FY2022

equipment and takes up space in the digesters needed for active digestion. This will include phosphorous removal, assessment and replacement as needed for the digester complex roofs, 20-year-old heat exchangers and other anaerobic digester equipment as needed. This study will also explore the utilization of food waste and grease trap waste for increase methane gas production, and potential uses for the gas such as generate electricity or produce CNG for vehicle use • Replace the influent pump station bar screen mechanisms with new and include screenings compactors • Make repairs and upgrades to several storm and sanitary lift stations • Continue with the yearly sewer maintenance program and to make repairs of sewer deficiencies as they are found to maintain the integrity of the sanitary sewer • Dewatering roll-off - Pave area for dewatering role-off placed and elevated area. Begin use for dewatering car wash sand loads, drilling fluids and concrete saw waste • Construction of the Nevada Avenue sewer replacement project to begin in calendar year 2021. Because of the location of the sewer, construction coordination with homeowners will be the key to a successful project • Construction of the Scott Boulevard Trunk extension and the American Legion Road improvement will require coordination in making the sanitary sewer connection that will result in the demobilization of the Windsor Height Lift Station and associated force main • Begin work on Melrose Court Sanitary Sewer Improvements. Construction coordination will be the key to a successful project outcome • Continue to support inspection request for new sewer installations within the City prior to acceptance so to reduce issues when the contractor maintenance bond ends • Creating a 5-year sewer maintenance program to better utilize our Sewer Main Replacement fund. This will incorporate the current lining and repair program and capture sewer replacement projects • The WWD is working with the University of Iowa Department of Civil and Environmental Engineering on the development of a technology park to pilot emerging technologies in wastewater treatment and water reclamation. These technologies would be evaluated for real world applications in Iowa communities both large and small rural. Discoveries could be applied here in Iowa and potentially beyond • Continue to offer tours to outside groups, students of all grade levels and student interns so to promote the importance of wastewater treatment as it applies to public safety and to “build the bench” of future professionals in the field of wastewater treatment and water reclamation
