.~. ~ ~ C h u r c h i l l / Oxford W a t e r m a i n Maintenance P r o j e c t Project Description Over the last year, the City has been working on developing a water main replacement project in your neighborhood, as we have experienced a number of water main breaks on the water main located behind the homes between Lexington and Churchill and Churchill and Oxford. What is the problem? The water main that serves your home was constructed about fifty years ago. These mains are made of cast iron pipe (CIP). The City discontinued using CIP for water main in the mid 1970's. One of the reasons that CIP is no longer used for water systems is that it is a brittle material that is susceptible to breaks. The City currently uses either ductile iron pipe (DIP} or high density polyethylene (HDPE) pipe for water main construction. Ductile iron derives its name from its ductility (bending ability.) This alloy is stronger and less susceptible to damage. What is the solution? The City has hired a contractor, GM Contracting, Inc. to construct new water main within the City's right-of way along Lexington and Churchill using trenchless technology. Trenchless technologies reduce the impacts to yards; however, boring pits will need to be dug to connect the services to the water main and to your homes. By relocating the water main from the rear yards to the City right-of-way, City crews will be able to access the water main for future maintenance without disturbing your back yards. Also, the water main will be constructed of HDPE, reducing or eliminating future breaks and inconveniences to you as our customer. What does this mean? If you live on Lexington, new water main will be constructed behind the curb on the east side of the street. if you live on Churchill, new water main will be constructed behind the curb on the west side of the street. if you live on the west side of Oxford, your water service will be reconnected to the existing water main on Oxford. If you live on the east side of Oxford, there will be no change to your water service. However, the contractor will be setting up their equipment in the right- of- way in front of your home. Any areas disturbed by the project will be restored. Project Update Work on this project starts the week of October 12th, weather permitting. The Contractor will have two crews performing this work. One crew will be working on the mainline. The second crew will be working on services. The following is the anticipated schedule for this project: Week starting 10112: ° Locate existing utili#ies- The contractor will call Gopher State One Call to field locate all of the underground utilities in the project area. ° Oxford Street- The service crew will identify the path and boring pit locations for the new water services.
