Cost issues   Costs associated with Solar Aquatics vary greatly from one town to another. Issues such as how much time is spent in the planning process and getting permits approved all the way to construction give varying numbers. It is also important which country the work is being done in. Unfortunately there have not been many Solar Aquatic plants in the United States from which to draw data. A plant working at full efficiency should cost around the same as a traditional wastewater treatment facility. The best figures on prices come from the aforementioned case study in Annapolis County, Nova Scotia. The cost of setting up the plant was around $350,000. Its net capital cost was $4500. Once the plant goes to its full potential the net cost is predicted to go down to $1350.
