Why use Grey Water?

Reusing grey water can save up to 11 trillion gallons / 11 tera litres of water per year in the United States alone.

​

Grey water reuse is more widely implementable and effective than most other water conservation solutions currently available, including rainwater harvesting as grey water reuse can be done even in drought situations. 

​

Water is an undeniably integral part of our everyday lives. We use it for drinking, cooking, bathing, washing our clothes and maintaining our lawns and gardens. However, after using it for domestic purposes, we send this water down the drain which need not be the case.

 

Grey water can be reused on site for non-potable uses such as toilet flushing and for irrigating our yards and gardens. 

​

This reduces a household’s water bill as well as the home’s need for freshwater. It has many broader community benefits including: 

  • Reduced freshwater use 

  • Reducing demands on public water supply.

  • Reducing the amount of wastewater entering sewers or on-site treatment systems and less strain on septic systems and municipal treatment plants

  • Reducing pollutants in rivers and streams when grey water enters them - plants thrive on used water with compost from its nutrients

  • Better treatment of wastewater. Soil is more effective at filtering. 

  • Reclamation of otherwise wasted nutrients.
