NOTES
I Contours from field sur-vey by Harris & Clark- Inc
The sanitary system is designed for a proposed four (4) bedroom house The
percolation tests yielded a rate of 1 0 - 10 0 minutes per inch. This requires 675 sf of
effective leaching area
The proposed septic system is as follows
3"N
- 75' rows of 4' wide x I ' deep stone trench at 'i 0 sf/If (221 -5 If x 3 0 = 675 sf)
Total Area Provided = 675 sf
A 100'/o reserve area i,, provided
N
I The septic system is to be constructed according to the Connecticut Public Health
Code Regulations and Technical Standards for Subsurface Sewage Disposal Systems
4 All connecting, pipe after septic tank to be SDR -35
5 MLSS = HF x FF x PF = 20 x 2.0 x I _2 48 ft
6 There are no wells within 75' of the septic system
7 A permit from the 1'ricas Health Department is required prior to construction of the
system
8 There shall be no Cuts within 50' of the downhill side of the system or within 25' of
the sides of the system There shall be no stumps or boulders buried within 50' of the
downhill side of the system
9 Should anv significant variations from test hole data shown (ledge, water, mottling,
soil type) be discovered by the contractor, the engineer shall be notified prior to con-
struction of the system
10 All existing utilities are approximately only It is the contractor's responsibility to
verify "CALL BEFORE YOU DIG" shall be,
erl v all locations prior to construction
notified prior to any construction ( 1-800-922-4455)
I I The proposed spec fill should be a clean bank -run gravel and should contain no more
than 5% fines The fill shall achieve a percolation rate equivalent to the original
In
system design Prior to placement of fill., the fill shall be approved by either the Town
Sanitarian or the Design Engineer The fill shall be placed in 12" lifts and compacted
to 90-95of optimum density Periodic inspections by either the Town Sanitarian or
Design Engineer will be required as the filling progresses
12, All topsoil in the immediate area and within a 5 ft radius of the proposed primary
2
system area shall be removed prior to placement of fill Upon removal of the topsoil
the existing subsoil shall be scarified prior to placement of the fill
