Do apartment buildings have septic tanks?

The short answer is, “Yes.”

However, it’s not very common. While several apartment units might share a single large septic tank, they still each need enough lateral lines to treat their effluent. So, a single apartment building would need several acres of leach field. An apartment complex would need to devote over half the land to wastewater treatment.

Advanced wastewater systems are a better option for apartments outside the reach of sanitary sewers. Because they treat septic effluent in a biological reactor rather than in the ground, they can reduce the acreage needed for disposal.

Here’s an example of apartment complex wastewater treatment that works :

Upon entering this apartment complex, you drive past the clubhouse and wind by a lush slope. Spoiler: it’s the wastewater drip field.
