EXECUTIVE SUMMARY <br />A. GENERAL <br />The purpose for this study is to update the City's comprehensive sewer plans taking into <br />account current population and land use projections. This study incorporates the key components <br />of past studies into one working document for future sewer planning. <br />As with past studies this study does not propose the expansion of sanitary sewers. The <br />purpose of this report is to identify ultimate sewer flows based on current land use planning and <br />identify the approximate location, sizing, and capacity of the trunk facilities needed to serve the <br />potential growth. <br />B. SANITARY SEWER FLOW PROJECTIONS <br />The design criteria used for this report are similar to the criteria used in past reports, <br />however, based on current planning efforts the number of people per unit has been changed from <br />past studies from 3.2 to 3.0 people per unit. Table ES.1 shows the design criteria used for the <br />preparation of this report. <br />Table ES.1 <br />Design Criteria <br />Descripiton <br />Factor <br />Gallon per Person per Day <br />75.0 <br />Flow Variation Factor <br />2.5 to 4.0 <br />People per Unit <br />3.0 <br />Flow per Unit <br />225 <br />Commercial / Industrial Flow per Acre <br />1,500 <br />City of Ramsey Page ES -1 <br />Comprehensive Sanitary Sewer Plan - 2004 Prepared by Bolton & Menk, Inc. <br />
