About this file

Written by GovTribe AI · Aug 26, 2025

This is a construction plan set for scattered wastewater and water infrastructure improvements in Nome, Alaska, prepared by the Alaska Native Tribal Health Consortium's Division of Environmental Health and Engineering for the Jessica Blanford property. The project involves installing a new residential water and sewer system including a 1,500-gallon steel septic tank with lift station, pressure mound drainfield system with 64 infiltrator chambers, arctic water well with drainback or circulation system, insulated arctic pipe systems, and associated electrical controls. The comprehensive 37-sheet plan set includes detailed drawings for septic system schematics, arctic pipe fittings, well details, pressure systems, electrical components, and construction specifications for cold-climate installations requiring freeze protection measures.

The project addresses the challenging arctic construction environment with specialized components including 4-inch insulated arctic pipe carriers, heat trace systems, pressure tank details with drainback capabilities, and arctic service boxes designed for permafrost conditions. The plans specify extensive insulation requirements, including 4-inch rigid boardstock insulation over all septic system components and specialized arctic well caps and sleeves. Construction must comply with Alaska Department of Environmental Conservation regulations and incorporate anchoring systems for high groundwater conditions, with all installations requiring minimum 4-foot cover depths and specialized cold-weather materials and techniques throughout the system.

FOR A FINAL INFILTRATION RATE OF 750 GAL/DAY / 1,078 SF = 0.70

GAL/DAY/SQ FT. (AN ACCEPTABLE LOADING RATE)

· SEPTIC TANK SIZING: DEC REQUIREMENT FOR 5 BEDROOM HOME IS A

1,500 GAL SEPTIC TANK. USE A 1,500 GALLON INSULATED EPOXY COATED

STEEL SEPTIC TANK FROM ANCHORAGE TANK

· THE SEPTIC TANK WILL NEED TO BE ANCHORED IN THE GROUNDWATER.

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

EFFLUENT PUMP BASIN, 36” DIAMETER X 11FT LONG. (DUE TO HIGH

GROUNDWATER)

DESIGN OF PRESSURE DISTRIBUTION LATERALS AND PUMP DESIGN

· USE 2”, SDR 11, HDPE PRESSURE SEWER FORCE MAIN, RUN INSIDE A 4” X

12” ARCTIC PIPE CARRIER PIPE, FROM THE LIFT STATION TO THE HEADER

ASSEMBLY OF THE PRESSURE MOUND DRAINFIELD (12FT).

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

LATERALS (300FT)

· THERE ARE 16 LATERALS OF 4 CHAMBERS

· THERE ARE 64 CHAMBERS (@11.32SQ FT/CHAMBER = 724 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 128 HOLES TOTAL, AND/OR 8

ORIFICES PER LATERAL WITH 16 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: 724 SQ FT / 128 HOLES = 5.7 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 * 128 ORIFICES = 150 GPM

· STATIC ELEVATION HEAD = 10 FT

· ASSUMED HEADLOSS = 43 FT (300FT @ 14.3FT PER 100FT OF 1.5" SCH 40

PVC PIPE)

· TOTAL DYNAMIC HEAD = 53 FT

· ACTUAL FLOW RATE OF SEWAGE PUMP SELECTED IS:

· LIBERTY EFFLUENT PUMP, FL75, ¾ HP PUMP. BASED ON PUMP CURVE AT

53 FT OF HEAD PUMP PRODUCES 43 GPM

· 43 GPM IS BELOW THE 150 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.

· 43 GPM / 128 ORIFICES = 0.34 GPM/ORIFICE (LESS THAN THE

RECOMMENDED 1.17 GPM/ORIFICE, BUT ACCEPTABLE)

DOSING OF DISTRIBUTION SYSTEM

· VOLUME OF PUMPING CHAMBER (LIBERTY PUMP BASIN)

· 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)*(4FT)*(7.48 GAL/CU FT) = 211 GALLONS.

· SET PUMP-OFF FLOAT AT 1FT FROM BOTTOM OF TANK, AND PUMP-ON WILL

BE ABOUT 5FT FROM THE BOTTOM OF TANK, RESULTING IN A PUMP

VOLUME OF ABOUT 211 GALLONS

· PUMP RUN TIME = 211 GAL/CYCLE / 43 GAL/MIN = 4.9 MIN/CYCLE

· PUMP CYCLE TIME = 750 GPD / 211 GAL/CYCLE = 3.6 CYCLES PER DAY

(ACCEPTABLE)

· THE REPS PUMP WILL RUN FOR 4.9 MIN/CYCLE * 3.6 CYCLES/DAY = 17.6

MINUTES PER DAY

SITE SPECIFIC DESIGN AND CONSTRUCTION NOTES

SEWER

· INSTALL 3 IMMERSION HEATERS, 2 IN THE SEPTIC TANK AND 1 IN THE LIFT

STATION. MIRACO, 110V, 500 WATT STOCK CERAMIC COATED STOCK TANK

HEATER, OR APPROVED EQUAL.

· HEAT TRACE WILL BE RUN ON THE SEWER LINE, FROM THE ARCTIC BOX,

TO THE SEPTIC TANK, AND PAST THE SEPTIC TANK AND LIFT STATION, TO

THE FORCE MAIN GOING TO THE MOUND DRAINFIELD.

· 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 THE BALL VALVE. AN UPWARD FACING

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

DRAINFIELD TO ALLOW AIR INTO THE SYSTEM TO DRAIN.

· AS THIS SYSTEM IS A REPS UNIT WITH PRESSURE DISTRIBUTION

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 FROM THE HOUSE TO THE SEPTIC TANK WILL

BE 4” x 12” ARCTIC PIPE.

· THE SEPTIC TANK AND REPS UNIT WILL NEED TO BE INSULATED AND

COVERED WITH 4” OF INSULATION

· THE 2” HDPE PRESSURE LINE WILL BE RUN INSIDE A 4”X12” ARCTIC PIPE

CARRIER PIPE.

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

TANK, REPS UNIT, AND DRAINFIELD.

WATER

· THIS WELL IS CONSIDERED AN ARCTIC WELL AND WILL REQUIRE AN

INSULATED SLEEVE AROUND THE TOP 10FT OF WELL CASING AND

INCLUDE A FABRICATED ARCTIC CAP.

· THE 1” WATER SERVICE LINE WILL BE RUN INSIDE A 4” X 12” ARCTIC PIPE

CARRIER, WILL HAVE A MINIMUM OF 4' OF SOIL COVER.

· HEAT TRACE, INSIDE 1” PEX CARRIER PIPE, SHOULD EXTEND ALONG THE

WATER SERVICE LINE, INSIDE THE ARCTIC PIPE CARRIER, AND RUN UP

BETWEEN THE OUTSIDE OF THE CASING AND ARCTIC SLEEVE FOR EASE

OF REPLACEMENT. IT TRANSITIONS AT A JUNCTION BOX AT THE WELL

HEAD AND THEN ALSO RUNS BACK DOWN THE INSIDE OF THE CASING,

PAST THE PITLESS ADAPTER, DOWN BELOW WHERE THE PUMP IS SET,

WHEN IN PERMAFROST.

· THE PITLESS ADAPTER SHOULD BE INSTALLED A MINIMUM OF 8' BELOW

EXISTING GRADE TO PREVENT FREEZING ISSUES.

· A STANDARD ARCTIC WELL IS A DRAIN-BACK SYSTEM, BUT IF

PERMAFROST IS ENCOUNTERED, THEN A CIRCULATION SYSTEM IS

REQUIRED.

· IF THE SYSTEM IS A CIRCULATION SYSTEM, THEN THERE WILL BE TWO, 1”

WATERLINES INSIDE THE 4” X 12” CARRIER PIPE, ALONG WITH THE 1” HEAT

TRACE CARRIER PIPE. THIS REQUIRES A DOUBLE PITLESS ADAPTER. THE

RETURN OF THE DROP PIPE WILL OCCUR BELOW THE PERMAFROST

LAYER.
