STORMWATER MANAGEMENT CASE STUDIES AND WHITE PAPERS
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
Wastewater Plant Taking Proactive Measures To Protect Natural Resources
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
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.
Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling
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.
Submersible Pumps Eliminate Flood Damage Concerns At LaGuardia Airport
During Hurricane Sandy, La Guardia Airport’s five stormwater pump stations lost power, resulting in flooding of an estimated 100 million gallons of water. The Port Authority of New York & New Jersey quickly moved up its planned renovations and installed nine axial flow pumps capable of moving large volumes of water at low heads. The propeller-type pumps have motors that are invulnerable to submersion during high-water incidents, improving the airport’s stormwater control, flexibility, and operational efficiency.
Flood Improvement And LID Modeling Using XP‐SWMM
Over the years, a number of severe storms have impacted the Harris Gully watershed, including Tropical Storm Allison, which resulted in $5 billion in damages in 2001. Inundation was especially severe at the downstream portions of Harris Gully, where Rice University and the Texas Medical Center are located. A1D/2D hydraulic model (XPSWMM) was instrumental in simulating and evaluating the effects of a proposed drainage alternative.

Membrane Filtration Water Treatment Plant Meets Hotel Complex's Needs
The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.
Stormwater Treatment and Reuse - Toronto, Ontario (Case Study)
Sherbourne Common is an innovative waterfront park that provides the public with green recreational space along Lake Ontario in a former industrial area.
Asset Inspections Are Optimal Tool For Maintenance And Capital Improvement
Infrastructure asset inspection process is a tool that identifies deficiencies, creates backlog, establishes proactive maintenance, and monitors life cycles; as well as assists agencies in identifying projects for their Capital Improvement Program (CIP). These inspections can provide both a short-term benefit through work identification for repair and maintenance efforts and a long-term benefit of project identification of new capital improvements and enhancement.
