1. CONTRACTOR IS RESPONSIBLE FOR LOCATING EXISTING UNDERGROUND UTILITIES IN AREAS OF WORK PRIOR
TO ANY WORK. PROVIDE ADEQUATE MEANS OF SUPPORT AND PROTECTION IF UTILITIES ARE TO REMAIN IN PLACE.
2. REMOVE TREES, GRASSES, SHRUBS AND OTHER VEGETATION, IMPROVEMENTS OR OBSTRUCTIONS INTERFERING WITH
INSTALLATION OF NEW CONSTRUCTION UNLESS NOTED OTHERWISE.
3. NEW WASTEWATER SYSTEM DESIGN PARAMETERS:
ACTIVE SYSTEMS
DESIGN FLOW: 600 GPD
WASTEWATER SYSTEM: GRAVITY BED SYSTEM
DESIGN FLOW: 5 BEDROOMS ® 120 GALLONS PER DAY (GPD) PER BEDROOM = 600 GPD
600 (GPD) / 1.2 (LTAR) = 500 SF.
500 x 1.50 (Bed System) = 750 sq. ft.
750 / 3 (Trench Width) = 250 L.F.
6 LINES, 42 LINEAR FEET LONG, 3 FOOT ON CENTER
INNOVATIVE WASTEWATER SYSTEM NO.: NO: IWWS 2015-03—R2
DESIGN FLOW: 5 BEDROOMS 0 120 GALLONS PER DAY (GPD) PER BEDROOM = 600 GPD
600 (GPD) / 1.2 (LTAR) = 500 SF.
500 x 0.60 (REDUCTION) = 300 sq. ft.
300 / 3 (Trench Width) = 100 L.F.
3 LINES, 34 LINEAR FEET LONG, 3 FOOT ON CENTER
TANK CALCULATIONS:
SEPTIC TANK: 600 gpd (DESIGN) x 1.17 + 500ga1 = 1,202 gal
UTILIZE 1,261 gal SEPTIC TANK
Green Acres (STB-459 or EQUAL)
INSTALL ZABEL FILTERS
4. UNLESS OTHERWISE INDICATED ON THE PLAN, CONSTRUCTION OF SEWAGE COLLECTION, TREATMENT AND DISPOSAL SYSTEM IS TO
CONFORM WITH SECTION .1900 "LAWS AND RULES FOR SEWAGE TREATMENT AND DISPOSAL SYSTEMS" OF NORTH
CAROLINA ADMINISTRATIVE CODE, DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES, DIVISION OF ENVIRONMENTAL
HEALTH, ON —SITE WASTEWATER SECTION (15 NCAC 18A.1900).
5. CONSTRUCTION OF SEWAGE COLLECTION SYSTEM, TREATMENT AND DISPOSAL SYSTEM IS TO CONFORM WITH ANY CONDITIONS IMPOSED

7. FILL MATERIAL SHALL HAVE SUCH SOIL TEXTURE TO BE CLASSIFIED AS SAND OR LOAMY SAND (SOIL GROUP 1) UP TO THE TOP OF
THE NITRIFICATION TRENCHES. THE FINAL SIX INCHES OF FILL USED TO COVER THE SYSTEM SHALL HAVE A FINER TEXTURE
(SUCH AS GROUP 11, 111) FOR THE ESTABLISHMENT OF A VEGETATIVE COVER.
THE FILL MATERIAL AND THE EXISTING SOIL SHALL BE MIXED TO A DEPTH OF SIX INCHES BELOW THE INTERFACE. HEAVY
VEGETATIVE COVER OR ORGANIC LITTER SHALL BE REMOVED BEFORE THE FILL MATERIAL IS INCORPORATED.
8. WELL POINTS AND PUMPS SHALL BE SUFFICIENT IN SIZE AND SPACING TO DRAW DOWN WATER TABLE TWO TO THREE FEET BELOW
REQUIRED EXCAVATION FOR SEPTIC AND PUMP TANKS.
9. GRADES SHALL BE ESTABLISHED TO DIVERT RUNOFF AWAY FROM TANKAGE. FINAL GROUND ELEVATION ABOVE TANK SHALL BE AS
INDICATED ON THE DETAIL SHEETS.
10. ALL SURFACE RUNOFF SHALL BE DIVERTED AROUND AND AWAY FROM THE DRAINFIELD AREA. FINISH GRADE SHALL BE LANDSCAPED
TO PREVENT PONDING OF SURFACE WATER. VEGETATE DRAINFIELD AREA AS SPECIFIED IN LANDSCAPE PLAN (BY OTHERS).
11. COMPLETE DESIGN OF REPAIR AREA SYSTEM IS NECESSARY TO OBTAIN A REPAIR PERMIT IN THE EVENT THE REPAIR AREA IS
TO BE ACTIVATED.
12. ALL CLEAN FILL MATERIAL SHALL BE EXCAVATED FROM A LAWFULLY PERMITTED SITE AND ALL EXCAVATED MATERIAL SHALL BE
