GENERAL NOTES:
1. THIS PLAN IS FOR DESIGN AND
CONSTRUCTION OF THE SEWAGE
DISPOSAL FACILITY ONLY.
2. ALL CONSTRUCTION METHODS AND
MATERIALS SHALL CONFORM TO MASS.
D.E.P TITLE 5 AND LOCAL BOARD
OF HEALTH REGULATIONS.
3. ALL PIPES LOCATED UNDER PAVEMENT
OR TRAVELED WAY SHALL BE SCHEDULE
40 OR EQUAL.
4. THERE ARE NO KNOWN PRIVATE WELLS
LOCATED WITHIN 150 FT. OF THE
PROPOSED LEACHING FACILITY NOR
ANY KNOWN WELLS PROPOSED WITHIN
150' OF ANY KNOWN LEACHING FACILITY.
5. WITHIN LIMIT OF EXCAVATION REMOVE
ALL TOPSOIL, SUBSOIL AND OTHER
IMPERVIOUS MATERIAL-
ATERIAL6.
6.REPLACE ALL EXCAVATED MATERIAL WITH
CLEAN GRANULAR SAND, FREE FROM ORGANIC
MATERIAL AND DELETERIOUS SUBSTANCES.
MIXTURES AND LAYERS OF DIFFERENT CLASSES
OF SOIL SHALL NOT BE USED. THE FILL SHALL
NOT CONTAIN ANY MATERIAL LARGER THAN
TWO INCHES. A SIEVE ANALYSIS, USING A #4
SIEVE, SHALL BE PERFORMED ON A
REPRESENTATIVE SAMPLE OF FILL UP TO 45%
BY WEIGHT OF THE FILL SAMPLE MAY BE
RETAINED ON THE #4 SIEVE. SIEVE ANALYSES
ALSO SHALL BE PERFORMED ON THE FRACTION
OF FILL SAMPLE PASSING THE #4 SIEVE, SUCH
ANALYSES MUST DEMONSTRATE THAT THE
MATERIAL MEETS EACH OF THE FOLLOWING
SPECIFICATIONS:
100% MUST PASS #4 SIEVE
(4.75 mm EFFECTIVE PARTICLE SIZE)
10%-100% MUST PASS #50 SIEVE
(0.30 mm EFFECTIVE PARTICLE SIZE)
09-20% MUST PASS #100 SIEVE
(0.15 mm EFFECTIVE PARTICLE SIZE)
0%-5% MUST PASS #200 SIEVE
(0.075 mm EFFECTIVE PARTICLE SIZE)
7. EXISTING UTILITIES WHERE SHOWN
IN THE DRAWINGS ARE APPROXIMATE.
THE CONTRACTOR SHALL BE RESPON-
SIBLE FOR PROPERLY LOCATING AND
COORDINATING THE PROPOSED CON-
STRUCTION ACTIVITY WITH DIG -SAFE
AND THE APPLICABLE UTILITY
COMPANY AND MAINTAINING THE
EXISTING UTILITY SYSTEM IN SERVICE.
DIG -SAFE SHALL BE NOTIFIED PER
THE STATE OF MASSACHUSETTS
STATUTE CHAPTER 82, SECTION 409
AT TEL, 1-888-344-7233. THE
ENGINEER DOES NOT GUARANTEE
THEIR ACCURACY OR THAT ALL
UTILITIES AND SUBSURFACE STRUCTURES
ARE SHOWN. LOCATIONS AND
ELEVATIONS OF UNDERGROUND UTILITIES
TAKEN FROM RECORD PLANS. THE
CONTRACTOR SHALL VERIFY SIZE,
LOCATION AND INVERTS OF UTILITIES
AND STRUCTURES AS REQUIRED PRIOR
TO THE START OF CONSTRUCTION.
B. THIS SYSTEM IS NOT DESIGNED FOR
THE USE OF A GARBAGE GRINDER.
A GARBAGE GRINDER IS NOT
RECOMMENDED DUE TO RECOGNIZED
ADVERSE IMPACTS TO THE LEACHING
FACILITY.
9. EXITING INVERTS ARE TO BE CHECKED BY
THE CONTRACTOR PRIOR TO CONSTRUCTION.
CONFIRM LOCATION & NUMBER OF INVERTS.
0. THE ENGINEER IS TO BE NOTIFIED OF
ANY FIELD CHANGES THAT MAY BE
REQUIRED.
