Sewer Overflow Problem in Modern Cities
When we visit our customers at wastewater treatment plants and ask operators “what are your facility’s most pressing concerns?”, the answers we most frequently hear are ever tightening budget constraints and dealing with aging infrastructure. And this concern echoes not only in the United States, but in many parts of the world. So this is nothing new right? City budget problems have existed for years. Well, the problem is that aging infrastructure designed to treat sewage may not be equipped for rising urban populations and shrinking green space to protect us from harmful bacteria and other negative health effects.
A New York Times article highlights these concerns. For example, more than 9400 of 25000 American sewage systems have reported violating environmental laws by dumping partially treated human waste, chemicals and other hazardous materials in lakes, rivers and waterways. “This may contribute to more than 20 million illnesses each year in the U.S. alone from drinking water contaminated with bacteria and other pathogens that spread from untreated waste.”* When sewage systems overflow they may be discharged close to water intake points or public beaches which is of major concern.*
Komline Sanderson Plunger Pump
Many of our wastewater treatment plant operators looking to upgrade their sewage pumps to the next generation plunger pumps have a wide set of options for a no piping change or little alternation to the existing set up. New sewage pumps can help make the facility more efficient and productive. This is available to all plunger pump customers including competing makes like Komline Sanderson* and Carter* Plunger Pump customers.
With a 3 hp motor, and 4″ discharge. Mike D. from Fort Worth Texas illustrates a number of pump questions we get from public utilities operators.
“I am looking to replace 2 Komline Sanderson KS-9 plunger pumps at my wastewater treatment facility. The pump characteristics are 140 GPM at 90 ft head. We get some grit in our sewage and we have a grinder on the suction lines of both pumps. Current pump is duplex plunger pump general arrangement. What is your equivalent of this pump? Do I have to make piping changes to my effluent lines? And what other pumps do you manufacture that we could consider installing? .” Thanks, Mike D. Fort Worth, Texas
Well Mike, you have Continue reading
