Wastewater Reuse Facts

What is Wastewater Reuse?
Water reuse is the process of reclaiming wastewater, through a high degree of specialized treatment, so that it can be used for beneficial purposes, such as landscape irrigation. In Cape May County, up to 300,000 gallons per day of wastewater received at the Cape May County Municipal Utilities Authority’s Seven Mile Beach/Middle Region Wastewater Treatment Plant is treated to tertiary standards and disinfected to meet the requirements established by the New Jersey Department of Environmental Protection (NJDEP). This reclaimed water is then reused rather than being discharged into the Atlantic Ocean

How is Wastewater for Reuse Treated?
In order to protect public health and environmental quality, the NJDEP requires extensive treatment and disinfection of wastewater effluent prior to reuse. The Cape May County Municipal Utilities Authority utilizes a highly engineered system that includes filtration, biological and chemical processes plus chlorination and ultraviolet disinfection to achieve the highest “Public Access” standards established by the NJDEP. The CMCMUA closely monitors this advanced treatment process to ensure that all regulatory requirements are being met.
