SOURCE: Filed with the Secretary of State December 20, 1977, effective
December 20, 1977; codified at 6 Ill. Reg. 13019, effective October 12,
1982; amended at 21 Ill. Reg. 12439, effective August 28, 1997.
SUBPART A: PERMITS
<BSection 374.101 Introduction>>
These design criteria are to be used by the Illinois Environmental
Protection Agency in reviewing 35 Ill. Adm. Code 309, Subpart B permit
applications for pressure sewer systems including grinder pump systems and
septic tank effluent pumping (STEP) systems.
(Source: Amended at 21 Ill. Reg. 12439, effective August 28, 1997)
<BSection 374.102 Conventional System Preference>>
If possible, the development proposed shall be served by a conventional
sewer system. A conventional sewer system is defined as gravity sewers or
a conventionally designed pumping station.
(Source: Amended at 21 Ill. Reg. 12439, effective August 28, 1997)
<BSection 374.103 System Pressure Maintenance>>
The owner or operator of a pressure sewer system shall provide a method of
inspection or authorization to assure that users of the system maintain the
original design operating pressures of the system when repairing, modifying
or replacing any of the pumping equipment on the user's premises.
(Source: Amended at 21 Ill. Reg. 12439, effective August 28, 1997)
<BSection 374.104 Sludge Disposal>>
Permits for STEP systems shall not be issued unless the applicant provides
satisfactory evidence that adequate facilities are available for the
pumping and disposal of septic tank sludge.
(Source: Section 374.104 repealed and new Section 374.104 renumbered
from Section 374.105 at 21 Ill. Reg.12439, effective August 28,
1997)
<BSection 374.105 Sludge Disposal (Renumbered)>>
(Source: Section 374.105 renumbered to Section 374.104 at 21 Ill.
Reg. 12439, effective August 28, 1997)
<BSection 374.106 Pressure System Failure (Repealed)>>
(Source: Repealed at 21 Ill. Reg. 12439, effective August 28, 1997)
SUBPART B: DESIGN CRITERIA
<BSection 374.201 Duplex Pumps>>
If grinder pumps are serving more than one building, duplex pumping units
shall be required. If the pumps are to be installed for individual
buildings, a single pumping unit may be used.
(Source: Amended at 21 Ill. Reg. 12439, effective August 28, 1997)
<BSection 374.202 Minimum Size>>
The grinder pump "wet well" should have a minimum size of 150 gallons.
<BSection 374.203 Valves>>
Valve arrangements and connection shall be made so as to allow quick
removal and replacement of equipment for maintenance purposes.
<BSection 374.204 Non-corrosive Equipment>>
Non-corrosive or corrosion-resistant equipment shall be specified for STEP
systems.
<BSection 374.205 Influent Pumping>>
In the STEP systems, pump well influent piping should enter at the bottom
of the well to prevent cascading of septic effluent in order to minimize
both odor and corrosion.
<BSection 374.206 Pump Vaults>>
All pump vaults shall be equipped with locking covers.
<BSection 374.207 Marked Sewer Lines>>
Where polyvinyl chloride (PVC) pressure mains are to be installed in the
vicinity of similar water supply lines, the sewer line should be clearly
marked to prevent possible future cross-connections.
(Source: Amended at 21 Ill. Reg. 12439, effective August 28, 1997)
<BSection 374.208 Alarm Systems>>
An alarm system shall be provided in the home where grinder units are
installed in the basement to alert the home owner in case of pump
malfunction. A visual alarm system shall be provided for those pumping
units installed in a separate pumping vault outside of the home.
