One example comes to mind. Flow restrictors on faucets.
Supposing I'm washing the car. I need five gallon bucket,
half full of hot water and soap. If I half-fill the bucket
off unrestricted faucet, it half-fills in about a minute.
And suppose I half-fill the bucket on a sink that's got a
1.5 gallon per minute aerator, on it. It takes much longer
to half-fill the bucket. Now, for 10 bonus points, and one
letter grade increase. How much water was saved by using the
flow restricted faucet, and waiting several minutes to
half-fill the bucket?

And how much extra did that flow restricted faucet cost me,
to install?


Flow restricted faucets are intended to be fitted hand washing basins
and nowhere else. Eg in bathrooms.
There are then considerable savings.
