Hard water from sprinklers and chlorinated water from swimming pools, are detrimental to the glass in your new windows. Once the hard or chlorinated water stays on your windows for a few days, it will be almost impossible to remove.
For your sprinklers, having your landscape professional direct all spray heads away from your windows is the best solution. Additionally, applying RainX or a similar product can help protect the glass for the harmful effects of hard water.
For your pool, there are products such as Polaris Tailsweep Pro that can eliminate the wild spraying all over the sidewalk and windows of your home.
