Why use a freshwater depot? 

Sea lice do not like fresh water and stay below the freshwater layer that spring flood creates in the fjords. Use of freshwater bathing treatments have given good results. The challenge has been capacity of well boats and access to sufficient amounts of fresh water. 

When it comes to the use of fresh water to treat fish against AGD it is at least as effective as hydrogen peroxide. The advantage of fresh water is that it is gentler for both the fish and the environment. 

With a freshwater depot you can save time and money. A well boat will use 1.5 hours to fill 1800 m³ from the depot. It is enough water in one O=120m depot to fill three wellboats with 1800 m³. The wellboat will spend 4-6 hours to fill directly from a freshwater source.
