In 1999, NSU acquired the community’s existing wastewater facility, a system designed for the 1,200-residence community for adults 55 and older. The community is located on a 295-acre site surrounded by sprawling grounds and the facility is permitted to discharge 250,000 gpd to the Assiscunk Creek, a NJ DEP designated Category 1 waterway in the State. The designation means that the waterway is of significant environmental importance to the watershed and to the wildlife depending on it for sustenance and therefore, extra care must be taken during the discharge stage of the treatment process.
Over the next six years NSU conducted a series of upgrades developed in conjunction with the New Jersey Department of Environmental Protection and aided by a grant from the New Jersey 1981 Water Supply State Bond Fund. The most recent upgrades made to the wastewater treatment system enable the delivery of high-quality recycled water that will be used to maintain the residential grounds as well as achieve multiple state goals related to Smart Growth.
NSU provides overall O&M services at the Mansfield treatment plant. The wastewater treatment process consists of two large partial mix aerated lagoons followed by a Lamella plate settling unit sand filtration, break point chlorination, dechlorination, and post aeration prior to discharge to surface water.
