Envirovac Receives

Contract To Equip

Twelve U.S.C.G. Cutters

Envirovac Systems, Rockford, 111., was recently awarded an initial con- tract to begin the renovation of toi- let systems on 12 high-endurance cutters as part of a major rehabilita- tion and modernization project by the U.S. Coast Guard. Todd Pacific

Shipyards Corporation, Seattle,

Wash., who will handle eight of the cutters on the West Coast, and Bath

Iron Works, Bath, Maine, who will handle four cutters on the East

Coast, are both involved in the proj- ect.

At present, five of the 12 vessels are equipped with the Envirovac vacuum toilet system. On the ships now containing Envirovac equip- ment, the toilet system will be up- graded; mechanical equipment will be refurbished, 30 toilets will be replaced and 10 toilets added, and the control system modified to in- clude two new features. On those ships containing other equipment, the toilet system will be redesigned according to Envirovac specifica- tions and replaced with Envirovac equipment.

The work is scheduled to begin this month and extend over a period of three years.
