New approach to project delivery

Feature 2 - Jurich - art The South Coast Water District (Laguna Beach, Calif.) operates the Beach Interceptor Sewer Tunnel in South Laguna, Calif. The pipeline running through the tunnel conveys, on average, 4.7 million L/d (1.25 million gal/d) of wastewater. Approximately 85% of the interceptor’s flow comes from an upstream force main; the remaining flow enters the pipe through 80 residential connections along the tunnel. But the tunnel itself is in an advanced state of deterioration. test

 

Bursting with possibility

Feature 1 - thomas - art

Asbestos, a naturally occurring mineral fiber, was used extensively in many building materials, including pipe. test

Now, as these pipes reach the end of their useful lives, replacing them becomes a costly challenge because asbestos-containing materials are controlled carefully regulated. Pipe bursting, however, could be an effective technique to replace these pipes.

25 Years of Operations Excellence

WEFTEC® 2012 marked the 25th anniversary of Operations Challenge. And under the bright, buzzing convention center lights, Operations Challenge competitors bent over their tasks with complete focus and control apparent in every movement. Coaches and other team members called out tasks, the time on the clock, and encouragement.

As competitors moved quickly around each other to complete their specific set of tasks, one thing was obvious: Each event required the right mix of extreme planning, teamwork, and training to make the recipe for success.

In Division 1, Terminal Velocity from the Virginia Water Environment Association earned first place for the third time in 3 years. In Division 2, the ReWa Blackwater Bruisers from the Water Environment Association of South Carolina earned first place — this was the first win for any team from Renewable Water Resources in Greenville, S.C.

Getting the Most Out of Biosoldids

Whether it’s as a soil amendment or as a fuel, biosolids should be regarded as a resource. When it comes to land application, ensuring environmental and public safety is essential. That’s why the Canadian Council of Ministers of the Environment in 2009 sponsored a project to document the occurrence of organic microconstituents (MCs) in biosolids and septage. Representing 14 environmental agencies, the council is using the results of the study to further its assessment of the risk of MCs in managed land application, land reclamation, and the production of commercial and soil amendments.

On the energy side, alchemists of the 21st century are at work. But the “gold” they seek is energy – particularly green energy. Effective use of incineration to reduce the volume of wastewater solids updates the zero-energy aspirations of the modern alchemist, while sound science and engineering negate the need for magic.
