PROJECT HIGHLIGHTS

Ovivo helps the community provide environmental stewardship of the Delaware Inland Bays with a low nutrient WWTP.

DESCRIPTION

An Enviroquip MBR treatment system was selected to supply low TMDL for both Total Nitrogen and Total Phosphorus. Located in Rehoboth Beach, DE and Delaware’s environmentally sensitive Inland Bays, recommendations of the Delaware Inland Bays Comprehensive Conservation and Management Plan were put into play when a new 180 unit residential development was proposed.   The 4 stage MBR system is performing better than discharge permit levels of TN limits of < 5 mg/L and TP of <1.5 mg/L. Ovivo helps the community with their stewardship of their natural resources and the unique environmental demands of this coastal community.
