Water savings indoors can be achieved by installing low-flow toilets, faucets, and showerheads (all readily available at local hardware stores) and purchasing water-efficient dish and clothes washers. The following table shows the potential savings from these retrofits.
Potential Water Savings From Conversion to Water-Efficient Fixtures and Appliances
|Plumbing Fixtures||Water Use:
High Efficiency Models
|Per-Capita Reduction in Daily Water Use by This Fixture or Applicance|
|Toilets||1.6 gal per flush||5-7 gal per flush||58%|
|Faucets||0.5-2.5 gal per min||3-7 gal per flush||13%*|
|24-48 gal per wash||56 gal per wash||38%|
|Dishwashers||7 gal per wash||9.5-14 gal per wash||NSS|

* Estimated based on retrofitting faucets with aerators, not replacing the entire faucet.
It is also crucial to detect and correct leaks in toilets, faucets, and pipes and to turn off water when not in use during activities such as teeth brushing or while sudsing up in the shower.
Check with your local municipality on rebates for purchasing appliances that are water and energy efficient.
