TL;DR
Hydraulic overload is the failure mode in which a septic system receives more wastewater than its tank and soil field can process, flushing solids into the drainfield and saturating the absorption area before it can drain. Causes include guest-heavy weekends, leaking toilet flappers that run thousands of gallons, water softener backwash, and undersized systems on growing households.
What it means
Hydraulic overload is the failure mode in which a septic system receives more wastewater than its tank and soil field can process, flushing solids into the drainfield and saturating the absorption area before it can drain. Causes include guest-heavy weekends, leaking toilet flappers that run thousands of gallons, water softener backwash, and undersized systems on growing households. Symptoms are soggy turf over the field, gurgling fixtures, and backups after laundry days; spreading out water use and fixing leaks often restores function if the field has not biologically clogged.
