Project Description

The Delaware City Wastewater Treatment Plant Headworks project was the first phase of larger project to upgrade the facility and increase capacity. An existing cramped headworks building and undersized static screen were completely replaced while maintaining operation of the facility. The new headworks building was constructed on top of an existing flow equalization tank and houses two (2) 2,100 GPM internally fed rotary drum wedgewire screens which are similar to equipment used at other County facilities. The innovative design of the new headworks building allowed the County to forgo the installation of a new pile foundation on this site which exhibits poor subgrade conditions.
