The Upper Gwynedd Township, Pennsylvania wastewater treatment plant (WWTP) which treats residential waste (70 percent) and industrial waste (30 percent) was struggling to maintain performance during peak wet weather flows. The facility was designed to treat an average daily flow of 5.7 million gallons per day (MGD) and a maximum monthly flow of 6.5 MGD with a peak hourly flow of 12 MGD.

Since the wastewater treatment facility is located near a retirement community, the design of the plant had to be taken into consideration as well as the small land area, noise level of the equipment and potential odors.

Located between Milwaukee and Madison at the intersection of two Wisconsin interstates, the Village of Johnson Creek is one of the fastest growing communities in the region. It bills itself as the "Crossroads with A Future." Recently, the town had to step up planning for the future as its wastewater treatment plant reached a crossroads of its own.

Located in Kansas City, Missouri, the Blue River Wastewater Treatment Plant (WWTP) was in need of a solution to address high inlet contaminant loadings at multiple locations throughout the plant as well as meet high odor removal efficiency requirements using only biological treatment. The Blue River WWTP is the largest wastewater treatment plant in the metropolitan region treating an average of 75 million gallons per day (MGD).

Columbus, Ohio’s Jackson Pike Wastewater Treatment Plant (WWTP) uses seasonal disinfection. Located in a highly industrial/residential area, the plant has a design treatment capacity of 68 mgd and a peak treatment capacity of 110 mgd.

Saint Petersburg, Florida, is home to about 250,000 residents who enjoy "Florida’s Sunshine City" located on Tampa Bay. The city has one of the largest water reuse programs in the country; it serves residential, commercial and industrial customers via a dual municipal distribution system delivering over 37 million gallons of reclaimed water per day (MGD).

A community lift station in Southwest Florida received complaints from the local residents due to a prominent odor coming from the unventilated wet-well. The municipality reached out to Xylem for a solution.

The WWTP was embarking on a $353 million project to expand treatment capability and replace aging infrastructure before it wore out. The three-year expansion was conducted to keep pace with the growing population, increasing treatment capacity from 28.7 million gallons a day to as much as 45 million gallons a day.

The Georgetown Wastewater Treatment Plant (WWTP) located in Ontario, Canada, provides industrial and municipal wastewater treatment for the urban area in the Town of Georgetown. The plant treats approximately 17.5 ML of wastewater per day.

Avon Lake Water Filtration Plant was built in 1926 to serve the city with the capacity of 2 million gallons per day (mgd), producing water for 1,200 people. The city strives to make their drinking water system among the most progressive in the country. Over time the plant’s treatment processes has evolved to improve drinking water quality. The maximum water production capacity recently increased to meet demand...

The Lincoln Avenue Water Company needed a treatment system for the removal of perchlorate from their primary wells. The company provides 2,000 gpm of drinking water to the community of Altadena, California. Recent water analysis from the wells indicated perchlorate levels above California's Public Health goal of 6 ppb.

California Water Service Company had acquired another water company with approximately 100 connections, in Porterville, California, located in a remote agricultural area of the Central Valley.  Their annual well testing had shown levels of nitrate at or near the Maximum Contamination Level (MCL) of 45 ppm and perchlorate was found in the groundwater at levels above the Public Health Goal (PHG) of 10 ppb. A treatment system was needed to remove both these contaminants to ensure quality potable water for the local community.

Water is the lifeblood of community and industry in the picturesque seacoast towns of Kennebunk, Kennebunkport and Wells, Maine ... where tourism, farming, and commercial fishing help drive the local economy. That’s why, when two prevalent perfluoroalkyl substances (PFAS) — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) — were detected...

In response to changing water quality requirements, the water treatment plant was taking corrective actions to ensure it was producing the best water possible. Excessive algae can clog intake screens, cause pH levels to fluctuate, increase chlorine demand, and negatively affect the taste and smell of water. One of the goals of its latest water improvement project was to reduce algae build-up in its settling basins.

The Moon Township Municipal Authority (MTMA) provides water service to 8,500 water customers in Moon Township; 9,500 sewage customers in Moon, Crescent and South Heights; and wholesale sewage treatment services to three other townships. MTMA originally was a well only water supplier. To meet growing demand raw water from the Ohio River was added in 2003.

After the Environmental Protection Agency (EPA) reduced the Maximum Contaminant Level (MCL) for arsenic presence in drinking water from 50 ppb to 10 ppb. The Pinckney School District sought a solution for treatment of arsenic, tested at 20-25 ppb, and to be compliant with the new requirements.

The City of Fresno, CA was forced to seek a solution to return previously contaminated and closed drinking well sites online in order to answer it's population increases and possible summer drought conditions These wells had been removed from service due to nitrate levels above the State of California maximum contamination level.

Municipalities are often faced with VOC contamination of their source wells. Chemicals like Vinyl Chloride and Trichloroethylene can leach into aquifers used as source water for municipal wells. When this occurs, in many cases the most cost-effective solution is to treat the water to remove the VOCs using air stripping, which has been established as a Best Available Control Technology BACT for this application.

The German municipal waterworks SWU Energy provides 162,000 people per day with potable water. This encompasses a distribution system of approximately 760 kilometres in Ulm, Neu-Ulm and the neighboring districts. More than 11 million cubic metres of water per year come from the valleys of Donau and Iller. The sedimentary nature of the region ensures the high quality of the water which is distributed by twelve pumping stations and ten high-level reservoirs.

The city of Scottsdale, Arizona, a community of more than 200,000 residents was historically totally dependent on groundwater resources. By the mid 1980's, the city began putting together a multi-faceted water resource program to provide the community with a long-term sustainable water supply.

Fraser Coast Regional Council (FCRC), through Wide Bay Water (WBW), a commercialized business unit of the Council, maintains numerous water supply schemes throughout the region, including remote reservoirs. Reservoirs offer security of potable water supply to the community despite seasonal demands. Additional chlorination may be required to ensure the Australian Drinking Water Guidelines are met.
