RR1� 1V� Upcoming Water Main Maintenance The majority of the city's drinking water system was originally constructed in the 1950's and 1960's, utilizing cast iron pipe. In the 1970's, the pipe materials used changed from cast iron to ductile iron. This older cast iron infrastructure is nearing the end of its useful life and these pipes are becoming more brittle and prone to breaks. A water main break can be both disruptive and costly. As seen in recent stories from St. Paul and Minneapolis, the break can result in water outages for homes and businesses and, in some drastic cases, cause property damage. On average, we experience 30 water main breaks in Roseville every year. As these pipes continue to age, the number of breaks will continue to increase New advancements in the water industry have allowed cities to begin evaluating and using trenchless methods of water main rehabilitation as a viable alternative to open -cut, pipe replacement for some projects. This technology essentially installs a new pipe inside the existing water main without the need to dig up city streets, which results in minimal disruption to residents and the traveling public during construction. The new pipe is a structural improvement that can extend the service life of the existing water main by 50 years. We expect that projects using this technology will eventually be programmed annually for the foreseeable future as our infrastructure continues to age. Project Location City staff has identified two segments in your neighborhood to include in a 2013 rehabilitation project that have a significant history of water main breaks: PHASE 1: Rice Street, from south of Transit Avenue to County Road C -2, has had 8 water main breaks since 2000 PHASE 2: Transit Avenue, from Western Avenue to Rice Street, has had 10 water main breaks since 2000 A project map can be found on the City's website: www.citvofroseville.com/WaterRehab Attachment B Water Main Lining Project- Rice Street Project Schedule- PHASE 1 The Contractor for this project, Veit and Companies, Inc., will begin preparing for Phase 1 of the project this week. They will set up the temporary water system and bring their equipment out to the site. Veit anticipates connecting the temporary water system the This photo shows a typical access pit that you can expect to see on the project. These pits will be barricaded off to protect residents and the traveling public from the construction site. The work on the Rice Street water main is anticipated to last about three weeks from the time the Contractor starts the lining work to time the access pits are restored. -r you oncerns, or comments please contact us at 651- 792 -7003 between 8 am and 4:30 pm.
