ENVE01 has been tasked with redesigning the on-site wastewater treatment system at Rocky Neck State Park, to preserve the environmental integrity of the site. The park is over 700 acres in size, featuring campsites with a capacity of nearly 1,000 campers, as well as a recreational beach area. There are 7 bathhouses throughout the site, used by campers and beachgoers. During the peak summer season, the park sees a flow of 25,000 gallons per day. The current septic systems on the site are over 50 years old, and many of them have experienced failures. Bride Brook, the stream that runs through the 82 acres of biodiverse and environmentally protective marsh on the site, is seeing elevated levels of nitrogen, phosphorus, and pathogens, threatening the critical ecosystem. The septic systems on the site are likely a source contributing to this contamination. ENVE01 plans to tackle the septic system issues faced by Rock Neck by integrating pretreatment systems, redesigning and replacing faulty system elements, and optimizing the treatment process.
