Going green to save green

Lancaster The 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


A 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.   

The 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


In 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.

Flow assurance

Water 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. 

Two 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.  

The 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 water.

  • Pipe dreams. 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.
