Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.
Look Before You Dig
When the Kearny (N.J.) Municipal Utilities Authority (MUA) needed to construct a 2.4-km long (1.5-mi-long) force main and two pump stations in an industrial area that already had two interstate highways, multiple underground utilities, and tidal wetlands, the project team needed to think creatively. A little research revealed an abandoned gas main that could serve as a host pipe for the force main, which enabled the project to be constructed faster, safer, and less expensively. It also minimized installation effects on traffic and the environment.
Factoring Condition Assessment and Asset Management Into Capital Planning
With limited funds, it is more important than ever to invest capital for the maximum benefit. Condition assessment is the process of determining the overall health of an asset — a process that sounds simple but in reality is not rigorously implemented or commonplace in the industry.
Indeed, new condition assessment criteria and approaches are on the leading edge of development in both the equipment maintenance and reliability communities.
Michigan’s Blue Water Economy
Ask a dozen people what they think of when they hear the word “Michigan,” and many will mention the automotive industry. Only a few will remember the reason the ailing industry made the state its home in the first place.
“It was the water,” explained John Cherry, the state’s lieutenant governor, who grew up hunting and fishing in Saginaw Valley on Michigan’s lower peninsula. “The Great Lakes made it possible to bring all the necessary manufacturing resources to one location.”
With an unemployment rate of more than 14% — the highest in the country — the state is now turning its face to the water again. Cherry is leading a statewide economic development initiative with the dual purpose of protecting Michigan’s waters and transforming the traditional manufacturing-centered state into a leader in water technology.
Coming in the next issue:
Everyone wants to get more for less. In the May issue, you’ll find numerous ways to use the fewest resources for the greatest benefit — in new equipment purchases, biosolids drying facilities, membrane bioreactor operations, and various optimization projects. Featured success stories include:
- A Florida utility that switched to a new type of blower that provides more efficiency over a larger operating range. Since aeration processes can account for 60% or more of a facility’s overall power consumption, making them more energy-efficient can greatly reduce energy consumption and costs.
- A California biosolids processing facility where landfill gas was tapped to fuel thermal dryers to produce a Class A product. The landfill gas provides all of the energy for the drying facility as well as extra to sell back to the grid, and the biosolids are used as daily cover material for the landfill.
- A Virginia treatment plant that adopted and integrated a fixed-film activated sludge system to increase its capacity and meet strict new nitrogen requirements without building any additional tanks.
- A Wisconsin utility that managed to find enough capacity in its existing facility to avoid building a new plant, improve effluent quality, and reduce energy costs.
