Renovation of a water / sewer project in Lewis Center, Ohio. Completed plans call for the renovation of a water / sewer project.

Staff at the Alum Creek Water Reclamation Facility (ACWRF) have identified needs for improvements at the treatment plant. The plant, constructed in 2001-2002, currently receives an average daily flow of approximately 5.2 MGD. Given the plant has been in operation for approximately 20 years and in being proactive in identifying needs for improvement, the Delaware County Regional Sewer District previously contracted with ms consultants to evaluate potential alternatives related to tertiary and post treatment operations. In general, the improvements considered as part of that evaluation pertain to three main areas: the Post Treatment Building, the Filter Building, and the Administration Building. The evaluation was completed in February, 2022. The following provides a summary of the evaluation along with final recommendations for improvements. Note not all information related to the evaluation and the decisions made are included as part of this engineering report. The total project budget is currently estimated at $3,500,000. In the Post Treatment Building, the existing UV disinfection system has reached the end of its useful life. The evaluation considered proposals provided by four different UV manufacturers, ultimately with a vertical UV system matching the existing system being recommended. Additionally, existing slide gates in the post treatment building are not operating correctly and are in need of replacement. Alternatives for the slide gate materials and actuator manufacturers were evaluated with stainless steel slide gates being selected. Regarding the Filter Building, DCRSD is able to meet their discharge permit requirements without the use of the filters. The filter building is an approximately 14,000 square foot structure and consists of eight (8) filters. Four (4) of the filters are currently non-operational and all of the filters are reaching the end of their useful life with a typical life expectancy of 20 years. Alternatives for the decommissioning of the existing filters and converting the Filter Building into a storage facility for plant maintenance equipment and spare parts for DCRSD's plant and collection system operations were provided. Ultimately, filters 7 and 8 will be converted to temporary storage by filling in the filter bays and placing pre-fabricated panels on top for storage space. ACWRF currently utilizes water furnaces for heating and cooling in the Administration Building and Maintenance Building. Water furnaces are maintenance intensive and costly to operate. Combined with eight (8) water furnaces at ACWRF, DCRSD also has six (6) additional water furnaces at the Olentangy Environmental Control Center (OECC) and Central Maintenance Facility (CMF). A summary of the selected alternative to replace these water furnaces has been provided, which will reduce maintenance and monthly operating costs.
