A ten inch sanhary sewer will be extended as a part of this project northward along Xkimo Street N.W. beyond the paved intersection of 143rd Avenue N.W. and Xkimo Street N.W. An eight inch sanitary sewer main with four inch service taps for 11 residential lots will be extended down 143rd Avenue N.W. east of Xkimo Street N.W.
