INTERIM WORK AT QUINCY: The Irving Sealion, a large oil transport barge operated by a subsidiary of Irving Oil

Co. of Canada, is shown in drydock at General Dynamics,

Quincy Shipbuilding Division, for repairs. The barge, emp- tied of all oil before coming to Quincy, is 360 feet long and normally serves the Gulf of St. Lawrence. Shipyard management is continuing to aggressively pursue repair and conversion work, which will provide interim employ- ment for the various trades until the start of construction of liquefied natural gas ships later this year.

Colt Industries Publishes

Informative Bulletin On

Shipboard Sewage System

The ENVIROVAC sewage system for marine applications is described in detail in a new six- page full-color bulletin now available from Colt

Industries' Water and Waste Management Op- eration.

The informative bulletin presents solutions to many existing and future marine sewage collection problems and describes the advantages of the proved ENVIROVAC system. The bulletin in- cludes a schematic diagram showing a typical EN-

VIROVAC installation in a large ferryboat.

Mobile units that can be used for ship con- struction areas are also available.

The ENVIROVAC system is expressly de- signed to save water and overcome the weaknesses of typical shipboard sewage disposal systems. The basic, patented system and ENVIROVAC com- ponents have been proving their worth in ships and on land all over the world since 1959.

The ENVIROVAC concept holds great in- terest for both governmental authorities and ship- owners and operators. Here are a few reasons why.

ENVIROVAC uses air as well as water. And

June 15, 1973 the water that's needed is minimal. Three pints per flushing.

ENVIROVAC can separate black water (toilet waste) from gray water (wash waste) to con- serve storage space on ships, save possible treat- ment costs.

How ENVIROVAC works. The flushing cycle of the ENVIROVAC vacuum toilet takes seven seconds, including water spraying, for cleaning and filling the bowl. Approximately three pints of water are required. And, because air enters the vacuum toilet at each flushing, it also serves to ventilate the area.

The tremendous savings in water are obvious when compared to a conventional household toilet requiring four to six gallons of water for each flushing. Many ships use such toilets.

In the ENVIROVAC system, the black water discharge pipe is held under a constant vacuum of about one-half atmosphere psi) produced by a small vacuum pump. The toilet is connected to the piping, and its valve mechanism is acti- vated when flushing and held open for three sec- onds. This allows atmospheric air to enter the vacuum system. Waste, in the form of a liquid plug, is forced by the air at high speed through piping connected to an approved collecting tank.

The entire system is simple to install, and the small two-inch steel or PVC piping can easily be designed to be compatible with other piping sys- tems on new or older ships. And, because it is a vacuum system, piping can be run up and around bulkheads and obstructions. Roll and pitch doesn't affect the system.
