I think OP asks the milky white type of water that takes some time to clear up. That's caused by the pressure in the main pipes. Water needs pressure so it can travel from the reservoir to your home.

The Short Answer

I think OP asks the milky white type of water that takes some time to clear up. That's caused by the pressure in the main pipes. Water needs pressure so it can travel from the reservoir to your home. Increasing pressure makes air more soluble and it mixes in easily. Once it is near your faucet, the water loses pressure and the dissolved air separates, leading to super small bubbles that create a milky white appearance as these bubbles also disperse light (similar to fog effects).
