them often. The small generator is ok to transport but is very old and has a very small <br />fuel tank that only allows for about an hour of running time before it needs to be re- <br />fueled. <br />If the city would have been without power for much longer there would have been some <br />major issues in having only two generators available for nine different stations. Four of <br />the city's sanitary lift stations have long detention times meaning it would take a long <br />period of time to back up into any homes near the station. These four are not high <br />priority in the first few hours following a power outage. They do become factors later on <br />as people continue to use water and flush toilets. The remaining three lift stations need <br />more immediate attention, as they are prone to back ups in a relatively short period of <br />time. In the event of a major rainfall the storm sewer lift station would also need <br />immediate attention if it did not have power so that the pond could be pumped down <br />before it flooded the apartments that are located just in front of the pond on County Road <br />B2. <br />Scenario: <br />Public Works has been asked to prepare a plan for the worst case scenario regarding <br />power outages and what equipment it would take to: <br />A. Keep the water tower from running dry <br />B. Keep sewer from backing up into houses <br />C. Keep water from flooding into Sleepy Hollow Apartments. <br />In the event that all nine stations in the city were out of power for an extended period of <br />time the following priorities have been established: <br />A. Keep water in the tower for residents to use <br />B. Keep high priority lift stations pumping <br />C. Keep the Sleepy Hollow storm sewer lift station pumping <br />D. Monitor low priority lift stations and be ready to pump them when /if necessary <br />E. Hook up power to city hall to allow work to be done such as setting up an EOC <br />Generally, there is enough water in the tower at any given time to allow us at least two to <br />three hours to get everything else in order before we need to start pumping water. That <br />frees up the large generator to hook up to the Keller lift station, which is high priority, <br />and the Sleepy Hollow storm water lift station if a significant amount of rain fell. There <br />is already a problem with our current setup in this scenario. Three high priority stations <br />need attention at the same time and we only have one generator to split between all three. <br />Optimally, we would like to have another large generator to use on the Keller lift station <br />immediately so that we could use the existing large generator at the Sleepy Hollow <br />station for the first two or three hours minimum to pump the pond down as much as <br />possible initially. Once the pond is down, hopefully the rain has let up and we can haul <br />that generator back to the booster station and begin pumping water into the tower. <br />Of the three lift stations connected to single -phase power, the County Road B2 lift station <br />and the Dianna Lane lift station are high priority and need immediate attention with a <br />smaller generator. The addition of a 15,000 watt generator would allow us to hook up <br />3 <br />
