Workshop Module 3: Houses, Water, and Waste Management 103The benefits of wastewater gardens include:
- They don’t cost very much to make and require minimal maintenance.
- The outflow from the system is an effective fertilizer.
- They are sealed so no wastewater contaminates the soil, ground water, or
coastal waters. - They reduce the amount of pollutants from wastewater and make the water safe
for irrigation. - They remove the potential for stagnant wastewater around houses, which is a
breeding area for mosquitoes and water born bacteria.
The facilitator can show images, which explain different types of wastewater treatment
systems and explain in more detail a basic system for home use that can be replicated
at low cost using local resources in villages.
