Oakdale's Comprehensive Sanitary Sewer Plan Update states that <br />Oakdale Sewer District 13 is planned to be served by the WONE <br />Interceptor through Lake Elmo. Part of the District 13 is <br />temporarily connected to the Oakdale sewer system by means of lift <br />stations. The permanent gravity connection to the Lake Elmo <br />system is anticipated before the year 2000. In this regard, <br />Oakdale has requested that this connection be considered in Lake <br />Elmo's Comprehensive Sewer Plan. The sewer system layout is shown <br />on Map 24. The MWCC has made a preliminary determination that the <br />WONE Interceptor can accommodate this additional flow from Oakdale <br />at the Lake Elmo connection point and points downstream. If Lake <br />Elmo agrees to provide this service, an inter -community agreement <br />will be executed before construction would begin. <br />Present flow from Lake Elmo into the WONE Interceptor is estimated <br />by the MWCC at 1.0 MG per year (.0027 MGD).

Indivldual On -Site and Cluster Septic Systems and <br />Packaged Treatment Plant <br />The City has just concluded participation in the nationwide <br />Project 201, implemented to correct deficient private septic <br />systems. Over 200 residences and businesses received new <br />individual systems or were connected to new cluster systems (see <br />,Map _ for location of cluster systems and pertinent design date). <br />� J These systems were consructed with cost sharing by the residents <br />J�f and State and Federal Governments. This effort was an important <br />1�1 part of the City's involvement in the process of eliminating the <br />small percentage of systems which did not meet City standards. <br />1 <br />Those residents determined in the future to have faulty septic <br />systems will be required to upgrade their systems at their own <br />expense. Under the current program the existing ordinances have <br />been upgraded to require regular septic tank pumping and detection <br />of faulty systems. New systems are carefully regulated and most <br />include provision for the installation of back-up facilities. <br />Chapter 701 of the City Code Book relates to the regulation of <br />individual sewage treatment systems. The ordinance requires a <br />site evaluation by the zoning administrator prior to the issuance <br />of a building permit. Also required are soil test and percolation <br />L' <br />
