answer to 15, doesn't allow me to specify!-email direct to me from Portsmouth water

If the reservoir is to be used for water sports will this include boats with engines?  I hope not because that would add to the cost of cleaning the water.  Also I'd be interested to know about the increased costs of cleaning this water anyway, as it will have initially come from springs it will start as really clean water then as it sits in the reservoir it will get dirty and that will increase cleaning costs.  If it is to be a wildlife habitat will it also contain fish or will it be chemically treated?
