<br />WASTEWATER TREATMENT <br /> <br />City of Elk River <br />2004 Annual Report <br /> <br />MISSION STATEMENT: <br />To operate the sanitary sewer system in a cost effective and environmentally safe <br />manner. <br /> <br />YEAR IN REVIEW <br /> <br />The collection system was extended by 20,680 feet in <br />2004. This brings the total length of the system up to 67 <br />miles of pipe with 19 lih stations. <br /> <br />In 2004 the control systems in the seven smaller Iihs <br />were upgraded. In addition, the Royal Oaks lih station <br />was rebuilt. The aher hours call-outs to Iih stations <br />continue to decrease. <br /> <br /> <br />The Primary Digester at the Treatment Facility was <br />rebuilt with a new cover, heating and mixing system, and Lob at the Wastewater Treatment P/am <br />control center. This project was carried over into 2005 <br />due to some components having not yet arrived and some problems that occurred with <br />the new system. <br /> <br />A private firm was hired in the summer of 2004 to dry 520,000 gallons of bio-solids. The <br />solids were taken to the landfill by department personnel. In addition, another 350,000 <br />gallons were land applied in the fall. <br /> <br />The department had two full-time operators resign and accept new positions in other <br />communities in 2004. One new employee was hired in November 2004 and another <br />was hired in January 2005. <br /> <br />This past year was very challenging and I believe the treatment facility and collection <br />systems will have to be upgraded and expanded for the next several years. <br /> <br />This past year the department was able to jet vacuum approximately two-thirds of the <br />sewer system. There are certain trouble spots that are done on a regular basis. We will <br />no longer be able to do the entire system each year. <br />
