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.

This is a broad pump category that encompasses positive displacement pumps to pump sludge in ranges usually up to about 500 GPM. The choices of pumps vary from double diaphragm pumps, plunger pumps, double disc pumps, rotary lobe pumps, progressive cavity pumps and more.

In todays pump marketplace, there are generally two schools that operators and consulting engineers follow when specifying primary sludge pumps. The first option is Continue reading

Pumping Wastewater in Nassau County

Long Island Pump installation

Long Island Pump installation

Pumping wastewater in Nassau County NY poses unique challenges. First the county borders Long Island Sound to the North and the Atlantic ocean to the south which can bring variations in both weather and the types of wastewater that need to be pumped. Nassau County  is home to over 1.3 million residents with a mix of suburban residents and vacation properties.

The City of Long Beach, New York was impacted by Hurricane Sandy a few years ago.  The municipal wastewater treatment plant experienced flooding and equipment damage.  An additional challenge is a nearby recreation center that includes a golf center. With golf balls and other debris entering the sewage system, the pumps were requested to manage unexpected solids. Wastecorp was awarded the bid to replace an existing plunger pump to upgrade the existing infrastructure. Since the facility is so close to the ocean, a grinder was also installed to manage storm surge debris that will likely occur in the future. Continue reading
