Ramsey Second Interceptor NCC 83-62 <br />EAW - May, 1984 <br /> <br />The length of the interceptor to be constructed by the Metropolitan Waste <br />Control Co~u,~ission (M~CC) is .6 miles or approximately 3200 feet. The total <br />length Of the 33" diameter trunk sewer to be installed by the City of Ramsey <br />is approximately 1540 feet. In addition, 1430 feet of 12" diameter subtrunk <br />and 4000 feet of 8" lateral sewer will be constructed in Ramsey, in the <br />proposed Flintwood Hills Second Addition subdivision. The depth of the <br />trench excavation in which the Ramsey Second Interceptor will be installed <br />will vary between 25 and 35 feet, with a consequent excavation width of 50 <br />to 70 feet. The Ramsey 33" trunk sewer will be 20-24 feet deep, requiring <br />excavation widths of 40 to 50 feet. The sub-trunk sewer will be installed <br />at a depth of 15-20 feet, with trench widths of 30-40 feet, and the sewer <br />laterals will be installed at depths of 10-15 feet, in trenches 20-30 feet <br />in width. Both the 33" trunk and the 12" sub-trunk will eventually be ex- <br />tended to other areas within the Rum River watershed in Ramsey (see item 22). <br />The routes of all sewers laterals and trunks will eventually be paved roads. <br /> <br /> <br />
