Data Analysis of City of Roseville Recyclable Materials <br />Table 11 <br />Comparison of Bi-Weekly Single Stream and Dual Stream Routes <br />Total Quantities Collected by Route During Pilot <br />(September and October) <br />Total Quantities Collected by Route <br /> <br /> <br />Route 4 Single Stream <br />Routes <br />(Monday) <br /> <br />Route 6 Dual. Stream <br />Routes <br />(Wed -Friday)' <br />Sept. Mon 10,365 Sept Wed 9,625 <br />Sept.
