABRIC, AND BOARDSTOCK.

· THE PRESSURE DISTRIBUTION PIPING WILL BE PROTECTED WITH THE

USE OF INFILTRATOR CHAMBERS, THAT WILL PROTECT THE DISCHARGE

PIPING FROM CLOGGING AND PROVIDE VOID SPACE THAT CAN HANDLE

SEVERE PEAK FLOW EVENTS, AND HELPS WITH THE DISTRIBUTION OF

THE WASTEWATER. IT ALSO EXTENDS THE LIFE OF THE DRAINFIELD.

· ELEVATION OF EXISTING GROUND AT TEST HOLE: 91 FT ASL (ABOVE

SEA LEVEL)

· INFILTRATION AREA REQUIRED = 4 BEDROOMS * 150 SQ FT

/BEDROOM/DAY = 600 SQ FT

· CHAMBER AREA PER UNIT IS: 2.83FT X 4FT LONG = 11.32 SQ

FT/CHAMBER

· # OF CHAMBERS REQUIRED IS = 600 SQ FT / 11.32 SQ FT/CHAMBER = 53

CHAMBERS

· USE 54 CHAMBERS WITH 6 ROWS OF 9 CHAMBERS PER ROW (611 SQ FT)

· FINAL LOADING RATE IS: 600 GAL/DAY / 611 SQ FT = 0.98 GAL/DAY/SQ FT

· 0.98 GAL/DAY/SQ FT IS CLOSE TO THE E.J. TYLER RECOMMENDED 0.8

GAL/DAY/SQ FT FOR COARSE MATERIAL FOR BOD5 LOADING GREATER

THAN 30MG/L WASTEWATER STRENGTH. ACTUAL FOOTPRINT OF

SEWER ROCK IS 16.9FT X 36FT (839 SQ FT) OR 0.71 GAL/DAY/SQ FT

WHICH IS BETTER THAN THE RECOMMENDED 0.8 GAL/DAY/SQ FT.

· SEPTIC TANK SIZING: DEC REQUIREMENT FOR 4 BEDROOM HOME IS A

1,250 GAL SEPTIC TANK. UPSIZE AND USE A 1,500 GALLON INSULATED

POLYETHYLENE INFILTRATOR SEPTIC TANK.

· THE PUMP CHAMBER WILL BE A SEPARATE PUMP BASIN, USE LIBERTY

EFFLUENT INSULATED PUMP BASIN, 36” DIAMETER X 11FT LONG.

DESIGN OF PRESSURE DISTRIBUTION LATERALS AND PUMP DESIGN

· USE 2” SDR 11 HDPE PRESSURE SEWER FORCE MAIN, RUN INSIDE

4”X12” INSULATED ARCTIC PIPE, FROM THE LIFT STATION TO THE

HEADER ASSEMBLY OF THE PRESSURE MOUND DRAINFIELD (6 FT).

· TRANSITION TO 1½” SCH 40 PVC FOR HEADER AND DISTRIBUTION

LATERALS (230FT)

· THERE ARE 6 LATERALS OF 9 CHAMBERS, 16.9FT WIDE BY 36FT LONG

(611 SQ FT)

· THERE ARE 54 CHAMBERS (@11.32SQ FT/CHAMBER = 611 SQ FT)

· USE ¼” CLEAN DRILLED HOLES EVERY 24”, POINTED DOWNWARD

(6-O'CLOCK) AND HUNG UNDER THE CHAMBER. THE SYSTEM NEEDS TO

DRAIN AND DRAINBACK TO THE PUMP CHAMBER FOR FREEZE

PROTECTION.

· THERE ARE 2 HOLES PER CHAMBER OR 108 HOLES TOTAL, AND/OR 18

ORIFICES PER LATERAL WITH 6 LATERALS.

· ONE UPWARD FACING ¼” ORIFICE WILL NEED TO DRILLED AT THE END

OF EACH LATERAL, TO ALLOW AIR INTO THE SYSTEM AND THE

LATERALS TO FULLY DRAIN.

· EACH HOLE WILL COVER/PROVIDE: 611 SQ FT / 108 HOLES = 5.66 SQ FT

PER ORIFICE OF APPLICATION

· E. J. TYLER RECOMMENDS ABOUT A MAXIMUM TREATMENT AREA OF 6

SQ FT PER ORIFICE, SO OKAY.

· THEY RECOMMEND A LATERAL DISTAL PRESSURE OF 2.5FT OF HEAD

PRESSURE AT END OF LATERAL (OR ABOUT 1.1PSI)

· PER E.J. TYLER, TABLE A-1 DISCHARGE RATE FOR ORIFICES, ¼” ORIFICE

@ 2.5' DISTAL PRESSURE = 1.17 GPM PER ORIFICE

· IDEAL FLOW RATE TO MAINTAIN PRESSURE AT FAR END OF

DISTRIBUTION SYSTEM = 1.17 GPM * 108 ORIFICES = 126 GPM

· STATIC ELEVATION HEAD = 6 FT

· ASSUMED HEADLOSS = 33 FT

· TOTAL DYNAMIC HEAD = 39 FT

· ACTUAL FLOW RATE OF SEWAGE PUMP SELECTED IS:

§ LIBERTY EFFLUENT PUMP, FL50, ½ HP PUMP. BASED ON PUMP

CURVE AT 39 FT OF HEAD PUMP PRODUCES 40 GPM

§ 40 GPM IS BELOW THE 210.6 GPM NEEDED TO MAINTAIN AN IDEAL

2.5 PSI, AT EACH ORIFICE, SO IDEAL PRESSURE WILL NOT BE

MAINTAINED TO THE FAR END OF THE DRAINFIELD. HOWEVER,

ORIFICES ARE TURNED DOWN, SO DISTRIBUTION LATERALS WILL

STILL DRAIN BY GRAVITY, EVEN UNDER 0 PSI PRESSURE.

§ RESULT WILL BE A LITTLE UNEVEN DISTRIBUTION WITHIN THE

DRAINFIELD, BUT KEEPS THE PUMP SIZE REASONABLE FOR

OPERATIONAL COSTS AND DOSING. IT IS NOT IDEAL, BUT WILL

WORK. POSITIVE PRESSURE WILL STILL BE MAINTAINED.

· 40 GPM / 108 ORIFICES = 0.37 GPM/ORIFICE (MUCH LESS THAN THE

RECOMMENDED 1.17 GPM/ORIFICE, BUT ACCEPTABLE)

DOSING OF DISTRIBUTION SYSTEM

· VOLUME OF PUMPING CHAMBER

§ 36” DIAMETER, SAY FLOATS ARE 4 FT APART

§ PUMP VOLUME IS ((3.14)*(D^2)/4) *(L) *(7.48 GAL/CU FT) =

((3.14)*(3FT^2)/4)*(2FT)*(7.48 GAL/CU FT) = 106 GALLONS.

§ SET PUMP-OFF FLOAT AT 1FT FROM BOTTOM OF TANK, AND

PUMP-ON WILL BE ABOUT 3FT FROM THE BOTTOM OF TANK,

RESULTING IN A PUMP VOLUME OF ABOUT 106 GALLONS

· PUMP RUN TIME = 106 GAL/CYCLE / 40 GAL/MIN = 2.65 MIN/CYCLE

· PUMP CYCLE TIME = 600 GPD / 106 GAL/CYCLE = 5.66 CYCLES PER DAY

(ACCEPTABLE)

· THE REPS PUMP WILL RUN FOR 2.65 MIN/CYCLE * 5.66 CYCLES/DAY =

15.0 MINUTES PER DAY

§ A ½ HP PUMP USES ROUGHLY 1,380 WATTS TO RUN AND WOULD

USE 345 WATT-HOURS PER DAY. EQUIVALENT TO A 65 WATT

LIGHT BULB RUNNING FOR 5.3 HOURS PER DAY.

SITE SPECIFIC DESIGN AND CONSTRUCTION NOTES

· THE SYSTEM MUST DRAINBACK INTO THE PUMP CHAMBER AFTER EACH

PUMP CYCLE, SO THE PRESSURE LINE MUST SLOPE BACK TO THE PUMP

CHAMBER AND A 1/4” WEEP HOLE DRILLED UPSTREAM OF THE CHECK

VALVE, BUT DOWNSTREAM OF BALL VALVE. AN UPWARD FACING

ORIFICE WILL NEED TO BE INSTALLED AT THE END OF THE LATERAL TO

ALLOW AIR INTO THE SYSTEM TO DRAIN.

· AS THIS SYSTEM IS REPS UNIT, AND PRESSURE DISTRIBUTION MOUND

DRAINFIELD, THE START-UP OF THE FACILITY SHALL BE COORDINATED

AND ARRANGED WITH THE PROJECT MANAGER AND ENGINEER.

SUCCESSFUL SYSTEM START-UP, TROUBLESHOOTING, AND

ADDRESSING ANY INSPECTION CONCERNS, MUST ALL BE COMPLETED

BEFORE FINAL CONTRACT PAYMENT.

· THE SEWER SERVICE LINE WILL BE 4” X 12” ARCTIC PIPE WITH 2” OF

BOARDSTOCK INSULATION OVER THE ARCTIC PIPE AND HAVE 4” OF

BOARDSTOCK INSULATION OVER THE SEPTIC TANK, REPS UNIT, AND

DRAINFIELD.

· THE 2” HDPE PRESSURE LINE, FROM THE LIFT STATION TO THE HEADER

PIPING (AND HEADER), WILL BE INSIDE A 4” X 12” INSULATED ARCTIC

CARRIER PIPE AND COVERED WITH 2” OF BOARDSTOCK INSULATION.

· THERE WILL BE A MINIMUM 4FT OF COVER OVER THE SEWER PIPE,

REPS UNIT, SEPTIC TANK, AND DRAINFIELD.

· NEW WINDOW WELL TO BE GALVANIZED STEEL (50" W X 36" D X 36" H).

THE WINDOW WELL WILL ALLOW FOR EASIER ACCESS TO THE ARCTIC

BOX AT EG.

ABSORPTION FIELD DESIGN CRITERIA

· 1 BEDROOM HOUSE; UPSIZE AND USE 2 BEDROOMS FOR FLOW RATE TO

BE MORE CONSERVATIVE

· DESIGN FLOW RATE: 150 GAL/DAY/BEDROOM

· TOTAL DESIGN FLOW: 300 GAL/DAY

· SOIL TYPE @ 4FT IS: WELL GRADED GRAVEL WITH SAND - USCS

CLASSIFICATION: GW

· SOIL TYPE @ 8FT IS: NO SAMPLE COLLECTED AT 8FT DUE TO

PERMAFROST AT 5FT

· TEST HOLE DEPTH WAS 5FT DUE TO PERMAFROST.

· IMPERMEABLE LAYER IS 5FT.

· WATER SEEPS ENCOUNTERED AT 4.5FT.

· A PERCOLATION TEST WAS NOT PERFORMED DUE TO THE

PERMAFROST BEING ENCOUNTERED AT 5FT IN THE TEST HOLE.

· THE LOADING RATE FOR GW SOILS REQUIRES A LOADING RATE IS 150

SQFT/BR ASSUMING A PERCOLATION TEST FASTER THAN 1 MIN/IN TO BE

MORE CONSERVATIVE.

· DESIGN WILL BE BED-STYLE DRAINFIELD (SOIL ABSORPTION FIELD)

· IT WILL INCLUDE 2FT OF 3” MINUS COARSE-GRADED SEWER ROCK.

· THE SYSTEM WILL HAVE 4FT OF COARSE-GRADED FILTER SAND DUE

THE PERMAFROST AT 5FT IN THE TEST HOLE.

· IT WILL INCLUDE UTILIZING PERFORATED PIPE, CHAMBERS,

GEOTEXTILE FABRIC, AND BOARDSTOCK.

· THE PRESSURE DISTRIBUTION PIPING WILL BE PROTECTED WITH THE

USE OF INFILTRATOR CHAMBERS, THAT WILL PROTECT THE DISCHARGE

PIPING FROM CLOGGING AND PROVIDE VOID SPACE THAT CAN HANDLE

SEVERE PEAK FLOW EVENTS, AND HELPS WITH THE DISTRIBUTION OF

THE WASTEWATER. IT ALSO EXTENDS THE LIFE OF THE DRAINFIELD.

· ELEVATION OF EXISTING GROUND AT TEST HOLE: 13 FT ASL (ABOVE

SEA LEVEL)

· INFILTRATION AREA REQUIRED = 2 BEDROOMS * 150 SQ FT

/BEDROOM/DAY = 300 SQ FT

· CHAMBER AREA PER UNIT IS: 2.83FT X 4FT LONG = 11.32 SQ

FT/CHAMBER

· # OF CHAMBERS REQUIRED IS = 300 SQ FT / 11.32 SQ FT/CHAMBER =

26.5 CHAMBERS

· USE 28 CHAMBERS WITH 4 ROWS OF 7 CHAMBERS PER ROW (316 SQ FT)

· FINAL LOADING RATE IS: 300 GAL/DAY / 316 SQ FT = 0.95 GAL/DAY/SQ FT

· 0.95 GAL/DAY/SQ FT IS CLOSE TO THE E.J. TYLER RECOMMENDED 0.8

GAL/DAY/SQ FT FOR COARSE SAND MATERIAL FOR BOD5 LOADING

GREATER THAN 30MG/L WASTEWATER STRENGTH. ACTUAL FOOTPRINT

OF SEWER ROCK IS 15.3FT X 32FT (490 SQ FT) OR 0.61 GAL/DAY/SQ FT

WHICH IS BETTER THAN THE RECOMMENDED 0.8 GAL/DAY/SQ FT.

· SEPTIC TANK SIZING: DEC REQUIREMENT FOR 2 BEDROOM HOME IS A

1,000 GAL SEPTIC TANK. USE A 1,000 GALLON INSULATED

POLYETHYLENE INFILTRATOR SEPTIC TANK.

· THE PUMP CHAMBER WILL BE A SEPARATE PUMP BASIN, USE LIBERTY

EFFLUENT INSULATED PUMP BASIN, 36” DIAMETER X 11FT LONG.

DESIGN OF PRESSURE DISTRIBUTION LATERALS & PUMP DESIGN

· USE 2” SDR 11 HDPE PRESSURE SEWER FORCE MAIN, RUN INSIDE

4”X12” INSULATED ARCTIC PIPE, FROM THE LIFT STATION TO THE

HEADER ASSEMBLY OF THE PRESSURE MOUND DRAINFIELD (21FT).

· TRANSITION TO 1½” SCH 40 PVC FOR HEADER AND DISTRIBUTION

LATERALS (121FT)

· THERE ARE 4 LATERALS OF 7 CHAMBERS, 11.3FT WIDE BY 28FT LONG

(316 SQ FT)

· THERE ARE 28 CHAMBERS (@11.32SQ FT/CHAMBER = 316 SQ FT)

· USE ¼” CLEAN DRILLED HOLES EVERY 24”, POINTED DOWNWARD

(6-O'CLOCK) AND HUNG UNDER THE CHAMBER. THE SYSTEM NEEDS TO

DRAIN AND DRAINBACK TO THE PUMP CHAMBER FOR FREEZE

PROTECTION.

· THERE ARE 2 HOLES PER CHAMBER OR 56 HOLES TOTAL, AND/OR 14

ORIFICES PER LATERAL WITH 4 LATERALS.

· ONE UPWARD FACING ¼” ORIFICE WILL NEED TO DRILLED AT THE END

OF EACH LATERAL, TO ALLOW AIR INTO THE SYSTEM AND THE

LATERALS TO FULLY DRAIN.

· EACH HOLE WILL COVER/PROVIDE: 316 SQ FT / 56 HOLES = 5.66 SQ FT

PER ORIFICE OF APPLICATION

· E. J. TYLER RECOMMENDS ABOUT A MAXIMUM TREATMENT AREA OF 6

SQ FT PER ORIFICE, SO OKAY.

· THEY RECOMMEND A LATERAL DISTAL PRESSURE OF 2.5FT OF HEAD

PRESSURE AT END OF LATERAL (OR ABOUT 1.1PSI)

· PER E.J. TYLER, TABLE A-1 DISCHARGE RATE FOR ORIFICES, ¼” ORIFICE

@ 2.5' DISTAL PRESSURE = 1.17 GPM PER ORIFICE

· IDEAL FLOW RATE TO MAINTAIN PRESSURE AT FAR END OF

DISTRIBUTION SYSTEM = 1.17 GPM * 56 ORIFICES = 65.5 GPM

· STATIC ELEVATION HEAD = 12 FT

· ASSUMED HEADLOSS = 23 FT

· TOTAL DYNAMIC HEAD = 35 FT

· ACTUAL FLOW RATE OF SEWAGE PUMP SELECTED IS:

§ LIBERTY EFFLUENT PUMP, FL50, 1/2 HP PUMP. BASED ON PUMP

CURVE AT 35 FT OF HEAD PUMP PRODUCES 46 GPM

§ 46 GPM IS BELOW THE 65.5 GPM NEEDED TO MAINTAIN AN IDEAL

2.5 PSI, AT EACH ORIFICE, SO IDEAL PRESSURE WILL NOT BE

MAINTAINED TO THE FAR END OF THE DRAINFIELD. HOWEVER,

ORIFICES ARE TURNED DOWN, SO DISTRIBUTION LATERALS WILL

STILL DRAIN BY GRAVITY, EVEN UNDER 0 PSI PRESSURE.

§ RESULT WILL BE A LITTLE UNEVEN DISTRIBUTION WITHIN THE

DRAINFIELD, BUT KEEPS THE PUMP SIZE REASONABLE FOR

OPERATIONAL COSTS AND DOSING. IT IS NOT IDEAL, BUT WILL

WORK. POSITIVE PRESSURE WILL STILL BE MAINTAINED.

· 46 GPM / 56 ORIFICES = 0.82 GPM/ORIFICE (MUCH LESS THAN THE

RECOMMENDED 1.17 GPM/ORIFICE, BUT ACCEPTABLE)

DOSING OF DISTRIBUTION SYSTEM

· VOLUME OF PUMPING CHAMBER

§ 36” DIAMETER, SAY FLOATS ARE 4 FT APART

§ PUMP VOLUME IS ((3.14)*(D^2)/4) *(L) *(7.48 GAL/CU FT) =

((3.14)*(3FT^2)/4)*(1FT)*(7.48 GAL/CU FT) = 53 GALLONS.

§ SET PUMP-OFF FLOAT AT 1FT FROM BOTTOM OF TANK, AND

PUMP-ON WILL BE ABOUT 2FT FROM THE BOTTOM OF TANK,

RESULTING IN A PUMP VOLUME OF ABOUT 53 GALLONS

· PUMP RUN TIME = 53 GAL/CYCLE / 46 GAL/MIN = 1.15 MIN/CYCLE

· PUMP CYCLE TIME = 300 GPD / 53 GAL/CYCLE = 5.66 CYCLES PER DAY

(ACCEPTABLE)

· THE REPS PUMP WILL RUN FOR 1.15 MIN/CYCLE * 5.66 CYCLES/DAY = 6.5

MINUTES PER DAY

§ A 1/2 HP PUMP USES ROUGHLY 1,380 WATTS TO RUN AND WOULD

USE 149.7 WATT-HOURS PER DAY. EQUIVALENT TO A 65 WATT

LIGHT BULB RUNNING FOR 2.5 HOURS PER DAY.

SITE SPECIFIC DESIGN AND CONSTRUCTION NOTES

· THE SYSTEM MUST DRAINBACK INTO THE PUMP CHAMBER AFTER EACH

PUMP CYCLE, SO THE PRESSURE LINE MUST SLOPE BACK TO THE PUMP

CHAMBER AND A 1/4” WEEP HOLE DRILLED UPSTREAM OF THE CHECK

VALVE, BUT DOWNSTREAM OF BALL VALVE. AN UPWARD FACING

ORIFICE WILL NEED TO BE INSTALLED AT THE END OF THE LATERAL TO

ALLOW AIR INTO THE SYSTEM TO DRAIN.

· AS THIS SYSTEM IS REPS UNIT, AND PRESSURE DISTRIBUTION MOUND

DRAINFIELD, THE START-UP OF THE FACILITY SHALL BE COORDINATED

AND ARRANGED WITH THE PROJECT MANAGER AND ENGINEER.

SUCCESSFUL SYSTEM START-UP, TROUBLESHOOTING, AND

ADDRESSING ANY INSPECTION CONCERNS, MUST ALL BE COMPLETED

BEFORE FINAL CONTRACT PAYMENT.

· THE SEWER SERVICE LINE WILL BE 4” X 12” ARCTIC PIPE WITH 2” OF

BOARDSTOCK INSULATION ALL AROUND THE ARCTIC PIPE.

· THE SEPTIC TANK AND REPS UNIT TO HAVE 4” OF BOARDSTOCK

INSULATION ALL AROUND THE SEPTIC TANK AND REPS UNIT, AT THE

BOTTOM THERE WILL BE 12” OF BEDDING FOLLOWED BY 4” OF

BOARDSTOCK INSULATION FOLLOWED BY ANOTHER 12” OF BEDDING.

· THE 2” HDPE PRESSURE LINE, FROM THE LIFT STATION TO THE HEADER

PIPING (AND HEADER), WILL BE INSIDE A 4” X 12” ARCTIC CARRIER PIPE

AND COVERED WITH 2” OF BOARDSTOCK INSULATION.

· THE DRAINFIELD WILL BE COVER WITH 4” OF BOARDSTOCK INSULATION.

· THERE WILL BE A MINIMUM 4FT OF COVER OVER THE ARCTIC SEWER

PIPE, REPS UNIT, SEPTIC TANK, AND DRAINFIELD.
