Bio-diversity in Florida’s St. John’s River estuaries is dependent on clean water. Growth in the area’s coastal communities is adding nitrogen and phosphorous nutrients to the river through wastewater discharges.

The South Dearborn Regional Sewer District in Lawrenceburg, Indiana, provides regional wastewater treatment services for three cities and an international distillery. The 6 mgd treatment plant is located in an area of high population growth and is surrounded by many retail operations and other commercial developments.

Located in the Shenango Valley watershed of western Pennsylvania, the City of Hermitage's aging infrastructure began to collide with its growing treatment needs. Hermitage also undergoes heavy summer thunderstorms when wastewater volume can double or triple in a couple of hours.

Constructed in the 1980s, the A.J. Brown plant is the largest of three wastewater plants in the city of Huntsville. This upgrade will expand capacity, improve energy efficiency and better handle peak wet weather flows in a small footprint. 

Xylem has announced that it has been selected by Payson City, Utah, to expand the City’s wastewater treatment plant. The plant expansion will address the needs of this growing community as well as meet current and future nutrient removal requirements.

Nutrient removal is an important process in meeting high quality effluent requirements. Excessive levels of nitrogen and phosphorous disrupt the natural environment and can affect the health of water systems. Furthermore, Prattville's wastewater system was projected to reach its capacity as the population of the surrounding area grew.

Key West is one of America’s most scenic locales. Situated in the Florida Keys southwest of Miami, it is visited by millions of people each year and is home to more than 30,000 year-round residents. While there’s plenty of ocean, potable water is a precious commodity which is piped 125 miles from the mainland.

Evoqua Water Technologies LLC was contacted by a South Florida Municipality to provide an odor control solution for a lift station within their collection system. In the past, the municipality had implemented biofiltration for control of atmospheric hydrogen sulfide. However, in recent years the biofilter was removed, leaving the lift station untreated and exposed to high sulfide concentrations.
