<br />Comprehensive Sanitary Sewer Plan <br />City of Arden Hills, MN <br />WSB Project No. 3455-20 Page 9 <br />Wastewater Flows <br />All of the wastewater flow from the City of Arden Hills is treated at the Metropolitan WWTP, and <br />any increase in wastewater flow will be treated at the Metropolitan WWTP as well. Table 5 lists <br />the projected total average wastewater flow for Arden Hills from MCES and from this Sanitary <br />Sewer Plan. Note that the projections used in this report are greater than the MCES projections <br />since they rely on flow estimates for each parcel of developable land. <br />Table 5.
