Identify the installed system from records
Start with paperwork, not guesses. Elkhart County septic information includes a septic lookup request. Permit drawings or service records can help identify existing components before a service visit.
A tank size, a drawing showing a mound or chamber field, or a note about an aerator or pump can point to your system type.
Experimental technology requires an operating permit and maintenance contract for the life of the system; operating permits run for three years and renew with an in-effect service contract and fee. That requirement does not apply to every conventional household.
County process covers soil evaluation, minimum requirements, a drawing or application, and a permit before covered component installation. Repair and replacement procedures differ from new construction. Confirm project-specific scope with ECHD.
Compare common system concepts
These are national examples from EPA materials, not a list of locally approved options for any specific lot. Jurisdiction and site conditions determine what can be permitted.
| System concept | Basic idea | Maintenance question |
|---|---|---|
| Conventional tank and drainfield | Solids settle in the tank; liquid effluent moves to a drainfield for soil treatment. | How often should the tank be pumped, and is the drainfield protected from traffic and excess water? |
| Chamber system | Gravel-less chambers in the drainfield create open space for effluent distribution and soil contact. | Ask which accessible components and drainfield surface conditions the inspection covers. |
| Mound system | A raised sand treatment area receives dosed effluent from a pump chamber. | Check pump, alarm and dosing controls; protect the mound area. |
| Pump/pressure distribution | A feature, not a system type: a pump moves effluent to a drainfield, mound or other treatment area. | Check pump, alarm, floats and controls; tank pumping is separate. |
| Aerobic treatment unit | Tank adds oxygen and may include additional treatment steps before dispersal; it relies on mechanical components. | Service and test air pump, controls and any disinfection component; confirm replacement parts. |
Why the site changes the options
Soil, slope, space and water conditions affect which system can treat wastewater acceptably on a property. A lot with shallow soil, a high seasonal water table, or too little room may need a different approach from a lot with deep, well-drained soils and open space.
Those conditions cannot be assumed across a city, township or county. Elkhart County's published process begins with soil evaluation and minimum requirements before a drawing or application and permit.
A design approved for one parcel does not transfer to another. For an existing system, confirm what is installed and what the county requires for the proposed scope. For a new build, county process and an installation professional guide evaluation and design.
