Why Utah's water managers continue to prioritize supply-side solutions

Since then, Utah water managers have solved water supply problems by building large infrastructure projects. Today, Utah's population is growing rapidly, but the water supplies that enable its desert oases are not, and climate change is expected to make matters worse. This increasing tension between growing populations and dwindling water supplies is not unique to Utah. However, while other states in the region have implemented aggressive demand-side measures to conserve water, Utah's conservation efforts have been relatively minimal. Utah's history of water engineering, the cultural importance of agriculture, the precedent of federal funding for large water projects, and some of the cheapest water rates in the country make demand-side measures a tough sell for addressing water needs in Utah. However, supply-side projects are costly for taxpayers and for the environment, take decades to complete, and are based on unreliable forecasts of future water demand and uncertain water sources. It is time for Utahans to look past traditional supply-side solutions and embrace water conservation measures, requiring changes to the dominant water planning mindset. In order to do this, the state could take regulatory action, and both the state and LDS Church can act as water efficiency exemplars. It is also time for Utahans to become more involved in Utah's water planning and decide for themselves whether to continue attempting to conquer nature or to live within its bounds.by Chloe Schaefer.M.C.P
