[Amended 7-27-2016 by Ord. No. 16-16]
The Public Works Director or other duly authorized person of
the utility authorized to issue permits shall require any sewer builder
or contractors seeking a permit from the utility which will include
therein the breaking or entering through the surface of subsurface
of any street in the Village to produce a permit from the Village
for the breaking or entering the surface or subsurface of such street
before any permit will issue from the utility.
[Amended 7-27-2016 by Ord. No. 16-16]
A. From and after the passage, approval, and publication of this chapter,
no sanitary sewer which is designed and is to be constructed so as
to constitute an integral part of the system of sanitary sewers within
the boundaries of this utility as such boundaries are now defined
and limited to be controlled, operated, and maintained by the Village
shall be constructed unless the Public Works Director has been furnished
with three complete sets of plans and specifications, prepared with
competent engineering assistance. The utility shall approve or disapprove
such plans and specifications. The Public Works Director or his or
her authorized agent shall determine whether the additional permit
or permits will not overload the reserve capacity which will not allow
the utility system to adequately handle the additional anticipated
load.
B. No person or persons shall construct or cause to be constructed any
sewer or appurtenance which is to become a part of the sewer system
of this utility except under a written permit for the work issued
by the utility and approved by the Public Works Director upon the
payment of applicable fee to the utility as set from time to time
by the Village Board.
[Amended 4-14-1997 by Ord. No. 97-18]
Basement drainage (excluding footing tiles) shall be discharged
into the sanitary sewer if served otherwise into the septic tank system.
In flat areas where a subsurface the system is to be used, an ejection
pump is recommended for lifting basement drainage into the sanitary
sewer if served otherwise into the septic tank.
Sink drains should be equipped with grease traps of a capacity
of at least 2/3 gallon per capita, and shall discharge to the sanitary
sewer if served otherwise into the septic tank.
[Amended 7-27-2016 by Ord. No. 16-16]
In the event that a soil seepage test is required:
A. Dig a hole one foot square to the depth of the proposed tile field
trenches, in the vicinity of the proposed tile field. If groundwater
is encountered, conditions are unfavorable for a seepage system.
B. Fill the test hole with water to ensure thorough moistening of the
soil and allow the water to seep away. While the bottom of the hole
is still moist, again fill with water to a depth of six inches, and
record the time required for the water to fall six inches and report
the average time per inch of fall.
C. A report of the time of the test set forth in Subsection
B shall be made in writing to the Village Board of Health or the Grundy County Health Department.
Septic tank effluents shall be treated and disposed of in accordance
with one of the types of disposal systems described below. The type
of system to be used shall be determined by the Village Board of Health
of the Grundy County Health Department, and shall be based largely
upon the results of one or more soil seepage tests.
A. Type A: subsurface tile field.
(1) If the time of the soil seepage test is satisfactory (within three
hours for six inches of water), a subsurface tile system will be recommended
for septic tank effluent. The sewer from the septic tank to the laterals
of the disposal field shall be constructed of vitrified bell- and
spigot-tile with cemented joints.
(2) The subsurface tile field shall present a minimum of 600 square feet
of absorption area, calculated as trench width times trench length.
The trenches for the tile lines shall be no more than 75 feet long,
no less than 18 inches wide, and provide a top cover over the tile
of no more than 36 inches. A cover of 18 inches is preferred. There
shall be a minimum of two tile lines per field. The tile lines shall
consist of field tile no less than four inches in diameter laid on
a downslope of two inches to four inches per 100 feet with 1/4 inch
to 1/2 inch open joints, the top of which shall be covered with tar
paper. The tiles shall be surrounded by at least six inches of coarse
gravel, or equivalent, below and two inches above tile. The lines
shall either have blind ends or shall be looped completely. There
shall be a minimum of 10 feet between individual lines and a minimum
of 10 feet between lines and property lines. Distribution boxes with
baffles shall be used in any case deemed necessary by this department.
B. Type B: open sand filter. If soil seepage tests indicate the soil
is unsuitable (over three hours for six inches of water) for subsurface
tile disposal systems, the use of an open sand filter may be permitted
if recommended by the Village Board of Health or the Grundy County
Health Department after a study of the individual case, if the design
is approved in writing by either body. For open sand filter systems
involving more than 15 persons, a permit from the state Environmental
Protection Agency is also necessary.
C. Type C: seepage pit (not recommended). Seepage pits or cesspools
are the least effective and least desirable of all types of tank effluent
disposal and shall not be used except where other methods are shown
to be impractical, and the Village Board of Health or the Grundy County
Health Department approves their use.
Septic tanks should be inspected yearly. In general, a depth
of floating scum of about one foot at the inlet would indicate that
cleaning is necessary. Sludge shall not be placed on vegetable gardens.
It may be plowed under for use as fertilizer, or shall be buried.
Lots shall be of sufficient size to accommodate the installations
without danger to the water supply. The dimension shall not be smaller
than those specified in the Zoning Code.
Installations serving more than 15 persons need approval of
the state Environmental Protection Agency in Springfield, Illinois.
State law prohibits additional pollution of watercourses. For this
reason, no installation will be approved which empties untreated or
partially treated sewage into a watercourse or into a so-called "sewer"
which in turn discharges into the watercourse.
