A relief system is needed to serve the Orono Middle School, which is scheduled to open <br />in the Summer / Fall of 2000, <br />To obtain adequate capacity, a 200 gallon per minute lift station is proposed near Washington <br />Scientific on the south side of Highway 12. The lift station would operate on an as-needed basis <br />and pump from the gravity sewer into the Maple Plain Interceptor Forcemain. <br />2335 West Highway 36 - St. Paul, MN 55113 • 651*636*4600 - Fax: 651*636*1311
