Geotubes Fixing Finland's Lake Gallträsk

0
Lake Gallträsk, situated 15km west of Helsinki, used to be a popular recreational area with beaches and clear water. Unfortunately, it has suffered from major strain caused by habitation and industry. The lake is now being cleaned with a dredging program that it is utilizing Geotubes from TenCate. Roughly 26,000 m3 of silt will be removed from a 2 hectare area and pumped into a network of 12 Geotubes. To date, the lake's oxygen level is responding very favorably to the treatment.

Lothar Bestmann, Inventor of Sustainable Waterways Construction Measures, Turns 80

0
Mr. Bestmann, a Hydraulic Engineer with a green thumb, is recognized for pioneering the use of synthetic geotextiles on major marine construction applications in the 1960s, as well as his later inventions of numerous methods for addressing construction, habitat, and water quality on waterways, including specialized use of biodegradable materials to aid plant establishment. In addition to holding patents for many innovations such as floating breakwaters, artificial habitat islands, revegetation modules, and nutrient removal systems, Mr. Bestmann provided planning and design consultation globally through his firm until his retirement. Beginning over 20 years ago, he was tapped by the US Army Corps of Engineers and the Natural Resources Conservation Service to provide international technology transfer to assist in the adoption of engineering and construction practices compatible with sustainable water and habitat management.

Tempe Town Lake Gets New Inflatable Dam

0
After a failure one of the bladders in Tempe, Arizona's inflatable dam on Town Lake, the manufacturer has supplied replacement bladders. The new dam is warranteed for five years--a big change from the first dam, installed in 1999. That dam was specified to perform for 30 years but failed after just over 10. The city is debating a more permanent dam for the near future. Learn more here.;

New Focus for Duke Energy and UNC Off-Shore Wind Farm Research

0
Duke Energy Carolinas will no longer pursue a plan to place up to three demonstration wind turbines in the Pamlico Sound. Instead, the company and the University of North Carolina at Chapel Hill will refocus their collaboration to study and help enable large-scale offshore wind development on the ocean side of the North Carolina coast.

An Alternative for Alternative Energy

0
Conventional scour protections for off-shore installations are difficult to install and secure. Currents complicate foundations, creating a situation in which the installation will not be stable in the long term. Deep foundations are prohibitively expensive. In the growing wind farm sector, the large, heavy turbines must be protected against the erosive effects normal and sudden, strong, storm-induced currents. A durable and effective alternative has been found for securing these off-shore turbines: NAUE Soft Rock®.

From Anthrax to Greenroof

0
A New York City postal processing facility that was contaminated during the 2001 anthrax attacks is now the site of the largest "green roof" in Manhattan. The 65,000-square-foot roof area and other new energy-saving measures at the site have saved the Postal Service more than $1 million in energy expenses so far. The total installation cost roughly $5 million. Learn more here.;

Flex and Protect: Controlling Scour at Pipe Outlets

0
Controlling scour at storm water pipe outlets can be difficult based on the turbulent nature of the discharging storm water. Take into account the often odd-shaped outlet dimensions, and product selection and installation can be difficult. Until recently, rock was used as the main source of scour control at pipe outfalls, but rock can be limiting in that it cannot offer a vegetated design and is often difficult to maintain. North American Greens ShoreMax™ soft revetment scour protection mat was introduced recently with the intended use of providing high-performance supplemental scour protection. Learn more.

The closed A and L Salvage site in Lisbon, Ohio is nearly capped. With about 25 percent of the synthetic membrane or plastic cap in place, the 42-acre project is expected to be finished by the end of October. In addition to the 40-mil geomembrane, 18 inches of dirt and grass will cover the hillside with elevations between 80 to 100 feet. Learn more here.;

Abu Dhabi secures water supply

0
The Abu Dhabi Water and Electricity Authority (Adwea) is close to awarding the contract for a landmark water storage project that will create a three months emergency supply for the Emirate’s one million inhabitants. Three basins will be constructed, filled with gravel and topped with a ‘geotextile’ cover over a period of 30 months. The cover will prevent evaporation and contamination. When completed, the five meter deep basins will allow water to seep into the groundwater via PVC pipes. Learn more here.;

Bringing a Pond Back

0
Monument Valley Park in Colorado Springs, Colorado once had a beautiful pond. But with the city under budget constraints, management of the pond was suspended. The water slowly drained back into the groundwater, leaving behind an empty pond bed. The city's parks and trails manager is evaluating the possibility of installing an EPDM pond liner, or perhaps some clay, but nothing will be considered until the money is available. It's possible that some late summer rain will relieve the parks of irrigation costs, and if so the money might be available to fix the pond. Learn more here.;

NZ Mining Opponents Want Liners

0
Mining operations in New Zealand are underbonded, many are complaining. Opponents of mining activities are even citing the low bonding issues as evidence of poor enviornmental controls. One project that has been cited is the Newmont Waihi Gold's final bond on the Martha open pit mine. It was capped at $10 million. Watchdogs contend it should have been $100 million, and if it had been it would have had more stringent controls such as geosynthetic liners on the tailings dam. It only has clay. Any environmental damage to the site greater than $10 million will have to be paid for by New Zealand government agencies. Learn more here.;

A new hydrogen sulfide gas collection system at the Sarpy County Landfill (Nebraska), expected to eliminate the foul smell that's plagued neighbors for years, is scheduled to be finished by late October. Blue Source/CII of Utah was hired by the county last year to install and operate the gas collection system, which includes several extraction wells and a main pipe. The nearly $1.5 million system comes at no cost to taxpayers. This is the latest step, following attempts to use synthetic covers over portions of the landfill. Learn more here.;
