The main lift station serving the waste water treatment plant in Morgan’s Point, Texas, continually experienced problems with its three standard non-clog pumps. The pumps frequently clogged when rainfall totals reached or exceeded 2 inches. Shop rags, pieces of 2 x 4 lumber, plastic bottles, gloves, and wet wipes all commonly clogged the pumps when the standard demand increased. Pump removal, unplugging, and recurring repairs were required, but the service company was not always available for immediate assistance, causing problems for residents serviced by this lift station.
During 2017’s Hurricane Harvey, the wettest tropical storm on record in the United States, over 52 inches of rain fell in the Houston area. The Vaughan pumps ran continuously for 72 hours with no plugging incidents and no problems while pumping over 2.5 million gallons of unscreened sewage through the lift station. It never flooded and none of the 150 homes served by this lift station experienced sewer back-ups.
Condensation, build up, obstructions and silt can cause difficulties in making reliable level measurements in lift station wet wells. New trends in low cost radar units solve these problems.

The XRCP is Sulzer’s premium range of recirculation pumps, specifically designed for efficient pumping and recirculation of activated sludge in the denitrification/nitrification process of a wastewater treatment plants. These compact and easy-to-handle pumps are equipped with Premium Efficiency motors and designed for large flows and low heads. Compared to conventional axial flow pumps, recirculation pumps do not require expensive structures in the tank, such as inflow chamber and a large rising pipe.
The RCP is Sulzer’s standard range of recirculation pumps, specifically designed for pumping and recirculation of activated sludge in the denitrification/nitrification process of a wastewater treatment plants. This compact and easy-to-handle pump is efficient and reliable. RCP pumps are designed for large flows and low heads between 0.1 and 1.8 m (4 to 71 in). Compared to conventional axial flow pumps, recirculation pumps do not require expensive structures in the tank, such as inflow chamber and a large rising pipe.
For the past 10 to 15 years, wastewater treatment operators have faced increased clogging issues related to baby wipes, disposable diapers, rags, and other foreign debris. At the same time, the use of low-flow toilets has increased the solids concentration of sewage flow. This discussion with Brad Jernigan and Christina Foster from Pentair addresses differences between how grinder pumps (low flow/high head) and chopper pumps (higher flow/lower head) can benefit that situation. They also compare the advantages of how axial-cutter design vs. radial-cutter design can aid in shredding large debris, bit by bit, without sucking it into the body of the pump where it can clog and shut down the unit.
Many water and wastewater treatment plant operators have a desire to ‘see’ and manage key systems beyond the reach of their plant walls and in-house SCADA systems, such as wastewater lift pumps or water distribution pumps. In this Water Talk session, Dave Stout and Ryan Hancock of In Control Technical Solutions discuss an answer that’s as simple as connecting a power cord and two wires. It employs a self-contained cellular modem that any utility can self-install — at a fraction of the cost for traditional remote cellular solutions — and use to monitor remote resources as part of their main SCADA system.
Control gates are used throughout the water and wastewater fluid handling process at pump stations, head works, purifiers and a variety of other locations. Beyond application, head pressure, solids content and placement are all critical factors in evaluating what type of control gate will best meet your needs.
