For over 40 years, our experts have partnered with the US Army Corps of Engineers (USACE) and the Diamond State Port Corporation (DSPC) to enhance the Port of Wilmington— the heart of Delaware’s blue collar jobs. Specifically, when these groups have needed assistance planning improvements and managing the site, they have consistently turned to our team for support.

Over the years, our staff has provided extensive environmental, civil, geotechnical, marine, and materials testing engineering services for projects including environmental maintenance and larger projects such as a $10 million expansion at Wharf 7, the addition of a $30 million automobile berth in the Delaware river, the design of a multiple dry and conditioned warehouses, container crane staging and support and monitoring and reconstruction on over 150 acres of reclaimed land adjacent to the Delaware River. Here, our rich history of institutional knowledge at the site, enabled the Port to continue its successful work as an economic driver.

Mandated to eliminate wastewater stream discharge for compliance with the Inland Bays Total Maximum Daily Load, The Town of Millsboro embraced an innovative solution based on recycling, rather than disposal, of high quality treated effluent. The recycled water is used to recharge the local aquifer through seven rapid infiltration basins (RIBS).  With a capacity of 1.2 MGD, Millsboro’s RIBs are the largest municipal system in Delaware.  RIB systems require less land and have lower long term operating costs than wastewater disposal systems using irrigation.  Hydrogeological testing has demonstrated that the performance of Millsboro’s RIB system exceeds the original design criteria.

Delaware City faces the threat of flooding from intense rainfall combined with high tidal surge.  Verdantas managed the planning, design, funding acquisition, permitting and construction review of interdependent stormwater system improvements for the City’s flood mitigation project.  The project included replacing and extending an existing stormwater outfall, underground piping conveyance and storage improvements and an 18,000 gpm stormwater pumping station to mitigate chronic flooding.  The City now maintains a robust, automated collection and pumping system to mitigate flooding in its downtown historic area.
