Developing science-based, engineering solutions, guided by robust understanding of natural and human engineered systems.

energywaterIn many areas of the United States and multiple regions of the world, competing demands for fresh water outweigh sustainable supply. Water issues increasingly limit economic development, impact interdependent infrastructure (such as energy and agriculture), and are a fundamental source of conflict. The primary objectives of the Sandia Water Initiative are to:

  • Increase the safety, security and sustainability of water infrastructure through the development of advanced technologies that create new water supplies
  • Decrease demand through water-use efficiency
  • Provide decision-informing tools to the institutions responsible for balancing supply and demand

Sandia National Laboratories partners with the United States Environmental Protection Agency whose mission is to protect human health and the environment. Through a partnership with the EPA’s National Homeland Security Research Center (NHSRC), Sandia developed a risk assessment methodology for assessing the vulnerability of the physical infrastructure of water systems in our nation’s largest cities after 9/11. Since then, Sandia has worked with EPA-NHSRC to develop a number of software tools for enhanced monitoring of water distribution networks and response to contamination events in these networks.
awwalogoIn a partnership between the American Water Works Association (Awwa) Research Foundation (AwwaRF) and Sandia National Laboratories, the Environmental Protection Agency (EPA) undertook a program in 2000 to improve security at water utilities across the United States. Sandia has also worked with AwwaRF (now the Water Research Foundation or WaterRF) to assess the impacts of water quality sensor precision and accuracy on the results of water quality event detection algorithms.
publogoThrough the use of Sandia’s CANARY event detection software, Singapore’s national water authority PUB has made a quantum leap in their utility’s practices to uncover water quality events. By partnering with Sandia, PUB has dramatically improved their ability to respond to water quality changes and allows them to arrest poor quality water before it reaches consumers. Ongoing work with PUB is focused on real time identification of contaminant source locations for grab sample data.
texasamlogoDr. Carl Laird and his research group in the Chemical Engineering Department continue to work with us on computational tools for analysis of water distribution networks. Current work being done at Texas A&M University is focused on efficient methods for solute transport in networks and optimization of sample locations during a contamination event.
