Dishwasher using only water tanks

Hi,
I am building a new home which doesn't have running water, only water tanks. I want to have a dishwasher. Does anyone know if there will be any problems running the dishwasher.

Dishwashers not only need a water supply, but need water under pressure.

So you would need a pressurized tank using a pump from your tanks to the holding pressurized tank.

Theoretically, if the tanks had enough "head" ie, uphill far enough, you might not need a pump, but if you're using rainwater from the roof, there's not going to be enough pressure.

Your washing machine will probably be an issue too. Most solenoid valves found in dishwashers and washing machines require a fair amount of water pressure to operate.

What you should do, and I'd assume building regulations would require is a pressure pump, something like this (I'd assume it would have a tank with a bladder, but this is the general idea:

"Most solenoid valves found in dishwashers and washing machines require a fair amount of water pressure to operate. "

The valves are electric, though they often have a large pressure drop when they are open (they are typically pretty small bore valves).

A bladder type pressure tank should take care of the problem.
