The 55.5-million-gal-per-day (mgd) Southern Regional Wastewater Treatment Plant (SRWWTP) in Hollywood, Fla., treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 mgd of additional reuse water on an annual basis.
In 2016, Hillsborough County Public Utilities initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100% of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges.
The Hudson River, in the Capital District of Albany, N.Y., is a popular recreational area for boating, swimming and fishing. Unfortunately, combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800s were causing increased fecal coliform counts, which, in turn, resulted in health alerts and limited access to the river.
Xylem, a global water technology company, announced that its Wedeco brand—which focuses on chemical-free, sustainable water treatment technologies—is this year celebrating its 40th anniversary. There are more than 250,000 Wedeco ultraviolet (UV) disinfection and ozone oxidation systems operating worldwide in private, public utility and industrial applications.
Xylem has been awarded a $1.3 million contract to provide advanced treatment technology to the Saigon Water Corporation’s Tan Hiep Water Treatment Plant 2 in Vietnam’s capital, Ho Chi Minh City. Under the contract, Xylem will design, install and commission an expansion of the existing treatment plant, to include the first ozone treatment application in Vietnam. The upgrade will increase the plant’s productivity, enabling it to produce 300,000 cu m of drinking water per day, benefitting 1.5 million Ho Chi Minh City inhabitants, or 15% of the city’s population.
The Georgia Aquarium, located in the heart of Atlanta, opened its doors in 2005 as the world’s largest aquarium, with 100,000 freshwater and saltwater aquatic residents in 10 million gal of water.

The communities serviced by the Rensselaer County Sewer District, collectively known as the Albany Pool, have combined sewer systems (CSS) that bring storm water, sewage and industrial wastewater directly to the wastewater treatment facility. When a storm or snowmelt results in exceeded capacity, local waterways become contaminated, resulting in a significant environmental challenge—especially in a community where recreational swimming, boating and fishing are popular in warmer months.
The American Canyon (Calif.) Wastewater Treatment Plant (WWTP) began operation in October 2002 with then-state-of-the-art secondary treatment that featured one of the nation’s first uses of tandem membrane bioreactor/UV disinfection in the process chain. As with many other early membrane bioreactor treatment plants, this facility had a number of design deficiencies, which became apparent over time as the equipment aged, the utility’s customer base expanded and more stringent environmental regulations were enacted.
A $250 million capital program by the Metropolitan Water District of Salt Lake & Sandy (MWDSLS) has equipped the wholesale water utility to produce improved water quality and to meet projected demand through and beyond 2025.
By 2025, Salt Lake City expects to gain additional 100,000 residents, and the City of Sandy expects to gain 30,000. The accelerating growth of the MWDSLS customer agencies, along with the need for system reliability and redundancy, spurred the proactive capital improvements.
Located north of Phoenix, Lake Pleasant Regional Park serves as a large outdoor recreational hub for Arizona residents. The lake itself, the second largest reservoir in Arizona, is a place where people boat and swim, and it serves as a water resource for the 400,000 households within the municipal boundaries of Peoria.
The Rio Grande River and the two major aquifers in the El Paso, Texas, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant—the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.

SNIACE’s cellulose is used to make various products, such as viscose fibers for the textile industry; acetate for the chemical industry; sanitary towels, insulators and cellulose film for industrial applications; and cloths and sponges for household use.
With diminished rainfall, a depleted aquifer basin, near-empty recharge ponds and an earthquake-vulnerable aqueduct system, the Santa Clara Valley Water District (SCVWD) in San Jose, Calif., required additional water supplies to maintain regional economic vitality for its growing community.
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant and Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public. Ozonation has helped prepare a North Carolina Water Treatment Plant (WTP) to comply with these federal drinking water regulations and overcome long-standing taste and odor problems of its raw water drawn from the B.
Clovis is a city with a population of around 97,000 in Fresno County, Calif. The city is 6.5 miles northeast of downtown Fresno. Until the early 1970s, groundwater was the sole water source for the residents of Clovis. Well water was used for irrigation and industrial use, as well as drinking water. As the population grew in Fresno County, ground water levels dropped and wells began drying up. To meet the growing water needs, the city of Fresno decided to recycle water being processed at its wastewater treatment facilities.
The city of Carmel, Ind., located north of Indianapolis, owns and operates Carmel Wastewater Treatment Plant (WWTP), which treats sanitary waste from Carmel, Clay Waste District and Westfield Utilities. When the plant became unable to meet the growing demands of the 70,000-person population area, the city decided to increase Carmel WWTP’s capacity to meet current and future water treatment demands.
Prairie du Sac, a village of 3,400 located in south central Wisconsin, began its journey to UV disinfection when it was selected as one of 14 communities in the state to participate in a $2.3-million, U.S. Environmental Protection Agency (EPA)-funded study focusing on the role of drinking water in childhood illnesses. The Marshfield Clinic Research Foundation in Marshfield, Wisc., conducted the Wisconsin Water and Health Trial for Enteric Risk.
