CRW performed a geotechnical investigation to support CRW’s design for a replacement water main on the island and causeway. The investigation included drilling 12 boreholes and performing laboratory testing on acquired samples. The subsurface information allowed assessment of burying the new water mains deeper for better freezing protection and included recommendations for pavement structural sections, drainage, and utility trench construction. The new water main will improve the terminal’s water system reliability, deliver potable water service, and fire protection to the area, and minimize the system’s operations and maintenance requirements.
