SOFIA - Circ 1182 - Excerpt - Florida Everglades. The Everglades ecosystem includes Lake Okeechobee and its tributary areas, as well as the roughly 40- to 50-mile-wide, 130-mile-long wetland mosaic that once extended continuously from Lake Okeechobee to the southern tip of the Florida peninsula at Florida Bay.
Since 1900 much of the Everglades has been drained for agriculture and urban development, so that today only 50 percent of the original wetlands remain. Water levels and patterns of water flow are largely controlled by an extensive system of levees and canals. The control system was constructed to achieve multiple objectives of flood control, land drainage, and water supply. More recently, water-management policies have also begun to address issues related to ecosystem restoration. 2011 Excellence in Environmental Engineering and Science Competition Winners. 2011 Excellence in Environmental Engineering and Science™ Competition Winner Grand Prize - Environmental Sustainability Entrant: CH2M HillEngineer in Charge: Wayne D.
Murphy, P.E.Location: Morrow, GeorgiaMedia Contact: Jodie Willson Click images to enlarge in separate window. 2011 SAB Awards Winning Project - Shepard Environmental Education Centre. Located on the outskirts of Calgary, the Shepard wetland is part of a 227ha storm water management initiative to improve the quality of storm water entering the Bow River.
Development of this site also creates an open water habitat for wildlife. It is a regionally significant migratory and breeding habitat for waterfowl, and will provide important connections with surrounding wetland areas. Jury Comments: Designed as a constructed wetland for stormwater management and as a public environmental education centre, the project is an extraordinary and beautiful example of the integration of landscape design and architecture.

Wetland. Marshes develop along the edges of rivers and lakes.
Many species of frogs live in wetlands, while others visit them each year to lay eggs. Snapping turtles are one of the many kinds of turtles found in wetlands The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth.  International conservation efforts are being used in conjunction with the development of rapid assessment tools to inform people about wetland issues.
Blumberg Engineers Ecotechnologies. Dow Helps California Convert Sewage To Drinking Water. Filtered sewage served for decades as a way to irrigate farm fields and golf courses, but getting the public to accept it for drinking and cooking proved to be a tall order.
As climate change wreaks havoc on environments and water supplies, however, the cost of importing drinking water will climb. Water-strapped governments, meanwhile, will need to find a solution. Turning sewage into drinking water gains appeal as drought lingers. It's a technology with the potential to ease California's colossal thirst and insulate millions from the parched whims of Mother Nature, experts say.
But there's just one problem — the "yuck factor. " As a fourth year of drought continues to drain aquifers and reservoirs, California water managers and environmentalists are urging adoption of a polarizing water recycling policy known as direct potable reuse. Reclaimed water. Samples of different types of (waste)water, starting with raw sewage then plant effluent and finally reclaimed water (after several treatment steps) Reclaimed water or recycled water, is former wastewater (sewage) that is treated to remove solids and impurities, and used in sustainable landscaping irrigation, to recharge groundwater aquifers, to meet commercial and industrial water needs, and for drinking.
The purpose of these processes is water conservation and sustainability, rather than discharging the treated water to surface waters such as rivers and oceans. In some cases, recycled water can be used for streamflow augmentation to benefit ecosystems and improve aesthetics. One example of this is along Calera Creek in the City of Pacifica, CA. The definition of reclaimed water, as defined by Levine and Asano, is "The end product of wastewater reclamation that meets water quality requirements for biodegradable materials, suspended matter and pathogens.
BioScience. Authors Walter H. Adey (firstname.lastname@example.org) is a research scientist in the Department of Botany at the National Museum of Natural History, Smithsonian Institution, in Washington, DC. Patrick C. Feature: Building Wetlands for Clean Drinking Water – Cool Green Science. Can building wetlands reduce dangerous high nitrate levels and thus provide clean, safe drinking water for thousands of people? Yes. But, when it comes to ensuring clean water, not all wetlands are created equal. Biologists know how to restore great wetlands to draw in ducks and shorebirds. Performance Study on the Constructed Wetland for Clarification of Polluted Wu-Luo River Water. J. Environ. Eng. Manage., 18(5), 345-354 (2008) Small Towns Build Artificial Wetlands to Treat Sewage. SCIENTISTS are helping communities achieve low-cost sewage treatment by designing and building artificial marshes that can clean sewage as well as, or better than, conventional treatment plants while providing other benefits to wildlife and the environment.
A number of towns in the Tennessee Valley and in rural Pennsylvania have built wetlands to treat their municipal waste, raising the quality of the water that re-enters streams and reservoirs and improving the aesthetic appearance of sewage plants. Proponents say the most significant advantage of the wetlands systems is cost. The construction cost of such a system is estimated to be one-tenth to one-half that of conventional sewage treatment plants, and because wetlands essentially maintain themselves, purifying water through natural processes, they are far less expensive to operate.
As a result, more and more small communities are looking to artificial wetlands as the answer for sewage disposal. Constructed wetlands design manual – Melbourne Water. The manual outlines our requirements for best practice constructed wetland design. It will support consistent delivery of high quality constructed wetlands across the Port Phillip and Westernport region. The final draft has been prepared based on valuable customer feedback and comments.
Guidance note To assist the development industry, we have created a guidance note for interim use of the draft Constructed Wetlands Design Manual.
