EVERLAST Wet well mounted pump station - Hazelwood West High School - Case Study

When a St. Louis area high school determined it needed to replace an underground pump station after nearly 40 years of faithful service, school officials implemented a best value approach to the project with a local design-build firm. They evaluated three options: (1) replace all of the pumps and valves in the existing buried pit, along with associated electrical and control work; (2) abandon ...

EVERLAST Wet well mounted pump station - Texas School District - Case Study

For most small to medium-sized operations groups like Klein Independent School District in the suburbs of Houston, the conventional choice of submersible wastewater pumps holds little wisdom. Above-ground pump stations reduce exposure to designated confined spaces, and associated safety requirements, allowing these groups to operate in a more convenient and cost-effective manner. “With the ...

Pumping Station Modifications to Comply with ANSI/HI 9.8 Improve Performance While Lessening O&M Requirements --- Two Case Studies

Oversized wet wells in wastewater pumping stations lead to the accumulation of grit, sludge and floatable materials. Trench-type wet wells in compliance with ANSI/HI 9.8, the American National Standard for Pump Intake Design, minimize wet well volume and facilitate wet well cleaning through periodic pump down operations. Two pumping stations, the Cross-Irondequoit Pump Station (CIPS), Monroe ...

STEM Drive Mixing system eliminates accumulation in wet well and allows removal of rags and grit at new headworks facilities - Carlisle WwTP - Penn, USA - Case Study

The Carlisle Regional Water Pollution Control Facility, a 7 MGD wastewater treatment facility, serves the Borough of Carlisle and portions of North Middleton, South Middleton and Middlesex Townships. Constructed in 1981, the raw wastewater enters the facility through a gravity sewer over 20 feet below grade. The raw wastewater discharges into a pump station wet well, where it is lifted to the ...

Hydraulic modeling - Bethel Park Municipal Authority - Case Study

Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions. Many existing plants already have a minimal amount of head available for passing peak flows through the system, which can ...

NFPA 820 Compliance in Wastewater Treatment Plants

Wastewater treatment plants are essential structures in cities and small communities. Such facilities are closely monitored by several professional institutions, such as OSHA and the NFPA. When it comes to the latter group, guidelines set forth in NFPA 820 are regulations that dictate fire hazards in such facilities. Fire related accidents in wastewater treatment facilities are uncommon. However, ...

Wet Well Mixing Success With The GridBee® AP500

The GridBee® AP500 wet well mixer for lift stations officially launched in April 2015. From its very first installation it became clear this little mixer had some huge benefits in the world of lift station wet wells. Even then we didn’t have a true picture until bits and pieces of success story after success story started to make it our way. We thought we’d share a couple of them ...

Computation Fluid Dynamic Modeling of a Proposed Influent Pump Station

Traditionally pump intake hydraulics have been investigated using scale physical hydraulic models. Computational fluid dynamics (CFD) is a rapidly improving technology that in some cases can be used as a cost or time effective alternative to traditional physical model methods for evaluation of pump intake hydraulics. This paper presents a case study on the use of CFD modeling to re-evaluate and ...
