CalWater Solutions was created in direct response to the current water scarcity dilemma here in California by promoting integrated design principles and practices in every project we design, install or retrofit. Currently 82 percent of California is either in an “Extreme Drought (D3)” or “Exceptional Drought (D4)” classification labeled by the National Integrated Drought Information System (NIDIS)
