The plant currently <br />serves the cities of Anoka and Champlin. In about 1985, it <br />is projected that a portion of Ramsey will be sewered. Based <br />on current flow projections for Anoka and Champlin, the <br />existing plant will become hydraulically overloaded in 1984. <br />The existing site is limited as to future expansion but could <br />accommodate approximately a doubling in size, which will be <br />adequate for the remainder of the century. <br /> <br />Sludge processing is currently accomplished by anaerobic <br />digestion. <br /> <br />Sludge is disposed of by either hauling to the Metropolitan <br />Plant interceptor system or land spreading. Currently, the. <br />MWCC .is examining'ultimate disposal' of sludge from each of <br />its treatment plants. However, no recommendations regarding <br />the future handling of sludge have been made for the Anoka <br />facility. <br /> <br />The current interceptor river crossing from Champlin to Anoka <br />is not adequate to serve the entire population of Chs3nplin. <br />Documented cases of on-site systems failures in central and <br /> <br />* WWTP = Wastewater Treatment Plant. <br /> <br /> <br />
