Signs Your Drainfield Is Failing

The yard usually tells you before the plumbing does.

A failing drainfield rarely announces itself with a single dramatic event. It shows up as a pattern of smaller things, mostly outside, that add up.

Unusually green or lush grass over the field

Effluent surfacing near the surface acts like free water and fertilizer, and it is especially visible in a dry Utah summer when the rest of the lawn is stressed and one stripe of grass stays green anyway.

Standing water or soggy ground

Especially without recent rain or irrigation nearby, and especially concentrated over the footprint of the field rather than spread evenly across the yard.

Sewage odor outdoors

More noticeable near the tank or field area, and often stronger in still air or after a spike in water use in the house.

Slow drains throughout the house, not just one fixture

A single slow drain is usually a local clog. Multiple slow drains and gurgling across several fixtures point toward the tank or field, not the plumbing itself.

Backups in the lowest drain first

A basement floor drain or the lowest fixture in the house backs up before anything upstairs does, simply because it is the lowest point the system can push back into.

Timing tied to heavy water use

Problems that show up after laundry day or when guests are staying over suggest the field is at its absorption limit under peak load, which is not automatically the same as a field that has failed outright.

What to do first

Do not assume the field is gone. A pump-out and inspection determines whether tank solids are carrying over into a field that is otherwise fine, or whether the soil itself has stopped accepting effluent.
