When Hurricane Floyd hit New Jersey in 1999, the Raritan River overflowed its banks and caused extensive flooding at the 150-mgd Raritan-Millstone water treatment plant, shutting down service to the plant's 500,000 users and requiring a regulatory boil water advisory to citizens. CDM mobilized immediately to help the water company get the plant back online, bringing process, mechanical, and instrumentation and control specialists to assess the damage and return 12 of the plant's filters to service. The water company's personnel and CDM staff worked 24 hours a day, over six days to stabilize the plant and rescind the boil water advisory.
The CDM emergency response team restored the sand filters, rebuilt 24 valve actuators, and fabricated and installed 12 new filter control consoles. Using a design-build approach to expedite the procurement of critical equipment, CDM designers, construction crews, operators, and subcontractors worked together to coordinate repairs. CDM rebuilt the damaged actuators onsite in 2 weeks, 4 weeks ahead of the earliest possible fabrication and delivery of new actuators, in order to return the filters to operation at the earliest possible time.
