The Problem of Space Constraints at Wastewater Treatment Plants

Space Saver Plunger Pumps

Space Saver Plunger Pumps

It’s a common problem faced by many wastewater treatment facilities’, how to select a pump to move heavy sludge with enough power and endurance to last through the long haul.  One solution to this problem is a pump with an in-line piping design like the Space-Saver plunger pump.  Many facilities have seen success with this pump especially those replacing a double disc, rotary lobe, or progressive cavity pump.

The Space saver plunger pump does not require a concrete base, which makes replacing any type of sewage pump quick and trouble-free. In most cases, the old pumps are simply replaced and the new Space Saver simply dropped into place.  The Space Saver is available with a 7”, 9” or 11” piston size and can transfer up to 140 GPM (8.8 lps) of municipal or industrial sludge.

In our case study feature, you’ll see a Memphis, Tennessee area sewage treatment plant which recently installed a Space Saver after trying double disc and progressive cavity pumps.  The facility operates this pump for at least eight hours each day and other than general maintenance procedures, the pumps have run perfectly.

Sewer Overflows Becoming an Increasing Problem for Cities

Sewer Overflow Problem in Modern Cities

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.*
