The average rainfall per week in May and Oct is 3/4 inch, in June is 2 inches, July is 2 inches, August and Sept is 1 1/4 inch. If this grass does not do well with over 3/4 inch a week you are in big trouble during our several months of rainy season and certainly would not be running your irrigation for your lawn at all those months.
Scott's [the grass company] says this about watering:
You should water your Scotts® ProVista™ turf in the same way you would for the relevant conventional varieties (e.g., St. Augustinegrass Floratam and Kentucky Bluegrass)Drought tolerance and water usage have not yet been fully tested for Scotts® ProVista™.
Given that ® ProVista™ was bred to deliver improved plant efficiency, we are actively testing the turf to quantify drought tolerance and reduced water usage.
I would have thought Scott would have established the water need of the grass it was selling before it was marketed. Interestingly it does say that during the summer this grass needs to be cut only 1/2 as often as other grass types and less fertilizer. That should save you on mowing costs as you don't need to have it done weekly.
Scotts® ProVista™ was developed to require half the mowing of the relevant, conventional turf varieties (e.g., St. Augustinegrass Floratam and Kentucky Bluegrass).
Further, given its dense and slow growth, Scotts® ProVista™ has a deep, green color, thrives in both sun and shade, and requires less fertilizer to stay healthy and green
