This is illustrates a Greywater System, which is designed to reuse wastewater from showers and baths for purposes like garden irrigation.
Here’s a breakdown of how the system works:
---
1. Shower
The process starts with water being used in a shower or bath.
This used water is called greywater — relatively clean wastewater that does not contain human waste (unlike blackwater from toilets).
---
2. Collection and Filtration Tank
The greywater flows from the shower drain into a filtration tank.
Inside this tank, there are three layers of filtration:
Coarse Filter: Removes large particles like hair and soap scum.
Sand Filter: Further cleans the water by removing smaller particles and organic matter.
Metal Filter: Provides fine filtration to remove very small contaminants.
---
3. Pump System
A pump moves the filtered greywater out of the tank.
The system can direct the water through two outlets:
To Sewer: If the system is full or not in use, excess water is sent to the sewer.
To Garden: A hose delivers the filtered water directly to garden plants, conserving clean water and supporting sustainable irrigation.

Benefits of the System
Water conservation: Reuses water that would otherwise go to waste.
Eco-friendly: Reduces demand on municipal water supplies and sewage treatment.
Cost savings: Lowers water bills, especially in dry or drought-prone areas.

Important Note:
Greywater systems must be properly designed and maintained to avoid contamination or unpleasant odors. It is not suitable for drinking or cooking use.
