Water is a precious resource.  These days, depending on where you live, it can be downright scarce and also rather expensive.  They charge you to get it and also to get rid of it (sewer fees).  There are ways to use less.  On demand water heaters, Energy Star appliances.  Better toilets that use less water.  You can design your landscape plan to consume less water.  You can make changes in your irrigation system to use less water.  Moisture meters that only allow watering when necessary, and drip irrigation instead of spray irrigation all are ways to save this precious resource.  Water can be collected through a gutter system in sisterns and reused for irrigation, and in some locals even used to flush the toilet.

Some of the products that I used in my home are shown above.  My faucets are Moen.  My water saver toilets are by TOTO. They have the water sense label.  I've got a Rinnai water heater. It runs on propane and only comes on when you actually need the water.  That control goes inside and you can set the temperature that way.  They tell me that I can hook up one of those computer battery backups to it and it will operate even when the power goes out.  That may come in handy in a storm.  The water saving front load washer and dryer combo are from Whirlpool. Those storage drawers underneath raise the units up so they're easy to get into.  You want an energy star dishwasher.  Mine's a Kitchenaide and it's wonderfully quiet.  You need that in an open kitchen design.
