• Method: HomeGuide's published per-gallon range applied to your tank size, plus the county fee schedule for any sanitary permit. Lake lots with limited access add local labor.

• Step 1, records: Waukesha County Environmental Health keeps sanitary permit records and maintenance history for each system.
• Step 2, maintenance: Wisconsin Administrative Code SPS 383.55 requires the tank to be inspected or pumped on schedule, typically every three years, and the report filed with the county.
• Step 3, reconstruction: the county's fee schedule lists $252 to replace a septic, pump or holding tank due to structural failure or to add capacity, and $381 to remove a clogging layer in a mound.
• Step 4, replacement systems: a licensed plumber submits the sanitary permit; the fee schedule lists $551 for an in-ground soil absorption system, $1,167 for a mound or at-grade system, $869 for a holding tank and $170 to transfer or renew a permit.

• Kettle Moraine sand and gravel: outwash in western Waukesha County near Dousman and Eagle drains very fast, so separation from groundwater matters more than absorption.
• Lake water table: homes near Okauchee, Pewaukee and Oconomowoc lakes often have a high water table, which is why many lake lots have mounds.
• Clay till: eastern parts of the county near Brookfield and New Berlin have clay till that drains slowly.
• Frost: deep winter frost freezes shallow pipes; schedule pumping before freeze-up.
• USDA NRCS soil survey data for Waukesha County (survey WI133) map 119,699 of 371,530 acres, 32.2%, as poorly drained and 82,747 acres, 22.3%, with a water table within about 12 inches of the surface.
• Older homes: lake cottages built in the 1950s and 1960s and later winterized often have small, older tanks.
