Collaborative partnerships focus on cost-effective solution to allow agriculture to thrive while conserving Colorado River water
The Tier 1 Colorado River Shortage reductions we will be taking next year will most severely impact central Arizona agriculture. CAP, along with partners in Arizona and across the Colorado River Basin, has been researching alternatives with the aim of saving water and sustaining irrigated agricultural productivity. Thanks to a low-cost, innovative irrigation technology from an Israel-based company called N-Drip, a solution may be at hand in the form of low-pressure, gravity-powered micro-irrigation.
CAP and ADWR partner with Metropolitan Water District of Southern California to advance development of large-scale recycled water project
Building on increased collaboration on the Colorado River, water

partnership to advance development of one of the largest water
recycling plants in the country – a project that would help restore
balance to the over-stressed river.
