Bruce, DISD has already constructed the sewer line to where is connects to the city main, so we are going to need to add an external drop manhole to our plans. I think we have to increase the diameter when we have a drop as well. Why they chose to install the sewer when they can’t go vertical due to lack of water is beyond me, but anyway here we are. Please change the plans and modify the change order. Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857
