Plumbing Septic Percolation Area Calculator
Use actual percolation rate only through explicit independently justified caller rate/loading curve, then budget area; distinct from direct soil-loading area tool, no default correlation or permit.
Description
A percolation result only maps to loading through a justified local calibration.
A percolation result only maps to loading through a justified local calibration. Interpolation must stay within that supplied curve.1
The returned values include Caller interpolated soil loading liters m2 day, Caller percolation derived area m2. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Septic Percolation Area Calculator
Use Plumbing Septic Percolation Area Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No extrapolation, default soil correlation or permit determination is supplied.
Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
How to use Plumbing Septic Percolation Area Calculator and understand its results
- Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
- Enter observedPercolationMinutesPerCm, callerVerifiedRateKnotsMinutesCm, callerVerifiedLoadingKnotsLitersM2Day, callerWastewaterLitersDay using the field table and calculation rules, then run the tool.
- Read callerInterpolatedSoilLoadingLitersM2Day, callerPercolationDerivedAreaM2. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedPercolationMinutesPerCm | Observed percolation minutes per cm | number | Required |
| callerVerifiedRateKnotsMinutesCm | Caller verified rate knots minutes cm | list of number | Required |
| callerVerifiedLoadingKnotsLitersM2Day | Caller verified loading knots liters m2 day | list of number | Required |
| callerWastewaterLitersDay | Caller wastewater liters day | number | Required |
Enter positive observed minutes/cm, aligned calibration lists with at least two strictly increasing finite rate knots and positive loading values, and nonnegative wastewater L/day. Query within the inclusive knot range; return interpolated loading and required area.
loading=linearInterpolation(rateKnots,loadingKnots,observedRate); area=wastewater/loading Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerInterpolatedSoilLoadingLitersM2Day | Caller interpolated soil loading liters m2 day | number |
| callerPercolationDerivedAreaM2 | Caller percolation derived area m2 | number |

}Limitations and assumptions
No extrapolation, default soil correlation or permit determination is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Plumbing Percolation Rate Calculator: A timed percolation observation measures minutes per unit water-level drop. Pooled exposure differs from averaging individual rates. For a complementary task, use Plumbing Septic Drain Field Area Calculator: A drain-field area budget divides design wastewater by verified soil loading. An extra replacement reserve increases total land area.
