AE2S, Shank and the City are working to <br />understand why there is the loss of media. (*material used to filter the raw water) <br />Water Treatment Plant 3 was substantially completed in December 2021 and has been <br />the primary water plant in operation for the City. Staff noticed in September, upon taking <br />measurements that slight media loss occurred at WTP 3. Measurements were taken <br />because the same issues were found at WTP 2. AE2S, Shank Constructors and the City <br />are currently working to resolve the media loss at WTP 2. <br />Staff continued to monitor the media at WTP 3. Measurements of the media were taken <br />in August and September of 2021 and in January and February of 2022. While no <br />significant media loss was observed between August and September, this was not the <br />case between September of 2021 and January of 2022. Staff contacted AE2S and <br />requested that this matter be looked into immediately. <br />Further Discussion: <br />Staff contacted another Engineering firm and requested they provide the City with a <br />proposal to review the plans and specifications for the water treatment plants. Staff made <br />this request in order to confirm and explain why there is media loss. Staff informed the <br />City Administrator of this situation on February 3; Council was made aware at the Work <br />Session on February 7, 2022. <br />Staff received a proposal form Barr Engineering for Preliminary Review of Water <br />Treatment Plant Designs for a cost of $10,000.00 to $14,000.00. <br />Strategic Plan Strategy/Goal: Maintain and Plan for Infrastructure Improvements. <br />Ensure Clean Water and Maintenance. <br />Financial Impact: No financial Impact to the 2022 Budget.
