The inaugural New Jersey One Water Awards, sponsored jointly by Jersey Water Works, the Association of Environmental Authorities of New Jersey, and the New Jersey chapter of the American Water Works Association, have been awarded to four projects that highlight innovative best practices in management across the full water cycle. The awards were developed to honor initiatives that exemplify the principles of the One Water approach: the belief that all water- stormwater, drinking water, wastewater- has value that can be unlocked by implementing sustainable, inclusive, and integrated water resource management practices.
“It was terrific to see so many innovative things happening in New Jersey that are using the One Water approach to upgrading our water infrastructure,” said Jennifer Brunton, director of environmental services at Louis Berger, a member of the Jersey Water Works Steering Committee and the chairwoman of the One Water Awards jury. “We hope these first awards will shine a spotlight on initiatives that exemplify integration across the water cycle and with other community priorities, reflect collaboration, employ innovation and education, and advance long-term sustainability. We want these winners to serve as an example so that we can encourage more such innovation.”
“We were extremely impressed with the quality and thoughtfulness of the entries,” said Peggy Gallos, the executive director of the Association of Environmental Authorities of New Jersey, who served as a juror for the contest and whose organization is one of the awards programs’ co-sponsors. “It’s clear that people across the water sector are thinking more innovatively and more holistically than ever before about how to treat water at every stage of its cycle as the precious resource it is. That can only bring benefit to the residents and businesses of New Jersey.”
“In addition to these being outstanding examples that any municipality or utility can emulate, these winning projects had one more thing in common that made them successful: significant efforts at public outreach and education,” said Nicole Wiley, who also served as a juror and who chairs the New Jersey section of the American Water Works Association, another co-sponsor of the awards program. “We all know water infrastructure is invisible until it breaks. Whether with tours or interpretive signage or direct communication with stakeholders, those who led these projects all worked hard to be sure the work was visible and its value understood by those who will benefit from it.”
Jurors are asked to recuse themselves from deliberation of any entry that presents a conflict of interest.
Protecting against floods with a community-designed park
The southwest corner of Hoboken has long struggled with flooding–a chronic problem that came into sharp focus during Hurricane Sandy. The area sits on a former marsh that had been filled in and paved, making it vulnerable even to small storms. In response to a grassroots civic movement to address flooding and a lack of green space, the City of Hoboken developed Southwest Park, New Jersey’s first resiliency park.
The city purchased an underutilized parking lot and hired Starr Whitehouse Landscape Architects and Planners to design the park. Over the course of three public workshops, the city gathered input from residents to determine community priorities. Residents evaluated programming concepts and provided suggestions. The final design plan was presented to the community and received popular approval. The completed park, which opened on Sept. 22, 2017, features rain gardens, wood deck paths, a granite amphitheater, a dog run, tables and chairs, a bike sharing station, public WiFi, a central plaza, restrooms, and a perimeter pedestrian mall that can accommodate local vendors and food trucks.
Three stormwater management systems capture stormwater: open-jointed pavers, rain gardens, and vegetated bioswales. The park’s urban plaza area makes use of open-jointed pavers to create a paved area that is completely permeable. It sits on a bed of gravel that filters stormwater before it returns to the watershed. The rain gardens feature native plants and sandy soil to filter water. Excess water flows into one of three stormwater detention basins that are located underground. The bioswales capture water from adjacent roadways and sidewalks, filtering pollutants and directing excess water to the stormwater detention basins.
The three stormwater detention basins capture excess water during heavy storms, with the capacity to hold up to 71,000 gallons. After a storm, the detained water is released gradually into the combined sewer by a sensor that controls the rate of flow. With the stormwater detention basins and stormwater management systems combined, the park can store up to 190,000 gallons in total–enough to provide flood relief beyond the boundary of the park.
Taking advantage of the park’s public-facing nature, the City of Hoboken has installed informational signs to educate the public about stormwater management and environmental issues. The park functions simultaneously as a stormwater mitigation system, public space, and an educational tool.

Sewerage facility with a vision
The Landis Sewerage Authority is a lot more than just a wastewater treatment plant. Its facility-wide programs handle water holistically, with the overarching goal of contributing to the health of the watershed. The result is a plant that operates more broadly as a resource reclamation facility, acting as a positive player within the larger ecosystem.
The authority’s projects begin with water. Each year, the plant returns 1.8 billion gallons — the highest volume in New Jersey — of highly treated effluent to the ground. This strategy differs from most treatment plants, which usually release treated wastewater into rivers or the ocean, preventing a return to the original source. In contrast, LSA’s policy of applying the effluent to land via infiltration basins and spray irrigation helps recharge the aquifer. In turn, the aquifer supports the wetlands and base flow for the Maurice River.
At the LSA, even byproducts have a use. The authority collects wastewater biosolids, which are rich in nitrogen and phosphorus, and uses them as organic fertilizer for the corn, hay, and straw grown on its 400-acre farm. Crop production has exceeded 1,100 tons per year, and gross sales of more than $100,000 per year help stabilize LSA’s user rates. Biosolids are also used for fertilizer as part of LSA’s forest management plan: It used 150 of its 1,800 acres to plant 75,000 trees, including Eastern white cedar. The trees sequester carbon, removing greenhouse gases from the atmosphere.
Landis Sewerage Authority strives to provide habitats for the species that rely on its ecologically sensitive tract of land. Its efforts to maintain the watershed have contributed to a large, on-site population of swamp pink, an at-risk species that is rare elsewhere. In partnership with New Jersey Audubon, the National Wild Turkey Federation, New Jersey Fish and Game, New Jersey Forest Fire Fighting Service, New Jersey Outdoor Alliance, and South Jersey Quail Project, LSA has worked on habitat restoration project for bobwhite quails. The restored pine savannah habitat will also support other bird species and milkweed for Monarch butterflies. With Citizens United of Maurice River, LSA has created nesting boxes for bluebirds. Future projects include a focus on purple martin colonies and continuing conservation collaborations.
On the renewable energy front, LSA hosts solar power in partnership with the Vineland Municipal Electric Utility. A waste receiving station collects food waste, fats, oils, and grease and processes them with an anaerobic digester. The digestion process produces methane, which is then run through a clean-burning engine to produce electricity and hot water. The authority also has an on-site wind turbine mounted on a 45-foot monopole. In 2017, the facility installed two electric car-charging stations that can charge cars using energy from the wind turbine on windy days. On the whole, LSA generates more energy than it consumes.
The authority also recognizes the importance of getting the public excited about environmental efforts. It provides opportunities for various children’s groups, including Poultry Pride, N.J. Youth Corps, and 4H, to participate in habitat restoration. It has sponsored a middle school Earth Day poster contest in Vineland for the past 23 years; approximately 200 students participate each year. For college students, LSA hosts internship opportunities that provide real-world experience working at the facility. Its frequent plant tours reached an international audience in 2016, when the facility hosted several visitors from Africa through the Rutgers Mandela Washington Fellowship for Young African Leaders.

From emergency to opportunity
In December 2016, Middlesex Water Company detected a leak in a transmission main under Route 1 in Edison Township. The leak presented a major challenge. It had to be fixed immediately; the main represented a critical piece of the company’s infrastructure, which serves 61,000 customers in eastern Middlesex County. But its particular location — next to Route 1 and near the Route 287 northbound ramp — created an unusual level of difficulty. A conventional solution would have called for what’s known as open-cut replacement, which would require shutting down two important thoroughfares and excavating the roadway.
Middlesex Water opted for a more innovative strategy: using a carbon fiber-reinforced polymer (CFRP) to repair the 385 linear feet of pipe. The 30-inch diameter of the prestressed concrete cylinder pipe was large enough for an experienced crew to crawl inside and apply the polymer sheet internally. After hardening, the sheet formed a thin liner that left the internal diameter of the pipe virtually unchanged. This structural rehabilitation extended the main’s integrity for a minimum of 50 years of potable water use. The pipe regained its original hydrostatic pressure capacity and gained load capacity. The repair also allowed the pipe to accommodate increased internal pressure requirements. Most importantly, the project was completed rapidly, with no public disruptions or traffic delays. It was the first time that CFRP had been applied to a pipe section of this diameter and length.
While the transmission main was out of service, Middlesex Water undertook an additional proactive step: an internal electromagnetic and CCTV inspection of the pipe to identify any other areas that might need repair. This structural evaluation and assessment provided information about the horizontal and vertical alignment of the main. The electromagnetic inspection revealed that one pipe segment needed imminent replacement. This section of pipe was replaced prior to the CRFP application. By conducting this additional investigation of the pipe before the CFRP process, Middlesex Water ensured that the completed repair was both comprehensive and sustainable.
Throughout the repair process, Middlesex Water consulted with local police, fire, and township officials. The company also collaborated with local businesses, the local gas utility, contractors, consultants, the New Jersey Department of Transportation, and the New Jersey Department of Environmental Protection. Once the project was complete, Middlesex Water informed the public of the repair through social media, demonstrating how proactive infrastructure replacement benefits the community. The company also hosted an information session to share its process with other utilities, construction companies, and engineering firms, and will present a paper about the project at several upcoming industry conferences.

Finding a natural wastewater solution
Stony Brook-Millstone Watershed Association needed a wastewater treatment system—and not just any system, but one that aligned with its mission of keeping water clean, safe, and healthy. Septic systems serving the various structures at the Watershed Center in Pennington had failed. Moreover, SBMWA planned to expand its facilities. Partnering with Natural Systems Utilities, SBMWA developed a holistic, natural solution: a constructed wetland that would function as a wastewater treatment system.
Because the Watershed Center’s combined facilities had to handle more than 2,000 gallons per day, NSU applied for and received discharge to groundwater and treatment works approval permits from the New Jersey Department of Environmental Protection. Once the permits were granted, NSU constructed the wetland in 2014. It commenced operations in 2015 and has achieved a high level of performance since then.
The constructed wetland is a natural, low-energy system that produces a high-quality effluent. Nitrogen is removed prior to groundwater recharge. The system also serves as a landscape that increases wildlife habitat and supports biodiversity. The wetland wastewater project is the ideal complement to the LEED Platinum-certified building that serves as the home of the Watershed Center.
As part of an educational center that has had more than 50,000 visitors since its opening in 2015, the wetland wastewater system provides the public with a strong example of holistic, sustainable water treatment. The watershed association has capitalized on the educational opportunities by installing informative signage and a walking audio tour with QR codes for mobile access. Additional signage in restrooms helps visitors understand the connection between wastewater and the wetland outdoors. The watershed also works with nearby municipalities that are interested initiating similar projects.
