How do bunkers handle waste management?
Waste management is critical in a sealed bunker, because improper handling can lead to disease, odors, and system failures. Here’s how it’s typically handled:
- Portable Toilets
- Small or short-term bunkers often use chemical or bucket-style toilets.
- Waste is stored in sealed containers and removed or treated outside the bunker.
- Composting Toilets
- Biological toilets turn human waste into compost with minimal water.
- Useful for long-term bunkers, reducing the need for storage or removal.
- Require ventilation to manage odors and airflow.
- Septic or Holding Tanks
- Larger bunkers may have underground holding tanks or septic systems.
- Tanks store waste, which is pumped out or treated periodically.
- Can handle multiple users for weeks or months depending on size.
- Greywater Recycling
- Wastewater from sinks, showers, and laundry (greywater) can be filtered and reused for flushing toilets or irrigation.
- Helps conserve water and extend supplies in long-term scenarios.
