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.
The pumps that operated at the septage receiving wetwell at the Valley Forge Sewer Authority’s collection system in Phoenixville, PA were constantly clogging.
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.

Albion, MI, completed the update of several components of its four-MGD plant in the fall 2017. Afterwards, the plant superintendent became interested in testing the impact that optimizing his mixing might have on other aspects of his conventional activated sludge process with enhanced biological phosphorus removal. Read the full case study to learn how the test showed that there can be dramatic opportunities for right sizing mixer thrust, when the equipment is available to take advantage of it.
When the Metropolitan Government of Nashville and Davidson County received odor complaints from a residential subdivision, Evoqua provided a rapid, cost-effective solution.
A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. DO2E representatives suggested that the City of Taylorville (IL) use their proprietary digesters equipped with an ozone (O3) capability to remove this problem from our system.
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. By Paul Mercier, Regional Manager for OEM, Utility and Energy Markets, FreeWave Technologies, Inc.
Lift stations are remote pumping facilities that move wastewater from lower to higher elevation. Monitoring lift stations is important to collection system operators.
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.
