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.
Going green to save green
City of Lancaster, Pa., is integrating the use of green infrastructure with its
core public works practices to reduce the impacts of pollutant sources and
achieve cost savings. The city also is updating its long-term control plan to
reduce the frequency and volume of combined sewer overflows (CSOs) and address
its stormwater discharges.
The Banklick constructed wetland
major challenge facing water utilities is finding effective solutions to
improve water quality while meeting government mandates and maintaining fiscal
responsibility to their ratepayers.
In the process of developing strategies to
meet the goals of their wet weather consent decree, Sanitation District No. 1
of Northern Kentucky sought to identify innovative solutions that could meet
all of these objectives.
Banklick Creek wetland is one of these improvements. The 4.9-ha (12-ac) pilot
project, located adjacent to Banklick Creek, is designed to evaluate how well
natural treatment processes improve water quality and provide greater public
health benefits, compared to traditional control measures focused solely on reducing
wet weather overflows.
Ending courtroom struggle
January, the U.S. Supreme Court unanimously ruled to overturn a lower-court
decision in the case of Los Angeles County Flood Control District v. Natural
Resources Defense Council regarding stormwater flows discharged from the
district into the San Gabriel and the Los Angeles river systems. The ruling in
favor of the Los Angeles County Flood Control District brought an end to a
lawsuit that spanned 5 years, had made its way through several federal courts,
and could have changed the definition of “navigable waters” under federal law.
Coming in the next issue:
utility management is about ensuring performance to meet customer goals.
Sometimes the goal is ensuring sanitation services, and sometimes it is
providing adequate drinking water.
articles in the May issue of WE&T focus squarely on ensuring the flow and
supply of drinking water.
The first details a special-delivery groundwater well
field and conveyancesystem project
to quickly deliver an average of 37,854 m3/d (10 mgd) to a
relatively dry city plagued by unusually severe drought. Conditions required
fast action. If all goes as expected, work to alleviate critical water
shortages in Midland, Texas, will be wrapping up in early May — just 12 months
after the project’s launch.
second story features Hardin County, Ky., which, on the other hand, has taken a
long-term and evolving approach to managing its water resources. Beginning in
1999 a combination of bizarre, coincidental events put the district in a situation
in which no water utility wants to be — completely dependent on an auxiliary
source of water. Since then, the county has worked consistently to diversify
its water supplies and develop a safe and reliable drought-resistant supply of

A California utility’s need for flowmeter efficiency and accuracy led to creation of an in-house flow confirmation laboratory.
Rate increases in this economy?
The City of Los Angeles shows it can be done, with effective communication and stakeholder collaboration to raise fees for a 10-year capital improvement program.
A different disinfectant.
By switching to the use of peracetic acid for disinfection, a Florida city has eliminated disinfection byproducts in its effluent while handily complying with requirements for pathogen removal.
