The Fox First Flush System automatically takes the first flush of dirty water to treatment when it rains. We could not use a roof as some of our equipment is to big, the Fox FF600 is perfect for the job. ...

  • City of Grand Rapids – Michigan, Usa - Case Study

    In order to get a better understanding of the infiltration and inflow into their newly separated sanitary sewers, Grand Rapids engaged Xylem in utilizing BLU-X, a real-time decision support system consisting of smart sensors and actuators that track conveyance capacity. Grand Rapids, MI is a community that has garnered accolades in the clean water industry for taking ...

  • City of Ottawa Tackles System Overflow and Flooding with Tempest Inlet Controls Case Study

    Over the past few decades, rain events throughout North America have become more frequent and substantial. The combination of increased rain and outdated infrastructure has caused many municipality storm sewers and drainage systems to exceed capacity, resulting in flooding and additional expense. To cost-effectively mitigate the problem, municipalities are turning to the use of inlet control ...

  • Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg

    Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain InfraStructure ...

  • What is a storm water filtration?

    Water is the main source of living for human beings on this earth. Water is not only essential for human life but also it is a fundamental natural resource for sustaining of wildlife and environment. It is the main substance for surviving a healthy life. There are many vital resources which contaminate the water and many death implications occur. Due to many natural calamities, the water source ...

  • Structural improvements on hydrodynamic separators: a computational fluid dynamics approach

    Hydrodynamic separators (HDSs) have been used extensively to reduce stormwater pollutants from urbanized areas before entering the receiving water bodies. They primarily remove particulates and associated pollutants using gravity settling. Two types of HDSs with different structural configurations of the inner vortex-inducing components were presented in this study. One configuration consisted ...

  • Preliminary stabilisation of stormwater biofilters and loss of filter material

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ ...

  • Erosion control products: cost effective alternatives for revegetation

    Erosion is any horticulturist’s worst nightmare. From the process of replanting and restoration, to the loss of the most fertile soil, i.e. the topsoil, erosion can have damaging effects on any cultivation. Although erosion is mainly associated with water erosion, wind erosion and tillage are another two forms of erosion. So what are the signs that can help identify erosion early ...

  • Oil Water Separator Maintenance

    Oil water separators (OWS) can be co$tly to maintain, $20,000 or more on average per cleaning and if not properly managed, can be very expensive conduits of pollution. Have you taken steps to minimize the effects and consequences on your operating co$t? When was your facility’s last OWS maintenance ...

  • How Much Could You Save by Avoiding a Consent Decree?

    In 2012, St. Louis, MO (Metropolitan St. Louis Sewer District) set a record for the most expensive sewer consent decree in history at $4.7 BILLION to be spent over the next 23 years. The cause of this consent decree and the cause of most consent decrees are overflow events that allow untreated waste into the nearby lakes, streams, river, or other nature areas. There are typically two types of ...

  • Evaluation of treated sewage reuse potential and membrane-based water reuse technology for the Bangkok Metropolitan area

    Only 3.4% of total water use in the Bangkok Metropolitan area is reused treated sewage. This study anticipates that further treated-sewage reuse in industrial sectors, commercial buildings and public parks, in addition to present in-plant and street cleaning purposes, would increase total water reuse to about 10%. New water reuse technologies using membrane bioreactor (MBR) and microfiltration ...
