<br />Mount Prospect Public Works Department <br />INTEROFFICE MEMORANDUM <br />TO: VILLAGE MANAGER MICHAEL E. JANONIS <br />FROM: WATER & SEWER SUPERINTENDENT <br />DATE: APRIL 29, 2014 <br />SUBJECT: BID RESULTS FOR GEORGE STREET SOUTH SANITARY RELIEF <br />STATION PROJECT (CIP) - ($160,427) <br />Background <br />In the current budget, funds have been requested to rehabilitate the George Street <br />South sanitary relief station. <br />This pumping facility is used to provide relief to the Village-owned sanitary sewer <br />system in the event that the Metropolitan Water Reclamation District of Greater Chicago <br />(MWRDGC) interceptor sewer becomes surcharged. The MWRDGC interceptor sewer <br />system accepts wastewater from Mount Prospect sewers and transports it to treatment <br />plants in Skokie or Des Plaines. During wet weather, interceptor sewers can become <br />full thereby limiting the rate at which they can accept gravity flow from local Mount <br />Prospect sewers. To mitigate the resultant surcharge conditions in our local sewers, <br />relief pumping stations were installed in some neighborhoods. These stations help <br />prevent the MWRDGC interceptors from backing up into local sewers. <br />The George Street South Sanitary Relief Station is located in the George Street right-of- <br />way south of Weller Creek. It was built in 1971 and has been repaired over the years <br />as needed. This station provides sanitary sewer relief for the area from Golf Road to <br />Weller Creek, bounded by South Albert Street on the east and South William Street on <br />the west. <br />Staff created detailed bid specifications and bidding materials necessary to procure the <br />needed retrofits, services and equipment. The improvements include the installation of a <br />complete replacement pump station with new pumps, guide rails and controllers, along <br />with all associated wiring and other electrical control equipment. The standby <br />emergency generator was installed in 2010 is in excellent condition; it will not be <br />replaced as part of this project. <br /> <br />
