In 2012 when Superstorm Sandy hit the New Jersey coastline, it devastated Route 35, a critical flood evacuation route, just north of Island Beach State Park. With this critical coastal evacuation route severely compromised, the New Jersey Department of Transportation (NJDOT) took immediate steps to restore safe travel.
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.
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.
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.
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.
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.
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.
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
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.
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.
Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.
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 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.
As a Sustainable Drainage System (SuDS), the d-Rain Joint™ is a simple, low-cost, and robust onsite storm water management alternative compared to other permeable, pervious surface options and can be used wherever a permeable, pervious driveway, parking lot, street or walkway is needed. The use of traditional pavement with the d-Rain Joint™ provides both permeability AND filtration at a lower installed cost!
The WWETCO FlexFilter™ from WesTech uses compressible media to provide an efficient new solution for CSO, Primary Treatment, Tertiary Treatment and Industrial Water Pretreatment. The FlexFilter™ is a simple gravity system with a robust design requiring no moving parts. The combination of tapered media compression, porosity gradient within the media bed and a low flow backwash system make the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.
Designed to increase chlorine residual consistency in potable water systems, Mueller® has added the HG-8 model to the expanding line of Hydro-Guard® Automatic Flushing Systems. Hydro-Guard HG-8 is installed below the frost-line, with all components easily accessible from the ground surface in the Mueller Thermal-Coil® Box. Dechlorinated discharge water is directed to the storm water drainage system or local retention pond. In addition, the product is designed to accept a 1-inch meter.
The 5000s model of pH control systems from Fortrans features a full size utility building with lockable steel door, lights and shelving. The 5000s offers similar process water and stormwater treatment capabilities as the 5000b system.
Automate the sizing of sustainable stormwater systems and clearly visualize your design.
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.”
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.
