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.

Smaller Oklahoma city upgrades their wastewater treatment plant’s sludge handling system using the latest intelligent equipment. The new pumps went into service in April and May 2017 and the staff is thrilled that they have experienced no clogging.
A northern New Jersey town decided to upgrade their main station utilizing the same equipment that has provided them with decades of reliable and trouble free service. When replacement options arose, the city immediately elected to stay with Flygt due to their positive experience with the quality and reliability of the equipment, combined with the availability of local service.

In wastewater collection systems, raw sewage flows through gravity sewers to lift stations, which transfer the waste from lower elevation to higher elevations and eventually to a treatment plant. By Endress+Hauser, Inc.
As the world becomes increasingly connected, the integration of smart devices and tools, such as sensors, process control devices, security cameras, for example, have increased the need for well-established, secure machine-to-machine (M2M) communication and networking solutions. Many companies depend on effective communication technologies to reduce overhead costs and improve their bottom lines.

Powerful Pump Monitoring for Optimal Lift Station Performance. Trimble Unity software combined with the Telog wireless, battery-powered, multi-channel recording telemetry system provides a GIS-centric cloud and mobile platform for monitoring lift station pump on/off cycles along with sump levels. Clamp-on current sensors monitor pump run on/off to one second resolution.
In the fields of water and waste water technology, submersible pumps represent a viable economic and technical alternative to conventional, dry-installed pumps. In particular, they offer a number of handling advantages during maintenance and installation work, a factor of increasing importance in times of general staff cutbacks by operating companies.
3M Liqui-Cel Membrane Contactors have a long history of improving a variety of water treatment systems by adding and/or removing dissolved gasses. 3M Liqui-Cel Contactors were recently selected to be used in a municipal environment to improve water distribution efficiency while reducing capital and operating costs.
