    The sewage collection system for the community of Port Perry Ontario includes several sewage pumping stations conveying wastewater to the existing aerated sewage lagoons for treatment.  Initially the system originally included two sewage pumping stations pumping from the Community directly to the lagoons; the Water Street Pumping Sewage Station and the Cawker’s Creek Sewage Pumping Station. ...

  • North Creek pumping station, King County, WA

    The new North Creek Pumping Station in King County, Wash., had to maintain the Department of Natural Resources' national reputation for outstanding reliability. To make sure it did, the design team applied the most advanced pump technology and vibration prevention methods. And the designers and utility put extra attention on meeting operations and maintenance needs. "We included folks from ...


  • Deep soil mixing shoring system to construct a 60 MGD, 40 foot deep wastewater pumping station

    The City of San Mateo, CA operates three wastewater pumping stations on a 80' wide lot located in a residential area near San Francisco Bay. The age of the stations range from 12 to 50 years, the stations have difficulty pumping peak wet weather flows, and have structural and maintenance problems. For these reasons, a new station was proposed to replace the existing stations. The site layout is ...

  • 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 ...

  • Hydraulic Challenges of Designing for a High-Capacity and High-Head Pump Station

    King County is developing a new wastewater treatment plant to service a growing area of King and Snohomish Counties, Washington. To convey flows to the Brightwater treatment plant, the influent pump station (IPS) and a series of new tunnels and interceptors are being constructed. The plant IPS is located approximately 2.5 miles upstream and connected to the treatment plant via a tunnel containing ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Lift Station Odor Control Using CARUSOL Treating a Wastewater Collection System in a Mid-Western Township - Case Study

    Summary A mid-western township is responsible for operating and maintaining a combined sewer collection system consisting of 150 miles of pipeline and 28 pumping stations. The township does not treat the wastewater, instead contracting with a neighboring city for this service. The township has two final lift stations that transfer the collected wastewater to the neighboring system ...

  • There’s No Use Crying Over Spilled Sewage: Using Standby Lift Station Pumps to Prevent SSOs before They Happen

    Power outages and unforeseen mechanical failures create the potential for system distress and sanitary sewer overflows (SSOs) in wastewater collection and treatment systems. In accordance with a lawsuit initiated by Mobile Bay Watch (Mobile, Alabama), the Mobile Area Water and Sewer System (MAWSS) chose to install an automatic dry priming backup system to increase system reliability and enable ...

  • Detailed dynamic pumping energy models for optimization and control of wastewater applications

    Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this unbalance in the coupled submodels. The model is ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
