“Aerobic treatment unit” means a disposal system employing bacterial action that is maintained by the utilization of air or oxygen and includes the aeration plant and equipment and the method of final effluent disposal.
2.
3.
2.
3.

5.
“Packed bed media filter” means a watertight structure filled with uniformly sized media that is normally placed over an underdrain system.
The wastewater is dosed onto the surface of the media through a distribution network and is allowed to percolate through the media to the underdrain system.
The underdrain collects the filtrate and discharges the final effluent.
6.
“Private sewage disposal system” means a system that provides for the treatment or disposal of domestic sewage from four or fewer dwelling units or the equivalent of less than sixteen individuals on a continuing basis, including domestic waste, whether residential or nonresidential, but not including industrial waste of any flow rate except as provided for in 567 IAC 68.8.

However, a class A system shall be inspected at least annually.
A class A system shall be maintained at least annually.
A class B system shall be inspected at least twice per year or more frequently if required by the manufacturer’s specifications.
A class B system shall be maintained at least twice per year or more frequently if required by the manufacturer’s specifications.

All monitoring and maintenance shall be performed by a certified technician.
All maintenance and visual inspections shall be performed by a certified technician.
A certified technician shall report results to the system owner and to the county sanitarian.
A certified technician shall report results, as provided in section 455B.243, to the system owner and to the applicable administrative authority within thirty days following the inspection.
All inspections shall be performed by the county sanitarian and such results shall be reported as required in section 455B.243.
The certified technician shall also report any discontinuance or proprietary treatment system maintenance to the applicable administrative authority.
For a class A proprietary treatment system, a media filter such as a peat moss biofilter, coconut fiber filter, synthetic foam filter, polystyrene bead media filter, or textile filter may be used if the site is unacceptable for a soil absorption system and an intermittent sand filter.
A proprietary treatment system may be used when the applicable administrative authority determines the site is unacceptable for a conventional subsurface soil absorption system.
Preference should be given to the use of a class A system due to the higher maintenance requirements of aerobic treatment units and fixed film systems.
Preference shall be given to the use of a class A system due to the operating principle being similar to that of intermittent subsurface sand filter beds.
An aerobic treatment unit may be used only when the site is unacceptable for a soil absorption system or an intermittent sand filter.
A class B system shall not be used on a vacation home, church, or event facility, or other seasonal or infrequent use facilities.
Because of the higher maintenance requirements of aerobic treatment units, preference should be given to packed bed media filters where conditions allow.
For a class B proprietary treatment system, an aerobic treatment unit and modular fixed film system may only be used when the site is unacceptable for a soil absorption system, LSB 6893SV (1) 91 -2- sb/js 2/5 S.F.
A class B proprietary treatment system that discharges treated effluent on the surface of the ground shall receive additional treatment through the use of intermittent free access sand filters of a magnitude not exceeding five gallons per square foot of design flow.
2255 intermittent sand filter, and class A system.
A class B system shall not be used for a vacation home, church, event facility, or infrequent-use facility.
6.
An aerobic treatment unit that discharges on the surface of the ground shall have either an intermittently operated slow sand filter or a free access sand filter on the discharge, with both types of sand filters sized at a maximum of five gallons per square foot of design flow.
The free access sand filter shall have a minimum of twenty-four inches of filter sand over the top of a collection system.
The free access sand filter cover shall be easily opened to clean the sand surface.
