    Stormwater Wetland Reduces Sewer Overflow By 84 Percent

    Through hydraulic computer modeling, MWH Global helped alleviate stormwater flooding in Cambridge, M.A., by creating the Alewife Reservation Stormwater Wetland to enhance water quality and provide recreational benefits to the community.

  • Installing Hydro-Guard® Automatic Flushing Saves Rural Texas Town $8,000 A Year
    Installing Hydro-Guard® Automatic Flushing Saves Rural Texas Town $8,000 A Year

    Managed by the private, non-profit South Jasper Water Supply, Buna, Texas’ water system contains 91 miles of un-looped distribution pipe with historical water losses of up to 30%. A small operations team is responsible for monitoring two water plants, reading 700 meters, repairing leaks, and flushing water to control the water quality. In an effort to spend less time manually flushing hydrants and focus more time on repairing leaks to reduce non-revenue water loss, South Jasper Water Supply purchased and installed two (2) Hydro-Guard® HG-1 Basic/S Flushing Systems.

  • Field And Office Technologies Improve Stormwater Systems
    Field And Office Technologies Improve Stormwater Systems

    Although the city of Bozeman, Montana’s stormwater system has been silently producing front-page news for decades, it has typically only flowed into the spotlight because of an incident or an emergency.

  • Addressing Chronic Flooding In Texas
    Addressing Chronic Flooding In Texas

    The city of El Paso, TX, lies on the tip of the Chihuahuan desert, and it is not uncommon for a year’s worth of rain to occur in a matter of days during the summer.

  • Hydro-Guard® Improves Water Quality And Saves Man-Hours For Central Texas Vacation Community
    Hydro-Guard® Improves Water Quality And Saves Man-Hours For Central Texas Vacation Community

    The user population of a Central Texas resort system does not reach its peak until summer and the resultant levels of peak and low usage vary widely. This fluctuation impacts levels of disinfectant residual and, consequently, water quality — especially at the end of the line. Manual flushing of the utility's hydrants to maintain water quality has resulted in excessive time and labor as workers must access the outlying areas.

  • Using Technology And Best Business Practices To Make The Best Use Of Resources And Save Public Dollars
    Using Technology And Best Business Practices To Make The Best Use Of Resources And Save Public Dollars

    Creating long-term efficiencies and sustainability is a huge focus of today’s government sector.  Every day the charge of Public Works’ leaders is to do more, with less. Further, technology, if used correctly, can be an effective tool for organizing work and cutting costs. 

  • Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance
    Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance

    The Cincinnati Zoo uses an ultrafiltration system (UF) to treat stormwater. The reclaimed water is collected from 14 acres of the park, including parking lots, animal exhibit yards, rooftop drains, and walking path storm drains

  • Decades-Old Storm Water Problem = Solved
    Decades-Old Storm Water Problem = Solved

    Located 16 miles southeast of Houston, Pasadena, TX, is the second-largest city in Harris County and home to 150,000 residents. Its proximity to the Gulf of Mexico means the city receives nearly 55 inches of rain each year, 17 inches above the state median. Combined with Pasadena’s relatively flat topography and poor drainage systems, heavy rainfall can cause flooding and block major highways.

    The Prince William County Service Authority carefully considers its impact to the environment when conducting wastewater treatment.

Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon

Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

<B>XPSWMM:</b> Complete Stormwater, Sewer and Floodplain Model XPSWMM: Complete Stormwater, Sewer and Floodplain Model

XPSWMM is a fully dynamic hydraulic and hydrologic modelling software that combines 1D calculations for upstream to downstream flow with 2D overland flow calculations so that you can see what truly happens to your stormwater system, foul water system or floodplain when waters flow, populations increase or catastrophic events hit.

<B>XPDRAINAGE:</b> Automate The Sizing Of Traditional Stormwater Systems And BMP Facilities XPDRAINAGE: Automate The Sizing Of Traditional Stormwater Systems And BMP Facilities

XPDRAINAGE is an automated stormwater design software program that provides comprehensive assessment of stormwater designs and is enhanced by "one-click" optimizing for all Runoff Reduction practices.  Unlike many other tools and spreadsheets that assist with facility planning, XPDRAINAGE is integrated with CAD to shorten the design time, whatever your workflow. 

Orenco Sewer Orenco Sewer

Wastewater Collection System

Orenco Sewer™ (effluent-only sewer) is a cost-effective, environmentally sound wastewater collection system. With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land. Solids remain in the underground tank for passive, natural treatment and only need to be pumped every 10 to 12 years (depending on the number of residents and the tank volume).

Orenco Sewers take significantly less time to install than conventional sewers. And in an Orenco Sewer, material and excavation costs are reduced because the inexpensive collection lines are shallowly buried just below the frost line. Because only liquid is being pumped, system designers don’t need to worry about minimum velocities and associated grades. This simpler installation process causes less disruption to communities and allows businesses to operate normally during construction.

StormTEE Litter Control Screens StormTEE Litter Control Screens

StormTEE® litter control screens are ideally suited for the simple, affordable removal of trash/litter/debris and associated pollutants from stormwater flows in a variety of applications. These patented, self-cleaning deflector screens can be used alone or in conjunction with other devices, including the combination fine- particle separation and oil/water coalescing modular unit as part of a complete BioSTORM® stormwater treatment system. StormTEE® deflector screens are easy to install in both new construction projects and is perfect for retrofits too.

Preventing Backflow Preventing Backflow

There are lots of applications in the water and wastewater industry that need backflow prevention. Stormwater drainage systems are a perfect example.  As Mike Duer, Chief Engineer with Red Valve Company explains in this Water Online Radio interview, “water will backflow through the drainage pipe at high tide, come up through the inlets and cause flooding.”

Measuring Flow In A Partially-Filled Pipe Measuring Flow In A Partially-Filled Pipe

Accurate partially-filled pipe measurement is essential when dealing with variable stormwater flows or over-sized community systems built for future growth. In Europe, new stormwater regulations requiring treatment before release are driving a change in measurement that will likely be seen in the U.S. in the not-too-distant future.
