25B-4 of the 'Sonoma County code to Permit Shallow Sealing of Agricultural
Wells."
The Board of Supervisors -of the County of Sonoma, State of California, do
ordain as follows:
Sec. 25B-4. Construction requirements.
(a) Requirements for Well Construction - All materials and workmanship
shall be no.less than the: quality specified herein. The requirements of these
standards are minimal dnly,and 'any material or method determined by the
`Administrative Authority to give equivalent, or better results, may be
permitted. Materials or methods not covered by these standards must receive
the written approval of the Administrative Authority prior to use. Wells
intended as a water supply source for a'Public Hater System. as defined in
Article Z of this chapter shall be constructed in accordance with the
standards recommended by the California Department of -Water Resources - Bull.
No.. 74 - Water Well Standards: State of California.
(b) Location - Wells shall be located as prescribed in Table 1..
Table I.
Minimum Distances
From Property Line 5 feet
11
From -Septic Tank -Sewage Disposal System 100 feet
From Pub11c or Private Sewer Pipe Line of 25 feet
approved watertight piping and joining materials
From Other Public or Private Sewer Pipe Line 50 feet
From Subsurface' Disposal Field 100 feet
From Seepage Pit 150 feet
(c) Exemption A well may be %nstalled closer than the min'i'mum distances
prescribed in Table I if the Administrative AuLhur'ity finds that compliance is
impractical because of unusual cond'i-tions and if he finds that special
standards may be applied to the well construction so that i,n his opinion no
danger of contamination or 'pollution to the potable ground water will result,
however, under no; circumstances shall a well be constructed less than 50 feet
from a septic tank or sewage di-spoal system. Such special "standards of
construction shall be approved by the'Admimistrative Authority and additional
inspections may be required to assure strict conformance with such special,
standards. Such a well., test well, test hole or observation well >shall
require a Class II permit.
(d) Protection - At all times :during the progress .of the work the well
shall be protected in such a manner as to .preuen.t, as far as possible,
tampering with the well, the entrance of foreign matter into the well or the
entrance of drilling mud into streams, etc. Water and drilling mud used in
drilling shall be free from contamination, *or rendered Free from contamination
by chlorination or other approved methods. Pits constructed for recirculation
of drilling mud during construction shall be so protected that no undue safety
hazard is created for man or animals..
(.e.) Casings:' - All metal casing used in well construction shall be new and
shall have a minimum thickness of 12 ga'ug-e for wells up to and including 8
inches in d-ame.,ter, and a minimum thickness of 10 gauge for wells .10 .inches in
diameter or over.
A1l..casings shall be placedwith suf.fiaienl :care to avoid damage to casing
sections or joints.. The uppermost perforation shall be at least 25 feet below
the ground sudfsce; except in the case of a shallow well and below an
impervious stratum whenever possible.
All concrete pipe casing used in well_ construction shall be. new, free of
defects and shall conform to the latest rey.isi,o.n of the following'
specifications (AWWA C301).
(1) State of.California Specifications for concrete culvert pipe (ASTM
C-14) plain concrete pipe or equal.
(2) State of California Specifications for reinforced concrete culvert;
reinforced concrete pipe specs. (ASTM C- 76 and/or ASSHO M-170) or equal.
All polyvinychloride-casing used in -well construction shall be new, free
of defects, and shall be class 160 or equivalent, and shall mee;t.ASTM 2241-73
and 1784-69 standards..
Other casing material may be accepted upon recommendation -of the -Well"'
Standards Advisory and Appeals Board..
The casing shall extend at least 6 'i"nc'hes above the ground surface, and at
least one-half (1/2) inch above the surface of any surrounding concrete slab.
Exceptions may be allowed by the Administrative Authority.
(f) Grouting - The annular space shall be filled with acceptable grout
having a minimum thicknes of two (2) inches, except in the case of a concrete
pipe eased well, which shall be three (3) incrhes.
The grouting material shall consist of neat cement; cement grout, paddled
clay, or concrete.
The grout shall e'xten-d from the ground surface to at least 20 feet below
t'he ground surface, except in the case of shallow wells where no water bearing
stratum is encountered below 20 feet, the grout shall extend to a depth of 10
feet.
Prior to grouting, a packer of cement, concrete, or steel may be installed
at the bottom of the annular space to be grouted. The grout shall be applied
in one continuous process either by pressure or b.yrawity in accordance with
proper construction practice, in such a manner as to exclude surace and other
undesirable water from the well.
(g) Conductor'Casing - When a conductor casing is used, the. grout seal
shall extend at least four. (4) feet below the lowest point of such conductor
casing, or' a minimum of 20 feet.
(h) Gravel - The gravel used shall be clean, selectedand free of
contaminants. In such formations where appreciable amounts of sand or silt
may be drawn from the well.., a pipe for the addition of additional gravel to
the pack may be installed and capped.
(i) Well Pits -'Well p-ts or below ground discharge pipes may be
permitted at the discretion of the Admi.ni.strati:ve Authority. Where the well
casing terminates in a pit below the ground surface., 'the. pit shall be _
constructed of monoli`thi'c, reinforced Class A concrete, or equal, watertight
in all respects. -The top. of such pit shall' be covered either with a concrete
slab or equal material, or wi"th a housing of sati,sf_ac.tory construction. The
casing shall be carri,ed"at least eight (8) inches above the pit floor. The
well pit shall be so constructed and protected that flood, rain., or surface
waters cannot -enter the pit. The pit shall be provided with a drainage sump
and as automatic sump -,pump. (or if topography permits, a "free"' discharge
protected.aga ns.t entrance of rodents, insects -or flooding).. The discharge
p1pe.from 'the sump pump shall not be connected to any sewer'. or pipe drain.
Pits shall have, easy access for proper opera -lion, maintenance and inspection
of the equi;pmen',t and shall have a locked hatch. Doorways or hatches 'shall at
all times' effectli,vely 'keep water out of the pit.
Access, 'Op.enisng-Into Well Casing - Access openings into the well
casing or conductor pipe for addition of gravel to a gravel packed well, for
sounding the well, for air release, for disinfection and for any other purpose
riecetieary for maintenance and operation of the well are permitted, but must
a
terminate: above flood. and 'high water levels, or have a watertight seal. The
openings shall be ,protected by caps against entry of small animals, insects,
flood water, drainage or pump drippage, and other contamination mat -ter.
(k) Disinfection Newly constructed' or reconstructedwells shall be
adequately treated in such a manner as to, disinfect all parts of the well upon
completion with chlorine 'or an equal disinfecting chemical.
(1) Comple:tion - Upon complet-,ion of a well, the driller shall be
responsi:ble.for the abandonment of the pi.t used for circulation of drilling
mud and the installation of a well rover-. Final approval of the water well by
the Administrative Authority requires submission to the Administrative
Authority within 30 worki;ng days of completion of the we11., a completed water
well driller's report made out in detail on the State Department of Water
Resources reporting form or..equal.
(m) Exemption Agricultural well-s are exempt`from.the grouting
requirements as defined in Section 25`B-4(F) of' this or,d-i°nance. Agricultural
wells are defined as wells used to supply water for crop or vineyard
irrigation or other agricultural purposes and not for human consumption or
other domestic uses, and which arelocated in shallow river and stream
underflow areas. Exemptions 'are subject to the submittal of adequate
justification by .the applicant, 'consisting, of but not necessarily limited to:
1.. Well log data. indicating' that a deeper seal. would adversely affect the
production of .the well in supplying the quantity of water required `during the
time of year :of anticipated agricultural use, and,
2. that the reduction in sealing depth would have no adverse effect on
the quality of wate'r.in adjacent wells, or on the underground aquifer.
An agricultural well shall, be sealed to no less than 5 feet.
