The water management systems, Aquarius Plus Gvii DF (DIRECT FLOW,) Aquarius Plus Gvii and Aquarius

Plus Gvii Kitchen, we are pleased to submit hereby below our proposal along with additional information.

  1. Summary

Our systems treats the water just before entering the glass or the cooking equipment removing the

harmful contaminants and sediments that, based on our experience, are present in most vessel’s water

networks (i.e. tanks and piping). In addition our systems provide a sufficient solution to the unwanted situation of the usually unattended shipment of bottled water, which doesn’t ensure the correct transportation conditions indicated in bottled water labels (i.e. store / transport the bottle in dry and cool place below 18°C, out of direct sunlight and away from toxic chemicals).

Installing Aquarius Plus systems onboard assist company to move towards to more environmental friendly

practices by removing a large amount of plastic bottles from the environment and the relevant power

consumption necessary for the production. For example with 25 persons crew x 2 bottles (1,5lt) per day/person x365 days = 18.250 bottles/year. Our resent research, getting the prices from a number of ports (Piraeus, Brazil/Santos, Canada/Vancouver, Panama, Chile and China, we calculate that the estimate average price for 1,5 lt bottle is 0,395 EURO. For realistic analysis of the current costs of potable water supply you should include the additional costs related with the transportation of the bottled water onboard (i.e. cost for barges and trucks), the storage and the waste management (i.e. cost for plastic bottle handling with compactors, trash bags and waste
