1. THIS PLAN IS FOR THE DESIGN, PERMITTING AND CONSTRUCTION OF A SUBSURFACE SEWAGE DISPOSAL SYSTEM ONLY.
PLEASE NOTE THAT THIS SYSTEM IS NOT DESIGNED FOR THE USE OF A GARBAGE GRINDER NOR DOES DECELLE-BURKE &
ASSOCIATES RECOMMEND THE USE OF A GARBAGE GRINDER WITH A SEPTIC SYSTEM DUE TO THEIR RECOGNIZED ADVERSE
IMPACTS TO THE SUBSURFACE ADSORPTION SYSTEM.
2. ALL CONSTRUCTION METHODS AND MATERIALS TO CONFORM THE MASSACHUSETTS D.E.P. TITLE 5 REGULATIONS AND
LOCAL BOARD OF HEALTH REGULATIONS. ALL PIPING TO BE SCHEDULE 40 PVC UNLESS OTHERWISE SPECIFIED.
3. WITHIN LIMIT OF EXCAVATION, REMOVE ALL IMPERVIOUS MATERIAL INCLUDING THE 'A" & 'B' SOIL HORIZONS.
4. FILL MATERIAL REQUIRED TO REPLACE TOPSOIL, SUBSOIL OR ANY UNSUITABLE MATERIAL SHALL COMPLY WITH SECTION
310 CMR 15.255. INSTALLER IS RESPONSIBLE FOR HAVING A SIEVE ANALYSIS PERFORMED ON THE FILL MATERIAL AND
PROVIDING A COPY OF THE RESULTS TO THIS OFFICE THE SOIL SHALL CONFORM TO THE FOLLOWING SIEVE ANALYSIS:
10% (MAX) BY WT. SHALL PASS No. 50 SIEVE
<10% OF No. 4 SIEVE SHALL PASS No. 100 SIEVE
<5% OF No. 4 SIEVE SHALL PASS No. 200 SIEVE
UNIFORMITY COEFFICIENT ® No. 4 SIEVE </= 6.0.
5. SEPTIC TANK SHALL BE CONSTRUCTED OF REINFORCED CONCRETE WITH AT LEAST THREE (3) WATER TIGHT ACCESS
MANHOLES, TWO OF WHICH ARE WITHIN 6' OF FINISHED GRADE SEPTIC TANK SHALL BE SET LEVEL ON A 6' STONE BASE.
6. DISTRIBUTION BOX SHALL BE CONSTRUCTED OF REINFORCED CONCRETE WITH A WATER TIGHT COVER. THE DISTRIBUTION
BOX SHALL BE SET LEVEL ON A 6' STONE BASE
7. CAST IRON FRAMES AND COVERS SHAT. BE PROVIDED OVER ALL SEPTIC SYSTEM COMPONENTS WHEN LOCATED WITHIN A
TRAFFIC AREA.
8. THE DESIGN IS INTENDED TO MEET TIRE V AND ANY LOCAL REGULATIONS. THIS IS NOT A GUARANTEE THAT THE SYSTEM
WILL BE INSTALLED AS DESIGNED NOR DOES THIS PLAN GUARANTEE THE OPERATION OF THE SYSTEM.
9. TOPOGRAPHY SHOWN HEREON IS THE RESULT OF AN ON THE GROUND SURVEY BY DECELLE-BURKE & ASSOCIATES IN
MAY 2012. THE DATUM IS NGVD29 AND A BENCHMARK IS LOCATED ON THE CONCRETE BOUND LOCATED NORTHWEST
CORNER OF THE LOT. SEE PLAN.
11. UTILITIES SHOWN ARE APPROXIMATE. THE CONTRACTOR SHALL BE RESPONSIBLE FOR PROPERLY LOCATING AND
COORDINATING THE PROPOSED CONSTRUCTION ACTIVITY WITH DIG -SAFE, THE LAND OWNER AND THE UTILITY PURVEYORS.
DIG -SAFE SHALL BE NOTIFIED 72 HOURS PRIOR TO ANY CONSTRUCTION ACTIVITY ON THE SITE AT 1-888-344-7233.
THE ENGINEER DOES NOT GUARANTEE THBR ACCURACY OR THAT ALL UTILITIES AND SUBSURFACE STRUCTURES ARE SHOWN.
THE CONTRACTOR IS RESPONSIBLE TO VERIFY LOCATIONS OF Al UTILITIES THAT MAY CROSS THE CONSTRUCTION ACTIVITY
AND VERIFY LOCATIONS OF UTILITY CONNECTIONS INCLUDE) IN THE CONSTRUCTION PRIOR TO ANY UTILITY CONSTRUCTION.
