Clerk -Administrator and City Council Page Four of Four sewer main breaks, sewer main leaks, or streets need repair, the owner of the mobile home court must pay for the repair. If the owner of the mobile home court has a problem that needs to be repaired, he can hire the City or hire a private contractor. City staff suspects that these water and sewer systems are not being properly maintained. Specifically, we suspect that a mobile home court may provide more waste water to the sewer than the rest of the City on a per capita basis. This hypothesis comes from the Infiltration and Inflow Study conducted by the City of Mounds View a few years ago. If the waste water flow from a mobile home court is proven to be greater than the rest of the City, the flow may be from infiltration and/or inflow. Infiltration is extraneous water that enters the sanitary sewer usually through leaking pipe joints or cracks in the sewer pipe. Inflow is extraneous water that usually enters the sanitary sewer through holes in manhole covers. I have analyzed installing flow meters to measure the flow from the mobile home courts. The problem with monitoring the flow is that it is expensive because one must install two or three flow meters for each mobile home court. In other words, the sanitary sewer in the mobile home court discharges into the City system at two or three points. My analysis says that the benefits the City can derive by monitoring the flow does not justify the expend- iture. However, the City may want to require the mobile home courts to maintain their infrastructre (i.e., televise and repair the private sanitary sewer lines, etc.) The issue then becomes, should the City require mobile home court owners to maintain their infrastructure according to City stan- dard. After all, they are connected to the City's water system and sewer system and utilize our water and sewer mains. SWT/bc
