Two of the options, Options 6 and 7, are based on maintaining full secondary treatment at the Blackbum WWTP site. These two options have been further subdivided into Options 6a and 6b, and 7a and 7b, respectively, to address the issue of ammonia toxicity removal. Conceptual level costing has been developed for each of the options as well as detailed
