This year the District has been getting more often than usual, low level Bacti hits, it is possible this may be occurring because of the age of the UV system. So the District has purchased 12 new complete modules to help alleviate this possible problem. At a cost to the district of over $400,000 dollars. All 12 units have been installed as of August 29th 2022. |

ATT&T was called to see what the problem was. AT&T checked to see if it was something they could fix there. It wasn't, AT&T said they would have to send someone out to fix the line. Work Order # PE4X4317 was implemented to fix the problem.
Also the District has contacted Jacobs Engineering to update our call out system and add an additional safety alarm that will call out if the Win 911 callout system should fail. Attached in attachments in the eSMR is the Jacobs email discussing the work to be done. |
