Reuse Your Gray Water

"Don't flush with the clean stuff"

Big image

1/4 of all water used in a house goes down the toilet

Standard toilets use 1.6 gallons per flush, while older toilets can use as much as 3.5 to 7 gallons per flush.

Storage and Reuse of household water could reduce water usage by 25%

Waste water from sinks, showers and clothes washers (collectively known as gray water) could be stored and pumped or gravity fed back to toilet tanks and reused to flush waste.

These all produce Gray Water (water mixed with soap, etc..)

The water from these areas could be stored in tanks and plumbed to refill toilets in the same house

Flushing the toilets with water that has already been used means you save water .....and $$

Recommendations for the Future:


  1. Replace older toilets with low water units
  2. Adjust building codes to accommodate/require gray water systems
  3. Build prefabricated systems for easy installation
