JACKSONVILLE, Fla. (NNS) -- Naval Facilities Engineering Command Southeast awarded a nearly $18 million contract April 11, to CDM Constructors, Inc., out of Maitland, Florida, for repairs of a water distribution system at Naval Air Station Joint Reserve Base New Orleans.

"The water distribution system on NAS JRB (Naval Air Station Joint Reserve Base) New Orleans supplies the domestic and fire protection needs of more than 190 facilities spread across the 3,351 acre installation," said NAS JRB New Orleans Public Works Officer Lt. Cmdr. Micah Kiletico. "Much of the distribution system is over 50 years old, and because the potable and fire suppression systems are combined, it is extremely inefficient and costly to maintain."

The fire suppression requirements of the aircraft hangars located on the flight line require a water distribution system capable of supplying a very high pressure and large flow. The pipe sizing and water storage requirements for this component greatly exceeds the normal base domestic water demand and creates an excess of stored water in the system that must be treated.

"Separating the hangar fire suppression requirements from the potable water distribution system will decrease the volume of potable water in the system to what the base can reasonably consume within the regulatory limits and reduce waste," explained Kiletico.

The repair will consist of analysis, field investigation, solution development, computer modeling, permitting, design, construction and testing of the water system to ensure the domestic water system meets all federal, state, and local regulatory requirements.

Key components of the project include the repairs and isolation of the existing 1 million gallon water tank from the potable water distribution system, reconfiguration of the water service connection to supply both potable and non-potable systems, repairing the existing water pump and line to service the existing 500,000 gallon water tower, replacing the chlorine injection at the discharge site from the existing water tower, replacing the water main distribution piping and reconfiguring recirculation lines to meet water quality requirements with no new capacity. The fire suppression water distribution system for the aircraft hangars will be isolated and pumps and supporting equipment will be replaced.

Work is expected to be completed by September 2017.
