GENERAL ABSORPTION AREA NOTES
1. INSTALL CHAMBER UNITS IN ACCORDANCE WITH
MANUFACTURER'S RECOMMENDATIONS.
2. ABSORPTION TRENCHES SHALL BE 3' WIDE OR LESS
AND PARALLEL THE GROUND SURFACE CONTOURS.
PARALLELING TRENCHES SHALL BE SEPARATED BY
A DISTANCE OF 6' MIN.
3. THE BOTTOM OF THE ABSORPTION TRENCHES
SHALL BE LEVEL AND THE BOTTOM AND
SIDEWALLS MUST BE RAKED TO REMOVE ANY SOIL
SMEARS INCURRED DURING THE EXCAVATION.
FAILURE TO DO SO MAY REQUIRE THE CONTRACTOR
TO REPLACE THE ABSORPTION FIELD AT HIS/HER
OWN EXPENSE.
4. DRAINAGE SWALES ARE TO BE PROVIDED ABOVE
AND AROUND THE FIELD, AS NECESSARY, TO
PREVENT SURFACE RUNOFF FROM ENTERING
ABSORPTION AREA.

5. NO EXCAVATION OF THE ABSORPTION FIELD IS TO
BE DONE DURING WET WEATHER AND USE OF
RUBBER TIRE VEHICLES OVER THE ABSORPTION
AREA IS STRICTLY PROHIBITED.
6. UNSUITABLE MATERIAL EXISTING WITHIN THE FIELD
SHALL BE EXCAVATED AND BACKFILL SHALL
CONSIST OF IMPORTED LOAMY SAND OR SANDY
GRAVEL. THE ENGINEER SHALL BE CONTACTED IF
BEDROCK OR GROUNDWATER IS ENCOUNTERED IN
THE OVER -EXCAVATION.

MAINTENANCE NOTES
1. TO ENCOURAGE THE HEALTH AND LONGEVITY OF THE OWTS SYSTEM, THE OWNER SHALL CONSIDER THE FOLLOWING:
MINIMIZE THE AMOUNT OF WATER THAT GOES DOWN THE DRAIN, THE BETTER YOUR SYSTEM WILL WORK.
MINIMIZE SOLIDS GOING DOWN THE DRAIN.
ELIMINATE GARBAGE DISPOSALS OR KEEP THE USE OF GARBAGE DISPOSALS TO A MINIMUM,
MINIMIZE GREASE AND OILS THAT GO DOWN THE DRAIN.
USE LINT FILTERS ON LAUNDRY MACHINE DRAINS.
KEEP SAND AND DIRT OUT OF THE BUILDING DRAIN.
AVOID FLUSHING SANITARY NAPKINS OR PAPER PRODUCTS OTHER THAN TOILET PAPER.
DO NOT USE LYE -BASED DRAIN UNCLOGGER CHEMICALS SUCH AS DRAINO, OVEN -OFF, OR OTHER STRONG
CLEANING AGENTS.
DO NOT PUT ANY "ROOT DETERRENTS" DOWN THE DRAIN.
DO NOT POUR PAINT THINNER, PESTICIDES, PAINTS OR PHOTO LAB CHEMICALS DOWN THE DRAIN
MINIMIZE USE OF CHLORINE BLEACH AND TOILET ADDITIVES.
2. THE OWNER SHALL CONTRACT WITH A SEPTIC TANK INSPECTOR TO INSPECT THE TANK ANNUALLY FOR GREASE AND
SEDIMENT ACCUMULATION. THE INSPECTOR SHALL REMOVED AND PROPERLY DISPOSED OF ACCUMULATED GREASE
AND SEDIMENT AS NEEDED TO ENSURE PROPER FUNCTION OF THE SYSTEM.

SYSTEM NOTES
1. ALL CONSTRUCTION SHALL BE IN ACCORDANCE WITH CDPHE REGULATION 43 ONSITE WASTEWATER TREATMENT SYSTEM (OVVIS) REGULATION, MOST CURRENT
EDITION AND LOCAL AGENCY REQUIREMENTS WHICH MAY OR MAY NOT SPECIFICALLY BE NOTED ON THE DRAWINGS. THE CONTRACTOR SHALL BE RESPONSIBLE
FOR KNOWING AND CONFORMING TO SUCH SPECIFIC DETAILS AS ARE REFERRED TO IN THE ABOVE MENTIONED REGULATIONS. THIS DRAWING DOES NOT
CONSTITUTE AN OWTS PERMIT. A PERMIT MUST BE OBTAINED FROM APPROPRIATE LOCAL AGENCY. THE ENGINEER MUST OBSERVE THE CONSTRUCTED SYSTEM
BEFORE BACKFILL AND PROVIDE A LETTER OF INSPECTION AS REQUIRED BY THE LOCAL AGENCY. A REQUEST FOR INSPECTION MUST BE MADE BY THE
CONTRACTOR AT LEAST 48-HOURS PRIOR TO THE EXPECTED TIME OF BACKFILUNG.
2. DEMAND CALCULATIONS (SEC.43.6.A.2.h)
2.A. FOUR (4) BEDROOM RESIDENCE USING TREATMENT LEVEL 1 (111).
2.B. AVERAGE DAILY WASTEWATER FLOW (ADWF) AND ORGANIC LOAD RATE (BOD5):
2.8.2. ADWF = 75 gpd * (3 BEDROOMS " 2 PERSONS/BEDROOM + 1 BEDROOM 1 PERSON) =525 gpd
2.B.3. BOD5 = 0.20 lbs/day " (3 BEDROOMS * 2 PERSONS/BEDROOM + 1 BEDROOM * 1 PERSON) = 1.40 Ibs/day
3.A. INSTALL A 1,250-GALLON TWO (2)-COMPARTMENT TANK (PER TABLE 9-1),
3.B. THE TANK IS NOT SUBJECT TO BUOYANCY.
4. ABSORPTION AREA CALCULATIONS
4.A. GROUNDWATER WAS NOT ENCOUNTERED, THE PROPERTY CONTAINS SLOPES BETWEEN 5-20%, BUT THE SOILS CONTAIN AND LARGE QUANTITY OF
BOULDERS. THEREFORE, THE SYSTEM SHALL BE A SHALLOW GRAVELLESS CHAMBER SYSTEM IN A PARALLEL TRENCH CONFIGURATION.
4.B. SOILS WERE ANALYZED BY KUMAR & ASSOCIATES, INC GEOTECHNICAL ENGINEERS (JUNE 19, 2020; PROJECT NO.20-7-359). THE SOILS ENCOUNTERED
BELOW ABOUT 1 TO 2 FEET OF TOPSOIL, CONSIST OF MEDIUM DENSE TO DENSE SILTY SANDY GRAVEL (1YPE-2A) TO THE MAXIMUM EXCAVATED DEPTH OF
6 FEET, WITH A TREATMENT LEVEL 1 LONG TERM ACCEPTANCE RATE (LTAR) OF 0.50 gpd/SF.
4.C. MINIMUM SOIL TREATMENT AREA, A:
A = ADWF = 525 = 1050 S.F.
4.E. GRAVELLESS CHAMBER SYSTEM:
4.E.1. INFILTRATOR QUICK4: 735 SF / 12 SF/UNIT = 62 UNITS IN TRENCH CONFIGURATION.
4.E.2. ADS ARC 36: 735 SF / 15 SF/UNIT = 49 UNITS IN A TRENCH CONFIGURATION.
5. THIS SYSTEM IS SIZED FOR TYPICAL DOMESTIC WASTES ONLY. BACKWASH OR FLUSHING FLOWS FOR REVERSE OSMOSIS UNITS OR WATER SOFTENERS AND/OR
FILTERS SHOULD NOT BE INTRODUCED INTO THIS SYSTEM.
6. CLEAN OUTS ARE REQUIRED AT THE HOUSE AND AT ALL BENDS AND AT LEAST EVERY 100-FEET BETWEEN THE HOUSE AND THE SEPTIC TANK.
7. THE CONTRACTOR SHALL BE RESPONSIBLE FOR INSTALLING ALL WATER TIGHT COMPONENTS THROUGHOUT THE SYSTEM TO PREVENT INFILTRATION.
8. INSTALL RISERS AS NECESSARY TO BRING ALL ACCESS PORTS TO FINAL GRADE. PORTS SHALL BE MARKED IF CAPS ARE TO BE BURIED.
9. INSTALL 3-INCHES OF BLUEBOARD INSULATION, 3-FEET WIDE, OVER SEWER AND EFFLUENT PIPE WHEREVER DEPTH IS LESS THAN 5-FEET. UNDER NO
CIRCUMSTANCES SHALL COVER BE LESS THAN 2-FEET.
10 SITE PLAN INFORMATION FROM OTHERS. LOCATIONS OF ALL COMPONENTS MAY BE VARIED AS NECESSARY AS LONG AS ALL MINIMUM DISTANCES AND SLOPES
MEET THOSE REQUIRED.
