- 4 - Alternatives ~a~oka, Chamulin, RamseY Several alternatives for Anoka exist which are 1) build a new facility 1 mile upstream; 2)phase out the plant by an interceptor to't_he M~tropolitan Plant; 3) phase out t~he ~lantby an interceptor to a new plant in Fridley; and 4) total land disposal. Each of these alternatives include th~ Chm/nplin and Ramsey flows being treated at Anoka and the Brooklyn Park flow being treated at the Metropolitan Plant. Another opt. ion which was not costed is for the flows from t_he northern portion of Bro'oklyn Park, north of 85th Street, to go back to the Anoka plant. This was not considered since capaoity in the existing interceptor system is adequate to handle all of Brooklyn Park's flows to the end of the planning period. At some point after 2000 it is anticipated that the flows from the Elm Creek Watershed may be routed through nor%hern Brooklyn Park and then south to the existing interceptor system if the population in this area would warrant sewer service.. Alternative 1 has a presen~ worth trea~ent cost of $5,256,000 and a 9resent worth inter- ceptor cost of $2,023,000. Alternative 2 has a present worth treatment cost at Anoka of $740,000, an interceptor cost to of $8,617,000 and a treatment cost at the Metropolitan Plant/tertia~f levels of $762,000. Alternative 3 has a present worth trea~u~ent cost at Anoka of $740,000, an interceptor cost of $8,617,000, a treatment cost at Fridley to secondary levels of $1,628,000 and an outfall cost of $9,033,000. Alternative 4 has a total present worth cost of $20,139,000 or $9,156,000 depending on the type of land disposal chosen. See land disposal plan for further details. The present worth interceptor cost is approximately $2,023,000. Each of these alternatives is consistent with the Development Fr~ework plan. Evaluation Several items musk be considered further namely local costs to Champlin and Brooklyn Park for local lines. The present wor~h cost for Brooklyn Park to build a local trunk line to its aorthern border is $4,163,000 for Cha~plin to build a line from its southern border to the Anoka plant is approximately $1,744,000~ This is only needed for Alternatives 1 and 4 ~nd assumes that the ~n~ire system ~s buil~.in, i985 and net ~t~d.
