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.
Designing communication, one link at a time
While communication challenges are universal, medium-size to large plants with multiple shifts and multiple crews on each shift are particularly susceptible. Operations structured as silos are even more prone to this problem.
Don’t let your model sit on a shelf
The Sanitation District No. 1 of Northern Kentucky (SD1; Fort Wright) wanted to get more bang for its buck.
Having invested a significant amount of time and money to produce a detailed hydraulic model, SD1 worked to ensure that this tool moves beyond capital planning to support day-to-day operations and decision-making. SD1 developed a plan to keep the model updated and identified several tasks that could be used to support day-to-day uses.
State of the Industry
WE&T’s annual state of the industry includes perspectives on the economy, pending legislative and regulatory matters, sustainability, and technology related to the water quality industry.

SSOs: the common enemy
In theory, providing enough capacity to deliver wastewater to the treatment plant sounds straightforward. But then the service area grows, and the older pipes start to let in a little extra flow, and the rains come. Without ongoing efforts, sanitary sewer overflows aren’t far behind.
Find out how Little Rock, Ark., built peak flow attenuation facilities to eliminate SSOs during its 2-year storms (about 4 in. of rain in 48 hours). The solution involves more than just storage; the utility now has the ability to transfer excess flows to its second wastewater plant.
Also in this issue, read about the successful collaborative planning, design, and construction process that a Wisconsin utility used to balance competing needs while developing a storage interceptor sewer project. The collaborative process used led to an optimized solution, accurate cost estimates, and public awareness of the project. The bottom line: The project was completed on time and under budget.
Simple steps for thicker solids
Solids thickening and hauling are big expenses. Getting the water out of the solids keeps dollars in the budget. Sometimes, simple steps are all that are needed to make the difference. For example, a small, privately owned wastewater treatment facility cut its solids hauling costs by 50% by installing a do-it-yourself settling and decanting system that uses simple components. The system also includes a live-feed video camera that enables operators to visually monitor and control the decanting process from anywhere.
Keeping track of polymer expenses also makes good “cents.” Learn the steps to implementing a simple and effective polymer quality assurance program.
