    The rule for RV self-containment is that the liquid volume of one litre per day per person for a minimum of three days is required. The GTG Bottle offers eight litres of self-containment totalling 4 days for 2 people. Additional bottles offer an extended capacity if the full bottle is kept on board in a suable vented locker until a dump station is available to empty them. Please speak to your SC (self-containment) officer for a final say on the matter.
