ST0301-CS040804Suzan Taylor - Coppell Road sewer line Page I of 1 From: "Sam Meisner" <sam~freese.com> To: "Suzan Taylor" <staylor~.~ci.coppell.tx.us> Date: 8/4/2004 3:30 PM Subject: Coppell Road sewer line CC: "Tricia Harley" <thh@freese.com>, "Melinda Polley" <mdp~freese.com> Suzan, I've been looking at the design of the sewer line replacement in Coppell Rd and have a question for you. The existing sewer from Bethel Rd to the creek currently flows to the north and includes an aerial crossing at the creek. I've attached a sketch of the area to show the area I am asking about. To keep the existing sewer drainage pattern, it will be necessary to construct a new crossing that will be ~60' long. This crossing will also will be a maintenance problem since there won't be much more than 6-12" of open space below the pipe. I would like to propose replacing this line and making it drain towards the south. This would eliminate the need for the crossing, which could save about $50,000 and eliminate a maintenance problem. There is an existing manhole in Bethel Road that the sewer could be connected to. Is there someone in the utilities group that knows the sewers in that area well? If so, could they tell me if there is enough elevation difference between the existing main and the services to allow the proposed main to be raised? The only sewer service that shows up in our survey is to one of the City buildings, but there are several additional water meters which leads me to believe that there might be sewer services with them. The proposed line would probably have to be raised about 1' at the service labeled in the sketch, and about 2' at the south side of the creek. Do the TV records of the existing line show other services? Would it be possible for someone to pothole any services at the property lines so I can look at the elevation difference? Let me know if this sounds like it is a viable option. Please call me if you have any questions.
