In July of 2010, the Eastern New Mexico Rural Water Authority transitioned from a loose group of six cities and two counties to a new regional water utility authority – a sub-division of the state of New Mexico. This transition is a logical step in a 40 plus year journey to provide a sustainable water supply to the region. CH2M HILL's Greg Gates shares more details about the regionalization process and solution development for a sustainable water supply in Eastern New Mexico and how this can be applied to other regionalization projects in his World Environmental and Water Resources Congress presentation and on Access Water.
With over 9.5 million residents (2010) distributed across 14 major river basins, 159 counties, and over 500 cities, the establishment of the first comprehensive state-wide water management plan and its corresponding regional water planning process was an ambitious undertaking for the State of Georgia. Rick Brownlow, CH2M HILL Client Service Manager, shares the challenges experienced during the planning process and lessons learned in developing these plans in the latest Access Water and during his World Environmental and Water Resources Congress presentation.
In response to continuing increases in global greenhouse-gas emissions, California is projected to experience warming by 1.5-4.5ºC (34.7-40.1ºF) by the end of the twenty-first century. Although great uncertainties exist about future changes in long-term average precipitation rates in California, it is generally expected that extreme precipitation episodes will become even more extreme as the climate changes. A research group conducted a study to investigate potential changes in magnitude of floods of various return periods in the Sacramento-San Joaquin Valleys that might arise from projected warmer temperatures and changes in precipitation in the twenty-first century. Tapash Das, CH2M HILL Associate Water Resources Engineer, and Armin Munévar, CH2M HILL Project Water Resources Engineer, share more on Access Water and will present the results of the research in the paper, “Potential Change in Projected Flood Regime in California under Future Climate,” at the World Environmental and Water Resources Congress this Thursday.
Crossing Water and Energy Boundaries in the Middle East: Integrated Resource Planning For a New City
Several countries on the Arabian Peninsula are investing heavily in developing leading edge cities that embody a holistic view toward resource management of water, energy and carbon. To meet these goals in a financially viable manner, both horizontal and vertical infrastructure must be considered. CH2M HILL’s Voyage model is designed to calculate life cycle costs analysis and carbon footprints, and provide an optimized technology solution to meet business case economic considerations, incorporating total water management principles to manage the urban water cycle. Mark Anderson, CH2M HILL Senior Technologist and Project Manager, discusses the application of Voyage in the latest Access Water and at his World Environmental and Water Resources Congress presentation this week.
Total Maximum Daily Load (TMDL) programs are critical in attaining water quality goals and restoring impaired waters by calculating pollutant loads in a manner consistent with water quality standards. There is a great need to report valuable information on TMDL implementation activities and on the water quality improvements after TMDL development. During the World Environmental and Water Resources Congress, Dr. Harry X. Zhang, CH2M HILL Principal Technologist and Industrial Water Resources Lead, will present on the successful application of watershed modeling tools linking TMDL implementation with approved TMDLs for both an agricultural watershed in Virginia and an estuary watershed in Connecticut.
