Waste & Sanitation

Handle human and household waste safely

What you do with waste determines whether you're off-grid or just camping badly. Human waste, greywater and rubbish all need safe, legal handling — and done well, they become resources: compost, soil fertility and less landfill. It's the least glamorous skill and one of the most important.

What you need to know

The concepts that underpin everything else in this skill.

  • The difference between blackwater (toilet), greywater (washing) and solid waste.
  • Composting toilet vs septic system vs holding tank — and their maintenance.
  • Why human waste must be handled differently from animal manure (pathogens).
  • Greywater rules: what can and cannot go on the garden, and where it's legal.
  • Composting as waste management: browns/greens, temperature, turning.
  • Local regulations on on-site wastewater (they vary enormously by region).

What you need to learn

A staged progression — master each level before moving on.

Beginner

  • 01 Run a clean, odour-free composting toilet.
  • 02 Build and maintain a hot compost pile.
  • 03 Separate and reduce household rubbish (what you don't buy, you don't dump).
  • 04 Understand your local wastewater rules.

Intermediate

  • 01 Design a greywater system (branched drain or mulch basin).
  • 02 Manage a septic system and know its maintenance schedule.
  • 03 Compost at scale, including food scraps and garden waste.
  • 04 Build a simple off-grid laundry-to-landscape system.

Advanced

  • 01 Design a full on-site wastewater system to local code.
  • 02 Produce safe, finished compost from humanure (time + temperature).
  • 03 Close the loop: waste → fertility → food production.
  • 04 Handle larger livestock manure systems.

Your next steps

A practical, ordered path from where you are now.

  1. 1 Learn your local wastewater and greywater regulations first.
  2. 2 Decide toilet strategy: composting vs septic vs holding tank.
  3. 3 Start a compost system today — it's cheap and immediately useful.
  4. 4 Audit your household waste and cut what you bring in.
  5. 5 Design greywater use around approved, low-risk methods.
