Efforts to reduce nutrient levels are shifting and becoming more widespread as water and wastewater utilities work to improve effluent and adhere to regulations
Nutrient pollution and the resulting excess of nutrients in waterbodies continues to plague aquatic environments around the world, threatening waterways, fish and plant life — and even public health. The runoff of phosphate and nitrogen from farming, stormwater, wastewater treatment plant discharges and other sources into waterbodies continues to unbalance ecosystems, resulting in toxic algal blooms and hypoxic dead zones.
Nontraditional delivery methods are gaining ground when commissioning large-scale water projects
There are an estimated 240,000 water main breaks every year in the United States, and those ruptures waste between 14 percent and 18 percent of the nation’s drinking water. Aging infrastructure is primarily to blame, as an estimated 40 percent of U.S. water and wastewater pipes are beyond their life expectancy, notes a recent article in WaterWorld.
When it comes to asset management, water utilities tend to weight their efforts toward preventive maintenance
Water utilities the world over faced with challenges, including of increasing demand, falling revenues and climate change. While building new assets remains part of the solution, enhancing the performance of existing assets is more important than ever before.
Consider this scenario: When planning a large power plant project, designers find that two large hills – some 8 million cubic meters of soil and hard rock – will literally need to be dug out and moved, truckload by truckload, to create the flat space necessary for the plant’s buildings and support facilities.
On Thursday, May 9, representatives from Bechtel Innovate, along with a Bechtel university relations representative visited the University of Maryland in College Park, to take part in the university’s Clark School Department of Mechanical Engineering Design Day. Design Day highlights the talents and creativity of mechanical engineering students in the Integrated Product and Process Development Course. 33 teams of senior-level students presented project prototypes built to solve selected engineering problems.
Completion of Energy & Water Operations Center (EWOC)
One of the most integral components of the MCAS Miramar microgrid is now operational. Construction is complete for the new Energy and Water Operations Center (EWOC), where the microgrid system will be monitored, controlled and managed. The EWOC provides operators with direct control of integrated microgrid control system, utilizing Schneider Electric’s OASyS SCADA software, as well as other utility and energy control systems.
